I assume that when starting up the box displays the welcome screen in a low resolution so any TV will display that message and during the process of installing the software it then checks the native resolution of the screen and sets the output accordingly, but what happens when AFAIK the 360 only can only output 4K is it only able to recognize TV's up to 4K correctly or can it recognize 8K and then set the output to 4K ?
I would have hoped that after 2 engineers at least one would have tried a direct connection and a different HDMI cable and also changing the resolution settings.
Maybe it is a TV compatibility problem, let's see what the third engineer can do.
they replaced the box and the welcome screen came on but then I got a blank screen again, I can hear it but cannot see it 😳 they are still staying the tv is not comparable the the 360 cannot support 8k. They have asked me to ring Samsung to see if we can change the resolution on the tv, not sure if that will work 😳
looks like I will have to terminate from virgin which is a shame after being a customer for 15yrs
if this is the case virgin will lose a lot of customers if they cannot keep up with technology
Sorry to hear today's visit didn't go well, as I am sure your TV is capable of upscaling lower resolution signals which it must be doing if you can see the welcome screen then I would have thought if the engineer changed the resolution setting from automatic to 1080 or 4K using his monitor then you should have been OK.
If it is a case of the 360 detects a 8K TV and switches off the video then it's a lack of foresight from Virgin.
Possibly start a new thread asking if anyone has a 8K TV working with the 360.
Have you considered it could be your TV? From a Google search I see other Samsung Qled 8K owners are getting a blank screen with audio. There are also YouTube videos covering this problem. Can you access non VM content such as the native streaming apps on your TV?
