DisplayPort and 4K

Re:DisplayPort and 4K by jacobolus on Monday February 17, 2020 @06:52PM (#22352108)

Personally I think 24" 4k displays (along the lines of https://amzn.com/B00PC9HFNY or https://amzn.com/B01LPNKFK0/) look a lot better than 32" 4K displays. YMMV.

Though if you have the space (a very deep empty desk) to put your display like 6 feet away from your face, then the 32" might be a decent way to reduce eye strain.

They will do for sure since you can run them with 200% scaling. That scaling factor gives you the cleanest fonts. Fractional scaling is not as good.

I’m using a 27" screen with 4K which is ok. But I would definitely upgrade to 5k to get 200% scaling once display standards properly support it (Thunderbolt 3 will not be a permanent solution) and screens are affordable

I'm wondering what you mean by "Thunderbolt 3 will not be a permanent solution".

I had gotten the vague impression that Thunderbolt 3 is in line to be adopted more-or-less whole-cloth as USB4. Is that not accurate?

Thunderbolt is much more than an just a display link. You can think of it as something as PCI Express, plus some USB and displayport compatibility. It can technically support everything, but might require custom drivers. I don't expect it to become a mainstream solution for "just pushing down some pixels from A to B" due to its additional complexity and cost.

I haven't followed USB4 too much. I expect it to again have multiple "levels" like USB had before. And whether some or all of those will be high definition video capable it to be seen. For USB-C video was just a mere alternate mode which switched the meaning of the wires inside the cables to displayport. Doing video over the PCI Express subsystem of thunderbolt is a different story.

TB3 can embed displayport, even 1.4 with latest versions (allowing for 8k video, though if I remember correctly, it was 60Hz using only one of the "fake" techniques like compression or interlacing, not sure exactly which). The hard bit is finding which chipset a particular device uses and if it will do 8k (more recent ones) or not.

If 8k is supported, so is 5k, which is kinda getting mainstream.

USB4 will definitely be high definition video compatible, that much we know.

From reading this[0] it looks like USB4 and TB3 will be broadly compatible, modulo the usual sort of tiresome licensing and compatibility BS our industry loves to burden us with. Pity.

I also went with a good 27" instead of a cheap 32", but mine is 200% scaling. I figure this will become a secondary monitor I can use for a very long time.

I'll buy a 32" with no bezel when I can get it with a Thunderbolt 4 port, and my desk will be right about maxed out.
