I have this issue when the gpu isn't showing any output. Says no signal on the monitor, pc boots up normally . Tried every major solutions none worked. Changed the psu, used DDU no difference. After installing the drivers everything runs okay but the problem arises when i manually shut down the pc and boot it up again after some time, shows no signal on the monitor
Specs :
i5 6400
Gtx 1060 3gb oc
Corsair vengeance 8gb
Corsair vs450

(I'm fairly new to the site and sorry for the bad English)

I assume you're running Windows, which version?

What other software do you have installed?

Would it be safe to say that this problem doesn't occur when the computer has warmed up sufficiently?

It's running windows 10, and some stock applications like gpu tweak etc. Could it be any driver issue?

I would get rid of any programs that want to mess with your graphics card at all. Once you've got the card working properly for a few days, then reinstate them (one by one if you want to play it safe).

Personally I think this might be hardware related hence my last question, but it makes sense to rule out software first.

You have a iGPU.

Leave the graphics card in the computer, enable the iGPU. Plug your monitor into the iGPU and boot the computer.

Check in windows if device manager sees your graphics card. If it does, try plugging your monitor into the various ports on the graphics card.


Your issue sounds like a bad cable or bad port. Most likely bad cable.

Check the simple things.

The other day when I installed my new GPU I forgot to plug in the 8 pin power cable to the GPU so I had no signal.

Once I plugged the HDMI cable into the motherboard hdmi instead of the GPU.

It also sounds like you may have a bad cable or bad port in the monitor or GPU like Leeea and Furious_Styles mentioned.

I hope it isn't any hardware related. It would be very helpful if you tell me which programs I should remove

Already checked those many times, my motherboard only have a vga output. If it was an issue with the cables or ports could the display go black after installing drivers?

Yes.

Installing the drivers may enable higher color depth formats, HDR, high refresh rate, gsync, etc. These features require more data to be sent down the cable.

If this is the case, starting the computer in safe mode may let you disable the feature causing your issue. You may also be able to disable HDR / Gsync on your monitor.


ex: I had a cable that could do 4k60Hz non-HDR (8-bit per pixel), but when asked to do 4k60Hz HDR (10 bit per pixel) it just showed a black screen.

I presume this bit (in bold) means that the display comes on at the correct resolution after installing the drivers? How about if you restart the computer, is it still working as it should be then? Then only after you shut down the computer, it shows no signal?
