1.3 Display Port

Does anyone know when display port 1.3 monitors are expected to be released?

When somebody actually makes working DP 1.3 chipset ready for mass production. Will this ever happen is the question. At current rate, Thunderbolt may achieve more uptake before DP 1.3 ever gets released.

It is my understanding that there aren't the modules ready yet for DP 1.3

you might see some extremely high end screens by the end of 2017, but these will be sparse - I know it deffo wont be 1h 2017
 
It appears either Displayport Tcon silicone manufacturers are having problems designing/producing them or they think there isn't a financial reason to make them before 2H 2017.

Just to put into perspective how sorry of a situation this is; by the time the first DP 1.3 monitors hit the ground the specification/standard will have been out for over THREE YEARS!

Quite a lesson for standard makers to produce a standard which is actually feasible to implement, unlike "here is a new standard for you - we've doubled clock speed, now make it work!" /s ;)
 
Could the manufacturers do what they did with the first 4K monitors and take a DP signal and split it across two electrically separate 1920x2160 displays?

This works well for static images only - its hard to synchronize two separate displays to scan at exactly same time (otherwise you will see "tear" in the middle on anything quickly moving). DP has some provisions for stream aggregation but its flakey (since no one is actually using it much) and would be nightmare from customer support standpoint (since most likely will cause common compatibility issues with multitude of possible hardware combinations).

Also first-gen 4K displays were a bit different, since they still used single DP cable. Going above 1.2 will require aggregating two separate cables (like 5K Dell monitor does), which is quite more prone to problems above.

I'm not sure that's correct. A DP 1.3/1.4 cable is capable of two 2K streams at 120 Hz. Current high-end cards can output that, so all the monitor has to do is split them. Assuming you can get a cable. And speaking of 5K, I remember reading - probably on Hardforum - about someone trying one of the 5K monitors with quad Titans and not getting tearing.

You mean the cable which nobody was able to make yet? ;)
Because there is no hardware to actually test this cable with.

The problem is not making the high-refresh (or at least 120Hz) 4K panel. The problem is pushing this bandwidth over the cable. E.g. NEC PA322UHD-BK-2 already uses its 4K panel in 120Hz in lower resolutions when DP 1.2 is enough.

And speaking of 5K, I remember reading - probably on Hardforum - about someone trying one of the 5K monitors with quad Titans and not getting tearing.

It does work sometimes, sometimes it does not. First gen 4K displays also worked ok for a lot of people, but many had problems with them.

Hmm, I've had the Dell 5K display that uses two DP 1.2 cables to do 5K @ 60 Hz (which could also be implemented to do 4K @ 120 Hz). I don't remember any tearing of the left and right sides of the display while gaming.

But then again I had V-Sync ON, which should force the left and right sides to be identical.
 
Yes, so in theory we could have dual DP 1.2 input 4K / 120 Hz displays for many years now if a monitor manufacture had the wherewithal to produce one. I know I would surely have bought it.
 
TBH 4K does not really need high refresh DP 1.3 - since I doubt significant amount of people will be actually able to drive UHD @ 120Hz - it will require quite insane hardware even for the near future.

All is needed is good-quality 120Hz capable scaler and 4K 120Hz+ capable panel - to be able to use 4K @ normal 60Hz for crisp desktop/office work and games at 1080p/1440p with high refresh. 1080p should rescale pixel-perfect, and 1440p can rescale almost-perfect checkerboard as PS4 does.

This is far more feasible than trying to make/waiting for DP 1.3 to work.

Again, NEC has being doing it for ages with their pro 4K, just that no gaming manufacturers picked the same idea yet (maybe lack of above scaler is the issue).

I've got to disagree with you there. Plenty of older games can already be run at 60 Hz at 4K. Just because they're older games doesn't mean that they're no longer good.

For example, I'd love to be able to play Borderlands 2 at 120 Hz on a 4K monitor. My SLI Titan XMs would easily push that; a single TX will exceed 60 fps.
