HDMI 2.1 Specification Brings 4K@120Hz / 8K@60Hz

[leipero]

Well, having being late to the LCD party (got one only about 10 yeas ago), I remember vividly the eye strain from CRT monitors and TV.

As for the CRT refresh rate, some people know squat about configuring video modes on a PC. At work, I have seen a lot of people using misconfigured screens, to the point it piss me off so much that I grab the mouse/touchpad of their hands and configure it myself.

I've never experienced eye strain, it is possible at lower refresh rates, especially from CRT TV's (50/60Hz) if you are too close to them when watching. Yeah, I've got pissed off by people not caring/configuring their screen way too often in past also, LCD's at least solve that problem. Not a fan of glossy finish either tho, and I never saw CRT without it.

USB-C in DisplayPort mode is a DP 1.4, so it can do that already.

dp 1.4 is 32.4 raw gbit/s, which is obviously out of range for any contemporary usb
and dp 1.4 can do 4k@144hz only with lossy compression

now it's common to find IPS monitors rated at 1-2 ms

you can easily find monitor rated for 1:1000000 contrast, ratings are limited only by imagination of writer.

Still waiting for those well priced korean 4k@120 DP freesync monitors to show up.

do you have videocard which is able to produce 4k@120 ?
i am waiting for any freesync 2 monitor(current "freesync 2" monitors are out of spec), but i am not aiming higher than 1440p, which is more than 2 times less pixels to draw

DisplayPort alternate mode in USB supports DP 1.4 just fine though.

with what bandwidth?

[zamadatix]

with what bandwidth?

DP 1.4 describes the bandwidth... 32.4 Gbps.

[pal666]

DP 1.4 describes the bandwidth... 32.4 Gbps.

no, it describes its maximum bandwidth. cables have their own limits.
in our case 4k@144hz is achievable only with up to 1m cables and lossy compression

Or technology such as active matrix (O)LEDs and better liquid crystal panel materials.

no, ratings are not limited by technology in any way
btw, you can not "easily find" neither oled monitor nor anything else with real high contrast

it is marketing material, i have no idea how it will stand in testing
they say they have two layers of liquid crystalls with second one is somehow "different"(if it is better, why it is not used in first one?). with two layers you could have squared contrast of one layer, so it could work, but it could work not as good as in presentation
