XL2411Z, Can't create custom resolution.

[dystopia]

Hey people,
I'm completly new to this so please forgive my ignorance.

I've set up my monitor to the point that I got the Strobe Utility Tool running finely. Now, I read that one should create a custom resolution and adjust the number of vertical pixels to 1350 or (according to https://www.youtube.com/watch?v=ZvsmO5cjB6A) even to 1502. Well, I tried that in the NVIDIA control panel.

Here is what I did: Clicked "Customize...", then "Create Custom Resolution". Selected 1920 and 1080 in the top row, 120hz below that.
Set the timing to "Manual" and finally, changed the number at Total pixels Vertical to 1350.

It doesn't work. The error messge reads "Test failed. Custom Resolution 1920 x 1080 (32-bit) is not supported by your display." The same happens when I change that value to 1502.
Oh and by the way, im using the v3 Firmware.

Help would be appreciated. Thanks in advance

EDIT: Actually, I just opened the Service Menu (the one where you restart the monitor while holding down the 2nd key) and it shows no difference whatsoever when I adjust my values in the Utility Tool, so I assume that it doesn't even work right. Halp.

EDIT #2: Edit #1 is irrelevant, I fixed that issue.

I don't have an Nvidia card, but I know the Nvidia control panel has some really strange settings possible.
What you can do is use the much easier and more simply ToastyX CRU (Custom resolution utility), download the driver restarter also AND download the pixel clock patcher for Nvidia.

Before I continue, it's VERY possible that the reason you can't create that custom resolution is, you're using 120 hz refresh rate and a Vertical total of 1350 or 1502 will exceed the 330.00 MHz DVI dual link bandwidtdh limit. Someone said the Nvidia drivers automatically allow you to exceed this, but I don't know. My laptop doesn't even have a DVI port, anyway..

So you can try running the ToastyX Nvidia pixel clock patcher first and then create your custom resolution and see if that works.

If it stilli doesn't work, then just use CRU, click add under detailed resolutions and click manual and create a 1920x1080@120hz, with front porch 48/3, sync width 32/5, horizontal total 2080 and VT 1502 (or 1500 or 1350), 1502 gives the most effect of crosstalk reduction from top to bottom, but there's no visual difference between VT 1502 and VT 1500 (although a few refresh rates may look funky with VT 1502 but be fine at VT 1500).

Note that in CRU, you will see that the default timings will be 88/4 for front porch and 44/5 for sync width, and Horizontal total may default to 2200 instead of 2080. I honestly don't know if that's an Nvidia thing or an AMD thing, but for a VT 1500 at 100 hz, you can use the default (88/4, 44/5, 2200 HT) at 1500 (not 1502) to get exactly 330.00 MHz bandwidth and not even need a pixel clock patcher.
But if you try using the default (88/4, etc) at 120hz, your bandwidth will be 396 MHz (with the pixel clock patcher), which may cause display corruption. reducing this to what the Nvidia drivers seem to like (48/3, 32/5, 2080 HT, 1500 VT), will lower the pixel clock to 374 MHz which will work just fine. Do NOT turn off instant mode at this pixel clock--the screen will go crazy.

After any change in toastyX's CRU, you can run the driver restarter to apply the changes, but remember to run the PIXEL CLOCK PATCHER FIRST, if any of your VT changes exceed 330.00 MHz bandwidth (restarting the driver with restart.zip also will apply the clock patch to the driver file to be reloaded).

The pixel clock patcher fixed my problem, thank you very much!

Glad it worked!

Okay, I actually got another question.

I like to use 1280x960 or 1024x768 as resolutions in CS:GO (there are various reasons for it - getting above 120fps constantly, better feel for me, bigger looking models, ...). How do I go about creating a custom resolution for those? If I set the same values as for 1920x1080 it looks all messy

[Falkentyne]

I recommend 1440x1080, 1125 VT, manual (not automatic) detailed resolution for CS: go; as this is the highest true 4:3 resolution for a 1080p display.

In CRU, creating 1024x768@100hz or 120hz (under standard resolutions, do NOT do this under detailed resolutions or try a VT tweak; it wont work right) and 1152x864 work fine. But you need to set the video card drivers to stretch image to full panel size first. Then when you run a DX9 game (only DX9 games work with custom resolutions lower than 1920x1080), go into the monitor OSD display mode and select 1:1. If the monitor isn't fed a full screen 1024x768 or 1152x864 image after you create it as a custom resolution, e.g. if the video card is set to preserve aspect ratio, then the OSD's 1:1 or aspect won't scale it correctly since the image will be aspect to begin with.

1280x960 (as a custom resolution) doesn't work on my 2720Z. Only the GPU scaled (default one) does. If I create a 1280x960, the OSD reports 640x960, and the screen is actually in 640x960 resolution with the video card outputting 1280x960. NOT pretty.

The best DX9 4:3 custom resolution for CS and other games (Unreal Tournament, etc) is 1440x1080. That gives you black borders at the left and right but perfect and full size 1:1 with the top and bottom fully used.

Create that as a manual detailed resolution (not automatic! If you create it as automatic, your monitor's 1:1 and aspect scaling settings will become greyed out and you will have to use the video card settings instead). 1440x1080, with 1125 vertical total, 100 or 120hz, then select 1440x1080 in CS:Go, and go into the monitor OSD and select 1:1 and you'll really love the results. (don't select aspect, even though in this case, aspect is IDENTICAL to 1:1, because if you alt tab to the desktop and are using a VT tweak, aspect (which should be disabled and greyed out at 1920x1080, is AVAILIABLE (Osd bug, when using out of specificiation timings) and will run the desktop at a reduced screen width. 1:1 is still greyed out (thankfully) so the default (full) will be used.
