Strange screen artifact

Former Member
Former Member over 10 years ago

Hi,

I have 3 Pies

#1  1x Model B with 2 USB ports

#2  1x Model B+ with 4 USB ports

#4  1x Pi2  (there is only one model, right?)

 

I have used all 3 to run Openelec.

#1 works perfectly

#2 and #3 also run openelec but they both show an artifact on the top right-hand corner. It seems to be a miniature version of the colour screen that is shown right after the Pi wakes up but before it runs an OS.

 

Has anyone else seen this????

 

Cheers,

Nick

    It's a low-power warning. It shows up when the 5V supply goes below 4.65 if I remember correctly.
