1080i 50hz resolution for live TV

kowalmisiek · March 29, 2018 at 4:30 PM

Hello all.

I have a problem. I have 4K TV and I have my HTPC connected to it. Intel Kabylake integrated graphics card. I noticed the jerking of the image while watching live TV. Currently, I have a resolution set to 3840x2160x50hz. When I reduced the resolution to 1920x1080x50hz it was better but still the image jerks were visible. When I set the resolution of 1280x720px 50hz it all worked well.

In the code menu there is no setting option 1920x1080i x 50hz. Live TV is being broadcast in such a resolution.

How to set it up in kodi for Live TV to work at this 1920x1080i x 50hz resolution. And all the rest in 4K.

I noticed that when I set the resolution of 1280x720px50hz in my menu and set 1920x1080i x 50hz, a smudged bar appears at the top of the screen. It is visible during movement.

Set your resolution to 1920 x 1080p.

In settings activate Adjust refresh rate.

In your box u-boot starts in 720p mode, LE is trying to use it causing unsynchronised picture.

You can verify and fix via setting environment variables 'hdmimode' and 'outputmode'.

ssh into your box and run below commands (first code to verify, the second to set).

See how you go. Sorry i don't have your hardware but can only advise on the little knowledge i have with this issue.

Code

fw_printenv hdmimode
fw_printenv outputmode

fw_setenv hdmimode 1080p50hz
fw_setenv outputmode 1080p50hz
