Forcing higher "refresh rates"

[josh6079]

I was just thinking, if my vsync is on in games and normally bounces around 60, could/should I force a higher refesh rate in my CCC so that it bounces around 75 in games. That way when it would start working harder it would go into the 50 and 40 area rather than the 20 and 30.

Refresh rate won't affect game performance at all. There's no reason to increase it with an LCD though...

Really? But I thought that the vsync maximizes your game's frames by the refresh rate of your monitor. If that is the case, then wouldn't a higher refresh rate mark a higher limit (frames per second) with a game's vsync?

Yep, it would. The motion would also be smoother, on any display device.

Cool, would it be safe? I've got the the Dell 20"widescreen (not the new one) and all other specs in my sig. Would it ruin the monitor or something?

If you're running vsync then you should also use triple buffering.

As for your refresh rate, I'd run it as high as possible on an LCD given I can't see any reason for it to damage anything.

I don't think it would damage it. If you can force 75 go for it.

You won't notice any difference between 60hx and 75hz on an LCD. And, unless you can tell the difference between 60fps and 75 fps in games, you don't be able to tell there either.

Some cheaper LCDs will actually blur noticeably if you force a 75hz refresh rate.

Why not? I sure do. I run 75 Hz all the time, and I will always make sure an LCD I buy supports at least 75 Hz. It feels a lot smoother to me. (OK, I'll be honest, I'd get the 20WMGX2 even if it only supported 60 Hz. )

Yup, that is true, although expensive ones like the Samsung 970P also have the problem of lacking a decent look-up table for certain resolutions, and the overdrive functions suffer a bit. Besides that, the blurring will automatically be more noticeable at higher refresh rates.

"They" say higher refresh rates could damage LCDs, but I've been using 75 Hz for years without a problem. I don't believe it would damage them anymore than it would "damage" CRTs. It is certainly within spec for some. Unfortunately for the OP his LCD only goes to 60 Hz, at least with DVI, AFAIK. He may be able to push it farther with VGA, but that's in the "out of spec" territory so I can't comment on damage there. Pushing CRTs too far garbles the image completely (and probably instigates wear and tear on other components), but I'm not sure what it does to LCDs. Last time I tried doing that I think I got a couple horizontal bars across the screen. (Hey, if you never try it, you'll never know what it does. )

You could also try flashing your monitor's EDID (flash firmware) with higher refresh rates. I did that to try to get my HDTV tuner to connect up to my monitor (though that failed). I didn't damage any components though. But it's just like overclocking. It's gonna void the warranty. In my case I was flashing the EDID just to get advertised features and a resolution/refresh rate it was supposed to support, so that's a little safer.

If you run it too high you get this little message that says "OUT OF RANGE" so just run it as high as you can until it gets "OUT OF RANGE".

PowerStrip bypasses that though.
