A:AnswerWhile I cant say for sure since I have PS5 disc version; I recall the Geek Squad people telling me it has 60Hz playback. I didnt see any screen tearing or artifacting when they played an 8K video on my new 8K TV. These images are from my Galaxy S21 Ultra which only shoots images in 4K quality.
A:AnswerLength of cable shouldn't matter. If each length does the same thing; there's no reason to get the longer cable. If your usual brick and mortar store doesn't have it, you can order it online and it'll be shipped from the nearest store to your current address.
A:AnswerThis depends on what type of device you're connecting to your TV/display. And also what kind of resolutions your device outputs are capable of producing. If your connected device is capable of producing output in 4K and your connected display can show the video; there's no cause for concern. Traditional 4K output is in the 60Hz range.
A:AnswerI bought this cable with my new Samsung 65" Neo QLED 8K. This cable should provide a high quality signal from all your connected devices. While I'm not familiar with the specs on the 82" QLEDs; my TV has an AI upscaler which improves the video quality of any incoming video to near 8K quality. They told me this function works best when the source is external to the TV and not a pre-installed app/streaming service on the TV.
A:AnswerThis cable, an entry level HDMI for Audiooquest that is rated at up to 10K professional UltraHD video (48Gbps). There are 4 balanced audio/video pairs capable of 12 Gbps each out of the 19 conductors in the cable. These conductors are long grain copper. If you're wanting a higher silver content for greater surface conductivity, get one of the higher end models. This cable is rated eARC LGC Level-1 ND. This cable is constructed to be mono-directional for proper noise dissipation.
