Oh, I just watched that video.

1. Flux lowers the temperature of the color.

2. That video only shows how the reflexion of the light from a pair of glasses is seen on a wooden box.

- no talking about what those glasses are, what their coating is, etc.

- no talkking about that box

- no measuring of what the initial color temp is

- no measuring of the initial state, birghtness, etc. of that monitor

- no actual measuring of the blue component of the light.

Also, if the light was originally white, there would be no blue reflection with a typical mirror, or at least no blue reflectionn absorbed to the eye level.

Think about sunglasses. They look blue - similar thing with those in that video.

IT is basically just not proving anything, but that exact situation and results...

Thank you for the info. I've just removed flux; I'm curious how my eyes will react in the evenings.

If you set your brightness comfortably, you shouldn't notice any difference. I keep my brightness extremely high, so I always have a bit more than needed, but then again, this is the only way to live for me...

I have had a Sony 43 X720e for a couple months now and really enjoy it for pc and console gaming. I actually use it more then my LG oled C7 for gaming mainly due to lower lag as my Leo bodnar shows the first bar on the Sony at 11ms and the LG C7 is at 19.8ms and yes I feel a difference between the two :p

Now I am seriously looking into this LG 43ud79 for two reasons:

1: I can remove the AG filter to get a glass front display which I much prefer and the Sony x720e cannot remove the AG filter ( I have tried ) due to a non water based glue for the filter.

2: The LG 43ud79 has 3ms on the top bar with the Leo bodnar and would feel perfect as I have other pc monitors that show the same numbers with my Leo Bodnar and they feel perfect for 60hz displays unlike tvs which still feel way too sluggish in regards to lag.

My question to any owners of the LG 43ud79 is how bad is the vertical banding?

This display is edge lit and those always have some degree of vertical banding that backlit displays like my Sony x720e does not have.

I considered the X720E for a bit before getting my OLED. I'm surprised to see those input lag results though, as rtings lists the Sony as more or less on par with the OLED.

Have you considered the LG UJ series at all? Rtings shows them as having among the lowest amount of input lag if that's what's most important to you, but they are lacking in other areas IMO when it comes to image quality.

I wish you luck if you go for the 43UD79. It sounds like a decent monitor, but at least one person here said that it has a lot of IPS glow. I can't imagine going back to IPS glow and grey blacks after using the OLED, but maybe you're willing to put up with different compromises than I am (nothing wrong with that). :)

Those lag numbers I provided were for the top bar, rtings reports on the middle/average number.

Make no mistake, the Oled picture is infinte amount better then any led tv. I currently have the One X on the oled and it looks bonkers on there!

I may just wait until CES next month to see if LG can lower the lag more on the Oled, that is honestly all that prevents me from using it 100% for gaming. The lag is not bad at 21.2ms but I would prefer it to be around 11ms for the middle bar :)

I just got both the LG and Sony X720E to compare, becuase I wanted to replace my old Dell 3007.

Haven't noticed any vertical banding. But I did notice the PWM I think. Swapping monitors on my desk at the same spot, and roughly the same monitor settings, I always got some eye tension (for lack of a better word) when using the LG, and it was never present with the Sony.

Uniformity looks the same on both? You should notice much lower lag on the LG, right?

The sony has a bug where you hve to go out of game picture mode then back again to get the 19ms lag.

Did you update the LG firmware so it has 480hz pwm? If not then it is running at 120hz pwm which is horrific! The LG should also have much faster pixel response over the x720e, I feel the Sony blurs real bad with movement.

NEws about the Dell P4317Q. THE BURN IN IS NOT PERMANENT.

This thing doesn't get burn-in after 10 days of usage. Not even temporary burn in... It used to get some temporary burn-in, but now it doesn't really get it anymore. Amazing!

I didn't do an in depth analysis, but they seemed about the same. When I had the two monitors side by side with them mirrored, I could see a tiny difference in lag, but when using the Sony by itself, I don't notice it.

Yes, that is the only PITA part of this monitor, and why I am wondering if I should just get the X800E instead.

As far as I could tell, the firmware was already upgraded.

flux is a hoax.

Let's begin with how light affects the eyes.

The larger a surface is, the more light it needs for your eyes for proper focus. Large screens require lots of light for your eyes to view it comfortably.

Small sources of light, on the other hand, are awful for your eyes. A phone on max brightness isn't the same thing. This is all connected to why you should never watch an eclipse dead-on. Eclipses darken the sky, which makes your pupil grow in size. Then, the sun still emits light, from a single point, but still quite strong. Thus burns the eye because the pupil was already in its enlarged size.

On the other hand, a smaller screen at max brightness is worse for your eyes than a large one - if your eyes focus at this relative distance, they need the most light they can get to keep proper focus, otherwise you have a large and dim screen that requires eye strain to see - like Philips BDM4350 which is too dim.

As for why flux is a hoax - it doesn't do anything good. I code a lot, and I am using gray background with grey + green text. Why would I ever want to see that horrible mess that flux makes - it is not better for your eyes since all those new displays have white LED light, and not blue, and it doesn't improve anything. Only makes everything ugly. Might also strain the monitor itself.

Best brightness is the brightness you feel comfortable with though - my eyes require more light because of my room and viewing distance. If yours require less, go with what your body tells you, but don't hold back just because some internet troll told you that high brightness is bad for your eyes. Reading books causes eye damage because they are not bright and because they force the eye. The more light the eye gets, the less strain - people using monitors and electronic screens don't develop eye damage like people reading books do because those panels are lit.

In the video, blue light blocking glasses are reviewed in another video - they basically block blue light by reflecting it. If B component is not set to 0 your monitor is sending energy in blue spectrum to your eyes. Earlier monitors (or ones with sRGB color gamut) send more energy in blue spectrum than any other color, though LG AH-IPS panels are said to be more balanced.

In any case , blue is known to affect your sleep cycle and should be limited at certain times of the day/night. Also there are some theories that blue light carries more energy and could deteriorate optical nerves directly.

You see blue light from anything that has blue color - what degrades your eyes the most is books.

It is purely silly to even think that you can stop that by stopping the blue color from your screen. I would be far more afraid of what it can do to your mind.

blue light is tricky, these tvs arent really meant to be used for the purposes we are using them for, so the amount of blue light they emit is way more than the average pc monitor.

you can turn down the brightness, put on warm colors, and use the windows night mode settings as well as get the blue blocker screen protector. but thats about it.

what would be really interesting is to find out :

Which emits more blue light ; VA or IPS panels ?
Do Edge Lit or Direct lit produce more blue light , and how does local dimming affect blue light production?

The larger the color gamut the less (lower intensity) blue light panel will emit (you can decrease color temperature maintaining decent color gamut). I read that LG AH-IPS technology is using multicolor LED backlight which increases output of red and green spectrum. QLED panels do the same using quantum dot film. Less than sRGB capable monitors on the other output triple amount of blue compared to green and blue.

Many VA panels are sRGB only therefore, probably, emit more blue light than AH-IPS and QLED panels. Interestingly AHVA are IPS (made by AUO) but panels I've seen are closer to sRGB rather than Adobe RGB. Maybe they have not updated their backlight technology yet.

For panels with similar color gamut being equal, edge lit panels likely emit more blue light because they require higher brightness due to lower contrast.

what do you think about OLED & the VA Panels in high end TV's like 900e and blue light ?

You cannot avoid it completely but you can lower color temperature (and/or gamma shift) for tasks that do not require specific white point. Generally speaking, OLED by it's nature emits less 430nm (blue) light than LED except for quantum dot backlights (Samsung QLED, Sony Triluminos) that appear to be caching up with OLED (for colors, not contrast).

Hello all, I got a LG 43UD79 for about a week ago from Costco and have really liked it, I have a couple issues, hope to get some help here

1. I connect the USB-C port to my windows 10 desktop, but I can not charge my phone from the two USB ports on the monitor. I also can not run firmware updates as it says I need a USB connection which I do. I used the USB to USB-C adapter came with the monitor and use a USB-C to USB-C cable. Any one else have this issue?

2. I connect to my PC using DisplayPort and use the OnScreen software to divide the monitor into 4 quarters. this works somewhat well. But I see a vertical line for any video I play, including youtube, in the middle of the picture. The vertical lines disappears if I make the video full screen. Any way I can remove that vertical line?

3. I do not expect to connect more than one device to the monitor, just want to be able to have a big screen real estate to work with. I find the OnScreen tool OK, but not great. Is the next best thing for me to get another video card so I can maybe connect 3 HDMI and 1 DisplayPort from the same PC, is that going to work better? I currently have one DP, one HTML from the video card, one HTML and one VGA in the buildin video. Since VGA is no use, I am short by one.

Thanks for your help in advance.

Why not connect just one DP port from your video card?

how is the flickering / pwm on this monitor ?


I used the Dell p43 which is the same panel and it was so horrible I had to stop every few hours

I am currently doing just that and use OnScreen tool from LG to divide the monitor into 4 quarters. While it works, it does not work very well in Windows 10 for all apps. Some apps work better like Chrome, but others not so much like Adobe reader. Just wondering whether it would work better if the monitor thinks it actually has 4 video sources even though all 4 come from the same device. Hope to see whether others have done that and have pro and cons to share.

Thanks.

You can expect same issue with flicker if you are using at less than 75 brightness. Even at 480Hz (upgraded from 120Hz) flicker gave me a headache. I think gets worse when using PBP - as I did - because while I focused on one side the other side was beaming (flickering) light from a corner (especially bad when one side is dark and other bright). You cannot see the flicker itself but you can see picture 'jumping' (strobe effect) when moving your eyes quickly at low brightness.

this is why I went with Sony even though LG and Samsung's panel look nicer...that eye strain lol

Which model did you get? I need PBP so a TV is not an option for me unless paired with a HDMI multi-view box, but than it gets expensive and I don't know if signal quality suffers.

x800e

ips
10 bit color
pwm free
vesa mounts perfectlt
I absolutely detest those curved screened
.I like flat screens ..
plus with the TV you have a few extra settings to lower the blue lighg

I immediately noticed a difference I can easily sit hours on this screen. and I am do coding development for work


so far this has been this the best purchase bc it's so comfortable to use + blue light comfort + so thin and light can vesa mount this puppy onto a mobile stand so it's a much better deal that big gwasky horrible beast p4317 they call a monitor

The monitor isn't supposed to emit a glowy red image at all times, this can lead to some electron migration over a long period of time. This would be worse with something like full brightness active though, and shouldn't be an issue for most users. might leave a pink / orange tint to it over time, especially with pinkish content that is static.

As for flux, it used to make a difference with older monitors that actually had blue light.

All monitors have blue light. LED monitors actually have to convert blue light to get the other colors.

You aren't as sensitive to blue color, but to pure blue light.

You see blue color because of blue light. So this statement is contradictory.


If you were sensitive to blue color, then rooms that had blue paint would be hard to sleep in, which isn't exactly the case as many homes have their walls painted in blue.

People usually sleep with the lights off.


Basically, some older TN monitors had their light emitting part blue, so any color they emitted was actually blue in realiy, which made the issue pretty bad. Red still was made from blue light passed through a red cell, but the light itself was blue. The issue was not with all colors, but with white, which was blue in fact. This is what led to all white, black and gray to be blue and you were getting a lot of blue with those.

Blue light cannot pass through a red cell, that's why it's there to split the white light into its component parts so we can manipulate those components to achieve any desired shade we might want to see.


Most recent displays, especially after a 300$ price point, are W-LED, which is a white led, which doesn't do the same thing the older blue light ones did. White LEDs emit white light, that is all. So white is white, black is black, gray is gray, you're only getting blue light, if you are watching blue things. And blue color isn't necessarily bad for sleeping, strong blue light is.

W-LED are actually blue LEDs covered with a phospher coating to convert some of the blue light into yellow. Earlier WLEDs still had high peaks in the blue region while later WLEDs are able to convert more blue light into yellow light to create a more balanced emission spectrum.


To return to the point, you shouldn't get any advantage from flux, only worse image, worse image quality, worse colors, makes your expensive monitor just inaccurate, discomfort (it si placebo if you feel you're getting comfort from it. their marketing makes you feel that way, you might actually feel less comfort that way. Like my Dell P4317Q, which gets burn-in if displaying something for too long, but which doesn't get it if images are changing, your eyes prefer not to stare at anything for too long. Red is part of those things, if everything you see is red, it might affect your perception of reality, making you feel slightly nervous, sleepy, dizzy and even anxious, depending on your personal experience). My point is that flux is not exactly bad for Blue-Light monitors, it really made them better, but for white light is unnecessary and doesn't do anything good. You might as well theme your windows in red if you wanted less light or less blue light.

I sleep perfectly at night, and I'm using my monitor at 100% brightness, no flux or such, right before I go to sleep.

Blue light is what makes you're pupils close. So if you reduce the amount of blue light being emitted by a panel, your pupils will dilate and allow more light in making it easier to focus. Blue light is also what regulates our circadian rhythm (you know, because day sky is blue, night sky is black, evolution and all that.). While blue light from a monitor may not be strong enough to disrupt everybody's sleep cycle, it is for some.

Welp , you dont' seem to necessarily contradict me actually. I just don't think that current display tech is dangerous. I don't know much about the sleep cycle and all, but I sleep fairly well (?)

Ah, I see. There is free software that can do that much better. Dell has a strong soft to support that, but Fck it , I'm using everything fullscreen. Loving it. As for your issue, try to look for youtube reviews for it, somebody mentions an amazing software for doing just what you're trying to .

Another pseudo-science site that is far from the truth, Well then.

1. The sun is not blue by any means. It is white AF. Yellowish even. NOT BLUE.

2. The reason why the sky looks blue is very complex and it has way more to do with how the light is filtered by the upper layers of the atmosphere.

3. Neck and back pain are not caused by freaking light,. but by bad computer position.

Qouting more interesting data:

“Some advertisements from lens manufacturers are misleading consumers to believe that blue light from digital devices will cause serious harm to their eyes,” Gordon said. “Products created to block out blue light minimize eyestrain when using computers and digital devices, but have not been tested or shown to prevent any type of eye disease.”

https://www.uab.edu/news/youcanuse/item/7258-debunking-digital-eyestrain-and-blue-light-myths

Please use only actual studies and not pseudo-science and pseudo marketing for a bad product. Yes, eyes might feel a tad more comfortable.

The main issue with blue light is when the white is blue, that is because you take waaaay more if working with word documents, and excel and web sites, and that is because those are white and you get exposed almost only to blue. Respect the 20/20/20 rule because that also helps focus and other stuff.

As to how dangerous is blue light, it is as dangerous as light gets, OFC. All light is dangerous AF

That is the actual study - done on rats. Nocturnal rats. There are tens of things to consider about this damage.

My rule of thumb - if you don't mind flux bad colors, by all means use it! If you don't mind using a PC at low brightness, by all means, use it! IF you don't mind something, you can use it! I do hate low brightness displays with a passion, so I'll keep my position about stuffs.

Is flux bad? Most probably not.

Is it useful? That is not known from any actual study done on primates or humans.

So by all means, if it makes you feel better use it. I dislike it becoming populay because I work in precise color environments and all, so it screws up with what I'm trained to see.

So, using flux is harmless to this monitor? I mean it is just software, right?

It might impose a different strain on the monitor itself, but yeah, as long as you enjoy an ugly picture, by all means, you can use it.

It will change how it looks in 3 years, but are you relaly going to keep it that long?

Okay, I will dig into pubmed regarding this blue light thing. :D One study is just cherry picking so I will aggregate some.

most of this led technology happened within the last 5-10 years and no one really knows what the effect will be like for our eyes after say 20 years of staring at these screens all day

Circadian Rythms:

https://www.nigms.nih.gov/education/pages/Factsheet_CircadianRhythms.aspx

"Circadian rhythms can influence sleep-wake cycles, hormone release, eating habits and digestion, body temperature, and other important bodily functions. Biological clocks that run fast or slow can result in disrupted or abnormal circadian rhythms. Irregular rhythms have been linked to various chronic health conditions, such as sleep disorders, obesity, diabetes, depression, bipolar disorder, and seasonal affective disorder."

With new LED technology available, there's just no good reason to do CAD, text editing or browsing on a 6500k color temp display.

On anything, but a 6500K color temp display*

Because a pure white color is much better than a dirty looking one for the experience as a whole, no?

Of coruse we had :eek:

Because I act like a narcissistic kid about this thing :oops:

Maybe I wanted to have an argument about it actually

As for coming back on those monitors, let's be honest, they will have some flaws (tjhe 43" ones) for a while top come. But does it really matter? Anime on 43" is too nice to miss.

I returned mine, even if one was available for free I would not be able to use it - mainly due to flicker (had bad experience with LG tech support as well)

43" Dell: good quality but flickers and expensive
43" LG: flickers, some report brief screen blacking out, uniformity issues
43" Acer: uniformity issues, retention
43" Phillips: even more screen retention (from what I hear, never seen one)
40 and 43" Samsung TV 6290 and 6300: cheap, good quality, but glossy and no Picture by Picture
Sony TV: too expensive, Triluminos qdot tech is supposedly inferior to QLED by Samsung
Samsung QLED monitors: TN panels...

So with that said think I have to wait a bit longer for mine. Maybe 34 or 36 UHD displays with PBP will come out next year?

EDIT: 40" Samsung is BGR VA panel with decent viewing angles, much better contrast; 43" Samsung is IPS.

On Dell I don't have flicker or PWM, but it is a rare A.02 revision...

Sorry to hear you had to return yours though.... Really sad to hear something like that happened. Maybe you have a chance of using something like a good 31" 4K monitor though?

I don't sense any flickering with mine. I sit in front of my LG 43UD79B for hours every day and have no problems at all. When the monitor was new it also went black for a second once a day or sometimes every second day.
That made me nervous and I almost sent it back. I tried some different high quality cables and settings but it didn't help.
Now the black screens seem to have gone after I downclocked my RAM. Yes, it sounds funny, but I had 16GB running on 3066 Mhz with manually omptimized timings. No problem with my old FHD monitor.
With the 4k LG I set down the frequency to 2966 and set the timings back to standard and have no more black screens.
I'm not a computer expert but maybe the unimportant RAM errors that could be corrected by the system somehow compromised the data stream to the display and it turned off when it detected a change in data rate. Maybe that's just a childish attempt to explain the situation but
what's more important is that the black screens are gone.

Flicker depends on brightness level. Dell claims using their 43" >70 should cause no noticeable flicker. For LG I found >75 to be comfortable but too bright. At levels below 50 flicker 'stings' your eyes and may cause headaches (not everyone is affected equally).

I don't overclock these days but perhaps overclocking RAM affects PCIe bus as well which could cause issues with your graphic card.
