For HDMI you need v1.4b equipment. This supports 3D at 60 fps per eye. Unfortunately the Radeon HD 7950 only has HDMI version 1.4a. Basically your videocard and display need to have HDMI version 1.4b ports for 3D 60 fps per eye. My tv Panasonic tx-p50vt20 only has HDMI v1.4 ports. I'm not sure of TVs and videocards that support v1.4b HDMI ports. Hope this helps you understand the HDMI versions. You also need to use a high speed HDMI cable. Most cables are as 1080p60 2D mode needs a high speed HDMI cable.


HDMI v1.4
HDMI v1.4a
HDMI v1.4b standard released mid 2011.
HDMI v2 2013

Small edit here I looked at the White Paper 'AMD RADEON™ HD 7900 AMD RADEON™ H D 7800 AMD RADEON™ H D 7 700 SERIES GRAPHICS DISPLAY TECHNOLOGIES' white paper. It mentions on pg.14 : -
'HDMI® Stereo 3D Packed Frame
The HDMI® 1.4a specification provides a method to support Stereo 3D display
devices. This specification provides a mechanism for the source device, in
this case the GPU, to convey frame polarity information, while maintaining full
resolution. The majority of stereo 3D TVs released in the market since 2009 support
the HDMI® 1.4a specification. Today, monitors support stereo 3D through HDMI®.'


'The first mode listed above (1920x1080 @ 60Hz/Ey'e) is very critical to gamers who want to play games
in stereo 3D. With the 3GHz HDMI® speed supported by the Radeon™ HD 7700-7900 Series GPUs,
higher frame rates (up to 60Hz/Eye) at Full HD resolution can now be transmitted to the display device
resulting in smooth and responsive game-play. Another feature enabled by 3GHz HDMI® speed is
support for 4kx2k resolutions, which will be discussed later.'



So on my Radeon HD 7950 somehow AMD are passing 1080P 60 fps per eye 3D over HDMI 1.4a. Now it's question of finding a 50-60 inch TV to handle it at the right price...

I wish I could test it! This sounds so unlogical. There is no scaling involved in 720p I think? It has same aspect ratio like 1080p. Just set your resolution at it and play your game. Why else do other systems like PS3 use 720p for 3D?

I really cant think a reason why stretching 960 to 1920 would be superior to true 1280.

Thanks for your arguments though.

Hi again

if your TVs panel is only 720P I guess you would be correct.

but the majority (all?) of new 3D TVs are actually natively 1080p panels, so ideally you do not want to be running at 720p as the TV then has to scale the image up to match your tv (unless you want to play in a little window with a giant border all round your screen), and some TV's scalers are better than others)
systems like the ps3 use 720p for 3D becasue they are based on 7 year old hardware and do not have the power to run at higher resolution with decent eye candy (higher the resolution the more work it is for the hardware) (even the "next gen" consoles are struggling to hit 1080p at decent framerates)

**but I am no pro and would also love to hear Gregs thoughts, but he may be busy so you get my waffle again :)

No idea yet, But if you do get the Tv and it has the 2D to 3D conversion, the Capital Ship video looks pretty good.

Only last night my Son's new 3D TV was delivered which has 2D to 3D conversion on it, we looked at a couple of 3D movies first and I was blown away, you could almost touch things floating in the room, it was far better then anything we've seen at a cinema.

As soon as my Son left the room I was straight there to test the Capital Ship video, and yes I can confirm it looked pretty cool. sadly my Son has now taken his 55" 3D TV upstairs :( still, I have my PC connected to my 50" it's not 3D but sure it will be cool :cool:

LOL thats not how I meant :) I just noticed he reads this thread too. Your posts gives me food for thought :)

I do own a full 1080p 3D projector actually. But I can't stand watching any game (or movie even) in 3D at 24hz. So I am stuck at 60hz.

I somehow convinced myself 'real' 1280 is better then doubled 960. Maybe I should try again but right now my projector is in a box even :S (too busy with reallife lately to watch any movies)

Your right PS3 is ancient. PS4 might be better.

Since your the pro here could you shine why its preferred using Half Side by Side 960x1080 over framepacked 720p 3D?

I'd love to say it was some deep thought out reason, however it was just quicker to code up side by side (and we needed it in that mode for Oculus Rift). If there is demand for 3D (it seems a love/hate thing), we can look at investing time supporting the other modes.

Quickly checking, my Samsung monitor says it supports side-side, top-bottom and framepacked - so I can try out most of the standard modes.

If 3d is available during the alpha I will try it out on my Samsung TV and will provide feedback. I think it can do all 3 options although I have only used it for side by side if not using a blu ray (because that's what sky do unless I am mistaken).

Would love some feedback from people on how 3D looks/works.

I'm planning to buy a new TV for ED in Jan anyway so if 3D is well recommended then it'd be rude not to go the whole hog


This game is getting more expensive by the day :D

+1 from me, look into the 3D mode. Is this worth a survey to scope interest?

Hmmm I don't like to be demanding but if you could do frame-packed 1080P 60Hz per eye that would be great...I think there are more 3D TV owners than OR owners

Thats the problem actually. HDMI 1.4 TV's and projectors support 1080p 3D only at 24hz. Thats why people resort to SBS or 720p 3D at 60hz.

It's an HDMI limit and so the developers of games cant do anything about.

If you read my post above there are 3 versions HDMI v1.4, HDMI v1.4a and HDMI v1.4b.:) If you want to play at 1080P 60Hz per eye you need HDMI v1.4b videocard and 3D TV. HDMI v1.4 is the very first HDMI version to support 3D but is also the oldest. HDMI v1.4b came out third quarter 2011.

Hope that clears it up.

I would very much like this.

Occulus Rift is a bit OTT for me (plus the motion sickness thing...) however I have a 3D TV (SBS is fine), so if the game supported it this would be a fantastic unexpected bonus. :)

Oh wow 3D! I have a 3D 42" LG monitor/TV 1080p and a Radeon R9 290 4GB
I really hope to play ED in 3D with no lag!
Watch bits of pirate debris pop out of the screen .. awsome!:D

Question is will the game support it (out of the box) or will I have to install seperate software to do the SBS image?

I think since people generally have access to it I think it gonna jump up the demand queue. I think nobody really though about it as it's never been big in gaming...
