imx8mm displaying hdmi in 1024x768 VESA mode

[Belisko Marek]

Hi,

I'm using the 6.1 kernel for the imx8mm board in combination with the
lt8912 driver to have hdmi output available. When plugged full-hd monitor
image is displayed but when plugged an older monitor with max
resolution 1024x768 there is no image displayed on it. I have no clue
where to start looking but would like to ask if such a combination is
supported. According to the bridge vendor such resolution should be
supported so maybe I need to tune something on drm?

Thanks and BR,

marek
