Why do people still love DisplayPort when it has a catastrophic hot plug issue

[JuJuYuJu]

People using multi-monitor setups would probably experienced this issue before, displayport devices would "disconnect/connect" on power on/off and would move all windows to another display. I replaced my monitor just because of this problem and HDMI 2.0 works great until....its the time for a GPU upgrade. Currently my Gigabyte 1050Ti G1 Gaming has 3 HDMI ports and all of them are used, and trying to find a card with more than 2 HDMI ports is just not possible at this price range ($300 - $500CAD). 

 

Any thoughts on why people still prefer DP over HDMI when it has this serious issue? 

[NineEyeRon]

People love DP.

 

I have DP at work, I had the issue you mentioned but don't get the issue with DP at home.

 

[Skiiwee29]

Ive had no issues with what you described ever. 

[JuJuYuJu]

I was stuck with my PB287Q on DP for around 4 years, switched to a 34UM88C-P this year and its like the best feeling ever to use HDMI 2.0 LOL, just tried DP with it and same issue occurs. GPU and cable were replaced while with the PB287Q, same issue occurs. I just wish GPU manufacturers could make more cards with more HDMI ports on the lower end.

[SpookyCitrus]

I have never had an issue even remotely similar to that with DP before. I have had other problems with DP before but they were all from the DP cable in question being of poor quality. If you have issues with DP see if replacing the DP cable with a higher quality cable fixes the issue.

To be honest, why use DisplayPort when you're not going to take advantage of it, whether it be high refresh or high resolution, which is why I stick with HDMI.

[Princess Luna]

I use DisplayPort so I can use G-Sync compatible on FreeSync.

[John_Trollinski]

I have no problem with display port. You might have a problem with your monitor. Dp has been a good port for gaming for years.

The issue you described is indeed an "issue" with DisplayPort. Although I don't remember how I did it, there is a way you can setup a "virtual" monitor that will act as a real monitor when your real monitor is off. Look into that.

[Glenwing]

Most people don't consider that a catastrophic issue, in fact sometimes this behavior is desired, for example on projectors, TVs, etc... It depends on your setup.

 

If your GPU doesn't have enough HDMI ports then you can just use a cheap adapter ($10 for a passive adapter up to 4K 30 Hz, or $20 for an HDMI 2.0 active adapter for 4K 60 Hz), and it won't disconnect when the monitor is turned off.

I've been hit with this problem before, but I don't consider it a DP problem, but a Windows design problem. I can kinda see where they were coming from, if a display appears not to be connected, then you don't want the system to try drawing there. It shouldn't be difficult to have a user option to override this. The virtual resolution trick kinda works, sometimes, maybe. When I did it, it involved editing registry keys on monitors that have ever been attached to the current GPU.

 

I would also love an override for headless running. It drops down to a low resolution and I have to buy dummy plugs. A hardware workaround for a software deficiency.

[JuJuYuJu]

I've tried all sorts of workarounds before such as the registry tweak, dummy plugs, display fusion,etc and none of them works "properly. I'm using a 10ft Accell 1.2 cable since the startech 10ft I bought first didn't work for 4k60, any suggestions for good cables?

 

Also, hi @sowon!

[manikyath]

this is not a "catastrophic issue", this is a feature that in some cases is actually desirable behavior.

 

also, DP to HDMI adapters are dirt cheap, and dont have this "issue", as it is display sided.

I don't turn off my monitor...

DisplayPort acts like a Plug N Play device, just like a USB drive or keyboard. So switching the monitor off is the equivalent of unplugging it. This isn't really an issue with Windows or DP, it's just how this interface is.

It is a problem if your desktop icons or open windows are not where you put them. The responsibility of managing that is with the OS, therefore it is a Windows problem. I think I've seen this with both Win7 and Win10. The other related problem of running headless was never a problem with Win7, only with Win10 so something changed between them.

My take on why people still like DisplayPort despite this is a two-parter:

1. There are a sufficient number of other advantages that it's worth dealing with
2. Despite the fact that afaik it only happens with DisplayPort, It's not a DisplayPort issue, it's an issue with the implementation by some manufacturers.  Others are free from it.  I have seen a computer unchanged in other ways pick up or shed this issue just by changing displays.

It does sort of result from the design of DisplayPort. With DVI/HDMI, the EDID chip (which identifies the monitor) inside the monitor is actually powered by the source device through the DVI/HDMI cable, so even if the device is off or unplugged, the EDID chip can still be powered and read. DisplayPort also has a power pin, but it isn't used for this purpose, so when the display is powered down, the DP source can no longer see it. There are a few displays that won't behave this way (like my Dell S2417DG), but that's only because they have a setting ("disable power saving mode") which makes it so that when you hit the power button, it doesn't really turn off, it just cuts the display output  so the monitor controller is still active.

I really wish more of them would do it properly like the one you described because everyone I've talked to who has experienced this issue, either irl or on a forum thread like this one, finds it very annoying and stupid that it (sometimes) works the way it does, with forgetting the monitor exists when it sleeps.  Some have said (including you) that there may be legitimate reasons for this.  Perhaps there are.  I can't personally think of any myself, but that's another issue as far as I'm concerned.  When it comes to a desktop monitor, this should never happen imo.

Not sure if my issue is the same as this, but going to quote from this thread.

 

I just upgraded both my video card and primary monitor a few days ago. I'm using a two monitor setup (Dell U2410 and my new Dell S2721DGF), and both are plugged in via Displayport. I had both of my monitors (Dell U2410 & Samsung 24" screen) plugged in via DVI previously (new graphics card has 3 x Displayport and 1 x HDMI). Anyway, when the computer going into power saving mode for the monitors, it seems that each time it happens the Dell U2410 keeps going into power saving mode, waking up, and then going into power saving mode again.

 

I was going to try and buy a new Displayport cable and also thought it might be the video card causing this, but it sounds like I'd be wasting my time trying to change those things? Should I try either of these things out? If not, what would be my best solution? How should I connect the older Dell U2410 24" screen? Should I get a Displayport to HDMI adapter, or Displayport to DVI adapter, or could I get a Displayport to HDMI cable? What would be the cheapest/best solution?

[Daethz]

I don't love it, but HDMI over 60hz is still rare and both my $500 and $800 monitors still need displayport for that reason.

Quite bothered by the constant full monitor disconnection on sleep and stuff issues.

 

What OP talks about is a major issue on LG monitors, it's actually the only issue I have with my $800 ultrawide, but I can live with it..

[Stahlmann]

DP has been working flawlessly for me. And to use my 3440x1440 monitor at 200Hz i need it. HDMI 2.1 was non-existent at the time it was released and DP 1.4 is the only way to get the bandwidth i need for my monitor.
