Looking for settings suggestions

Post by Deex » 01 Feb 2015, 18:30

Hello all, I have a new XL2420Z with v2 firmware. I figured out the basics on how to set this thing up with blurbusters but I still feel that something is missing. The colors seem off and Im not confident I have the best settings.
Currently I am using default "standard" profile with the VT1350 trick. My crosstalk setting is 0 and usually use about 3.0ms persistence.
I am also using a 120Hz refresh rate.

With all that said the blur and speed seem great... the colors picture is what is off. I have been battling with the colors and the gamma/brightness. Everything seems washed out or not being produced well. So I come here looking for some suggestions.
I saw that Falkentyne seemed to know what he was doing so I was hoping for some suggestions from him but I am very much open to anyone's suggestions. Please help! Thanks!~

Also a question to add is: What is the difference between VT1500 and 1350. What are the pros and cons? What does everyone use? Thanks!

Please check out my lengthy response to another user in this post: http://forums.blurbusters.com/viewtopic.php?f=2&t=1870 and see if my suggested settings help :)

Note - this is my personal preference, based on a use case in a constantly dark room so it may be too dark for some people, but as I've said there, with these settings I've managed to get the best colors, especially with the first option (Photo mode).

(edit) I have 2720z
The only difference between VT 1350 and 1500 is that with VT 1500, you MUST use the Nvidia/Ati pixel clock patcher at 120hz refresh rate, and you can get by just barely without it at 100 hz refresh rate (VT 1500 just barely fits at the limit of the pixel clock limit--330.00 MHz; 1502 VT, which is the highest VT possible before you get an out of range black screen, is 330.44 MHz at 100hz and thus will require the patcher).

Vt 1500 gives the panel more time to refresh the pixel transitions than VT 1350 (thus the pixel clock is higher), so you will see a larger cap between the top and bottom strobe crosstalk errors (less crosstalk on the screen) at VT 1500 than at VT 1350. To be more direct, a higher vertical total -increases- the distance between the top crosstalk error strobe pulse and the bottom--or even more directly, it moves the BOTTOM strobe pulse error further off the screen or down the screen, while the top crosstalk strobe pulse error position is not affected (increasing the strobe duty persistence too far past 0.5ms-and I find 1.0ms to be the maximum you can use to keep the top looking good--will move the top crosstalk error too far from the very top of the screen and move it downwards, which can make things get ugly up there).

Any refresh rate under 86 hz that works with VT 1500 will have absolutely ZERO crosstalk at the bottom of the screen (the crosstalk errors will be pushed 100% OFF the screen, while at 100 and 120hz, you can see the very boundary of it with VT 1500 at the bottom, while with VT 1350, more of it is visible).

Besides this, the only drawback to using VT 1500/VT 1502 is:
1) image quality is degraded more than VT 1350; there may be a scanlines effect especially around the top of the screen since the panel is being pushed to its imits. The same scanlines effect can be seen even MORE intensely in Nvidia Lightboost mode, because lightboost accelerates the scanout through hardware (instead of a VT tweak) which improves crosstalk performance even more than a VT 1502 tweak does. This scanlines effect can be pretty distracting in Lightboost mode, but is far less obvious in Benq blur reduction mode, and usually can't be seen except on light white/grey backgrounds, and is usually not a problem.

2) VT 1502 doesn't work on some monitors at certain refresh rates or is unreliable. on XL2720Z, VT 1502 doesn't work at 84 hz refresh rate (causes jittering screen updates, while VT 1500 is perfect. At 85 hz refresh rate, VT 1500 and VT 1502 do not work correctly; causes pulsing or stuttering, but VT 1350 works fine. No idea why 84 hz works with VT 1500 and not 85 hz. This problem does not seem to happen on the XL2411Z or XL2420Z (they are the same panel, the 2720Z is different obviously). 76 hz either works or goes out of range with a VT tweak, seems to be totally random.
On XL2720Z, VT 1502 is hit or miss at 120hz....sometimes its flawless, sometimes its "stutter" (usually shutting off or on the monitor will fix it). This problem does not happen at VT 1500.
VT 1502 is fine at 100 hz.

Which monitor do you two have? What are your settings/configuration?

What suggestions do you have for a XL2420Z?
My main concern is the color as it looks so off compared to any monitor I have ever had.

I said I have a 2720Z. I wrote it clearly in my reply.

I have the same as yours - XL2420Z and posted my settings in the linked thread, but once again - that's just my personal preference, don't take them as the "correct' calibration ;) It's the "best" I managed to do in the Photo mode, but unfortunately in this mode Blur Reduction can't be used :?

Also, what other monitors did you have? IPS panels? Or even 60 Hz TN panels?

Previously a 60Hz TN panel. The last few I have had were 60Hz TN panels.
