I dont know how, though.

I don't know what you're asking. CRU only deals with individual monitors. You need to use AMD Eyefinity or NVIDIA Surround to combine displays.

I know. But Nvidia Surround doesnt show any Resolution as an option. Beside one 3000x700 (dont remember the exact resolution). Then i found your nice program and wonder if it can help.
Seen a guy who used your program to get the wished resolution into Nvidia Surround option. But he used the extension blocks. Dont know if its normally used for that.

You need to be more clear about what you're trying to do. You didn't say anything about NVIDIA Surround initially, and you haven't explained what this guy did or what this has to do with TV resolutions, so I have no idea what you're talking about.

The problem is NVIDIA Surround does not support mismatched resolutions, so it's probably using the highest common resolution that's available on all the monitors, such as 1024x768, which would give you 3072x768 with three monitors.

You can try using CRU to add the same resolution with the same timing parameters to all three monitors, but G-SYNC monitors often don't support non-native resolutions (lower resolutions use GPU scaling), so I'm not sure if this is possible.

AMD Eyefinity doesn't have this limitation, but mixing resolutions can cause tearing issues because the monitors can't be synchronized. Usually it's best to have matching monitors for Surround/Eyefinity.

Ok. Thank you a lot for your answers and your time. That helped.

Hello, everyone. I'm having a hard time trying to set the native display resolution of a lg29um68 monitor, which is 2560x1080, in Windows 10, using CRU. The maximum resolution I could set until now was 1920x1080.

I have a Intel Iris Plus Graphics Card, driver version 26.20.100.7463 (the last one supported by Dell), integrated with Intel corei7-1065G7 CPU in a Dell laptop. According to Intel, the maximum resolution supported (HDMI 1.4) should be 4096 x 2304.

But the native resolution of the monitor (2560x1080) doesn't show up at the "display resolution" drop down menu, after right-clicking on the desktop.

The problem is not the HDMI cable, as I have used it to connect another old laptop to this monitor without any problem.

Opening the software "Intel Graphics Command Center", I managed to create a custom resolution (2560x1080), but it doesn't work, and it doesn't show up at the "display resolution" drop down menu.

Running the Custom Resolution Utility, I wasn't able to add a standard resolution of 2560x1080.

Does anyone have any idea that could help?

You don't need to add it as a standard resolution because it already exists as a detailed resolution. The problem sounds like a 165 MHz pixel clock limit, which shouldn't happen with HDMI 1.4. Try importing the hdmi.dat file. If that doesn't help, the only workaround I can think of is to change the detailed resolution to 50 Hz.

ToastyX, unfortunately, as I imported the hdmi.dat fite and restarted the graphics card, the monitor showed a message that no signal was beeing sent. Then I deleted the extension block, changed the detailed resolution to 50Hz and restarted the graphics card again, but I couldn`t change the screen resolution to 2560x1080.
Anyway, thank you for your time and for trying to help.

Something is screwy with the graphics driver because that's not the expected behavior. Try importing hdmi.dat again and then use the "Copy" and "Paste" buttons at the top to copy everything to all the duplicate monitor entries. I've heard this might be necessary in some cases with the DCH drivers. If that doesn't help, try 50 Hz again with the copy and paste method, both with and without the extension block.

Hello, how are you ? so i wonder if these timings are correct for my 144hz "Acer KG241Q Pbiip" monitor, when using the HDMI cable the timings shows like any other conventional 144hz monitor, when using the displayport cable, it looks very different from the conventional one.
In HDMI:
Horizontal Vertical
Front porch: 24 Front Porch: 3
Sync Width: 32 Sync Width: 5
Back Porch: 80 Back Porch: 10
Blanking: 136 Blanking: 18
Total: 2056 Total: 1098
Sync Polarity: +/+
Refresh Rate: 144.000HZ
Horizontal: 158.112HZ
Pixel Clock: 325.08MHZ

The DisplayPort timing parameters match the CVT-RB2 standard, except the sync polarity is -/+ instead of +/-, which isn't important. The HDMI timing parameters are non-standard, probably to reduce the pixel clock, but that's not a concern. AMD's new control panel has a bug that incorrectly lists the vertical front porch with the resolution added. 1143 - 1080 = 63

Yes, I had noticed since the 2020 driver adrenaline rush, but then are these displayport times normal? I also noticed that amd always sets the CVT-RB sync polarity to - / + instead of +/- by default,
Another thing I find strange, when changing the resolution in-game or windows, the monitor will keep reporting as if it was 1080p 144hz and not appearing to be changing resolution, because the Alt key is too fast.
