Computer doesn't detect my Monitor.

Oke so I am having kind of a weird problem and I think the fix should be fairly simple.

So I have a gaming PC and an Acer G246HYL monitor. These 2 worked perfectly fine together up until the point that I changed my GTX980Ti for a GTX1080Ti a few months ago.

Now whenever I first power my PC and afterwards power my monitor, the monitor won't receive a signal from the GPU. This happens 10/10 times, while if I first power my monitor and then power my PC it always works 10/10 times....

The only thing I can think of is that there is a setting somewhere the tells the GPU the only check for new screen inputs on bootup and not when it is "live".

My GTX980TI and 1080TI both were connected with the same DVI cable, and the screen is still the same. Also all other PC components/OS (windows 10) are still the same.

Is anyone familiar with this kind of a problem? I mean it's not game breaking I kind of learned to power the monitor before the PC but it just annoys me, mainly because I can't seem to figure out what is causing it.

Hi @nyldra ,

Try installing the latest graphics adapter drivers appropriate to your OS (Win 10 32-bit or 64-bit you didn't say) to see if it makes a difference.

Download them from the video card maker's website,

If you have done this already, apologies.

Thanks for the reply, I am using 64-bit windows 10 which is fully updated (Version 1803, build 17134.48) and my graphics-card driver is updated (version 398.11, release date 5 June 2018).

Since I am having this issue ever since the switch to 1080TI about a year ago I've gone trough many OS/GPU driver updates which never changed a thing so I doubt it's driver related.

Thanks for the input tho it's appreciated!

Hi @nyldra ,

Have you tried using a HDMI cable instead of a DVI cable?

Also just wondering if it has something to do with HDCP which the new card may be looking for and which your monitor hasn't got (at least I don't think it has).

@jayeff

My I went ahead and checked the Nvidea control panel and it says my GPU and screen are HDCP ready.

As for a HDMI cable I haven't tried yet (tho it used to work with my 980Ti + DVI), but I'll see if I can find a HDMI cable right now and try

@jayeff Alright scratch that idea XD This screen only has a VGA and DVI port and my GPU doesn't have a VGA port so yea.... can't test that sadly.
