ghosting question for tech heads

[cmsbfent]

ello..

Basically, i'm thinking of buying a HP Pavilion L2335 23" monitor as i've spotted one for cheap cheap and after reading around, it seems to be a good enough monitor apart from some sparadic reports of ghosting.

Its stated to have a 16ms response time which is alright'ish by todays standards and probably aint too far off my viewsonic 19" tft i have now.

So, question is, with ghosting, does it only really show up with really high frame rates.. i.e., if the refresh rate is locked to 60hz, will the ghosting show. Is ghosting more apparent if running in the 100fps range.

It just seems to me that with a native resolution of 1920 x 1200 or wotever it is, it aint too likely i'll be seeing 100fps, so is ghosting going to be an issue?

Cheers chaps

Ghosting is only aparant if you are susceptible to seeing it.
I have been running 2 x Hercules 920DVI monitors that have a 24ms response time, and I either don't notice ghosting, or ignore it.
The only way to know for certain is to try it out and see if it bothers you.
As for whether ghosting shows more at higher refresh rates, it doesn't really matter because LCD monitors don't use refresh rates in the same way as CRTs. I guess higher refresh rates may show a small amount more ghosting becuase the pixels are having to change colour even more often.

You'll still see it at a lower FPS. Ghosting is just about the screen taking too long to transition from one colour to another. It doesn't really matter what framerate your game is running, the screen contents still change and your monitor will still have to do colour transitions all the time, and if it's not doing them quick enough then you get ghosting. At a lower FPS the screen contents may only change 20 times per second, but if the transitions aren't complete within the screens sync period (1/60th of a second) then you still get incomplete frames where the picture is not 100% finished. Also at a lower FPS the distance things move in one game frame will be higher so you could see more ghosting but less often.

It shouldn't be 'bad' on a 16 ms (ISO) screen though.

Still amazes me some people can't see it, it's a very obvious effect, even on an 8 ms screen. It's there on every moving thing on the screen to some extent. Every time you move the mouse in an FPS game, the whole screen 'dulls' just a little and everything loses focus. If you strafe from side to side and watch the ground, or a close-up wall, you can see the textures become blurry. When you compare side by side with a CRT it's just so obvious.

It's not too hard to just play your game and forget about it though. Imagine it's the game doing motion blur
