Apple TV 4K won't display on LG TV (Q60R) tried different HDMI ports/cables - no luck Greetings, Never had this problem with my other TVs (all Samsung) with any Apple TVs. I just got a Apple TV 4K 3rd GEN, & attached to HDMI Port #2 on my LG TV, but get no display output, on this TV I have a Spectrum Receiver attached to the same TV on HDMI Port #1 & never had a problem with this setup. With my other TVs (Samsung) I've got attached Apple TVs (a year or two older than the new one) & never had a problem viewing content from the Apple TV. I had no problem setting up & viewing the new Apple TV 4k on my Samsungs, I even swapped out HDMI cables with the new Apple TV on the LG TV (again, no luck) In short, I can view output from any Apple TV on Samsung, I just can't view on the LG (with any HDMI cable or any HDMI port). This new Apple TV 4K is new right out of the box, I've got a new Monster 8K 48 Gbs cable, just seems something with the LG is prohibiting the display output, there aren't many settings to adjust. Just wondering if anyone out there in the Apple TV world had dealt with this. Thanks

Apple TV Connection to Polk Magnifi MAX not working 4K I have a problem connecting an Apple TV 4K to a POLK MAGNIFI MAX soundbar, Dolby Atmos is available but the apple tv is purple, after changing the video mode in the settings the colors are ok however there is no 4K resolution available. The soundbar supports on each HDMI IN 4K HDR. The HDMI cable is correct, in connecting directly Apple TV to the TV works ok, but then I have no Dolby Atmos sound. Soundbard connected HDMI ARC OUT to TV HDMI ARC, Apple TV to Soundbar HDMI 1 IN Anybody may have encountered a similar problem and can help?

Apple TV will only set at SDR (not HDR), TV shows HDR 10. I'm I really seeing HDR 10? I bought a new Vizio HD TV. It is connected to my Yamaha Adventage RX850 as is my Apple TV. My Apple TV will only go up to the SDR setting. It will not go to HDR. When I watch a TV show through my Apple TV, the TV says it is showing HDR 10. My question is this: is my TV really showing HDR 10 or just upscaled SDR? My receiver is an older discontinued model, but works great. When the TV I'm replacing (an older LG model on which the picture was going darker and bluer) was connected to the same system, the Apple TV would set to HDR. The problem now is probably due to the older receiver. When I bypass the receiver, the Vizio shows HDR and Dolby Vision. Everything is updated. Nothing to be done there. But I still have the question: Is my TV really showing HDR 10 or just upscaled SDR? Thanks

Please specify your brand and model amplifier/AV receiver, so that we may look up the specs that apply in this setup.

Please specify your model Apple TV box.

If this Apple TV box was previously connected to a setup/TV with different video capabilities, then that is something that needs to change in the Apple TV settings too. Apple has devised a way to do that “blindly”, using the remote:
