Santa gave me a new TV this year, a Sony Bravia KD55XE9005
It's pretty, but let's quibble!
The control system is labyrinthine. The most used bits are in an "Action Menu", the rest is buried at the bottom of the Android Home page that has the Netflix/Amazon pay us $$$ links I don't use. Sony has abandoned manuals in favour of Internet help pages, up to date but slower to access.
The previous TV couldn't cope with 1080p, no problem with this one. The computer's graphics card is willing to display 2160p but with my present three screen setup (!!) runs hotter if it does, more so with games. EVE would be unplayable anyway due to tiny text, a known problem.
4K is presently only broadcast by subscription, so that will have to wait.
The Humax Satbox and Sony disk player link in, the Sony Amp allows sound control or full control but not both.
The TV comes with an "IR Blaster" that ingeniously attaches to devices and replaces their remote controls to some extent. The Humax TV guide is however easier to use and has built-in catch-up streaming, the TV can access it but is inclined to cause screen freeze if the wrong button is pressed.
Time wasted trying to fix satellite cable only to accidentally find it was the HDMI plug next to it that was loose. Grr.
Mirroring from tablet to big screen is easy - one button.
Tablet remote control app? Fine!
