Strange screen artifact

Former Member

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

    Hi Roger,

     

    Which models did you see this on?

    The weird thing is that this is done in both OpenElec and XBian. It almost feels like the firmware did not configure something correctly.

     

    I understand that the initial colourful screen is 4 actual pixels exploded by the GPU to fill the screen.

    The 'logo' I see looks like the GPU has then kept those 4 pixels on but at a smaller magnification factor....weird

     

    Cheers,

    Nick

    I'm not "testing pi's if they work as a media center". I'm just "using a pi as a media center". The one I ended up with is the old B (no +). So I have only tested this with one pi, I've seen the square, thought: Hmm. apparently an indication that the GPU is running and forgot about it. It doesn't bother me.

     

    Yes, it looks as if the four pixels are painted and interpolated, for the startup screen blown up to almost fill the screen, while running openelec blown up to say 32x32 pixels or maybe 16x16.

     

    I would think it was put in as a debugging aid to see if the videocore processor is "up and running", it could have been taken out before "shipping" the software, but wasn't. Whether that was intentional or not I don't know.
