postexitus I have seen on some machines (I think another Lelit machine) a moving square on the displays, which are of course OLEDS.
I don’t remember any screen saver on the Lelit Elizabeth and I didn’t think screen burn would be a problem if I am honest. I shall discuss with Lelit for a potential programming change across the range of machines/grinders that don’t have this.
I think the Bianca V3 has a moving square that appears on a black LCC display screen, when the machine is left idle for a while that may well act as a screen saver. It’s certainly an alert that the machine is on. I am using another machine where the screen simply goes black, which is unuseful!
I can’t remember 100% because of so many machines and I have my Puristika on the counter for the moment testing other equipment.
I’ve let Lelit know as I am pretty sure it was Bianca, but it’s something perhaps they can look to implement across the range. It would of course require the different LCCs to have new programming written by Gicar.
