Hi i been trying to figure out how to get my 6670 to display a 4k resolution but it is not working out i dont know how to get it to work with Custom Resolution Utility if anyone can help me out that would be awesome! for now it just displays 1920 x 1080. If there is no way to get it to work ill have to buy a new graphics card but i dont know where to start i am new at this i just want something that will display a 3840 X 2160 (4k@60Hz) resolution with hdmi 2.0 and my budget is pretty tight (under $100). I am running windows 10 and My processor is the AMD FX 4130 Quad core processor, 3800 Mhz, 2core(s), 4 logical Processor(s) and motherboard is Gigabyte GA***8209;78LMT***8209;USB3 and 8GB of ram im not sure about the PSU yet ill have to check later but i think it is a 430w or maybe a 400w will it even be able to handle a small GPU upgrade?. I bought this pc off amazon already built and ready to go, please if anyone can help me choose the right GPU upgrade for under $100 it would help me out alot. I could have picked one myself but i do not want to get the wrong one and break something in my pc so i am asking for your help please. I mostly want to use this for watching 4k movies and youtube and stuff like that in 4k and a little bit of gaming aswell but mostly for movies and videos thank you!
