I need some help, I have got a Samsung LCD TV which is 200hz. Does that mean the PC's HDMI out should be able to display at that refresh rate??
I connected my HTPC to the TV via HDMI and it picked it up at 1080p, but at 60hz. Can i raise this higher?? 60hz is the highest in NVIDIA CP.
I read on the net differnt posts which are similar to this subject and they say that 60hz is highest it will go from the Graphics card. Is that correct??
I have a nvidia 9300 tyied to a 9400 using hybrid sli and use HDMI from this to TV. What I need to know are there cards which display higher refresh rates?? Is 60hz the highest i can use?
Although both HDMI and DVI are capable of transmitting signals above 60Hz, they are bandwidth limited. 1920x1200 120Hz is the max for dual-link DVI for example. At lower resolutions, you can get to higher refresh rates. Of course, the TV would have to accept a 200Hz input in order for this to work - most advertised TVs that are >60Hz cannot actually accept an input of higher than 60Hz, they just interpolate the intermediate frames to get to 200Hz.

I hope I may be excused for asking a question in a thread created by someone else, for it relates to the discussion here and I judged it better to ask here rather than create a distinct thread.
Anyways, I have a 24" monitor connected to a 8500gt by a DVI-I cable. The recommended settings are 1920x1200/60Hz as is typical, but I can only select 59Hz from the Nvidia control panel. Is this a bandwidth limitation? Would 60Hz be supported by a DisplayPort input? Can this irregularity make any noticeable impact on smoothness, especially in a 3d game with V-Sync enabled?
I am running Windows 7 RC Build 7100, if that bears on this question.
@ bodgeup,
Either go to a dedicated shop and tell what you are after or check on the Internet, I know there are HDMI cables rated at both 60Hz and 120Hz, i have seen adverts for cables that support 200Hz sets but supporting and actually supplying 200Hz is a different thing all together
The TV i am trying this with is a Samsung 8 series 40" LED TV 200hz.
Dont suppose anyone knows if this TV can support over 60hz in via HDMI/DVI??
Also if it did support higher values would the Graphics card sutomaticaly detect the available refresh rates or would it be down to the graphics cards specs??
ie. will a low end Nvidia 9400 be able to run over 60hz 1920x1080? The specs for graphics cards dont really say the just say it supports 1080p HDTV thats it.
