Refresh rate

[nicoliani]

I have read that DVI only can handle 60Hz refresh rate. But there is users that can run at 75Hz with DVI, so how is this explained?
What about HDMI, is that too regulated to 60Hz or does it go above 60Hz? If yes is it up to the cable or input/output of LCD and graphic card? What I mean can I get over 60Hz with a HDMI cable with adapters for DVI on my LCD monitor?

If I am not mistaken what you are referring to, the refresh rate the cable/port can deliver and LCD/CRT monitor can output are 2 different things. If the DVI/HDMI is set at 1080p60, that means 1920x1080 resolution at 60 frame/sec or 60Hz, while LCD/CRT monitor can take those information and display at much higher rate like the new top of line 52 inch Sharp LCD TV at 120Hz.

Within the next couple years, the video source (ie blue-ray and HD DVD players) will come out with capable of outputing 120Mhz (120 frames/sec) while the content 1920x1080p24 on the blue-ray or HD DVD disc remains the same. This will eliminate the problems of 3:2 pull problem commonly associate with current DVD players. If I remember correctly, Hollywood movie is filmed at 1920x1080p24 while the TV studio video is film at 1920x1080p30, so finding a common denominator such as 120Mhz will eliminate much of output problem. Combining with a large screen TV capable of accepting and outputing 120Mhz signals (rather than the current only outputing 120Mhz on screen) that will be the new standard.

when people claim they are doing it at 75hz they don't know what they are doing because apparently that makes it skip 1 of every 5 frames or something so it's pointless.

I would like to find out definitively. I assumed the 60Hz limit only applied when the bandwidth was maxed out at the top resolution.
On the other hand I have heard mentioned quite a few times that frames are skipped which I would assume keeps the utilised bandwidth the same regardless of refresh rate.
This shouldnt be necessary unless the display hardware really does lock to 60Hz regardless of whats thrown at it.

If thats true then VGA/Component rules!
Sadly (fortunately?) I havent got any digital connections in my house to test with.
