    You did unleash the seeds of a revolution in my own mind. It may be while before I get round to it, but you gave me hope and inspiration :)

    I can objectively test your hypothesis by taking some measurements to see the area of desaturation. Might have time to do it this wknd.

    By corner, meant the corners of the gamut as visualized on the CIE 1931 color space chromaticity diagram, which represent the chromaticity of the primaries of the relevant color space (in this case, Rec 709). And yes, if you have a white box next to a red box, there is going to be significant...

    I'm not convinced that that color purity is affected by light pollution from nearby phosphors (whether due to electron backscatter or internal reflections). I've taken several chromaticity (and spectral, using a spectroradiometer) measurements of primary color patches, and the readings are right...

    yea, just looked up a couple plots - the green and red are both shifted in hue and saturation, and overall gamut is smaller in 601.

    My understanding is that the gamut of CRTs is quite limited: the BVM's phosphors were in line with BT.601, which is slightly diff from 709 (if memory serves, one of the primaries is slightly less saturated than the corresponding 709 primary). Yes, color purity will be affected by bleeding with...

    When you mention color, are you referring to the limited color gamut of CRTs relative to wide gamut workflows? Or something else?

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    I've had a couple units that started to give me an issue that might be related. When I turned on the screen it would become very bright (red in my case), and I'd need to turn it off and then on again to stop it. Looks like when you turned it off and then back on it didn't get as bright, so may...

    This should help.

    on the FW900, there is a second step where you do the same thing, but I believe only the green gun is active. Perhaps this step doesn't exist on the F520. My thinking was that the poor results you're experiencing may have been due to the two steps being adjusted differently relative to each...

    Were you using a colorimeter? Also, what approach did you use to set the G2 levels during those first two early steps? (one where there is black, and one with a greenish black)

    If you're sure that the cable is good (with drivers if you need them), then not sure - sounds like it could be the tube (EEPROM, or something else). One thing I can say is that I've had issues with my tubes when trying to load DAT files - it doesn't seem like a reliable way to store...

    congrats on snagging one of these tubes! Not sure what's going on here, but maybe try a different copy of windas. Maybe try the one in the video description here: (also has instructions on how to get it to work in non xp versions of windows) Also, check video description in this one for some...

    Not sure what's going on with your 454, looks strange. To clarify, those moving lines are visible to you right? (i.e. they're not an artifact of refresh rate interacting with camera framerate). As for the click and refocus with your other crt, many people here, including myself, have...
