CCGTV not working with 3440*1440 UWQHD screen

[El_gagaz]

I have my CCGTV working perfectly with my previous screen (HP 27F), but I'm not getting able to make it work on my new LG 34" Ultra wide (not curved). The new screen is 3440*1440 (21:9).

The screen is detecting no signal. Tried CCGTV  again on my old screen, and it works perfectly..

The led is light is white.

Thank you

Just noticed that if I connect the Chromecast to a different HDMI port, the moment I switch the display port, I see the Chromecast Netflix display for barely 1 second, then the screen turns black again and says no signal.
