I bought the Chromecast with Google TV (4k). Unfortunately, I noticed that there is an unsolved known issue with 4k LG monitors (mine is the 27UN83A) that has been reported in older posts (see: Chromecast with google tv an LG Monitor or Newly bought Chromecast shows blank black screen). Briefly, the signal of the Chromecast is lost after 1 or 2 seconds when manually switching inputs in the LG monitor (for example: HDMI->DisplayPort->HDMI). The only way to get the signal back is by going into the settings of the monitor and enabling/disabling the option "HDMI ULTRA Deep Color" (enabling or disabling this option will both get the signal of the Chromecast back). Switching inputs in the monitor does not affect the signal of other devices that I have connected to it (macbook pro, nintendo switch). Therefore, this tells us that the problem is indeed the CCwGTV(4k).
Some users claimed that the issue could be solved by connecting the CCwGTV(4k) to a HDMI switcher or a HDMI extender (see this response). However, in my case, such workaround did not solve the issue mentioned above (the HDMI extender that I purchased is this one: UGREEN Cable Alargador HDMI, 4K@60Hz Cable de Extensión HDMI Macho a Hembra Soporte 18Gbps, 3D, HDR,...).
Do you know any other solution? (please do not copy-paste answers from previous posts without testing if it works). To me, it seems this is something that could be fixed with a software update. But maybe there is not enough interest in fixing it because the most common usage is on TVs and not on monitors. Is that correct? If so, I am going to return the CCwGTV(4k) and buy an Amazon Fire TV stick 4k Max instead (which I haven't tried yet, but hopefully won't have this annoying issue).
