Hello,
Current firmware: GTMedia_X8_Release_V285_20210908.zip
Connection over HDMI.
Some broadcasters send both 16:9 and old material in 4:3.
Aspect Ratio is set to auto, but the HDMI signal does not automatically switch to 4:3!
You have to manually force the TV set to use 4:3.
Bug: X8 does not auto switch to 4:3
