Forum Post: what is the max resolution supported by dm8168 vpss?

I want to have 800x2560 resolution output on dvo2 of dm8168evm. I have modified kernel image to support the customized resolution, and I do have the output timing(pixel clock, hsync, vsync..) as I set, like the following..

root@dm816x-evm:~# cat /sys/devices/platform/vpss/display1/mode

800x2560@60

root@dm816x-evm:~# cat /sys/devices/platform/vpss/display1/timings

164102,800/40/88/128,2560/3/20/7,1

But I cannot get the frame buffer handle when I want to fill the frame buffer, like the following..

VPSS_FVID2: create handle is NULL
ti81xxfb ti81xxfb: fvid2 create failed.

Is it possible to let dm8168evm support such resolution?
