Instead it reports the “Main” display.
This is causing me an issue with HSM Mega Bezal features that read resolution for mask size, etc. Would it be possible that Retroarch display the information for the display it is running fullscreen on?
How to reproduce:
2 Displays. Main display 1920x1200, 2nd is 4K OLED
Open Retroarch and run fullscreen on 4K TV --> Display info within Retroarch says 1920x1200
“Fix”: Make 4K main Display --> Open Retroarch --> Display info says 4k
HSM then reads this info and makes adjustments to mask size, etc based on this info.
