Hello Guys.
I have problem with 4K resolution after system upgrade.

System Before:
Windows 8.1 pro
Asrock FM2A75 Pro4-M.
AMD A10-5800K
XFX R9 380x
Sony TV with 4K resolution.
Everything was just fine, 4K resolution on desktop and in games.

I bought another motherboard and CPU.
System now:
Windows 10 pro
ASUS H87 PLUS
I5 - 4670K
XFX R9 380x (Adrenalin Edition 18.2.2 drivers)
Same Sony with for 4K.

And now i dont have UHD, only FHD.
When i connect everything (Radeon R9 380X --> HDMI -->4K TV) throught HDMI cable and it shows ONLY FHD. XFX R9 380x drivers is up to date. Is it possible that motherboard have affect on Radeon R9 380X output resolution?
