7 Inch LCD screen problem

vbolshakov · Published in 2017-11-8 22:24:53

I ordered 7 inch LCD screen and unable to find native screen resolution so console text will be without scaling artifacts in the middle of screen.
It is not good both in 1024x768 and "native" 1024x600.
Do anyone able to find native screen resolution or LCD controller CON3 pinout?

1. Plz check the HDMI cable

2. Plz make sure the power supply to the transfer board have reached 5V 2A

3. Plz re-connect the LCD screen and the transfer board

Already checked and tried several times.

Can you provide physical LCD screen resolution? Is it real 1024x600? Can you provide config for fbset? Can you provide CON3 pinout? Is it possible to reconfigure LCD controller using UART?

What about CON3 Pinout? is it possible to connect to LCD controller and check params?

Or, may be can provide full timing values like
--timings, -t ...
set  all  timing  parameters at once in the
order  <pixclock>  <left>  <right>  <upper>
<lower>  <hslen> <vslen>, e.g.  -t 35242 64
96 35 12 112 2

Can you upload screen image (photo, not screenshot) with text on it? Not just desktop with solid background color.
