Ben, would like to ask you something considering you are very knowledgeable.
I am planning to change the HDMI cable for my PS4 Pro as the default is too short, does the quality of HDMI cables matter?
I see some HDMI cables are 2.0, some 1.4, and some really expensive ones.
Did my research and some sites say that it doesnt really matter what HDMI cable you use, it's all the same?

dont spend too much on HDMI cable , just make sure its version 2.0 which only cost rm18.30 ( 1.5m ) at lazada , cheap and expensive basically perform the same quality

afaik hdr require 2.0 cable. in your ps4, if you select auto in video output, it will select the best option either 2160p YUV420 or 2160p RGB. if u enable hdr it will automatically use 2160p yuv420.
I've explained this before:

Common misconception.
All standard HDMI cables are built the same actually. A HDMI cable that came out in 2007 can transport 4k signals with HDR as long as its of sufficient gauge to maintain the distance the signal has to travel. You just need to make sure the cable is a high speed full bandwidth cable.
The difference in HDMI compatibility is at the ports, not the cable. Most people do not know this, which is why the exotic HDMI cable market is so lucrative.
The cable only matters if you are doing long runs. By long runs, I mean above 8m. The longer the run, the more the cable matters.
HDMI 2.0 cable does not exist, actually. It's a stupid term made by stupid marketers to sell their products. Because the bigger the number, the better it is, right?

Under a certain length, all HDMI cables (assuming they are built correctly) are the same. They are NOT called HDMI > insert number < cable. They're simply called a HDMI cable, nothing else. That's the correct term.
To add one extra bit of info however; since late 2013 there exists HDMI cables that are CERTIFIED as High-Speed cables. These are the so-called "HDMI 2.0" cables people are calling, which I always find hilarious because it's a term made out of thin air.
You buy a certified high-speed cable to transport 4k @ 60fps with 4:4:4 chroma at 8-bit depth. Most people don't need this cable because guess what? Their console don't even do it in the first place. The PS4 Pro only either lets you choose 4:2:0 with HDR or 4:4:4 at 1080p, end of story.
In short, if your need of a cable run is only 6 meters or less, just buy a cable built to the correct standards. They don't cost more than RM30.
If you need a cable length that runs for over 8 meters, then you will have to buy higher gauge cables, you may have to add a repeater, or if you need extremely long runs like over 15 meters, then you may have to buy a fiber optic HDMI cable (this one will cost at least your pinky and a toe).

I think cannot la change TV Hz. TV Info still show it run on 60Hz or 120Hz even input 24/30fps.
Generally speaking, if a TV or other display device showed you 24 frames per second, it would look really choppy. Movie theaters can get away with it because the images are so dim (usually a fraction of what your TV produces). If you were to display 24fps as 24fps on something as small and bright as your TV, it would flicker a lot. Even theaters don't really show 24fps. They use a rotating shutter to throw a black frame in between each film frame. Sometimes these rotate at 48 or 72Hz, so you're seeing each frame two or three times, with black frames in between. This is fast enough that you can't see it (obviously). So 4k TV still maintain at 60Hz or 120Hz.
What I mean "Upscale" is about 1080p ps4 to 4k TV. Nothing to do refresh rate or PC connection or PC monitor.
My question is about PS4 pro especially. If can choose 30fps or 60fps setting, is there any different on 4k TV? as in 120Hz, TV will multiply to fit it.
Then you should have made your question clearer.
Once again, I run my HTPC to my TV every single day. I have 2 modes for it, 60hz for PC games, 24hz for movies. It is done through the GPU's control panel (Nvidia, in my case). Hell, I'm typing this post right now at 24hz with a TV episode of Arrow paused just to reply to you.

Movies aren't choppy at 24hz for me on a TV purposely set to 24hz, they are inherently "slow" of course but that's how they are filmed and that's a whole other topic.
To answer your real question:
My question is about PS4 pro especially. If can choose 30fps or 60fps setting, is there any different on 4k TV? as in 120Hz, TV will multiply to fit it.
If the game is in 60hz and the TV is NATIVELY in 120hz, then no there is no difference. You would still see 60fps (assuming the game holds at 60fps 99% of the time). But I can count on one hand how many actual, NATIVE 120hz 4k TVs there are on the market right now.
Unless you want to play a game at 60hz, enable interpolation or BFI on the TV just so it is at 120hz to reduce motion blur; then be my guest. I'm not going to entertain the input lag hell it comes with.
