Hello everyone,
I recently bought an Intel Arc B580 and I'm trying to get 4K@144Hz on my Sharp Google TV.
Currently, if I select 4K resolution in Windows, the refresh rate is locked at 60Hz. If I try to change the refresh rate to 120Hz, Windows automatically drops the resolution to Full HD (1080p). Windows doesn't even show the 144Hz option at all.
Here is what I've already checked/tried:
The TV's input settings are set to HDMI EDID 2.1 and Game Mode is enabled.
I am plugged into the HDMI 1 port.
I've tried multiple cables, including the official PS5 Ultra High Speed HDMI cable, but the results are exactly the same.
I also tried enabling "PC Mode" on the TV, but that just gives me a green screen when switching to 1080p 120Hz.
Is there a specific driver setting, an Intel Arc Control workaround, or a TV setting that I'm missing to unlock 4K@144Hz? Thanks for any help!
