ASUS ROG Announces First Monitor With Display Stream Compression Technology at E3 2019

ASUS ROG at AMD's Next horizon's event introduced the world's first Display Stream Compression (DSC) capable monitor. The new, 43" behemoth makes use of industry-standard DSC to enable 144 Hz gaming at 4K resolution via a single data cable, with no need to hack image fidelity down to pieces (potentially) by usage of chroma subsampling. AMD's Navi chips will feature this technology, which is why ASUS ROG took to AMD's event to showcase the new monitor.

FreeSync 2 HDR support is guaranteed, as is a Display HDR 1000 rating for increased contrast and improved visuals for HDR content. There's 10-bit color depth available, and the display covers up to 90% of the DCI-P3 gamut. No pricing or release date have been confirmed.

Display Stream Compression = huge input lag (besides potential image fidelity loss)

no thx


the only way towards uncompromised 4K-120+Hz gaming atm is HDMI 2.1

You have facts to back up your statement or are these just throw away comments?.

An assumption. I'll wait for testing before jumping to conclusions.

What about the Color Compression on the GPU ?

I'd be more interested in the HDR1000 part, but this is too big for my needs and it will cost in the $3,000 area.

Dude, I'm not sure you know how DSC works...
And... HDMI 2.1 also uses DSC.

DSC has more lag than no-DSC

and yes, it does, but only for 8K@120, 10K etc.

for 4K-120 48gbps doesnt need DSC

I mean HDMI 2.1 48 gbps is factually better, it can do 4K-120 4:4:4 10-bit (or even 12-bit), no DSC, with bandwidth to spare


the only issues are lack of devices (although LGs 2019 TV line has full HDMI 2.1) and lack of GPUs

but both of those should be remedied by 2020

Yeah these are just bandaids until HDMI 2.1 becomes widely adopted.

[Citation needed]

If it can compute it within the display cycle I see no reason it should add lag.

How does VESA’s DSC Standard compare to other image compression standards?
Compared to other image compression standards such as JPEG or AVC, etc., DSC achieves visually lossless compression quality at a low compression ratio by using a much simpler codec (coder/decoder) circuit. The typical compression ratio of DSC range from 1:1 to about 3:1 which offers significant benefit in interface data rate reduction. DSC is designed specifically to compress any content type at low compression with excellent results. The simple decoder (typically less than 100k gates) takes very little chip area, which minimizes implementation cost and device power use, and adds no more than one raster scan line (less than 8 usec in a 4K @ 60Hz system) to the display’s throughput latency, an unnoticeable delay for interactive applications."

You can conclude from this that the input lag added will be insignificant.

I'll believe that when I see it

regardless, its still compression and still a crutch

only because DP 1.4 bw cant handle 4K-120/144 4:4:4 10bit
but HDMI 2.1 can


but if you cant wait or if monitor makers ignore HDMI 2.1 and continue with DP 1.4, then this is the best opption

this monitor have probably FPGA chip inside to decompress. It is tech demo, won't be on sale at all

This is a fail, better to wait for hdmi 2.1 monitors.

It's literally said in the link. It's one scanline which is 1/2160th of 1 frame on a 4k monitor. Furthermore at 144hz which is per second we are talking fractions of miliseconds so large it's in the statistical anomaly range.

For the non believers out there the only reason this is coming out now is because VESA clarified the specifications with dp 1.4a. This is something that has existed since dp 1.2 but finally got nailed down.

Sorry but I"ll take the word of an international standards committee over your disbelief.

When this monitor got shown off at computex earlier this year it was only spec'd as HDR 600. Then Acer showed off their 4k 144hz 43" monitor which has HDR 1000 certification. And all of a sudden this Asus monitor becomes HDR 1000.

Well, there are those that swear they can see 4k on a 5" screen, you can bet there will be those that will be hindered by that 8us delay as well :D

so why are you sooo convinced of your view point and then go "I believe it when I see it" when someone is challenging it.
What dont you "believe it when you see it" with your lag fear mongering?

No thanks, I can do one more cable.

See this is the waste of time/effort/resources on petty non-issues, convenience, where we could be using that for something better, like ummm making a better bios screen with proper english instead of broken shinezo-engl that I'm quite getting tired of, for starters!!!!

Thanks to all the trade troubles in the world of politics, most of manufacturing is moving out of [ISPOILER]Red[/ISPOILER] China and into places with better english-taugh workforce so we can, in, what is, 2000andeffing20 have a proper english BIOS screen. [ISPOILER]Go Taiwan, The Free China![/ISPOILER]

EDIT: Many more things not just better english in manuals and stuff, but better communication back and forth with rest of the world and possibly more features/build/execution-quality as a result of less middle-men (transporters, shipper, contractors, dealers, translators) as the user feedback may make it easier down to the source companies and even some of the workforce, remember, an engineer might do some idea or direction that he gathers from the world at large, socials, or he reads on a forum, without having to be ordered by the management to do it, chinese wor... ehm slave-force probably doesn't have much time (and/or a means to for that matter) reading forums, nor time and energy implementing some cool extra features.

So there you go, THE TECH COMMUNITY, am I wrong? That should ease the digestion of the doom-gloomy newscycle about tarrifs now. Short term price and availability woes, for eventual long-term and various benefits.

So this will be "Gsync compatible" if I use a Nvidia gpu (like GTX 1080) ? Not looking to stream any game.

words from a site mean nothing

only independent reviews of this monitor/other DSC monitors will prove/disprove



you missing the point though, in that HDMI 2.1 48 gbps without needing any DSC is superior to this for 4K-120/144

I want the superior option rather then inferior one (no matter how inferior)

Please tell me which GPUs do have HDMI 2.1?

So basically you never buy anything, because the good stuff is always in a pipeline somewhere, waiting to be released. Sad, really.
