Questions about Sony KD65AG8

I keep noticing that the TV reacts a bit slowly, is that generally the case with this model or am I unlucky with my device? My father also has a Sony TV (different model) with Android and it's much smoother on his. The latest update (8.0.0) has just been installed, but the response time is still slow.

Hello, Is the offer new goods or the sale of exhibition items, B-goods or returns ? VG Andre

Can this TV also be mounted with a wall bracket?

Does anyone have experience with this TV in combination with a Sonos Playbase + 2 Play 1. As I have already seen, the remote control is not with infrared and that is why you cannot change the volume directly with the supplied remote control. Does anyone know of a good solution? Could I just use a universal remote control (with IR) to control the volume of the TV / Playbasel? Does the TV even recognise IR or does it have to be a special remote control?

Which HDMI version does the TV have? 2.0 or 2.1?

The device is advertised everywhere with a 5-year guarantee. Here it only says 24 months. What is correct?

This device works with the Android OS operating system. Can I therefore not bring my Apple mobile phone directly onto the screen - with photos or something?

I had my last TV 15 years ago, I'm absolutely not up to date. In the last few years, I watched all the films on Teleboy.ch on my PC. Is there a Teleboy app that I can install on the TV? Or do I have to connect Teleboy via HDMI from the PC? Or can I access the Teleboy.ch website on the TV via a browser? WHICH OPTIONS ARE THERE AND WHICH IS THE MOST CONVENIENT? (I've heard that the USB connection of this TV or the electronics afterwards are very slow when playing, so you should/cannot watch the films via USB sticks).
