Unable to switch refresh rates in Predator Helios 300

stymrj

Few days back, I got issue in my Acer Predator Helios 300 (2020) due to which I needed to replace my screen. I got to an official Acer service center to get it replaced along with I asked them for thermal pasting as well.

After the screen got replaced, I'm unable to see any option to switch between 60 hz to 144 hz.

You can see there is no option to select 144 hz

And also when I play games, my Nvidia GPU Activity says : "There are no displays connected to this GPU"

I doubt that the engineer might have done some mistakes while connecting the screen or are there some software issues? Please help me. Due to this reason, I'm unable to enjoy 144Hz gaming and when I play games, its stuck on 60 hz and there are visible glitch effects on the screen while playing games. None of these issues existed before the replacement of screen.

If you're unable to switch refresh rates on your Predator Helios 300, try updating your graphics drivers and checking your display settings. Sometimes a restart or adjusting settings in the NVIDIA Control Panel can help resolve the issue.

If your laptop is a Predator Helios 300 2020 model than its a Predator Helios 300 PH315-52, correct? So, the proper 144Hz refresher rate screen for this laptop quoted by Acer are these screens below, as your laptop has the 40pin video connector plug and all these screens will fit and are quited in the PH315-52 Acer service guide.

• AUO B156HAN08.2 (2.8mm) (40pin) (300nits)
• BOE NV156FHM-N4K (2.6mm) (40pin) (300nits)

The N156HMA-GA1 model screen fitted to your laptop by the technician is a 144Hz refresher rate screen but its NOT the Acer PH315-53 fully compatible screen that Acer fits to this laptop so that may be the reason why your screen is not switching to the 144Hz refresher rate! Take the laptop back to the technician that fitted this screen and get him to fit the highlighted screen above that are all 144Hz oen Acer screens for the Predator Helios 300 PH315-52 laptop. as you should be able to change from 60Hz to 144Hz setting in windows > system > display > advanced display settings and that is why the NVidia gpu is also having trouble detecting the screen. Good luck and hope this has helped you out.
