refresh rate question

[tcos]

didn't know if I should be posting this here or video card section exscuse me if I messed up. Anyway my question is this I noticed in my nvidia control panel I could only get a refresh rate of 60hz. my sony lcd has a refresh rate of 120hz. I tried to use the customize with no luck. I get a failed error. But I also get a failed error at the 60htz.Just curious. Thanks for reading.

REFRESH RATE does not apply to LCD monitors

They use RESPONSE TIME

And are locked at 60hz which means you will only get 60fps while the rest are dropped.

From what I understand 120Hz TV's are able to use 24fps (refreshed 5 times to make 120hz). I don't know much more than that but I hope it gives you something to go on. I'm assuming there is something more to it that I'm unaware of since IMO 24fps seems piss poor.

The 120hz on TVs IS NOT true 120Hz. The LCD TVs that are advertising 120Hz are actually using interpolation (inserting a signle frame between two actual frames) to achieve 120Hz. Therefore, the input refresh rate stays at 60Hz but the TV converts it.

unless it's a blu-ray of course :D

The source material has nothing to do with it in this case. Current HDMI standards just don't have the bandwidth to transmit a true 120Hz signal. HDMI 1.3 should have enough bandwidth but that is still some time away.

ummm, HDMI 1.3a is already out. My projector and receiver are both HDMI 1.3

Sorry, I think I need to clarify.

The issue is that all of the "120hz" TVs being sold now in the sub-$2000 category lack the proper technology needed for true 120Hz operation. Supposedly actual 120Hz 32"+ panels are still about a year away.

so basically you get what you pay for then

Yes and no. I can spend $4000 on and LCD TV and it still won't display a true 120Hz picture.
