The main disadvantage of DP over HDMI is that if you switch off a monitor that is connected to the computer via DP, then the computer thinks the monitor has been disconnected, and rearranges all your windows for you, so when you come back to the computer and switch the monitor back on it's all messed up. With HDMI, that doesn't happen.
- Fnoord 6y agoTrue, that can be a disadvantage (can also be an advantage though).
- smileybarry 6y agoIn my case this was an advantage because my previous GPU had a bug where presence detection for HDMI was only done on boot. So if I forgot to switch my display on before UEFI or before Windows boot manager started, it would boot headless. With DisplayPort you have to unplug & replug at best (though on/off should work because of what you described, not to mention detecting a new display when it powers on).

Also some people have pointed out a few displayport edid emulators keep the appropriate signals up to prevent Windows from thinking the monitor is off. I haven't tested it yet as when I first ran into this problem I just switched back to DVI, but a recent Windows or nVidia update (ha - timely with the article) caused my GPU driver to constantly crash with DVI, but when I switched back to DP it now works just fine. Sigh. I guess I do need to see if I can find the right kind of EDID emulator after all.
- wolrah 6y agoThis has nothing to do with DisplayPort itself and everything to do with a bad implementation in the monitor. The DisplayPort spec actually explicitly says to not do what these defective monitors are doing.
