Low refresh rates for UWP screen modes

Open madebr opened this issue 2 years ago • 1 comments

On my Windows system, the output of testdisplayinfo, when using the winrt video driver is:

The 4.77Hz refresh rate seems off.

For reference, the output of a native testdisplayinfo is:

Also, is the difference in format expected?

Nope, that seems wrong.

This is fixed!
