    WinDAS White Point Balance guide for Sony Trinitron CRTs

    I don't think it matters what you set those to before calibration. The 31/90 is what WinDAS will set the monitor to after calibration (that's what I meant by "should be"). But I believe these values are for the FW900, and that those values may differ depending on tube.

    If memory serves, I consistently get 87 nits in 6500K mode fresh after a WinDAS calibration where I hit all the requested targets (excepting the G2 which I tend to set lower than WinDAS recommends). Can't recall if I've tested that with full field white as well as partial field (full field can...

    I *think* but am not sure, that one of HD Fury's selling points was removal of blu ray encryption, but may be wrong.

    nice. I'll see if I can dig something up for you to test. I've written to the LUT directly using psychtoolbox with MATLAB before, but there may be a simpler way - I think flod may have written a small app, I'll see what I can find.

    Thanks for clarification. It will be a while before I get round to testing the bit depth of those adaptors, but it is something I hope to get done before I die :p

    possibly, but you'd probably need some instruments to probe the circuits. Not sure if there's a simple way to check through software, though I might be wrong. You could also possible use a multimeter to measure the voltages coming out of the output, and test the precision that way.

    Wonder if this means that the Sunix DPU3000 and Delock 87685 may be capable of 10 bit DAC precision.

    Ok that should provide similar results, though I always get much tighter results than you when I use the command line approach (not sure if this is because of the command line approach, or something else).

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    Looking pretty good! How's the image quality? I'm sure you could bundle the information in the cal file into the icc file, but not really understanding your use case. Why not just stick with the cal file you've just created? I also sometimes create a separate cal file for 2.4 and 2.2, and...

    Looks like you're honing in, gj. See what the measurements look like after an argyll lut correction, you'll probably be able to get it dialed in nicely. As for how to improve the low end... on the one hand, your delta Es for 10 is very good, despite the blue channel being out of balance, so it...

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    that's kinda bizarre. And you can visibly tell that the screen is getting dimmer when the colorimeter reports a decrease in luminance, right? It might not be an issue anyway, since I think the last step is for sRGB mode which we don't use (at least I don't). Another question: Did you ensure...

    Moving slider to right increases luminance. If the opposite is happening, something is seriously wrong with your tube, or your copy of WinDAS, or your colorimeter, or HCFR.

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    I don't believe the contrast brightness settings before calibration have an impact. In your first image, the target is 82 cd/m^2 (nits), yet your real time luminance value shows 104.77 nits, and the slider in WinDAS is at max. Why aren't you lowering the slider so you hit the target value?

    One of the key properties of a CRT that many love is the 'pixel softness'. Because of the way that the image is physically rendered, the boundaries of the pixels are not sharp transitions, but rather more gaussian ones that blur together information from neighbouring pixels. This loss of...

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

    My understanding is that some hardware calibrations allow the luminance output (as a function of input voltage) to be tweaked at a few points (out of 256 maximum points). I think that's essentially what's going on with WinDAS. This way, the tube will internally "map" a set of input voltages to...

    Service manual is here. Looks like adjusting voltages isn't straightforward - didn't see anything about a service menu, so not sure how you can do a proper hardware calibration without some knowledge of electronics. That said, you can still get some traction with the OSD and some software...

    Thanks for this valuable information and the templates. I'll update the guide in my signature with the new HCFR flow (it may have been due to older version of HCFR like you suggested, I'll have to confirm), and will include your templates.

    I've never experienced that issue. Wonder if you've got a botched copy of WinDAS, or whether the connection is loose.

    also, you might be able to adjust the voltages (G2, drive), directly with a screwdriver if your tube supports it. I think some tubes have a potentiometer for G2 on the flyback that you can adjust with a screwdiver. Do your due diligence before opening up the tube though (safety, etc.)

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    It does affect gamma. If you set it too low, the image will be crushed (gamma too high). This can be compensated by a software calibration after the hardware calibration, but this works best if you have a 10 bit DAC (nvidia cards with analog out have this). It's been a while since I studied...

    I'm not sure if that monitor has a service manual or service menu. If you can hunt one down that may help.If you're somehow able to adjust the G2, you might be able to achieve what you want. Maybe post in a separate thread with the CRT mode and service manual in the title

    a 10 bit DAC will potentially allow you to gain a fourfold increase in the precision of your LUT adjustments. Instead of being limited to the same set of 256 shades of gray to determine the values for each of the 256 steps per channel, you can now choose from a palette of 1024 shades of gray...

    I'll ask again: Did you rest your LUT before doing the adjustment? When you say you "had to" put G2 around 80, what do you mean?

    Yea I think titan x is the best, but I think 980 Ti is a close second (and arguably better value).

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    Yea it's pretty remarkable how much shadow detail you lose when using 2.4 to view stuff mastered in 2.2. That's why I generally create a couple LUTs. I'd follow jbl's advice, and dive in setting the G2 to a reasonable level (keeping in mind that, at least in my experience, the black level...

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    I trust jbl's experience here over mine, since I've not done any real experimentation on this front. It's a good question though. I'm pretty sure there's a systematic way to achieve a desired target gamma with hardware calibration alone. You could figure it out through modeling of the involved...

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    I bet if you plot your gamma curve it will show a higher than normal gamma. If you want to set G2 low, you have to do a LUT adjustment afterwards to restore gamma to a normal level, else the picture will be crushed. And the best way to do this is with argyllCMS as per my guide (I think there's...

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    I don't think you have to worry about the other color temps if you're not going to use them. I always do all three just because I'm a bit OCD and it only takes a few extra minutes. Curious though, why are you using 9300k and not 6500?
  36. S

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

    Setting G2 too low will cause the gamma to be very high (crushed blacks). This can be compensated for by LUT adjustments, but there are limitations involved with such an approach, depending upon how much crush there is.

    Ah right, yes instrument calibration might not work for dtp-94 (that's what -J does0 https://www.argyllcms.com/doc/dispcal.html

    excellent, that means you have 10 bit precision for LUT adjustments (I have same card as you btw).

    WinDAS White Point Balance guide for Sony Trinitron CRTs

    Also, your black level is 0.1. You can probably bump the G2 a bit lower. The DTP-94 can read as low as 0.01 cd/m^2 I think. Keep in mind that, in my experience, the black level you set during the G2 adjustment is not the same as the resulting black level after the calibration. So you can set the...

    nicely done on the white point. The gamma could use some work though. What video card do you have? If you're unhappy with the gamma, you can use the argyll instructions to dial that in. Use the following: dispcal -m -qm -J -F -G2.4 -f0 (You can use -G2.2 if you like. I sometimes create...
