The video resolutions are independent of the Mali accelerator. Currently the Linux kernel driver supports the following resolutions in HDMI mode:
While the timing generators can be configured for other resolutions as well (see LCD output), one would have to figure out how to add new resolutions here and what is exactly supported by the hardware, but I think not all documentation for the AW Display Engine 2 are out in the open...
