Hi.

I recently bought samsung real 120hz input monitor, syncmaster S23A950.

So I want to see 120hz at just normal 2d game and normal web-surfing for better eye strain.

But my laptop (vaio, geforce gt540m) does not seems support 120hz output.

I connected from my laptop's hdmi output -> hdmi<->dvi-d(dual link dvi) adaptor -> dvi-d cable -> monitor.

But I saw 60hz is maximum at control panel-display-screen resolution-advanced-monitor tab-refresh rate setting.


So my question is,

what graphic card do I need to support 120hz output? I prefer radeon on this monitor because this monitor does not support nvidia's 3d vision ready. And using tridef 3d, and support radeon's hd3d feature.

so over radeon 6000 series all support 120 hz?

or if go to geforce, what series support 120hz?

Thanks.

I'm not going through that entire manual, but you do realize that to display 3D, you must have a 3D source to display. Either a 3D DVD player, one AMD's software options or 3D vision. It doesn't convert 2D movies into 3D.

This is the diffrence between technician and technologist.

Page 25, you has to activate 3D mode
- 2D to 3D: Converts a normal video to 3D video.
- Frame Sequential: Display the left and right images alternately in each frame.
- Top-Bottom: Display the top and bottom images overlapping each other to allow you to experience the 3D effect.
- Side-By-Side: Display the left and right images overlapping each other to allow you to experience the 3D effect.

You can also input real 3d images.



Install your monitor driver and try to set it to 120Hz!

hi there.

Please read my question only...

Please don't assume on your own...

Of course already I know my laptops can't do.

I think to buy desktop graphic card of course.

You never mentioned ANYTHING about a desktop. Did you think we are all psychic mindreaders??

I did answer the question, to use 120hz at 1080p (@ 720p and below you have more options), you will need a card that has a dual link DVI or displayport connection. As far as I am aware, all new cards support this, except a few rare exceptions. Just look at the picture, if it doesn't have displayport of dvi, it won't work.

1st off, he isn't looking to do 3D. All forms of 3D you listed, except 1, requires a 3D input, which involves software, either on a DVD player or computer. Have you ever seen this 2D to 3D converter? I'm curious, as logically, there is no way this can be done effectively.

You can't just plug in the monitor for 120hz if you are playing at 1080p, you do have to have the right cable and connections available, his laptop currently doesn't.

I am curious about that 2D-3D conversion. I don't know how you can convert a 2D image into 3D image without knowing a lot of info not given. I am curious how the software (software on the display) makes it into a 3D image with any accuracy.

Thanks.
So it means, graphic card's spec does not matter for 2d web-surfing 120hz?


Because I now using this laptop my main computer. So I firstly tested with this. and already I wrote got failed with this.

And then, I questioned about graphic card's spec or requirement for 120hz.

Was I be seemed so pool or noob even don't know laptop's graphic card can't be upgraded?

In a nutshell...

You cannot upgrade the video card in most laptops (at least 98% of them). Laptops that may allow you to upgrade the video card are gaming enthusiat laptops that generally costs at least $1,500. Only a few of them allows you to upgrade.

In order for a 120Hz monitor be capable of refreshing at 120Hz (instead of 60Hz), your video card must have a dual-linked DVI port (each DVI operates at 60Hz). I am not very familiar with HDMI specifications, but I think only HDMI 1.4 and above ports can output at 120Hz. If you have any of the older HDMI 1.3 (a,b,c...) then you are stuck with 60Hz output.

The nVidia GT 540M does not support 120Hz. You either need to buy a laptop with a powerful video card that can support 120Hz output (if one exists) or build a desktop PC and choose a video that is powerful enough to push over 60FPS at 1920x1080 resolution.

The nVidia GT 540M is a relatively weak video card so trying to play a game on a 1920x1080 monitor will not be stellar. You also need to realize that some performance will be lost using an external monitor since the video card must also refresh the laptop's screen.

As I mentioned in my first post, you cannot convert a dual link DVI signal to an HDMI signal and maintain 120hz with HDMI. HDMI has a limit of 60hz at 1080p. If your laptop has a DVI or a displayport connection, then you could, but I doubt it has one, as that's quite rare for laptops.

The newest versions of HDMI (at least 1.4) do allow for 120hz, but at a maximum resolution of 720p.

EDIT: I think I was wrong there. The way it's listed, I don't think HDMI can go above 60hz, but it has a special dual signal packet method to allow 720p to send two signals at once, allowing for 60hz 3D images (which is similar to 120hz).

Currenly my desktop's graphic card is very old one, and it does not have any of those port.
