My brother got my mom a 1440p monitor for her birthday to replace 2 really old 1080p lcd's. I built her computer a while ago but the motherboard only has vga, dvi, and hdmi and I can't find an affordable dvi/dp adapter that can do more than 1080p. Also the monitor won't do 1440p over hdmi so I need suggestions for a super cheap graphics card that has the necessary DisplayPort and maybe even hdmi 2.0 etc. in case a 4K monitor is ever in her future.
