Hello everybody! I bought a motherboard Intel DN2800MT and IPS flat-panel CLAA070WP03 XG. Wired according to datasheet. BIOS set up. I get the picture from the matrix at 1280 * 800 with the rotation of 90 degrees. In the BIOS settings, there is support for this resolution, but the picture is similar to the resolution of 800 * 1280 instead of 1280 * 800. In the settings you select the resolution for LVDS have items with the inscription "Reserved". How to add the resolution 800x1280?
Thanks for the pictures. Based on the information, since the panel does not EDID information, seems that is not reading 1280*800.
I would recommend testing with an earlier BIOS version:

What does the screen look like when selecting different screen resolution?
Yes. I lowered the BIOS to version 0165. The result was the same.
Intel engineers! Please add a string 6 resolution 800x1280.
Red marked do not use without consulting Intel. Give me consultation!
