December 19, 20169 yr What do you use? Which is better and why? Would I see any difference/benefit going from HDMI to DisplayPort? Or is this just a Ford vs Chevy kind of thing (to use an American automobile analogy), i.e. each has its own following?

December 19, 20169 yr I use HDMI on my main sim machine, and DP on my others, mostly because the older video cards don't have HDMI outputs. With HDMI, quality cabling of the correct spec is important--especially if you want 4K@60Hz. Any DP cable should be able to carry that...not so for all HDMI cables, whose types and specs are often nebulous and/or obsured intentionally on the labelling. Many (most?) 4K TVs do not have DisplayPort connections, but a $20 DP-to-HDMI converter worked well for me while I was experimenting with some Oculus Rift VR goggles (which required the one HDMI port)--I connected the 4K TV via the adapter cable with no issues.

December 19, 20169 yr Who the hell came up with DP? Just when everything seemed to be standardized to HDMI, DP comes in. My video card has three DP ports and one HDMI. Is DP becoming the standard? Most 4K tvs don't have any DP interfaces for that matter not to many monitors either. My main sim display is a 55" 4K and I have three smaller displays which I use a conversion DP to HDMI cable. Works for me. Gnacino
December 19, 20169 yr I'm running triple Dell UltraSharps @ 2550 x 1440. My Titan card has two DVI ports plus one display port. I originally ran a DVI/Display port cable to my third monitor but max resolution was about half. Finally figured it out. I needed a 'Dual Link' cable connected to a display port/DVI adapter which solved the problem. Something to keep in mind. Cheers, Mark
December 19, 20169 yr Just when everything seemed to be standardized to HDMI, DP comes in. DisplayPort has been in existence more than 10 years, since May 2006.

December 19, 20169 yr Commercial Member DisplayPort as I understand it is royalty-free with a smaller form factor than HDMI. The only thing that HDMI has that DP does not is an Audio Return Channel, which makes sense in a TV/AV world but not with computer displays. Cheers!
