It's 2018 and still no 4k monitor with 120hz or 144hz support?

I would be happy for 4k@90hz in a 40 to 50 inch freesync 2 or g sync

with both dp 1.4 and HDM1 2.1


as your not going to get 4k@120 with a single 1180 ti or any single card for years

Good thing about the chart you posted is that 4k at 120Hz using display port 1.4 is doable without resorting to any compression at all, so all I need is a 4K display that does 4k at 120 Hz along with freesync and i'm good to go....:)

New Display Port tech on the way, with the bandwidth increase it should do 8K/120 or higher and 10K/60.

They just started working on it though and as the article says, brings with it a new signaling protocol, which the last time that changed was 4 years ago with the introduction of display port 1.3.....Basically, expect this new standard to probably show up in 2020 or beyond most likely, as it takes time to work out the kinks.

Yeah, even now almost all monitors on the market are DP1.2

No one bothered with DP1.3 for years, and there are very very few monitors with DP1.4 right now.
 
So these two monitors are on the market now and the reviews are not favorable. Seems that many are complaining of backlight leaks and other issues suchs as flickering and dead pixels.

Edit: nvm, they aren't out, read reviews on different models.

The rumor is they are too be announced/released this month or next.
 
144Hz 4K .. so you can get no where 100fps ever until the generation after Volta :bleh:
 
What I want to know is how they plan to get 4K+144Hz+HDR on HDMI 2.0B since it would require 40Gbps data rate and at max with an active controller 2.0B can only reach 27Gbps.

The monitors do it over HDMI unless it is HDMI 2.1 but no video card supports it.

G-Synce will also add too the data rate as well so is it faked with some sort of Frame Interpolation? But that would add latency.

Display port is usually better.

1 - Windows 10 requires November 2015 update or newer.
2 - 7680x4320 at 60 Hz RGB 8-bit with dual DisplayPort connectors or 7680x4320 at 60 Hz YUV420 8-bit with one DisplayPort 1.3 connector.
3 - DisplayPort 1.2 Certified, DisplayPort 1.3/1.4 Ready.
4 - Recommendation is made based on PC configured with an Intel Core i7 3.2 GHz processor. Pre-built system may require less power depending on system configuration.

Taken from the 1080Ti spec sheet from Nvidia. So the 1080Ti is only certified for DP 1.2 but is compatible with "1.3/1.4"??? LOL Nvidia clarity at work...

So in a nutshell if they are going to use Display Port 1.4 then they would need to use data compression to do so. Its called Display Stream Compression so you won't be getting 10Bit HDR, it would be 4:2:2 which is 8Bit which is what 1080P does.

4K+144Hz+HDR 10Bit 4:4:4 would require more bandwidth then what HDMI 2.0b and DP 1.4 can support. The only thing that would support it is HDMI 2.1 or Display Port 1.5 but we'd need new video cards to support it as nothing right now comes with the standard and DP1.5 isn't available yet.

I thihnk we are going to see some trickery with these screens ala faked using an onboard chip to get the 144Hz feel. Until we see actual specs though.

My theory is that the screens can do 4K+144Hz+HDR 10Bit 4:4:4 but through HDMI 2.1 only and we'll see new video cards in July/August. Otherwise it will be 4K+144Hz+8Bit 4:2:2 for DP 1.4 and no HDMI 2.0b support.
 
5 months old and have not deen anything more on it

HDMI 2.1 VRR support will come to AMD Radeon RX GPUs with a future driver update
Click to expand...

Radeon Software will add support for HDMI 2.1 Variable Refresh Rate (VRR) technology on Radeon RX products in an upcoming driver release. This support will come as an addition to the Radeon FreeSync technology umbrella, as displays with HDMI 2.1 VRR support reach market.

sounds like RX cards just need a driver update for HDMI 2.1

https://www.overclock3d.net/news/gp..._radeon_rx_gpus_with_a_future_driver_update/1
will see in about two week if anything comes out at computex

but **** displayport and it's displayport link failures I think I want to try HDMI 2.1 VRR on a 47" to 65" screen
