Monitor: Dell UP3214Q Tried driving it originally with my venerable 8800 GTX: no go. My new AMD R290 arrived literally two days ago, and that drives it fine (with tweaks, the drivers are a bit immature). My secondary box (Debian build system) has a second gen i7, with built in graphics (Intel HD 3000): surprisingly, that drives the 4k screen ok as well, although there are noticable problems in VLC/MPV when playing back 4k sample movies: 1080p or lower are fine. Normal (gnome shell 3.10, awesome) desktop operations in 4k are ok. The laptop has that annoying bumblebee thing, with crappy Intel 4600 graphics for the basics - in Win8.1, somehow it can drive the full panel but it buckles under Linux. If I switch to display port (no HDMI output for some reason - it works, but not in 4k mode) and manually enable the beast's Quadro K1100M graphics card, I get full 4k output. I checked, and it turns out I was too hopeful: full 10 bit, Adobe gamut corrected output only happens under Linux, on the laptop, via the Quadro. The r290 in my workstation claims to be in 10 bit mode but it lies; hopefully this will be corrected in the drivers before long. At least before my AMD w9100* arrives :] Her majesty seems strangely unimpressed by my new 4k revelation and is not particularly pleased on my insistence that I need two more 4k screens at approximately 3 grand. I'm working on it. I just need to be super nice for a bit, and then buy them whilst she's not looking...
