I have two 4k displays that (claim to) support HDR/10-bit color. One display takes HDMI only, the other takes HDMI or DisplayPort. I want a graphics card that will drive both of them to 4k HDR under Windows 10.
I don't do any gaming so I don't care about frame-rates. I mostly want HDR for photo and light video editing, so I'm also guessing that GPU memory doesn't matter.
Computer is a Dell Inspiron 3668 with i7-7700 and 32GB RAM.
