Boys,

Im confused. I’ve bought recently a steamdeck Oled 512 Gb, and I need to secure the screen with temper glass. I’ve been looking on internet for good screen protection, and I’m thinking about Spigen Glas.TR EZ Fit screen protector tempered glass. So in that case I would like to ask:
They says that the screen protector is compatible with LCD and OLED version… But how? LCD version got 7" screen when Oled one got 7,4"?

Am I stupid, or I missing something? Theres a universal tempered glass size for both ones?
