I checked the product specifications and this system is using the NVIDIA* GeForce * graphics card as the main video source, so you need to check that you have the driver for this device. I would also suggest that you check in the BIOS to see if you have hybrid graphics and to use this option to switch to the integrated graphics, see if the screen behaves in the same manner.
thanks a lot for reply!
I have updated both drivers, NVIDIA GeForce (update required) and Intel HD Graphics Family (no update available), few days ago. Nothing have changed my screen flickering.
I will try to check BIOS, but it's strange.. Screen's troubles began after a windows update (we suppose), in the same time with my co-worker's screen.
Yesterday I've installed Microsoft Office 365 (and nothing changed), today my external monitor (the only one that I've left active) flickers quite never. Magic?!
I'm afraid to try to activate the notebook monitor... it's all too strange...random.. :-S
According to the information provided it seems that the actual laptop monitor may be faulty because if you don't see any flickering issues with an external monitor is because the drivers are working fine. In some cases a flickering issue could be related to a physical problem so you may also contact ASUS and request some troubleshooting and, if possible and applicable, a replacement.
If you have more questions please let me know.
