Is it possible to set a custom resolution of 1440p for the Intel Arc B580 on a 1080p monitor?

I own a 1080p monitor (AOC 24G11E) and I'm looking to benchmark a game at 1440p to check if it reduces the overhead problem that occurs at 1080p. Is it possible to set a custom resolution that my monitor doesn't officially support?

Basically yes. But it depends on your monitor what it accepts. You can play with this, nothing can break permanently:

However, it is advisable to have a second display device in reserve in case the resync with a new self-created resolution fails. If you have a second computer on the network, you can also establish a remote connection. Or boot Windows into Safe Mode in case of issues caused by EDID overrides. Please read the first page of the link.

Hi! I'm going to give this app you recommended a shot, but I'm a bit worried it might not work. I don’t have a second display available, but I can use my pen display tablet if that doesn’t work. If it’s not too much trouble, would you mind sharing a simple tutorial on how to use it? I would really appreciate it, but only if you're not busy.

AOC 24G11E
1920 × 1080 @ 180Hz
1 x HDMI 2.0
1 x DisplayPort 1.4

 

Please connect the Arc B580 and the monitor with a DisplayPort cable and run edid-test.exe:

https://www.monitortests.com/edid-test.zip

 

This will create a file named "edid-test.txt" in the same folder. Please attach this TXT file here.

 

Don't worry. This data is just encoded data of the information sent from the monitor to your PC. No personal data or other system information is read through it.

The monitor has a native resolution of 1920 x 1080 as stated in the leaflet. You cannot expect a monitor to support a higher resolution than its native resolution. Some monitors can scale down higher resolutions, but not all monitors accept higher resolutions.

 

  1. The monitor expects Coordinated Video Timing - Reduced Blanking (CVT-RB) for 1920 x 1080 @ 120 Hz. Exception: The vertical sync polarity is positive instead of negative.
  2. The original data shows a 600 MHz limit for the pixel clock.
  3. The original data shows a 200 kHz limit for the horizontal frequency.

 

Under these circumstances, it would at least be possible to feed the monitor a 2560 x 1440 @ 120 Hz (CVT-RB) signal with positive sync polarity to see if it somehow accepts and processes it. But this is highly experimental!

 

If you want to try this out, follow these steps:

 

  • Download the EDID file attached (EDID_24G11E_mod_01.txt)
  • Download Custom Resolution Utility (CRU)
  • Run CRU.exe
  • Make sure the active EDID is AOC2411 connected to your PC

  • Close CRU with OK and restart the computer.
  • When the PC boots up and Windows loads, 1920 x 1080 @ 180 Hz should be the default setting.

 

Note:

If you now select 2560 x 1440 in the Windows display settings and the monitor remains black or shows some kind of disorder, just wait 15 seconds without any input and Windows will restore the previously active signal.

 

Note:
All changes made with CRU can be undone if necessary by running "reset-all.exe" from the CRU download package and restarting the system. You can find more information about this tool on the linked page.
