Windows 10: Monitors lose signal with dedicated GPU but fine with iGPU

Hello! Several months ago I started losing signal on my two monitors intermittently, requiring me to hold the power button until the system went off. When I powered it back on they would work fine. It was usually weeks between having to do this so I didn't think much of it, but recently it's happening more and more often. Sometimes the fans go crazy and sometimes it will reboot by itself but neither one happens every time. This usually happens when gaming, but not always.If I plug the monitors directly into the motherboard and unplug power from the GPU, everything is stable and works fine.Some

Gaming Laptop uses dedicated GPU on a non-existent monitor

So I have a bit of a complicated problem. Up until recently, I've been doing good with my Laptop. It has an igpu and a dedicated gpu. I had 2 monitors, the one directly connected to my laptop was run by the igpu, and the external was run by the dedicated
gpu. I am on vacation, and don't have access to my second monitor, and now, when I try to run a game with my dedicated graphics card, it will try to pull up the game, but close it, since the dedicated gpu is set to my second monitor. How do I change this?
My Geforce Experience app isn't working by the way.

 

Games and applications are using iGPU instead of Dedicated GPU

Helloo, I have been facing this issue from 2 weeks now, I usually run games and editing software with Dedicated GPU (Nvidia)

Brand-> Laptop - HP

Model-> cx0140tx

But now even if I force an application to use this gpu it works on Integrated GPU (Intel® UHD Graphics 630). I dont know if GPU is giving output on low power, but PhysX Indicator never shows on apps if its turned on, tried reinstalling graphics driver, updating
iGPU Driver, forcing apps to use it, nothing worked. Please help

 

GTX 1050 ti Monitors Lose Signal

So far there's been a catalogue of symptoms, and the worrying thing is there are literally pages and pages of the same issue with GTX 1050's on the GeForce forums.

Symptoms so far:

• After getting to the logon screen, both my 4K monitor (plugged in via DP) and my 1080p monitor (plugged in via HDMI) spuriously lose signal for ~5 seconds then come back. This happens constantly with no apparent timing.

• Whenever I open a game launcher (not a game), or Google Chrome, the screen flickers again, only this time I get a Windows 10 event alert saying "application has been blocked from accessing graphics hardware".

• When I check event viewer System logs, the yellow triangle simply says "nvlddmkm stopped responding" in each case of the monitors losing signal.

Attempted fixes from numerous threads:

• Installed the latest Game Ready "stable" drivers, installed latest "beta" drivers, and also installed some random "stable" drivers from a month ago. Uninstalled previous drivers with DDU each time and restarted before and after installation. Issue seems to persist sporadically.
• Turned PCI Power Management off in Windows Power Settings. No change.
• Switched Power settings in NVidia Control Panel to Maximum Performance. No change.
• Gone into the registry and added a QWord(64bit) to CurrentControlSet001/Graphics/Drivers called "TdrDelay" and set it to 8 (also tried 10). No change.
• Tried unplugging the secondary monitor. Managed to play Warframe for an entire evening without a monitor signal loss.
• Switched secondary monitor to DVI Single Link cable to 1050 ti, and also tried secondary monitor on iGPU with primary monitor on 1050 ti. Still get signal losses on main monitor, secondary monitor does the same but is delayed (WTF?).
• Downclocked GPU 50Mhz. No change.
• Increased Power Limit by 5%. No change.

Fixes I still need to try:

• Try a different DP cable in main monitor/try HDMI cable instead.
  
• I get the signal loss when I open Chrome, going to turn off hardware acceleration as that apparently solves things
• Use a DWord(32bit) registry key instead of QWord for TdrDelay
• Going to try the 375.50 drivers, as they're allegedly old but stable for low power Pascal GPUs.
• Resetting CMOS for whatever reasons - some random guy said this solved his issues.

Fairly convinced it's not a hardware issue since there are so many people with the same issue as me. One slight glimmer of explanation is that Micron memory may be at fault, I need to check if its Samsung or Micron stuff on mine. Apparently there were some GTX 1070 stability issues with Micron VRAM that were fixed with an update.

My entire system has been stable for years, sporting a R9 295x2 up until 6 months ago with no stability problems. Doubt it's PSU related. Motherboard is also on the latest 2.50 BIOS.

Help me TPU, you're my only hope.
