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?
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.
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.

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:
