So, I'm helping a friend build to build his computer and I gave him a list of specs that could be great for him. But because he can't afford to buy them all at once, he is saving for each part and buys them seperatly, as soon as he has the money for one. This week he bought the the graphic card, a Gigabyte GTX 960 Windforce OC. He installed it but it seems to be a problem with the resolution, even after installing the appropiate drivers. The image looks scaled and kind of blurry, and the card doesn't recognize the display's native resultion properly. The drivers detect it like it's 1920x1080 but it definitely isn't. When he was playing with a VGA connection (yes, VGA in 2016) its native resolution was recognized at 1440x900 (with a GT 730), but when he changed the card and the connection (he has upgraded the connection to HDMI) these problems appeared.
Another problem he has is the framerate. He tried to play CS:GO and his framerate was the same (30-40 fps) with low and maximum settings and different resolution.
I tried to reinstall the drivers, check if something was not connected properly but I couldn't find any apparent problems. Personally, i think it's an incompatibility with the motherboard or something, but i'm not sure. I'll list the specs down below and I hope you guys can help me! Thank you very much!
Motherboard: ASRock G41C-GS
RAM: 4GB of DDR2 RAM
CPU: Inter Core 2 6600 @ 2.4 GHz
GPU: Gigabyte GTX 960 Windforce OC (before GT 730)
