Can you get me the output of "sudo cat

<div> Correct, but a TV is intended for videos only.
That's why it implements only the lower HDMI
standard.<br>
<br>
Interlaced transmits only halve the lines with each
frame, so a 60Hz mode effectively either becomes a
30Hz mode, halving the vertical resolution or
adaptive motion compensated which the know visual
artifacts. Depending on what the deinterlacing
setting on your TV is.<br>
<br>
You could just add a progressive 1920x540@60 or
1920x1080@30 mode manually and would have the same
effect with probably better quality.

If you can give us some more information what is
happening when the system freeze we could try to
narrow this down, but we can't spend much time on a
very specific use case in a driver which is in
maintenance mode.<br>

<div> Hi Alberto,<br>
<br>
well a frame rate of 24Hz is perfectly
reasonable for a TV and desktop usage.<br>
<br>
This is probably caused by the TVs limited
HDMI bandwidth and a refresh rate of 30/25
Hz for the interlaced mode isn't much better
either.<br>

Why do you think so?, the 24Hz

But apart from that if you

using an interlaced

See those resolutions only

I think we would just
