BENQ XL2411z Changing Timing Forces 4:3 1920x1080 display!!!

Post by Corgi_ » 20 Aug 2016, 08:02

So basically after following this thread's tips, https://www.reddit.com/r/pcmasterrace/c ... onitor_to/ , my monitor forces 4:3 1920x1080p 120hz display after changing the vertical timing to 1350 or 1502. I have a video demonstrating the problem, http://www.youtube.com/watch?v=_WkVCPFITBY . I have tried everything I have found on the web, but mostly I see black screen problems and no answers to mine. Any answer would be appreciated. my monitors firmware version is v4, also connected with a dl dvi

Easy solution:
Go to picture advanced and display mode and set it to fullscreen.

Changing the vertical total make the monitor think that 1080p isn't the native resolution so "Aspect" becomes available when it should be greyed out at 1920x1080.

Black screen problems only happen monitor side when enabling blur reduction. Using a VT tweak limits the maximum value for "Strobe Phase" from 100 to a lower number. Those limits are explained in the sticky in the General forum section.

Thanks man, hadnt noticed i could do that, however I play cs;go on 4:3 blackbars, i guess I can just force my screen to display on 4:3. Thanks for your help mate, very happy :).

If you want 4:3 in CS:Go, you should be using 1440x1080 resolution. This is the 4:3 version of 1080p.
Then you would set "1:1" or "Aspect" in Display Mode (these are the exact same thing in this case). Setting "full" would stretch 1440x1080 to 16:9 which looks bad.

There are some problems with getting 1440x1080 to unlock 1:1 and Aspect via display scaling (in the monitor) due to how the firmware works, because "1080" is supposed to be native vertical. For 144hz (which you can't create via a custom resolution directly), you can just create a 60hz 1440x1080 and just enable GPU scaling on the video card drivers (so it's scaled from 1920x1080) and use the video card aspect settings instead. You can also do this for 100hz and 120hz if you don't mind GPU scaling. One "benefit" of this is that the VT tweaks you may have used for blur reduction will still work, as the resolution is "still" 1920x1080, just downscaled by the video card itself.

For 1440x1080 display scaled (monitor scaled), I couldn't get it working at 100hz easily without blur reduction being slightly "blurred" by using a VT designed for 75hz (VT 1114 or 1117 I forgot). For 120hz, this works:
1440x1080, Vertical Total 1125. Then 1:1 and Aspect become unlocked in the monitor settings.

Wow, thanks for the reply, will definitely use your tip!!!

Thank you. Maybe I should be more specific on creating custom resolutions.

Some people have said that using the Nvidia Control Panel to create custom resolutions or create Vertical Total tweaks for blur reduction lower Strobe Crosstalk causes 'weirdness', like dizziness when using "vertical total" tweaks, strange behavior, or being able to do stuff like set 180hz refresh rate on a XL2411Z monitor, making games/windows think it's 180hz but it's actually 144hz (you can guess how bizarre things would look as everything would be out of sync and messed up).

I can't help with "extension blocks" on Nvidia cards (you need to read the ToastyX CRU forums for this yourself, I have an AMD video card), but as far as a 1440x1080 custom resolution, you can enter a 120hz display scaled (monitor override) timing under detailed resolutions:
1440x1080
porch 48, 3
Sync 32, 5
Horizontal/Vertical Total 1720, 1125
Refresh 120hz

This will create a display scaled 1440x1080@120hz resolution, with 1:1 and aspect available in the monitor OSD. This will give you your 4:3 with vertical black bars. and full size top to bottom. Never use "full" setting, otherwise you would be better off at 1920x1080.

Then all of the other refresh rates (60hz, 100hz, 144hz) will be automatically GPU scaled, since the other refresh rates are added by the driver. For the GPU scaled ones, you would set 1:1/Aspect from the video card Nvidia driver settings. The display scaled one will be ignored by the driver because the monitor handles it. Make sure to set the strobe phase to 000 if you have it tweaked for a different value if you're using display scaling and blur reduction.

If you want to use 1440x1080@120hz with GPU scaling, just enable GPU scaling in the Nvidia CP, then use the same aspect settings in the driver like the other refresh rates.
