MIPI DSI panel resolution on i.MX 7Dual

The i.MX7 Reference Manual says the MIPI DSI resolution ranges up to SXGA+(1400 x 1050 @ 60 Hz, 24 bpp).


Is the x-res of 1400 an absolute limit or can this be higher if the y-res is lower than 1050?


I am trying to drive a LCD with a resolution of 1440x240 @ 60Hz, 24bpp using a custom MIPI DSI to RGB converter connected to the DSI port on the i.MX 7Dual Sabre dev board, but I see no RGB data on the DSI data lanes. If I change the driver and device tree configuration to 640x240, the data lanes have RGB data.


Any help/clarification would be appreciated.
