My goal for this project is to have an OpenBSD workstation (I run -current) built around 4k displays. I have a Dell P4317W 4k display on order and I am going to order a couple of other 4k displays as well. I have a Radeon HD 6870 Eyefinity 6 card which should be supported by radeondrm(4) but it does not support 4k displays at 60Hz. There is a Radeon HD 7750 card that also has six Mini DisplayPort connectors and does support 4k displays but I am not totally clear if it will work well with radeondrm(4). Reading the archives is not quite clear on this.
The alternative is to use a Skylake processor with integrated graphics and use efifb(4) and wsfb(4) for now which I presume would work well enough although not as well as something supported by inteldrm(4). I am using my ThinkPad X260 with efifb(4) and wsfb(4) which works pretty well but it would be nice to have properly accelerated Xorg. Any recommendations? Thank you. Bryan
