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

    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.

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

    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...

    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...

    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...

    I've had a couple tubes do that flashing upon powering on. When it happens, I'd turn the monitor off immediately, then back on, which seemed to prevent it from going nuts. Dunno if it's related to WPB issue - my guess is probably not. Not sure what's going on with your WPB - so the blacks get...

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

    so the wpb has clearly not done the job for white point, but the LUT adjustment has done a good job. Did the black levels get deeper after the wpb? With the LUT adjustment, what does your gamma curve look like?

    in the guide, I include instructions on how to measure grayscale after calibration (as well as gamma). Look at the section that begins with: HCFR may have changed since I wrote this guide, so not sure if all the instructions map. But basically, you want to ensure your reference white points...

    yea the i1display pro is a great tool, glad you're seeing the benefits! Not sure about what those variables mean, at this point you have travelled deeper down the DAT rabbit hole than I have :p So, just to understand - you've been able to complete a WPB without errors, but the picture doesn't...

    I found dealing with Dat backups and loading to be buggy (on the FW900), so I never really bothered with them. The step where it asks you to achieve a higher luminance (in your case 6.5 nits) with black is normal - that isn't representative of the actual final black value.

    Need some advice for VGA CRT

    sounds like you've made some progress. Make sure your vga cable has a solid connection between video card and monitor - sometimes faulty or loose vga cables can cause strange artifacts, including the glow to the side.

    Need some advice for VGA CRT

    Is your black level really deep? If so, the G2 voltage may be very low (which also would crush the image). But in my experience, G2 tends to drift up (though only have experience with trinitrons) You may be able to adjust the g2 voltage (looks like you might need to raise it). Look up service...

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    Given that this is color calibration and not geometry, you should be fine with the included test patterns. Just make sure they fill your entire screen. During some steps, the actual brightness will automatically be adjusted - so for example even though you're using the black pattern during...
