Flat panel and the refresh rate settings?

[LastBoyScout]

Hi all,

I have temporarily connected a flat panel Sony sdm-s94 to my graphics card. I am used to a crt and I use it with 120hz. Of course now I can only choose 60hz. However the mouse move quite strange and if I switch off "show only supported modes" and I choose 120hz the mouse moves as expected (why does this depend on vertical hz?).
In the onscreen menu of the flat panel it shows up as only 75hz. I'd like to continue with 120hz because of the mouse... will it hurt my flat panel?

thx

I'm almost 100% sure it wont hurt the panel. My VP191s has a maximum of 75Hz, but I overclocked it to 79Hz with Powerstrip.

When I increase to 80Hz, the panel says not supported.

If I choose more than the allowed (100Hz for example), it will always stay at 75Hz.

All the new flat panels support 75Hz.

Actually it does matter, but not because of the liquid crystal itself...the drivers controlling the TFT portion simply can't go that fast.

You gotta remember, 60 Hz means the drivers have to deliver 60 screens' worth of information every second. There's 3*1280*1024 sub-pixels on a 19" LCD, and (assume) each has 8 bits. That's about 31 MB. 60 Hz means 60 times that, so that's 1.9 GB/s of information transfer. 75 Hz is 2.4 GB/s of information transfer. Much more than that and the monitor doesn't want to risk giving its drivers a headache so it'll poop out and say "out of range" or something like that. It's all the same to the liquid crystals, but the other stuff mind if you try to make them go too fast.

But it shouldn't hurt to try. Far as I know, LCD monitors all have built-in things to make sure the user doesn't do something stupid. I think.
