After the GFN Patch September 2025 ARM on Super Ultra Wide 5120x1440p seems to not work anymore. When launching GFN itself on ARM, only 3840x1080 is the max resolution working ingame.
When using x64 Architecture, tSUW is available and GFN Input 5120x1440p working Ingame.
Reported that to NVIDIA too, but their Support is really bad. Back and forth just questions back to back with no escalation to a Developer.
The same thing seems to happen here, when launching ARM on 3840x1080, we get back Video Input. When launching ARM on 5120x1440 no video Feed is returned.

What happened?
Windows Build: 25H2
CPU (Surface Pro 10 ARM): Microsoft SQ3 (3.00 GHz)
GPU: Qualcomm(R) Adreno(TM) 8cx Gen 3
After the GFN Patch September 2025 ARM on Super Ultra Wide 5120x1440p seems to not work anymore. When launching GFN itself on ARM, only 3840x1080 is the max resolution working ingame.
When using x64 Architecture, tSUW is available and GFN Input 5120x1440p working Ingame.
That Issue was also raised on reddit (Im Lagger_Gandalf): https://www.reddit.com/r/GeForceNOW/comments/1nwnsq7/gfn_no_longer_opening_in_5120x1440_resolution/
Reported that to NVIDIA too, but their Support is really bad. Back and forth just questions back to back with no escalation to a Developer.
The same thing seems to happen here, when launching ARM on 3840x1080, we get back Video Input. When launching ARM on 5120x1440 no video Feed is returned.
