Re: STICKY: HOWTO: Create Custom HDMI modes

I haven't tested it as of yet, but hoping to do so this weekend. Although the additional comments / suggestions have been for an iPad 3/4 screen, not a iPad mini screen, so not sure if it will translate. Will keep you updated!

Re: HOWTO: Create Custom HDMI modes

I've tried with a RPI Zero W set to 256mb as well as a RPI 2b set to 512mb with no luck as of yet.

Re: HOWTO: Create Custom HDMI modes

You need to change your framebuffer from 1536x2048 to 2048x1536 when you want to use it landscape. The timing needs to stay portrait (as per spec). Btw: display_rotate=3 Thanks again for following up @aBUGSworstnightmare. Appreciate it. I have tried changing the framebuffer while leaving the timing...

Re: HOWTO: Create Custom HDMI modes

1.) How do you drive the Display (A/D-board connected via HDMI i.e)? 2.) Timing data taken from page 9 in the data sheet --> why can't you use this Timing? <h_active_pixels> = 1536 <h_sync_polarity> = 0 <h_front_porch> = 12 <h_sync_pulse> = 16 <h_back_porch> = 48 <v_active_lines> = 2048 <v_sync_pol...

Re: config.txt for iPad Mini LCD Screen

So i nearly have it fine tuned for portrait mode. However, when i use display_rotate=1, and swap the framebuffer width and height values, there is black borders on the sides and a fbset -v shows it at 1536x1536. I've tried messing around with the max_framebuffer as well as framebuffer in every combi...

Re: HOWTO: Create Custom HDMI modes

Trying to create a custom timing mode for an apple ipad mini LCD. Not exactly sure how to convert the data from the Timing sheet and EDID parse into a correct hdmi_timings value. Especially for landscape view. Timing Datasheet: http://www.datasheetspdf.com/datasheet/LP079qx.html EDID Parse: HDMI:EDI...

Re: config.txt for LCD Screen

Found this datasheet online for the screen: http://www.datasheetspdf.com/datasheet/LP079qx.html This is working decently well for portrait mode, although there are lines etc still: # For more options and information see # http://rpf.io/configtxtreadme # Some settings may impact device functionality....

Re: config.txt for LCD Screen

Just for clarification, the LCD does show stuff on the display, but the vsync or something is off, as it is scrolling rapidly while flashing intermittently, as well as the resolution is definitely not correct.

Alrighty community. Done enough reading and trying things to make my eyes bleed, and can't for the life of me build the proper setup for my config.txt to show on an LCD I'm trying to drive. The LCD is an iPad mini lcd using http://www.abusemark.com/store/ display controller and Displayport to HDMI c...
