Whoever decides the naming conventions for these cables needs a collective smack round the back of the head.

Right now we've got 3 different types of HDMI 2.0/2.0b/2.1 that are all quite different - and the next step for doubling the bandwidth is to just go to 2.2. Surely HDMI 3.0 wouldn't hurt anyone as a clear distinction?!

cables longer than 1m now make the new standards actually viable! with cable tidying below desk and along a monitor arm 2-3m is a must.

have seen rumours know the new nvidia GPUs will have a newer displayport, but nothing on what HDMI version will be on them yet - be interesting to see what is the first GPU with both

It'll definitely be HDMI 2.1 on the new GPUs, 2.2 spec has only just been released and won't be in circulation for another 2 years.

The best thing for PC gamers is that DisplayPort 2.1 seems to be appearing on GPUs now and monitors releasing this year are also including it - so hopefully within 2 years or so we'll see those be the standard. Reduces the need for any sort of compression (although DSC is very, very good) and solves the Nvidia Alt-Tab black screen issue too.

@Baddass do you know what the deal is with display port 2.1b?

I’m a bit worried that some of the new monitors won’t be able to connect via the new longer cables!

… or is it the case that it’s just the cable and that the monitor / GPU doesn’t matter so long as they are DP 2.1?

Sorry to ask you specifically, I just know that you’re the the resident guru :)

Depends on the monitor specs, i.e. resolution & refresh rate combination.

Both the monitor and GPU need to support UHBR20 version of DP2.1 (e.g. the new MSI OLEDs shown at CES or Nvidia RTX 5000 series). If the monitor or GPU doesn't have UHBR20 support, they'll use DSC (display stream compression) to transmit the data, if the resolution/refresh rate is too high. More DP2.1b info will be available when the cables get released later this Spring.

Nvidia RTX 4000 only supports DP1.4a, which maxes out at 4k120Hz / 1440p251Hz / 1080p406Hz before needing to use DSC.

The below are for UHBR13.5 (supported by Intels Battlemage and AMDs RX7000 series GPUs).
4k maxes out at 229Hz at 8 bit colour depth (else DSC needs to be used).
1440p maxes out at 452Hz before needing UHBR20 or DSC.
1080p maxes out at 688Hz before needing UHBR20 or DSC.

TLDR, don't worry about DP2.1b, especially if your monitor doesn't perform above the limits listed, unless you plan to get one of these new GPUs and a monitor that supports UHBR20.

As far as I can tell, nothing it changing with the physical ports on input devices or displays. The spec has just been updated to accommodate certification for longer active cables. But any monitor or device that has DP 2.1 already, and are labelled as 2.1a should afaik work with those new cables anyway. Those ports could just as well be labelled 2.1b, and I expect manufacturers will just update their spec listings to have the latest version number :)

Aha, good to know. Thanks for the response :)
 
Is it just me or were there no new TVs or coverage of them from CES this year?
Would have been interesting to see if there was any new tech, features or specs available.
Would have been good to see them up to 144Hz (at 4k) or supporting DisplayPort for once.

LG announced at CES an entire refresh to the G5 range, refresh rate up to 165hz at 4k and moving away from the MLA layer process.

There was a fairly decent amount of TV updates this year!

there was lots of new TVs, LG/Samsung had brighter OLEDs with new panel tech, LG looks to add a new 4 stack blue layer and samsung increased efficiency in latest panels. Check out this for a quick overview, as usual TVs ahead of monitor tech
