    TFTCentral on "fake" HDMI 2.1 and the hdmi org's response saying that's fine

    If you have to pore through a specsheet in the hopes a device does something it probably doesn't do it. It certainly wouldn't do it reliably. Have some trust in the marketing departments of these companies. HDMI 2.1 means the HDMI consortium got paid, nothing more or less.

    24" Widescreen CRT (FW900) From Ebay arrived,Comments.

    ABL and other protections are inactive during the WPB. So if you set things wrong initially the tube can be overbright in later phases. The initial adjustment is not made using instrument data, but the later ones are so if they don't line up redo it from the start. If you do the initial steps in...

    24" Widescreen CRT (FW900) From Ebay arrived,Comments.

    It's entirely possible. Any rich collector in Europe could have put up that amount and by then these were well known and sought after. But it was also supposedly in an attic for that long so the idea of it being "new" old stock may be a bit farfetched as it would've aged enough to be old old...

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    Hey there, despite having done a WPB only recently I've already forgotten the precise details to this step. AFAIK if you meet the luminance targets on all the steps (high and low) you will be fine. It asks to track color accuracy with brightness on full white to confirm that, but contrast I...

    Philips Momentum 55' vs. LG CX

    Well the CX has ABL so on a bright white screen you will get a dimmer image than you are used to with an LCD. In typical viewing like movies or games it'll be about as bright or better than the one you had. It's plenty bright, it's just not 1000 nits like the new displays can do. The Philips is...

    Philips Momentum 55' vs. LG CX

    Well the CX is an OLED with "infinite" contrast and as many dimming zones as it has pixels, but it's not as bright. The Momentum monitor has no FALD so it's just 5000:1 VA contrast at best, though it gets up to 1000 nits maybe. The OLED is a bigger qualitative upgrade for you over your old...

    The tube and power caps still hold charge for some period of time that I can't tell you for certain. Maybe wear rubber gloves for some minor protection. It is fine as long as you don't critically fumble and contact those areas The MOSFETs are located across from the FBT at the bottom of the...

    24" Widescreen CRT (FW900) From Ebay arrived,Comments.

    I had a problem like that with a transistor in the horizontal deflection after a mishap in WinDAS. Q501 I think: The monitor would work until the transistor got too hot and completely shorted out with the burning smell being the first sign. Before I'd had that all figured out, I let it go...

    24" Widescreen CRT (FW900) From Ebay arrived,Comments.

    I attached the North American version of the FW900 service manual, but the components you are talking about probably are unchanged. Anyway I have no experience with that particular issue, but replacing enough relevant components will probably take care of it.

    Sony GDM-FW900 - NIB

    Yeah it's true. 60 nits SDR is an order of magnitude less than most people are used to coming from modern LCDs and the latest OLEDs. So it is dim. Also the instantaneous brightness of CRT is very high for each trace to to produce a coherent image. That's different from having a duty cycle that...

    Sony GDM-FW900 - NIB

    Yeah the total light output of a 48" OLED at 60 nits (cd/m^2) is approximately 2x higher than a 24" CRT (assuming the same aspect ratio) at 120 nits since the OLED has ~4x the area. At the same perceived viewing angle, however, the lux is the same (since the diagonal is only 2x larger). But the...

    24" Widescreen CRT (FW900) From Ebay arrived,Comments.

    Yeah laser projectors and rear projection are a pretty good but they have their own issues, primarily how you deflect the laser light still involves some form of physical device as the photons can't be electromagnetically diverted the way a stream of electrons can. There's also the speckle...

    Sony GDM-FW900 - NIB

    Honestly the FW900 (or any other modern CRT for that matter) doesn't look that great. It looks good, but from the hype job video that DF did (or didn't intend to do), people think it can make 720p look like 8K or something. It does not. Jaggies will still be jaggies at low resolution despite the...

    24" Widescreen CRT (FW900) From Ebay arrived,Comments.

    Yeah the bids are suspicious. Could be a rich collector or a troll. The fact that it was made a private listing means we probably won't ever find out. Even if the buyer were to pay 35K for the monitor, the fees would be exorbitant and the seller would have an incentive to make the transaction in...

    Sony GDM-FW900 - NIB

    Looks like it's been in an attic in Germany for 20 years, who knows if it even works. Private listing so no idea what the bidders are about. Will hit $5000 easy. A used model in what looked to be pristine condition sold for nearly $3500 in Japan just a couple of weeks ago. I'm sure there are...
