ipad 3/4 screen with controller board for raspberry pi
« on: May 10, 2017, 06:56:53 pm »
im looking for a 1080p IPS screen for my bartop im making. the smallest i can find is 11.6 inch. which is just too big by about 1cm! for the bartop im making. sucks... so im thinking

ive seen people use replacement ipad 2 screens (1024 x 768)
with a 3rd party hdmi controller board with RPis which the Pi can handle. but i really want that FHD res.

has anyone used an Ipad 3 or 4 (2048 x 1536) replacement screen on a Pi.. can you use 1920x1080 on it even if its letterboxed?

I haven't seen it. Doesn't mean by a long shot that it hasn't been done.

Looks like you could easily get 1920x1080 out of the pi, but not much more
hdmi_group=2   # DMT
hdmi_mode=82  #(1920x1080 @60Hz)

There's a note:

Quote
Note that there is a pixel clock limit.The highest supported mode is 1920x1200 at 60Hz with reduced blanking.

You might try searching the boards referenced in that note about the pixel clock limit. See if anyone has done this. I would be surprised if there wasn't an answer out there already.
