Welcome to the Community!
Sorry to hear your having trouble with your picture.
I've run some diagnostics on your equipment and I can see some signal errors that are likely causing the pixilation.
I'd like to send a technician to take a look at this for you. I've sent you a private message (purple envelope at the top right of your screen) so I can get this arranged.
Look forward to hearing from you!
