I recently build a htpc with r3-2200g, but when I connect it with my old plasma 1080i LG tv, I can only get resolution 1240*720 in Win 10 display setting, there is no higher resolution to choose. I had connect the same TV with my intel laptop in same condition(hdmi cabel etc.), there is no issue to correctly display on 1920*1080, same on my PS4, other PC with RX570 either. I have tried everything I can. Update bios, DDU Utility reinstall radeon driver, nothings changed.
The different on DXDiag between r3 and my intel laptop is that the laptop running
“Current Mode: 1920 x 1080 (32 bit) (29Hz)”
R3-2200g running“Current Mode: 1240 x 720 (32 bit) (60Hz)”
But when I set custom detail resolution on r3 using CRU with 1920*1080(30hz) , my TV just go black-screen.
Can someone help me fix this issue?
It's really upset that build a whole PC and it can't work properly.
