Acer Nitro 5 AN515-43 (Ryzen 5 3550H RX 560X) Extend On Second Screen Gives Low Resolution

Hello guys, I've bought this laptop few months ago and as I'm CS student I really need to have second screen, so my life can be easier. So I tried on my 2 TV's(Orion and Hisense dont know the models sorry, if needed I can try to find), both are relatively new, one is on 1080p and other is 4k. On both of them duplicate and other options work fully but when I choose extend the tv screens do work as extended screens but at 480p resolution and its really just like 10x zoomed in desktop. I tried to change resolution on screen but its greyed out and I cant change it. I've tried everything, reinstalling drivers, tried different HDMI cables nothing seemed to work. Would really appreciate any help.

Problem solved. Device Manager -> Firmware -> Update driver. After that it works perfectly.

BTW tried it plugged in and on performance. Doesnt help. It is also recognized as Generic Non-PnP Monitor. Here is picture how it looks on one of TV's.
