Pi 4 blank screen after idle

[benst]

I‘ve just got the pi 4 witht he flirc case and the official USB C power adapter yesterday and installed Raspbian via NOOBS.

Though when the pi is idle for 10-20 minutes the screen goes just blank (connected via hdmi 0 on using 1920x1080@60hz). Sometimes my TV has still a signal and the pucture is just blank, more often though the TV will just say it has no signal.

I haven‘t installed anything else but the updates which were provided after the fresh install.

Any ideas?

Sounds like screen time out, just install the screen saver and then set longer blank times or disable it.

Thanks, I’ll give it a tey. What I forgot to say: I have a RP 3 connected to the same TV which does not show this issue.

Didn‘t work for me.

I‘ve now reinstalled Raspberry, this time using the Raspbian full image and etcher. Nothing else done as yesterday, just installed updates.

So far it works since a few hours, went to black screen and woke up correctly after keyboard input. It never woke up with Raspbian full installed via NOOBS.

Btw, I‘m using a 64GB Sandisk Extreme SD card, formatted as FAT32 previously. With the other image only the boot partition is FAT32. I can only guess this might be related, as I said above it‘s the same OS at the exact same state with nothing done but updates installed and connected to the same network.

See it's little tidbits of information like above that can make all the difference with what answers you receive.
