Supported resolutions on IMX8MQ via HDMI

we would like to use the IMX8MQ to display a range of resolutions via the HDMI port (e.g. 1920x1200@60), but the driver only seems to offer a limited number of resolutions, and most of the ones we want to support are not among them (from what I understand, the pixel clock can only support a finite number of frequencies?).


My question is: Is this a hardware limitation, or could the driver be expanded to support more resolutions? Furthermore, if it is a hardware limitation, could the DTG (or some other system) be configured in such a way as to increase the blanking times, so that we could "fake" the resolutions we want to support?


Best regards,
