HP Pavilion 15 cs1045tx with Intel UHD 620 screen flickering

[brolight94]

I'm using Pavilion 15 cs1045tx with Intel UHD 620 graphics card and NVIDIA MX 130. When I use the laptop for a while, the screen flickers and splits the view like this. When I choose the other refresh rate, it becomes normal but just for a while then it flickers again. When I reinstall the UHD 620 driver, the same thing happens. I reinstall Windows too but the screen still flickers after updating the driver. When I close the lid and open it again, it becomes normal again then still flickers. I've tried many drivers but nothing worked. Now I don't know what to do with this sisuation. I need help!

This looks to me to potentially be a failing display and not anything to do with the graphics driver. If this is the case, you will either need to have this display (or the whole unit) replaced.

If you really want to play with the drivers, I suggest you go back to the most recent drivers that are being provided by HP. If these drivers have been modified by HP to support the dual-graphics situation, installing later drivers from Intel or NVIDIA will likely result in operational issues (like flickering) or features not working.

Sorry,

Hi,

Thanks for replying.

About your question, I didn't test with an external display. But I'm pretty sure it's because of the UHD 620 Graphics. When I uninstall or disable the driver of UHD 620, my screen becomes normal. The point is it's really hard to use the laptop without graphics driver, I can't adjust the brightness or it's kinda laggy because the refresh rate is not true without driver.

Your laptop vendor probably had customizations in the drivers and you lost them by upgrading the drivers. Go back to those from your vendor. If it then works, you know you need the vendor to provide you with updates.
