Windows 10: Monitor not receiving signal from pc after using hdmi passthrough

I have a PC monitor with a single HDMI input. I wanted to have an alternative to having to unplug and replug cables between my pc/xbox knee and my monitor. I first tried using an HDMI switch I had sitting around. This did not work. My next thought was to utilize the xbox HDMI passthrough. This worked, but provided a level of display lag I do not consider acceptable for gaming. At this point I gave up in my quest. The issue is that now my pc will not display to my monitor unless it is through my xbox.

Basically:

PC to xbox = good

Xbox to monitor = good

PC to monitor = bad


Anybody have any idea what might be going on and/or how to fix it

Monitor not working - HDMI has no signal

Yesterday, my ASUS monitor was working fine connected to my HP spectrum using Windows 10. Today, the monitor delivers a no HDMI signal message. I have restarted both laptop and monitor, replaced the HDMI cable, updated display driver and still no luck.
Suggestions welcome.

 

no HDMI signal


I have an ASUS monitor and ASUS desktop with a graphics card not on board graphics. I have an HDMI cable from the monitor to the video card. Today for the first time while on the internet my screen froze and then went blue saying no HDMI signal. I tried everything but still no signal. I then tried my VGA cable and all was working. I then tried my HDMI cable again and it worked until this afternoon when I was watching a video on the internet and the screen froze and said no HDMI signal. also when this happened I could hear my fan running loudly. Any suggestions on what the problem could be?

 

HDMI no signal only during Boot

Hey Guys,

I've just built myself a new computer, all working well, however on boot my HDMI monitor receives no signal until Windows has fully loaded. It would receive signal to see the Bios screen pop up then go blank with no signal and then about 5 seconds later will receive signal and display the desktop.

I've now added a second monitor connected via DVI, even though this is not set as my primary monitor the bios screen displays on it and I can see the entire boot process through this monitor, it will then load to desktop of which a split second later my primary HDMI monitor will then receive signal and start to display.

It's not a massive issue but it's quite annoying, any suggestions?

I'm using a GTX 970 and Windows 8.1 Pro 64-bit.

Cheers,
