Brand new and working NVidia GTX 1080 display on MOBO HDMI port!

[lottalava]

Hello folks, I came with a very strange problem, i´ve just installed my windows 10 and all my games. After i installed Ubuntu 17.04, all fine.

 

I tried some of the games on windows to check the graphics card is OK, all fine.

 

I went to lunch and after I turned on the machine and all display from NVidia is going to MOBO, I mean, all graphics from the GTX 1080  is been output in MOBO HDMI port, i tested some of the games and everything is working, but i now connected through MOBO HDMI.

 

When i connected my monitor cable in the GTX 1080 no vga display, only a black screeen.

 

Some idea?

If you have a GPU installed the motherboard won't output anything (usually).

Try reading the post again.

His GPU is not outputting anything, his motherboard is.

You have it backwards.

Sure, thats what the normal behavior, but now i watching with my monitor connected in the MOBO, what could change? 

 

I can say, the GTX 1080 is working and a can see when i open a game, like Dirt Rally for example.

I should probably actually go to sleep. It's after midnight and I have to get up at 4:45.

Mobo output is most likely IGPU powered.
Default behaviour of most motherboards is to switch off internal gpu when an discrete card is present (although can be turned back on).

 

Try shutting down, removing gpu, start back up, remove all video drivers, reseating gpu and then cable to directly to GPU.

Try switching power cables, if you have dual bios GPU, try flicking the bios switch (on the GPU) if you have it.

 

Try poking in UEFI, maybe reset bios (Clear CMOS), and reconfigure drives and try again fresh.

How can you tell that the gpu is doing the graphics processing?

Why would you decide to plug your monitor in to your motherboard..?

Cause Assetto Corsa cant work at 300 fps with the GTX 1080 and 5 fps  on onboard graphics card!

It was just a guess, i thought if the QCode was A0 them my machine booted normally, so i tried the MOBO´s HDMI port.

I was wrong, the MOBO was sending the video, for some reason i dont known yeat the MOBO recused to read PCIEX2 ( i put to 1080 there ´cause to get far from the water cooler ), i changed to PCIEX1 and everything is fine.
