No dead pixels, no sub pixel weird colorations, just a totally fine normal Steam Deck with a fun color way. If you’re an owner of the LE waiting for it to arrive, freaking out about it because you’re seeing all the issues here, fear not there is a good chance your Deck is going to be fine.
You will notice dead pixels, here’s how:
You can open up Firefox (when you hold down power button, go to Desktop, then click Firefox it’ll download after a minute) search ‘dead pixel test’, and click onto it. If there is a dot on the screen that doesn’t come off when you gently use the microfiber cloth (aka check that it isn’t dirt), you will want to go through each screen color.
If a black dot only appears on one of the three colors, which are Red, Green, Blue, it will also show on White, then you have a dead pixel (subpixel, whatever color it shows black on is what type of dead one it is; i.e. black dot on green, nothing on blue or red means you have a dead green subpixel).
OLED displays work by using a red, blue, green subpixel to display colors. White is a mix of all three, black is the absence of them. So on white if green is out you’ll have a reddish brown or purple dot form, on red you’ll have no dot, on blue no dot, but on green there’ll be a dot.
