Help with Refresh Rate

Last response: in Graphics & Displays
Share

I just recently got a Samsung 58" Plasma.I know the refresh rate is 600hz but when i plug my computer into it it says the max reported is 75hz.I figured it would be able to do 120hz at the least but it's not working.60mhz seems to be the max.I've tryed both HDMI cable and VGA cable but neither will do more than 60hz.
Using a XFX6870.

Does anyone know how to use more than 60hz?

Could it be the HDMI cable?

The refresh rate being 600Hz is absolute marketing bullshit. The highest TV rates I've seen is 240Hz, but the problem?
The input is NOT 120Hz or 240Hz, you are still stuck with HDMI most of the time which gives you 60Hz input, then a chip on the TV "guesses" and adds frames in.
Some of the High refresh rate TVs do support 120Hz input.

Please give us the exact model, I do honestly believe Samsung is not stupid enough to advertise 600Hz.

No, not the cable company, HDMI itself is rather bloated and no better than a Single-link DVI, which is basically 12 year old tech.

Bottom line: You need a dual link DVI or DisplayPort in, HDMI can't do it.

It mentions "600Hz Subfield Motion Refresh Rate", that means the TV is divided into 10 60Hz zones, and the zones refresh asynchronously (not at the same time), so with Samsung logic, 10 * 60 = 600.
So basically it's even more of a gimmick than 120/240Hz LCD's.

1. HDMI does not support the input (HDMI 1.4 might, not sure what your TV has)
2. Your TV is not actually 600Hz in the monitor sense of Hz.

DisplayPort is a specific connector type, http://en.wikipedia.org/wiki/DisplayPort
It is considered NextGen (unlike HDMI) due to it's higher bandwidth.

Your Computer cannot send anything more than a 60Hz display because the CONNECTION does not support it.

You are basically saying, I have a 4-lane highway, I just added another road to lead on to it, now it should become a 8-lane highway.

Under "Inputs and Outputs" I see:
4 HDMI Inputs
2 Component Inputs
1 Composite (AV) Input
1 PC Input (D-sub)
1 PC Audio Input (Mini Jack)
1 Ethernet Port
1 Optical Digital Audio Output
1 DVI Audio Input (Mini Jack)
1 RF Input

So no DisplayPort.

Here:

So no matter what you can't get higher than 60Hz.
