Just Delivered: Accell DisplayPort 1.2 to HDMI 2.0 Active Adapter

Subject: General Tech | February 11, 2016 - 04:48 PM |

Fabled to be "coming soon" since the launch of the AMD R9 Fury X back in June, today we finally got our hands on our first DisplayPort 1.2 to HDMI 2.0 adapter.

Coming from Accell, the aptly named DisplayPort 1.2 to HDMI 2.0 Active Adapter is a fairly self explanatory product. This adapter sits inline between your DisplayPort video card and HDMI TV in order to convert between the two interfaces. Previously, the only available adapters supported up to HDMI 1.4a, which only allowed for 30Hz connectivity at 4K.

Users looking to connect their 4K TV to a PC had their GPU options severely limited to exclude  all current AMD video cards and NVIDIA video cards below the GTX 950.

A quick test with the Accell DisplayPort 1.2 to HDMI 2.0 adapter with the AMD R9 Nano alongside our trusty Wasabi Mango UHD420 display proved that this adapter did indeed bring full 4K support at 60Hz and 4:4:4 color via HDMI on the Nano. This helps the R9 Nano become more useful in compact, HTPC builds.

Here we can see 4:4:4 subsampling working as intended

We also went ahead and tried this adapter with a GTX 780 Ti and found the same results. We were able to drive our 42" 4K TV at full refresh rate and color space.

It appears this adapter might not be fully retail available yet, but Accell has it listed on its online store for $37.99 shipping now. For users who have been looking for a way to get the most out of their older GPU (or a Fiji-based AMD part) and a 4K display, this seems like a no brainer.

Thanks for the head's up. Not a terrible price considering it does what it is suppose to do and is far less than I recall it was speculated to cost before it existed. With the Nano now selling at $500, where it should of on release, the price for this device seems not too painful.

I can't help but think that the Fury Nano sales won't benefit from this at this point. If I wanted to build a 4k htpc, I would wait for the next gen of gpus which will be better prepared to handle 4k.

Wait, so DP 1.2 needs an active adapter in order to output 4k@60hz via HDMI?

... via HDMI 2.0

As opposed to DP 1.2 to passive HDMI 2.0?

Not every 4k TV does 4:4:4 and especially not at 10-bit. The majority of 4k TVs only do 4:2:0 8-bit

That's why HDMI 2.0 was only a fad for the uniformed or those willing to pay upwards of $10k+ for a proper 4k TV which did 4:4:4 at 10-bit

I think your information is outdated. Right now there are more 4K HDTVs that support 4K60 444 over HDMI 2.0 than there are 4K monitors that use DisplayPort.

76 HDTV models that do full 4K60 444 over HDMI 2.0 tested and verified:

As for 4K60 10-bit 444, it is unlikely that HDTVs will ever support that since the official UHD Blu-ray spec maxes out at 4K60 10-bit 420. Anything is possible, but there probably won't be a need. There are currently several monitors that support native 10-bit 4K60 444 in the $800-1500 range, so it's not necessary to spend over $10,000.

That's an 8-bit list. You cant support HDR10 on 8-bit.

Your reading comprehension doesn't seem to be very good. LOL.

What is the "killer feature" for 4K content at this point? I didn't think there was much 4K content at this point. Without the content I haven't seen the reason to rush to 4K with legacy hardware instead of waiting for the next round of GPUs.

What is the killer feature for 2560 by 1440/1600?
What other selling point do you need other then its a big high res display. Personally I love the idea of gaming on a 40 inch display with higher pixel density then my 24 1080p display.

Was there an input lag test conducted? Does anyone know if there is any additional input lag by using this adapter?

February 12, 2016 | 08:54 AM - Posted by Anonymous (not verified)

These types of adapters don't introduce lag. DP-HDMI adapters don't, DVI-HDMI adapters don't, etc.

We're pretty sure there is not enough memory on this device to buffer a single 4k frame, which means it can't possibly introduce a frame of lag. It might buffer a few scan lines, but we're talking microseconds.

Club3D offers also an adapter, for almost two months and for less that $30

That's even better. Thanks.

The few times I've checked, I have never really seen this one in stock. Good to know see there will be multiple options at least!
