I’ve tried everything, switching pictures modes turning things on/off resetting them, the XSX just doesn’t see my OLED65B9PLA as a 4K screen! 1440p is a great step up and everything is great but iv paid for 4K gaming and it’s non functional.
This was Microsoft’s last response after exhausting all the setting tutorials they sent me...
Unfortunately, in this case the LG OLED65B9PLA is not compatible, since you tried with the Samsung one and no issues were detected.
Therefore, what you can do Mandip is to get in touch with the manufacturer, and they will check the issue with you, since there is nothing we can do from our end.’
Nothing back from LG either yet, we wait....
My Xbox One X detects my B9 (same model as yours but 55") as 4K, no problem, and shows it as being compatible (all ticked) in the TV Information on the console. Ditto for my PS4 Pro. Both have worked flawlessly in 4K mode at 60 Hz for the year I have owned the TV. I even briefly tried 1440p @ 120 Hz on the XOX but, of course, that console doesn't support 4K @ 120 Hz so that has never been tested. I'm waiting for my PS5 next week to be able to test that (fingers crossed, eh?).
Sounds like there is a bug with the Xbox Series X to me. Looks like you will have to wait for a response from LG on this issue, unfortunately, but as more and more people start owning these systems then the more likely it is that more issues will be reported and, thus,. LG and Microsoft will start to take notice. Bad rep is damaging after all.
*EDIT*
Are you running your XSX through some kind of passthrough by any chance?
I remember when I had Sky Q installed. The engineer set it up as with my Sky+HD setup so that the cable box was connected into my X1X and the HDMI from my X1X was connected to the TV. However, when he went on to setup Sky Q it would not detect my was 4K capable even though everything was using 4K-certified HDMI cables.
Turned out that the passthrough on the X1X was not capable of passing through a 4K signal (IMO a massive oversight on Microsoft's part) so I ended up having to buy a 4K HDMI switcher box so that I could use my X1X in 4K along with my Nintendo Switch as the other 3 HDMI ports were being used by other devices (Sony 4K UHD X800 BD player PS4 Pro, Sky Q). This works fine.
Sorry if I missed one of your posts but I didn't see any mention of testing the HDMI directly into the TV from the XSX.
