Hi, I recently noticed that i had what looked like a dead pixel or two on my 4 month old Acer Predator Helios 300 PH315-51-78NP with a 15.6" Full HD (1920 x 1080) widescreen LED-backlit IPS display (144Hz Refresh Rate, 300nit Brightness & 72% NTSC ) display. It appears to look like two dark dead pixels when on a white screen but still seem to display red. I would like to know if it is a dead pixel, stuck pixel, or something else entirely.

    Looks like stuck pixels to me.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    Is there any way I can fix the stuck pixel if it isn't a dead one.

    Try running jscreenfix(it is on the browser) and move the window with changing colours to where stuck pixel is for several hours. It is very likely that it won't work, but you can always try.

    Poorna1996 never post your model full serial number or SNID (its against the community rules to disclose those publicly) unless asked by an ACER staff member and by PM @Acer-Manny could this be removed :)
