Got a Hisense TV a while back for only $400, which was an amazing price for a 65" 4K tv, but I can see why it's so cheap now, this thing is a piece of shit. I really just want to sit down and use my tv without having to troubleshoot. I have random moments where I just have to restart the tv, which is just really annoying. The OS on this tv is just shit. The big issue of today is the Chromecast, which has never been all that great to begin with. Casting to YouTube would just in general not do anything, at all, no error, just wouldn't work, and today, when I tried casting to it, it gave me an error saying, "untrusted device". Would custom firmware fix some, if not all my issues?
How about disconnecting it from the internet, plugging in an Nvidia Shield or CCwGTV, and using the TV as a 'dumb' one? Cause hey, if the panel itself is nice, and the thing is capable of displaying the HDMI input without nasty processing, overscanning, etc, then why bother with it's OS to begin from?
