Will there ever be a DP 1.2 to HDMI 2.0 Active Converter

Postposted on Wed Aug 13, 2014 5:54 pm

I'm actually thinking of getting a 4k TV (Not for gaming), but all of the prospective choices include only HDMI 2.0 for 4K@60HZ. As the only TV's with displayport, two panasonics:

are ridiculously pricey, I'm reluctant to get them. I just bough a gtx 760 (horay!) a short time ago, and I'm quite worried that the adapters aren't coming out...

Could anyone shed some light on the current state of affairs for DP 1.2 to HDMI 2.0 adapters?

The main issue: Is that HDMI 2.0, or 1.4? I've never been able to find that vital piece of information for that specific adapter.

Nvm. The reviews are atrocious, and my desktop gpu has full sized DP, not mDP. (Although I could use it at 52 hz with my macbook pro at 4k)

Yeah, those mini-to-regular adapters should be fine; there's no electrical difference between the two, it's just an inconvenience.

The issue is: Is the adapter hdmi 2.0, or hdmi 1.4?

Ah, well, in that case I'd say: sure, there will probably be one eventually. I'd keep an eye on monoprice for one.

Given the experiences I've had with active adapters, though, you may be better off buying a video card with an HDMI 2.0 output.

Looking at it the only difference that would impact this adapter for 1.4 to 2.0 is 30Hz to 60Hz frequency.

Why don't you go to Moshi's site and ask using their support links?

Looking around for the part number (99MO023208) you can find listing dating back nearly a year which is before all the HDMI 2.0 circuitry hit the market. I believe it is safe to say that it is HDMI 1.4 so you'd only get 4K at 30 Hz from it.

All the HDMI 2.0 stuff I've heard coming out in 2014 was due at the end of the year.

After a bit of Google-fu, I've found one erroneously claiming to support HDMI 2.0. The big catch is that this is a passive adapter which will relay on TMDS pass through when the source has HDMI 2.0 support. Of course without any video card supporting HDMI 2.0 out yet, I think it is safe to say that there isn't any adapter on the market capable of 4k@60 hz via an HDMI adapter today.

Registered here just to post this.

Adapters will be out next year.

I can say this on good authority because I found the actual manufacture who made the chips that do the DP 1.1 -> 300 Mhz TMDS (hdmi 1.4) conversion and emailed them over a year ago and that is how I found out accel cables/bizlink (who they partner with to make the dongles with their chip) were coming out with their active DP 1.1 -> HDMI 1.4 adapter (several months before they released it).

I recently contacted them again and got verification they are indeed working on a chip to do DP 1.2 -> HDMI 2.0 (600 Mhz TMDS) conversion and they are currently in the works with accel/bizlink again who should have the dongle available in Q2 2015 (or possibly Q1) so they should be out sometime in the next 9 months (maybe a bit sooner) but sometime next year.

Awesome. Thanks for the info.

No reason then to buy a 4K TV until next year then (unless there are video cards that I've missed that have HDMI 2.0).
