A:AnswerIt connects devices with HDMI ports... typically televisions to cable boxes, blu-day players, etc. It provides better pictures and sound quality than the red/white/yellow cables.
A:AnswerIn regards to Hz, HDMI cables will do whatever your TV is capable of. Hz is a measure that, in layman's terms, is the refresh rate, i.e. how many times does the screen refresh in a second to produce the best possible picture. The higher the refresh rate (Hz), the less motion blur you see. Today's LED TVs have a standard refresh rate of 120-240 Hz (can go up a little more technically, but nobody is manufacturing the TVs to do so); older LCDs pretty much max out at 120 Hz; and older plasma televisions maxed out at 600 Hz, which is why you will hear a lot of people tell you that plasma televisions will still outperform most newer LED and 4K televisions (I tend to agree here having currently own a 4K and plasma). Even the earliest adaptations of the HDMI cable, pre-4K could handle the load of the 600 Hz plasma refresh rates with ease, the difference in those cables vs. the newer 4K HDMI cables is data speed. 4K needs 15 Mbps to produce the necessary 4K picture, and these cables can handle up to 18 Mbps.
Sorry for the long, drawn-out answer, but I hope this helps.
A:AnswerNo... no matter what someone says, digital is digital and transfers sound and picture at 1080p, etc. better cables are built better, creating longevity and quality at the pins (not missing pins), etc. Also, make sure your cables are certified!
If you are worried about the picture you can check the quality of your digital feed, etc. and if you have a great feed and want to get a better image then you are stuck going to 4K, but will only experience 4K with 4K feeds. Also, if you upgrade to 4K you will likely want high speed hdmi cables which increase bandwidth, etc.
I'm not an expert... just two cents from an average guy! Hope it helps.

A:AnswerIf you are hooking absolutely nothing up to your TV then no. But if you are hooking it up to any type of cable TV, dish, dvd player, anything at all you will need it.
A:AnswerYes they will. They are designed to and will. They work great with my Sony 4k and Yamaha receiver and can transmit the audio for an Arc channel hdmi. They are the latest that hdmi has to offer and do what you expect them to
A:AnswerGo with this Rocketfish cable. It's 2.2 compliant, though it doesn't say so on the box or on the site. Pretty much if it says it's high speed or supports HDR or UHD you are good to go. I just bought this yesterday and just posted a review. The cable is well made and the connectors are very sturdy. I work in the video industry and generally use no name generic cables that are fine. :) The extra cost of the SKY cables is just profit and a marketing strategy that says 'People who don't know will buy the more expensive version based on a perceived difference in quality.'
A:AnswerGo for the 4k cable. It does make a different with picture quality. I tried using my old standard HDMI cable for my PS4 when I upgraded to a 4K TV and it wasn't the same. Everything is clearer, brighter and smoother with a 4K cable. This one is a very reasonable price and I have it on my blu-player. (The 4K cable I have for my PS4 now cost in excess of $280 and is phenomenal.)
A:AnswerThis is all dependent on your specific application. You choose the length of the cable that specifically meets your needs. A 4 ft cable could work for some, and others may need 25ft or more.
A:AnswerAny HDMI cable should do the job. If you want to be sure it's the best cable around, look for cables labeled as 'High Speed', and the ones that have a sticker on them saying 'HDMI Certified Premium'. What really effects the quality is both the TV itself, as well as the source of the video playing.
A:AnswerI recently upgraded my television to a 4K and had old RCA cables which made the picture fuzzy. When I swapped to the 4K hdmi cables the picture was immensely better. I used 2 cables, one from the receiver to the TV and one from the box to the receiver. My suggestion is to use the 4K cables for a much better picture. Rocketfish cables are pretty pricey but there is an off brand available for a lower price. I used one of each (because the Rocketfish was on sale at the time I bought it). I think either cable will work fine.
A:AnswerNo - upscaling happens in either the player or the TV/Projector. This cable is Premium Certified for 4k UHD so it will handle anything the PS4 Pro can output.
