Running 5120 x 1440 Resolution on a NUC8i7BEH

I just bought a Samsung C49RG9 ultrawide monitor, whose native resolution is 5120 x 1440. I have been unable to get my NUC8i7BEH to drive the monitor at its native resolution. The resolution does not show up in display resolutions under display settings. When I try to set up a custom resolution in the Intel IRIS Graphics control panel, I get an error "The custom resolution exceeds the maximum bandwidth capacity". I have tried both 60 HZ and 30HZ refresh rate. I have tried using both HDMI and thunderbolt through the USB-C connector. I am running the latest drivers using the latest version of windows 10.

 

What am I doing wrong?

Likely the problem is the cable you are using. Try a better quality, HDMI 2.0-compliant, cable.

Thanks. I have a high quality cable that currently has no problem driving a 4096x2160 monitor @ 60hz. I am also having the same problem on thunderbolt. n.scott, are you running your nuc @ 5120 x 1440?

No. I use a 3840 × 2160 monitor. I am a software engineer, so vertical pixels are much more important. UW monitors offer no value to me.

 

There have been reports of other people fighting to get this resolution working. I can only suggest that you look at the resolutions in these cases.

Thanks n.scot. Any particular forum that you have seen people fighting to get this resolution? All the problems I could find were related to macs

No particular forum; just search for "5120 x 1440" and you should see the various discussions.

 3840 × 2160  is the highest resolution listed as supported in the specs for your NUC.

Thank you for your response. What spec sheet are you looking at? Here are the listed specs I see:: https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i3BE_NUC8i5BE_NUC8i7...

 

The listed specs through HDMI is 4096 x 2160 @ 60 Hz, 24bpp. For DisplayPort via USB Type C the maximum resolution is 4096 x 2304 @ 60 Hz, 24bpp.

 

5120x1440 is lower resolution than 4096x2160

Sorry my mistake. I looked at and out dated spec for the Iris 655.

 

Name-Intel Iris Plus Graphics 655Memory TypeLPDDR3/DDR4 ,4K SupportYes, at 60 Hz,Max number of Display Supported3,Max Resolution4096 X 2304.

 

I think your issue is the 5120 bit...... (out of range so to speak)

That would be a reasonable guess. However, in searching the internet I have seen people using even older versions of the NUC at this resolution. I suspect this may be a driver issue. In another case I notice a user using a NUCi7FNH is having a similar issue. Apparently, version 7262 of the driver works fine, but apparently later versions such as 7529 and 7870 do not. The case can be seen here:

Of course, the NUC10i7FN uses a 620 graphics processor while my NUC8i7BE uses a 655 processor, so the drivers may be different. But the issue may still be related?

I was able to fix it. Turns out it was a driver problem. The last driver to work was version 7372, dated 10/30/2019. The driver can be downloaded from here:
