Help plz with HD 7950 and 3D

[techx]

hi all,
im planning to buy SAPPHIRE HD 7950 3GB OC GDDR5
here the link
http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&pid=1450&psn&lid=1&leg=0
and I have monitor Samsung S23A700D
and this link for monitor
http://www.samsung.com/africa_en/consumer/pc-peripherals-printer/monitors/led/LS23A700DS/XA
my question is
Is this card support this monitor with 3D @120Hz??

and thx all

It will, but not at 1080p with 60hz (per eye).

You should look at the Samsung 750 or 950 models for the displayport connection required for AMD to support 1080p HD3D at 60hz.

Unless AMD has added support for dual-link DVI, but last I have checked, AMD required frame packing that is not supported by DVI.

EDIT: I noticed that the link you provided for the video card specifically mentions that the HDMI and displayports support stereoscopic 3D, and the DVI connection does not. This means that monitor will not work for you at 1080p assuming it even allows for HDMI 3D.

at video card link it say:
Dual-Link DVI:
Equipped with the most popular Dual Link DVI (Digital Visual Interface), this card is able to display ultra high resolutions of up to 2560 x 1600 at 60Hz.

so maybe at 1920 x 1080 i get 120Hz??

Yah, you can use 120hz with that at 1080p, but not 3D. HD3D will require either HDMI 1.4a or Displayport.

 

[techx]

the monitor dont have displayport
so at HDMI 1.4a I get 120Hz or 60Hz or what?

With HDMI 1.4a with the use of frame packing, you can get 60hz per eye at 720p or up to 30hz per eye at 1080p. It will not work at 120hz without 3D.

Why don't you buy an Nvidia card? I'm sure it supports 3D through DVI.

 

[techx]

nvidia doesn't support this monitor
I see this in my monitor manual

so whats u think guys?

 

[bystander]

I don't know. According to your video card, and AMD a few months ago at least, AMD won't work with DVI-D with HD3D. Maybe things changed? I don't know.

 

[bystander]

Maybe Samsung has its own software to make it work.

 

[techx]

ok, what u advice me guys?
what video card I should buy with my monitor (Samsung S23A700D)
HD 7950 or something else?

I'm lost QQ
help me plz

 

[Sunius]

I'd email AMD and ask them if it's going to work.

 

[gamerkila57]

ok your monitor has an HDMI port so all you have to do is plug in an HDMI cable and download TriDef 3D. Also 3D will work with DvI so you'll be fine ?

 

[djscribbles]

You're kinda out of luck, if you already own the monitor. You can do 24fps over HDMI, but otherwise you bought the wrong monitor. It's kinda sad that samsung sells that thing, I've seen a few other people land in the same situation.

Though DualLink-DVI is worth a try and may actually work, seems to be pretty conflicting information. It does have the bandwidth to support the framerate needed, but it may not be supported for frame-sequential 3d in tridef.

On the upside, you should be able to keep a steady framerate, if you are capped at 24fps. I have a 7870, an i7 2700k, and s23a750d, and some games have trouble reaching 120fps in 3d in some games (looking at you skyrim).

Nvidia isn't going to be any better. They require you to use their glasses and monitors to get frame-sequential mode.

(sorry for all the edits.)

 

[techx]

ok ty all
the problem in the monitor or in video card? :/

 

[djscribbles]

If there is a problem, it's going to be the monitor. HDMI cannot support full framerate 3d.

DL-DVI does support full framerate 3d (bandwidth wise), however it's questionable whether it's supported by AMD for Framesequential 3d.

Your monitor isn't an Nvidia 3d-vision monitor, so your best case scenario in using an Nvidia card would by side-by-side 3d mode with tridef, which halves the resolution of the composed 3d image.

If you want to know before you buy, contact AMD directly and ask "Will an HD 7950 support frame sequential AMD HD3d at 120Hz (60FPS per eye) over dual link DVI?".

If you have an AMD HD 5000 or newer video card and a dual link DVI cable, you can test this yourself using the trial version of Tridef, and see what framerate you get (note that tridef displays your framerate as fps per eye, so 60 fps means you're getting 60 left eye frames and 60 right eye frames); choose an older supported game with low cpu and gpu requirements and run at low settings so you can ensure it's maxing out framerate.

If you need a new video card anyway, AMD is going to give you the best results given the monitor you already own. The 7950 is a good choice, going for the 7970 however would not be a waste either though, I rather wish I had gotten a stronger GPU than the 7870 when I purchased.

yes HD3D works with all DVI as DVI is the same as HDMI but doesn't support High-def audio ? you'll be fine ? i use DVI now for 3D ?


if you read this it says to use 3D you need either DVI out, HDMI, or Displayport ?

[techx]

ok sry for asking a lot

is 7970 will do better than 7950?
so best choice is 7970 then 7950?

 

[Sunius]

Yes hd 7970 is faster than hd 7950.

 

[gamerkila57]

if gaming either will be fine ? you could oc an HD 7950 to compete with an GTX 680 ?

 

[techx]

I mean 7970 will do better than 7950 sequential AMD HD3d at 120Hz? (not in game, coz I know it's better for game)

thx

 

[gamerkila57]

are you trying to game in 3D or watch movies like i do ?

 

[techx]

both
but 7950 is enough for me for my games
no big difference in FPS between them but big difference in $
so ill get 7950 OC
but idk about 120Hz xD
and sry for my english

 

[gamerkila57]

well just get the HD 7950 and oc it and you will be good to go especially with that monitor ?

 

[techx]

OK
i'll get 7950 OCed
I think this is best choice for me
7970 is waste for my $

thx all for help
