Windows 10: Multi-Monitor User: BIOS Always Displays on the Secondary Screen at Startup

For Multi-Monitor Users: BIOS Always Displays on the Secondary Screen at StartupAs a multi-monitor user, every time I press Win + P and select "PC screen only," the display does not switch to the primary monitor as intended. Instead, it defaults to the second screen. Where I have designated screen 2 as the primary monitor. I believe this is a logical bug.Although I managed to resolve the issue by swapping the DP DisplayPort Cable connections of screen 1 and screen 2, I am seeking a more fundamental solution that doesn't require physical manipulation—perhaps by modifying the registry. However,

Blurry text on secondary monitor in multi-resolution, multi-DPI setup


This is probably the most painful issue I have with Windows 10 right now (and likely previous versions as well, but I didn't have a multi-monitor setup back then).

The monitors I have are as follows:

1. 3840x2160 (4K UHD) monitor with preferred DPI: 144 (150%)
2. 1920x1080 (Full HD) monitor with preferred DPI: 96 (100%)

Whenever one of these monitors are set as primary, all desktop applications displayed on the secondary monitor (doesn't matter which) has blurry text. Exceptions are the Windows Store Apps like Windows Store and Microsoft Edge, along with the Taskbar/Start Menu, the Taskbar/Start Menu settings screen, the Taskbar context menu, and the desktop context menu which passes the DPI test with flying colours, with crispy text on both monitors (occasionally a DPI switch bug gets in, but I can mostly ignore that). The problem is, as you can probably guess, is that >99% of the applications I use aren't Windows Store Apps.

Here are some screenshots. The "Taskbar and Start Menu Properties" text is what the text should look like while the Visual Studio 2015 text is an example of the text most desktop apps get. The blurry image is what happens when the UHD monitor is not the primary monitor.

Note: Both of these screenshots came from the 150% DPI monitor so it's best viewed at that (144) DPI level. The 96 DPI monitor is similarly affected.

Things I've already tried:

• Reinstall the graphics driver (this was unhelpfully given by a Microsoft Support Engineer). Did this multiple times in fact for unrelated reasons.
• Reinstall Windows 10 (through Reset This PC recovery option). I did this for also unrelated reasons but it definitely doesn't fix this issue.
• Use the XP Explorer "fix". Merely worsens the problem.
• Adjusting ClearType options. Alleviates the issue a bit but see next point.
• Disabling ClearType on the affected monitor. The text obviously sharpens, but it's painful to read and a close inspection of the text reveals the issue isn't solved at all, only mitigated slightly.
• Replacing the video card. I swapped this in with my older GTX 560 Ti but it's obvious the problem remains. Both it and my current card are NVIDIAs though, so it's vaguely possible the drivers or the cards themselves are the cause. I don't have an ATI/AMD card (that still works, at least) to test the setup and every Intel iGPU I have either has only one monitor output or is incapable of handling UHD resolutions.

Things I won't try:

• Setting both monitors' DPI to 96. Text would become microscopic considering the UHD monitor's actual size.
• Use the text resizing feature instead. I'm going take a wild guess that this is not monitor-specific and would cause everything on the HD monitor to be far too large to the point that I'd rather unplug it.

Does anyone have a multi-resolution, multi-DPI, multi-monitor setup with or without this issue? The text is painful to read on whichever is the secondary monitor right now, and is extremely apparent whenever the background is dark.

 

Secondary monitor suddenly not recognized

Hi there,

My setup:

Intel i7-3770 @ 3.40 GHz

EVGA Nvidia GeForce GTX 1060 6GB

Win 10 pro 64 bit

My graphics card has the following outputs: 3x Display port, 1x DVI, 1x HDMI

Until now i had my main (4k) monitor connected via display port and a secondary monitor (FullHD) connected via DVI. It was working fine for over a year. Two days ago during gaming my secondary monitor
suddenly shut off. Since then it isnt recognized anymore.

Troubleshooting until now:

• any other monitors i plug in via hdmi or dvi arent recognized in windows (device manager or display settings) or nvidia system control (i dont have other display port monitors available)
• also the manual device recognition in display settings and nvidia system control doesnt find anything (same with searching for new hardware in win device manager)
  
• when starting the pc with only the DVI plugged in, BIOS and windows loading screen is displayed via DVI, as soon as the login screen would come up, DVI screen shuts down and nothing is displayed (when
  plugging in dp at this point, win login screen is displayed there)
• cables are working fine (hdmi cable works with other pc, dvi screen displays bios when no other screen is plugged in)
  
• i selected dvi as source on the secondary monitor
  
• when plugging into the pc the secondary monitor it lights up and tells me "no signal available"
  
• everything behaves the same regardless of which of my three display ports i am using
  
• i rolled back to different nvidia drivers and clean installed the newest driver, nothing changed anything
  
• i installed all available windows 10 updates and drivers
  
• i reset windows
  
• i disconnected power from all screens and waited vor 30 mins
  
• i deinstalled the monitor and graphics card in device manager
  
• i removed, cleaned and reinstalled the graphics card from my motherboard
• i tried to connect the secondary monitor either via DVI or HDMI, same behavior in both situations
• i tried to connect another monitor either via DVI or HDMI, didnt work either

i dont know what else to try... thanks in advance for your help.

 

1 monitor primary display and 4 monitor secondary display

Our church wants to setup a display composed of four 20" square monitor. This will be our secondary display.

Computer specs at the moment:
CPU: Intel i3-3210
GPU: NVIDIA GeForce 210
RAM: 2 x 4GB DDR3 1333 MHz
MB: ASUS P8H61-M LX3 PLUS R2.0
OS: Windows 10 Pro x64

Is it possible to add another gpu for secondary display and then use a multi-monitor display adapter for 4 monitors? If so, what kind of gpu would we need?

Thanks...

PS: As much as possible we would not like to change our MB. But I've included it just in case.
