I’ve got no problems with my DT screen , never had an issue with the original game boy screen either. Considering it’s a new oled screen I’m a little surprised of the ghosting / imperfections.
I appreciate economies of scale may impact their screen decision , I’ve never had any lcd / screen device with such an issue that I can remember, eg many phones , cameras , maschine , lxr , iPods etc.
The worst I’ve had was possibly a dead pixel on psp
It is possible that any machine can have a fault , my sh01a needs to be replaced … i’m Always cautious when issues are flagged as the internet can amplify any potential issue / misunderstanding / design decision.
I’d expect new elektron boxes use the same screen , buttons , encoders , and the issues above are familiar DT ‘things’
