Finally a smart move, a HMD with DisplayPort. I was stunned to see that current PC VR HMD's only use HDMI while Displayport has more bandwidth, which can drive higher resolution displays, and allows for longer cables. This is a headache as many of these high-end videocards haven't got enough HDMI ports.
I thought of getting into it with Oculus'recent summer-offer but decided against it due to it's HDMI-connection (and the fact that my card's 2 HDMI ports are already used). Reading about how troublesome DP to HDMI adaptors might be I decided to wait.
IMHO both Oculus and HTC made a huge mistake by going for HDMI especially for a PC-connected HMD that requires a powerful GPU/system, of which most GPUs just have these unused DP-ports (which have certain advantages for VR). I assume that both companies future HMD units will be DP or HDMI+DP. If not then I'd might be tempted to go for these Pimax units instead.
