We have recently purchased “MM400 -V5- VGA 7" TFT - Touchscreen USB - PAL/NTSC - IR Remote” from you. We are trying to integrate it with Marvell’s PXA270 based Windows CE platform. We want to try the native 800x480@70 MHz resolution. We have tried all the timings that were mentioned in this forum, but none of the timings are working fine. The PXA270 processor can only generate pixel clocks of 104MHz, 52MHz, 34.66MHz, 26MHz, 20.8MHz and etc.
Can you please provide us the following timing details?
