Nvidia surround detects 4k instead of the native 1440p for multiple monitors


I was told by Nvidia support to come here and ask for help. I have three BenQ EX3203R’s that are native 1440p monitors being driven by a Nvidia RTX 3080. They detect as native 1440p monitors in Windows 10 with the latest WHQL driver but when I try to use Nvidia Surround, it calculates the three for a total of 11520x2160 instead of 7680x1440. The option to add a resolution is greyed out. I’ve used the Nvidia cleanup tool, latest drivers and to no avail as per Nvidia support’s direction. I have the three monitors connected via DisplayPort but have tried one of them with HDMI which made no difference as others have suggested via Google searches. When searching for this issue, there are other people with 3080’s and 3090’s that are affected. Hope you can help!

Here is a thread from other users on the nvidia forums:


I have had the same problem for a long time. I think it’s a problem on Benq’s side as the driver seems to report the resolution 3840x2160 to windows. I think it can be worked around using CRU (Custom Resolution Tool), but I found a simpler way, at least if you don’t have to switch between triples and VR all the time, in which case it doesn’t work well.

If you enter Nvidia control panel and go to Configure Surround → Configure. Select your topology and your screens. Then enable surround with the resolution 11520x2160. The result will look garbled, but when it has finished after a few seconds you will see that the small button on top od the resolution dropdown will enable. If you press that, you will be able to add your resolution, I suppose it is 7680x1440. MAke sure you can see that resolution in the ‘active’ resolutions section. Press OK. Now you can select the correct resolution in the dropdown. Select it and press ‘Apply’. You should now have surround activated with the correct resolution. IT shall also be possible to select the correct refresh rate (144/120 Hz depending on which Freesynd mode the monitor is in).

Hope this helps.

Thanks John! Your solution works well.
