Windows 10: Boot Issue with 2 monitors: I Just upgraded my GPU

I have a custom PC running windows 10:


MOBO: ASUS TUF gaming X570 Plus

CPU: AMD Ryzen 7 3700X

RAM: Corsair Vengeance RGB Pro 16GB 2x8GB DDR4 3600 PC4-28800

GPU: ASUS ROG-STRIX-RX5700XT-O8G-GAMING


When I boot with one monitor connected, I have no issue. When I boot with 2 connected on try to connect two when the PC is on, my resolution on original monitor HDMI 1080p gets reduced to 1280 x 1024, the other monitor appears to be connected in display settings, but does not display anything. And I get massive input lag and my PC is unusable until I unplug the second monitor DP 1080p 144hz.


Extra details:

• I have resinstalled GPU drivers, I have checked my MOBO driver tool and the rest of my drivers are up to date including BIOS. I have rebooted several times:
• The first time I booted yesterday with 2 monitors, I had no issues and Played a game while streaming twitch on my second monitor for 6+ hours with no issues Yesterday, so I am confused about what brought about this issue, started when I tried to wake my PC from sleep after this 6 hour session last night.

PS: I may have an issue with the seating of my GPU into my MOBO, because the clip that holds this new GPU is stuck I cannot release it by pressing it with a screwdriver. If this could be a seating issue, I will, mess with this clip until I can force my card out and try my second PCIE 4.0 slot.


Thank you in advance.

Computer won't boot with 2 monitors connected

I've been having this problem for about a year now. When I built my PC, I only had one monitor and everything ran smoothly and fine but as soon as I added a second monitor there is a 50/50 chance that my PC will boot up with two monitors connected.

When I turn my PC on it will turn on but nothing will display on both monitors and I get a white Light (CPU) error code on my Asus mobo (strix 270-e). If I want to start my PC with two monitors I have to unplug one monitor, boot up, then plug in the second
monitor and everything is fine. I use DP to DP and HDMI to HDMI so I know its not the cables.

Also, I originally had a GTX 1050ti and when I upgraded to two monitors the problem started happening. I assumed it was the GPU so I waited and then bought a GTX 1070ti a while later. Same problem is still happening so I know its not the GPU. I also tried moving
the GPUs to different slots in the mobo and same problem so the slots are fine as well.

I have tried Uninstalling and reinstalling windows and reverting to default on my BIOS settings and nothing happens. I have also tried configuring multi displays in the BIOS and that didn't do anything either.

Any suggestions? Thanks for the help in advance.

 

Computer won't boot with 2 monitors connected

Hello. Recently I have changed my GPU to Sapphire RX 570. I have two old monitors with VGA connections. Previously I used to plug my second monitor to motherboard and my main monitor through HDMI-VGA adapter to my GPU. Since my new GPU have 2 HDMI connections
and im usually watching something while gaming on my second monitor I wanted to reduce load on my CPU and bought new HDMI - VGA adapter. Its a bit different than my other one. Once I connected second monitor through adapter I was able to see that two monitors
were working on extended mode quite good but it only lasted for around 1 min. After that both monitors went off and were displaying no signal. It went on bootloop. I could see through both monitors while it was loading through bios and even while windows
were connecting to user account. But once spinner with account name were almost finished boot loop started again with both monitors showing no signal once again. Basically I cannot boot my PC to Windows when both monitors are connected to two HDMI slots in
my GPU.

Things I have tested:

Run both monitors separately for a few hours only on new HDMI - VGA adapter. Both monitors worked fine

Reset BIOS settings to factory defaults

Boot into safe mode then connect second monitor

Remove and reinstall video card drivers

Reinstall windows

Change HDMI adapter slots / change monitor slots

Update Windows

Take out GPU and reseat it again

Restarting multiple times
