I use DP, but it gives me more grief than HDMI. Across multiple devices, cables, and screens, monitors just won't turn back on when waking the PC and it'll force a reboot. It isn't just me either, a search pulls up many forum posts and articles about the issue as well.
I'm probably making a mountain out of a molehill here, but that sort of issue seems like a barrier to more widespread consumer adoption, although the lack of DP on even modern devices is more significant to be certain. I know my friends would look at me like a madman if I suggested they buy a cable that may glitch their PC and doesn't work with any of their other devices.
Anecdotally, I have had the exact opposite problem. All the Displayport stuff I've used has worked flawlessly, and I've had tons of issues with HDMI. It's my dream that everything switched to...
Anecdotally, I have had the exact opposite problem. All the Displayport stuff I've used has worked flawlessly, and I've had tons of issues with HDMI.
It's my dream that everything switched to Displayport, but it'll never happen because we were OK enough with DRM that everything requires HDCP to verify that you're not plugging in something that will record the stream.
I was admittedly a bit young when HD was coming around, were there any strong competitors in the space then? I recall the 5 composite plug, but I forget if that could hit full 1080p. If I had a...

HDMI was basically the less capable cousin to DVI, which was in a sense two HDMI cables and a VGA cable mixed into one. But being as big and bulky as it was, it’s easy to see why it didn’t stick around. DisplayPort is its successor and AFAIK it’s still more capable than HDMI even though newer versions of HDMI have added a lot of improvements.
Analog formats like RGB and Component video are perfectly capable of 1080p and theoretically beyond, but the picture quality won’t likely be better than digital.
Oh my mind was set in thinking about home theater setups, I hadn't thought DVI was really a player there since it didn't carry audio as well. Thank you for your input :)

It's pretty easy to understand why DVI didn't carry video given it was a standard authored by VESA, but integrated audio was HDMI's other "killer app".

I have old monitors so I have to use hdmi to VGA adapters so that my monitors can connect to my graphics card. I've never even noticed a difference, kinda makes me wonder why we needed to switch.

The monitor and graphics drivers are the first places to look for a solution to this kind of problem.
Unlike some others in this thread, I had quite a few "wake-up" issues with my HDMI-connected screens. I usually buy extra cables because those provided by the screen manufacturer are often too short. So I guess I bought the wrong ones... They weren't cheap and I felt ripped off.
When I upgraded my screens last year I checked the certified DisplayPort products list and made sure the cables I bought were listed there. They also cost a pretty penny but I've had no issues whatsoever thus far (either connected through a dock or connected directly) so at least I feel a bit less ripped off and have slightly fewer daily first-world problems.
Thanks for clarifying. I've had persistent GPU driver issues ever since I built this machine, so my assumption has always been that was causing the problem with waking up from sleep. I'd love to...
Thanks for clarifying. I've had persistent GPU driver issues ever since I built this machine, so my assumption has always been that was causing the problem with waking up from sleep. I'd love to go into specifics, but that's rather off topic for this thread, so I'll spare you the details. Suffice it to say I'll be going back to NVIDIA next time I can afford an upgrade.

From what I've read, some folks supposedly had luck with changing their PCI link state power setting to off, whereas others had luck with going into the BIOS and changing the sleep state to S1 (which I haven't bothered with bc I'll just leave it on or full power down if that's my sleep option). Depending on manufacturer, there may be a setting worth trying to toggle in the monitor's OSD, but every manufacturer has their own jargon I can't keep it straight.

Weird. I've had tons of issues with hdmi on my TV, monitors, and pass through for my sound system. DP on my desktop monitors has been the only video cable experience I've never had an issue with.
I've ranted for years to my friends that everything should switch to DP to fix our issues, but maybe cases like yours are why we haven't?
I'd be interest in an investigation to the different issues of each and why everybody seems to have wildly different experiences with it. It took me forever to find a brand of HDMI that wouldn't completely lock up my switch/soundbar/TV setup and require me to shut off the power strip to full reboot everything.
I got an iiyama ... whatever, a 1440p 165Hz monitor. Connected via DP, it sometimes randomly fucks up when turning on and the screen is just random glitches and pixels constantly wobbling around....

Need to turn it off, actually wait 2-3 seconds, then turn it back on. When connected via HDMI it's framerate is capped at 60 for some reason but hey, it's immune to this random glitch.
So yeah I agree. DP is also the only port on my TV any input ever has a problem with. While HDMI just works, on all 3 ports.

I've seen monitors produced within the past year that are still stuck on HDMI 1.4, but if I got the right monitor specs, yours should be HDMI 2.0. It could be the HDMI cable isn't 2.0 capable, or perhaps the graphics card has an older HDMI spec, either of which would restrict your bandwidth and may be why you're seeing that 60Hz cap. Also worth making sure you've got the proper monitor drivers.

I had this problem as well and it drove me nuts. It could be that the affected older Samsung monitor had some sort of lingering design flaw... or the motherboard and video card were disagreeing... or the cable wasn't quite up to snuff... but I just decided to try HDMI cables when trying to troubleshoot the cabling angle. HDMI works but I never did figure out why display port was such a headache.
Strangely enough, that same monitor was fine with an older computer on display port using that same cable.
The issue with newer "cabling" (that being USB C, display port, etc) is that it is difficult to determine what is the problem when something goes wrong. A person can be frustrated trying to get a USB C to HDMI adapter to work and it isn't easy to prove what is wrong without experimentation. It isn't easy to determine what features a port supports, if the cable would even allow for that thing to work, if the device being plugged in will even work without issues, if some software is causing the issues somewhere, and so on. It just makes troubleshooting a bit too much like "just try everything and hope the problem just goes away eventually".
It seemed, to me, like older ancient ports didn't have such headaches. Then again, I may have simply been lucky enough to not run into problems back then.
My main problem with DP is it doesn't play nice with video switching/kvms. There are "display port" KVMs... but when you read the fine print, they all convert to HDMI internally, since the DP...

Composite video is the worst thing to happen to consumer video equipment. Here in America it became the only option for the vast majority of consumer video equipment for well over a decade. So while Europe was enjoying SCART and RGB goodness, America was enjoying fuzzy pictures with bad color reproduction and rainbow banding.

General color reproduction over composite was pretty good by the '90s. But the fuzziness and bleeding never really went away.
S-Video became an option in the late '80s, but I feel like few people ever used it because most equipment just came with a composite cable. S-Video is essentially composite before the luma and chroma signals are combined, and it produces a considerably clearer image. On my PVM, it comes extremely close to RGB when viewing 240p and 480i content. It can actually be a problem for some games which used dithering patterns intended to be smoothed over by the shittiness of composite video.
