Hi guys, I did a search but can't seem to find a definitive answer as to whether SP4 does SINGLE 4k 60hz out of the box. The monitor I plan to use is Dell P2715q. I tried it with my SP3 today, but it maxes out at 4k 30hz. My question is if I get a SP4, will it support 60hz WITHOUT any need to do any driver tweaks / custom resolutions? I've noted that some people have gotten SINGLE 4k to work at 60hz, but it is not clear whether we need to do custom driver tweaks etc. Unfortunately, 4k 30hz is a no go for me... Too jittery. Thanks!!
