Displayport Question

[jimthebob]

Long story short: I have two slightly older Dell (U2410f) monitors and when hooked up to a Displayport on my 1070ti, whenever I shut one monitor off, it detects it as being gone and shifts all my icons, windows, etc to the main monitor. This is annoying as all hell.

What I want to know is what generation/revision of Displayport fixes this issue? I can't imagine this being a desired feature and I'd really like to be able to use just one monitor without having the contents of the other shifted to one monitor when I turn one screen off.

I know this will most likely involve me having to buy new monitors but, well, a guys gotta do what a guys gotta do.

It is working as expected. The problem is really what Windows does.

Since turning off the monitor means Windows detects it as disconnected, Windows thinks it is totally gone and it would be a problem if your windows were on a display that does not exist. So it moves them to the display that is still connected.

If all monitors are turned off, what Windows does is it tends to move its windows to a simulated display which in the past was something like 1024x768 so it would resize everything too. You had to edit registry to make it the same resolution as your actual display resolution so this didn't keep happening. I think MS may have fixed it as I haven't needed the hack anymore.

I don't know if there is any way to tell Windows that the monitor is not in fact disconnected, just sleeping. The best you can do is use something like Displayfusion to apply window position profiles so it will put the windows somewhere convenient and then move them back to the other screen if it is connected again.

Just do what I do, to avoid having to turn off my monitors:

Use solid black background, and turn off "Show Taskbar on all displays"

Now your display goes as black as if it was off whenever you close/minimize your program.

While I will admit that Windows doing nothing on powered-off displays was a nice feature to have, you're only going to get that if you go HDMI. DP was designed to be more intelligent than any previous connection standard, but I'm still not sure why MS decided to use it in this fashion (or not offer a way to turn it off).

That's just it: I don't want to have to use a workaround solution like Displayfusion. I just want my monitors to stay showing up as connected. As a hardware workaround to get my 3rd display hooked up, I've ordered a DP to HDMI cable. Hopefully this will accomplish what I want...hopefully.

Find the Deep Sleep option in the monitor's OSD and disable it.

No such option on my Dell's.

My U2717D’s do this, I actually prefer the auto rearrangment. I use multiple sources on the side displays and when I switch over I don’t want the things I had one one side to be left on a phantom display.

What does bother me is when I switch KVM feeding the main display (which the other two are daisy chained from) to my work compute, Windows thinks I’ve unplugged all of the displays and resizes all of my open windows to something like 640x480.

Annoying for sure. I'm hoping the displayport to vga cable I have on order will eliminate this bug. I just wasn't sure if it was a monitor issue, video card issue, windows issue, or if it's a difference in displayport on the monitor vs video card issue.

It’s a plug and play issue (feature really). Windows adapts to its changing hardware environments. If I unplug my headset, it’ll switch sound to the speakers. Undock my work laptop, it’ll switch the dock’s devices to the internal ones.

The VGA cable may not solve your problem if it detects that there’s nothing to send a signal to and shuts itself off.

The VGA adapter will keep the icons from moving as it won't disconnect when you turn off the screen.
You will probably get a softer image as VGA isn't that great to begin with.
you can go with a DP to DVI or HDMI adapter if your monitor has that either of those inputs.

Back when I ran triples with a DP monitor as the primary, I used an app that would put my monitors to sleep when I put the mouse cursor in the top corner of the screen.
Putting a DP monitor to sleep doesn't disconnect it from Windows so no icons will shift over to the other screens.

Damnit, I was ready to call people out for thinking I ordered a Displayport to VGA cable but then reread my post and, well...it's my derp. I'm a dumbass, I'll own it.

I actually ordered a Displayport to HDMI cable. No freaking idea, ZERO, as to why I typed VGA instead of HDMI.
