Bounty: 50

I’ve never used the always on visible workspace feature without the dual monitor setup, so it’s not clear to me whether that part is related.

When I pin a firefox window to every workspace on one monitor and then use other applications on the other monitor, then click back on the pinned firefox window, it has a nasty tendency to minimize. Since that isn’t the only firefox window I have open, I can’t get it to return by simply clicking on the firefox icon on my system tray – I have to close every other firefox window and then click on the icon. Even then it initially goes to whatever application I had been working on before I clicked on the firefox window.

I have no idea what could be causing this bizarre behavior, and my efforts to google haven’t really turned up anything helpful unfortunately.

My Ubuntu version 16.04:

#StackBounty: #windows-10 #multiple-monitors #hdmi #projector #hdcp PC to projector HDMI handshake issue

Bounty: 100

I think I have a HDMI/HDCP handshake issue with my projector. I have had an Optoma EW628 projector hooked up to my desktop PC for about 2 years which has always worked perfectly.

I’m running Windows 10, and the graphics card is an admittedly old Intel HD Graphics 2000. I have an HDMI lead plugged into the HDMI port on the PC with the other end plugged into the projector via an HDMI to DVI convertor, as it does not have an HDMI port.

As I say, this set up has worked fine for around 2 years until this week, when I had Sky Q installed. For those that aren’t familiar, Sky Q is a digital TV home network that has a master box connected to a satellite dish, which then uses home Wifi network to stream content to connected mini boxes in other rooms around the home.

I used a HDMI splitter to connect the sky box to the projector as well as the PC, and this seemed to work fine for a short time. I could switch between the two signals without issue by pressing the switch on the splitter.

However, all of a sudden the PC is unable to detect the projector.

Things I have checked:

I have removed the splitter completely and

  1. Connected the projector directly to PC: no signal on projector

  2. Connected the projector directly to Sky box: signal comes through fine

  3. Connected another HD monitor to PC via same HDMI cable: signal comes through fine

  4. Connected another laptop (with Intel HD Graphics 5300 card) via HDMI cable directly to projector: no signal on projector

  5. Connected another laptop (with Intel HD Graphics 5300 card) via same HDMI cable directly to another HD monitor: signal comes through fine

  6. Connected another PS3 via HDMI cable directly to projector: no signal on projector

  7. Connected another PS3 via HDMI cable directly to HD TV: signal comes through fine

So it seems that the projector will now only recognise the signal from the Sky Q mini box and nothing else.

I have tried the usual process of connecting a projector to Windows as described here to no avail.

I have also come across a few posts describing similar issues here, here and here and what I have surmised from those is that connecting the Sky Q mini box has caused some kind of HDMI/HDCP handshake issue that has encrypted the connection and only the sky Q connection can bypass it.

Does that sound feasible? If so, is there a way round it? It seems that the issue is with the projector, so is there a way to do a firmware upgrade? Or get in to the engineer menu and do a factory reset or something?

Or could it be that something is fried in the projector now? and if that means I need to go out and buy a new one, what are the chances of this happening again?

This is completely frustrating as it ran without issue for so long and is still happy to display the Sky Q signal.

#StackBounty: #windows-10 #multiple-monitors #kvm-switch Startech DP KVM Switch, WIN10, GTX1070 issues; SV211DPUA

Bounty: 50

SV211DPUA (https://www.startech.com/Server-Management/KVM-Switches/2-Port-DisplayPort-KVM-Switch~SV211DPUA)

I followed the startup instructions here exactly: https://www.startech.com/faq/kvm-switches-setup

and Also the troubleshooting here: https://www.startech.com/faq/kvm_switches_general#SV211DPUA – by switching KVM and External cables, and performing the startup all over again, for example.

On my DESKTOP PC, which has a GTX 1070 with the latest drivers, and Windows 10 fully updated including the creator’s update, this KVM switch always has issues which I will describe in more detail below. The Desktop PC has 2 HDMI-connected monitors which are NOT going through any KVM. They are always on. The KVM controls only one monitor via display port.

On my Suface Pro 4, it works every time (the 2nd PC connected to the KVM).

When I first turn on my Desktop PC, the KVM works fine. Then I switch to my surface, still works fine. Finally, I go back to my DESKTOP PC, and the HDMI-Connected screen (no KVM) begins to flicker on and off a few seconds at a time. The DP connected screen (through KVM) stays completely black, but the monitor light is blue (meaning it’s not in idle). If I disconnect the DP cable from the DESKTOP PC, or turn the kvm-connected monitor OFF, the DESKTOP PC loads the 2nd HDMI-connected monitor without issue.

At this moment I have disconnected the display port cable from KVM-to-Desktop, but am still using the KVM to switch my controls (both mouse and keyboard) and use my other 2 remaining monitors on the desktop PC successfully.

I opened a chat w/ Startech, and they were actually quite helpful. Below are the further tests performed:

Test 1

  • Please connect the DP monitor directly into your Desktop as a third monitor (not passing through our KVM).
  • ok completed. Monitor is up. So right now, I have all 3 monitors working just fine. And I can move between my SP4 and Desktop using the KVM for controls only, works great actually.
  • Now I simulated the KVM’s display switch by disconnecting the DP cable from your desktop, waiting about 20 seconds, and then reconnecting it.
  • The monitor came back instantly when i plugged it in again after ~20 sec.

Test 2

  • Started on the Desktop. Only the Displayport monitor was connected to the desktop at this time (disconnected the other 2 HDMI directly-connected monitors). DP was connected THROUGH the KVM. No issues here yet.
  • After I switched to the SP4, it worked fine on the surface too.
  • Then I switched bakc to the desktop, and I saw nothing on the screen (no connection basically, but it did seem like it was flashing a little bit, trying to do something).
  • After a minute of that, I tried to disconnect the KVM, and connect ANY of the monitors directly again to my desktop PC, but none of them connected. HDMI or DP, didn’t matter.
  • Then I thought maybe it was due to mouse/keyboard being non responsive, so I connected them directly via usb to the desktop. They wouldn’t even get powered.
    No red light on mouse, no caps lock on keyboard.
  • So I had to shut the PC down manually, restart, and everything came back.

However, they conclude that it’s not hardware related to the KVM as the switch is very simple (see below).

It is nothing more than a hardware switch. Although the USB
connectivity can be more complex depending on the models, the actual
display switching has no chipset or particular technology other than a
physical cable switch. There is no software, drivers or associated
technology that could be involved either. Furthermore, we also know
that your KVM isn’t defective since it works on other computers. The
absolute only difference from our KVM’s usage and an actual manual
cable disconnection is the fact that the KVM keeps the cable’s
connection alive. When switching, the computer loses the monitor’s
information (identification information), but remains aware that a
hardware connectivity is there. This, normally, doesn’t cause any
issue on the computer’s side other than resolution changes and monitor
re-arranging.

So finally, I’m asking about what on my software or hardware side on my Desktop PC could cause this issue and if anyone has more items to try or look into to fix it.

Thank you!

Online I find that there used to be a sticky edges toggle in the Displays settings window, but I can’t find it there.

Was the feature dropped? Was the toggle moved?

#StackBounty: #windows-10 #multiple-monitors #resolution #dpi #scaling How to change screen's DPI scaling automatically when switch…

Bounty: 50

I have a 14″ 1920×1080 laptop and a 24″ 1920×1200 screen. The pixel density difference is huge.

When I’m using the large screen as a main one and laptop as an additional screen, I’d like to have the smaller one set to 150% scaling so that I can use it comfortably. But when I’m away from my desk and the external screen is disconnected, I’d like the laptop to automatically switch to 100% scaling to maximize desktop area.

How can I make Windows switch DPI scaling automatically when external screens are connected or disconnected?

I’m okay with using 3rd party software if it’s necessary, but I’d rather stick to built-in features of Windows.

I’m using Windows 10 Pro Version 1703.
