Gtx 970 hdmi 2.0 support

[dinker99]

Like a lot of people I`m in the market for a GTX 970.

There seem to be differing opinions as to whether any of the brands offer HDMI 2.0 output. With the imminent arrival of 4K displays I regard this as a crucial feature, has anyone got any information to share?

 

[Pariah]

The only way to know is to check the manufacturer's website for the exact model you are looking to purchase.

 

[Subyman]

Says right on EVGA's website that their 970 has HDMI 2.0.

 

[ShintaiDK]

Problem is manufactors are actually not allowed to show HDMI versions.

With that said, if a GM204 card got HDMI. I am sure it will be HDMI 2.0.

MSI says theirs are 1.4a.

Like I said, check the manufacturers website. Most of them will tell it what version they use.

I'm shocked that not all manufacturers are sticking to HDMI 2.0, which was one of Nvidia's major marketing points for this series.

I'd cross the MSI off the list for that reason alone. The similar Asus Strix has HDMI 2.0: http://www.asus.com/us/Graphics_Cards/STRIXGTX970DC2OC4GD5/specifications/

Also, reviewing the HDMI guidelines linked previously really calls into question the legitimacy of the standard. The prohibition on advertising the version number of an HDMI cable can and does cause mass confusion on the part of consumers due to incompatibilities and poor performance.

I for one spent weeks trouble-shooting a problem with a Blu-Ray player before I realized I was using a "1.2" cable where a "1.3" cable was needed - and of course the cables are not labeled, making trouble-shooting an absolute shot in the dark.

The fact that 1.4 cables, for instance, aren't guaranteed to possess the bandwidth to support 4K 60Hz is going to mean lots of very angry 4K HDTV customers who think their TVs or output devices are broken.

Yea agree. 4k Support over HDMI 2.0 is big, should be in all 970's and should be clear. I wonder if someone at MSI forgot to update the webpage, regardless one to avoid until 2.0 is confirmed.

This type of thing with cable versions can cause head scratching. Had same thing with a Sony Blu Ray player.

Cables people, cables.

You can specify the type of port. Cables are either High Speed(which have been on the market since well before 1.2 came out) and Standard. There's also with and without ethernet channel, but that's not something most are concerned with for this application.

They don't want people specifying version numbers for cables because THEY DON'T MATTER. You'll have uninformed people who had a card with a 1.2 port, who upgrade to a 1.4b or 2.0 port and think they need a "1.4 HDMI cable or "2.0 HDMI cable", both of which DO NOT EXIST. You only need a "high speed" cable....which almost every one sold in the last 4 years is probably high speed.

There's nothing stopping a mfg from listing the type of port. HDMI 2.0 ports don't require a new cable. Just that it's "high speed".

Actually, you are incorrect.

Revisions of the HDMI spec have in fact broken backwards compatibility with older cables. The clearest example was the jump from 1.2 to 1.3: http://www.audioholics.com/hdtv-formats/understanding-difference-hdmi-versions

Furthermore, it's as yet unclear whether the tremendous increase in bandwidth required by 4K/60Hz, only supported by HDMI 2.0, can actually be passed on older cables. Because there have been no devices (up until the release of the GTX 980, as a matter of fact) that could output 4K/60Hz, this issue has not yet been put to the test.

I suspect there will be waves of enthusiasts left scratching their heads as their new $550 GPUs fail to output an image to their 4K HDTVs due to the use of older cables.

Does HDMI 2.0 require new cables?

No, HDMI 2.0 features will work with existing HDMI cables. Higher bandwidth features, such as 4K@50/60 (2160p) video formats, will require existing High Speed HDMI cables (Category 2 cables).

Even these cheap cables should be fine - http://www.amazon.com/AmazonBasics-H...productDetails

I hope you are correct, but just because the HDMI consortium assures us that the millions of existing high-speed cables on the market and in homes will work for HDMI 2.0 does not mean this is actually true. The bandwidth increase is significant, and therefore additional shielding may be required to avoid crosstalk.

Again, the HDMI 2.0 spec simply has not been tested in the field, as there were no HDMI 2.0 output devices until Nvidia's GTX 970/980 arrived.

I hope I am as well

I would think there are many new HDMI 2.0 media boxes (e.x. Roku 4, Apple TV 4, Fire TV 2) that are in the development phase and testing this.

 

[LeonarD26]

For those who are looking at the MSI 970, on their forums they have said it is HDMI 2.0, not 1.4... looking for more confirmation since this is the card I want....

This information seems very hard to find. that`s why I asked here.


EDIT: Found the link for MSI:

4k@60Hz is working on my HU8550 and GTX 980. I'm using a 25ft cable I bought off Amazon:

http://www.amazon.com/AmazonBasics-H...rds=hdmi+cable

Update on the HDMI cable :

On an all-black blackground I noticed I was getting some white sparkly dots on the screen. I swapped my HDMI cable (same brand as I posted above) with a 15ft instead of 25ft. Went away now. Not sure if I had a defective cable or the length was causing an issue - I know some longer DP cables have had similar issues pushing 4K.

 

[Pseudoics]

Any chance Nvidia has Full RGB (0-255) colour space working natively over HDMI for Maxwell? i.e. without reg edits/custom rez

 

[CakeMonster]

Anyone who bought a high end tv this year should be able to test it. I have one myself but I can't justify upgrading my 780 vanilla.

4k@60Hz is working on my HU8550 and GTX 980.

Do you happen to know if it's running at 4:4:4 (no chroma subsampling)? There were some concerns expressed on an Amazon review about the Samsung UN40HU6950 (which does offer HDMI 2.0 support) that it was downsampling the chroma to 4:2:0 even when using HDMI 2.0.

The reviewer (David) suggested testing the following image:
http://s10.postimg.org/wkjtapxll/colors.png

"Make sure it's displaying 1:1 (pixel exact). Browsers may do funny things, so I recommend downloading it and viewing it in an image viewer of some sort where you can click a 1:1 zoom button.
You should see pairs of vertical bars of black, blue, green, red, and then pairs of horizontal bars red, green, blue, black.
Each pair has two halves, offset by one pixel. On a 4:4:4 panel, the lines will come through clear (no blurring between or around the pairs, both halves are the same color, the colored lines are all fully saturated, etc). Very slowly dragging the image around the screen should not result in a "shimmering" effect."

Any chance you could try this on your Samsung TV? I'd be interested to know if the problem exists with HDMI 2.0. (The reviewer tested it with the built-in image viewer on a USB stick, which could have problems of its own.)

That image does not appear to be showing up correctly, the colored vertical lines shift up and down depending on where I move the window.

I'm not sure if it is running in 4:2:0 though, I had a 780 before and when switching 4K/60Hz output the colors looked very washed out in comparison. Now, the colors look the same whether I am running in 1080p or 4K.

I've noticed I can't get the TV to run in PC mode at 4K though. This could be why it is failing that test... without PC mode on at 1080p, I get fuzzy artifacts around the edges of fonts, the same thing is happening at 4K except renaming the input to PC has no effect on the output whatsoever.

I have a 4K tv and 780 (so no HDMI 2.0) and I had problems being able to tell that it ran 4:2:0 until I used a test pattern. It seems to be able to output 60hz which unless I'm mistaken is not possible with HDMI 1.x even with 4:2:0 so I'm not sure what kind of hack it uses for that..?

4K60Hz is possible over HMDI 1.4 with 4:2:0 chroma on Nvidia cards...

[jtw473]

I just got my 980 setup with my 4k Panasonic TV and can confirm that it is working fine at 4k 60hz 4:4:4, using my existing cables.

Thanks, I didn't check my facts there.

I did try and set it down to 24 and 30hz, since I wrongly expected that to be the max even for 4:2:0. However, it outputted the same (reduced) colors at 24hz. I would presume that it should be able to use full color space at that refresh rate which is lower than half of the bandwidth of 60hz?

I kind of wish the NVidia control panel had some more easily available info (or a flat out warning) about color space.

Make sure you set Digital Color Format to RGB under Adjust Desktop Color settings in the NV control panel.
