I bought this module and could never find what is the resolution. There is place show WVGA that means 800*480 or 854*480. I also saw WQVGA and I assume it means 480*272 or xxx.
Does anyone know its resolution?
Thanks,
Chu

Hi Chu,
The resolution of MCIMX28LCD is 800x480.
root@freescale ~$ fbset
mode "800x480-92"
# D: 50.000 MHz, H: 50.403 kHz, V: 92.314 Hz
geometry 800 480 800 480 32

Hi Chu
Yes this is correct (as mentioned in RM and linux sources),
that the i.MX28 is able to drive LCD panel up to 800x480
resolution at 60Hz. Since both pixel pipeline and LCDIF do not impose any hard
maximum limit to 800x480, in general higher resolution LCD panel is allowed.
However, we do not recommend driving any panel with higher resolution than
800x480 due to limited internal bus bandwidth. In theory it is possible to run at a
higher resolution at lower frame rate (800x600 @ 48Hz is the same number of
pixels/sec as 800x480 @ 60Hz).
Best regards
