HP Pavilion Gaming - TG01-1009ns
The brightness of my PC screen fluctuates from brighter to darker every 15 or 20 seconds. 
It's not the screen, I'm sure of this, because connecting a laptop it works correctly. What can be?

OK, to make sure I have this right -- you have connected the same monitor, using the same cable, to a laptop and there are no display issues. Is that correct?

 

If so, that implies that the video chip or card in the desktop is failing.

 

If the desktop has integrated video, with a video chip soldered to the motherboard, that is neither easy or cheap to fix -- as it requires a new motherboard and that will be a USED one, since HP does not sell motherboards (as far as I know).

 

If the desktop uses an add-on video card, then you need to replace the card with one that works.

With the laptop, works ok... may be the video card

Thanks
