View Full Version : LCD Monitors and refresh rate

How does refresh rate affect eye strain with LCD monitors?
On a crt monitor, a low refresh rate can cause eye strain, and even trigger bouts of depression, due to the vertical scanning that a CRT displays with.
With an LCD, does refresh rate affect anything except for 'motion blur' (such as on a mouse)?

Whole Idea of LCD is that it is not dependent on refresh rates.
here is a cool link to get an idea of how lcd works,

I think the only real problem with LCD is ghosting, dimness, and view angle. At school, we work on these sweet 23in. Apple Cinema displays, and they're gorgeous. At home, I work on a Samsung SyncMaster 900NF and its gorgeous as well. The only thing with LCD is that you have to look dead on or it'll lose color and brightness. Other than that, a good quality LCD can be awesome for applications, but be wary of them for playing games. I still don't feel like LCD provide the best gaming experience. It all really depends on what you want to do I guess.

the reason i asked is that my computer broke while bringing it home from college. i tried everything in my power to save it, but no.
i'm going to replace it with a laptop (much better for traveling 1800 miles).
right now i'm leaning towards a Hypersonic PC Sonic Aviator laptop with the new 3.06ghz P4 with HyperThreading, 512mb DDR ram, the Radeon Mobility 9000 128mb, etc etc, and the new UXGA 15" lcd (1600x1200 native).
to save battery power, the radeon actively disables and enables features as they are needed. when unlpugged, the radeon lowers the refresh rate of the lcd.
anyways, as long as my eyes don't fall out using this thing, i'm golden.

As Ckerr812 pointed out - LCD doesn't have a refesh rate... So that's a little odd!

I think in that case, it would be how often the LCD is updated so you could get some slightly choppy playback perhaps? I'm not sure.

LCDs do not flicker due to limitations in how fast the pixles can change what they are displaying.
LCDs work fine with games, I think.
As for the graphics card conserving power; that is the least of your worries. The graphics gard will draw nothing compaired to that desktop P4. Also, don't plan on using this thing on your lap because desktop P4's put out too much heat for this.

Refresh rates are nothing to be worried about, all you have to do is run at your optimal resolution (mine being 1024x768) and leave the refresh rate at 60hz. If you use non-optimal resolutions you will experience crappy blurring etc... The thing you SHOULD worry about is response time... sadly my LCD monitor is a few years old (NEC MultiSynC LCD1530V) its really sharp and good colours and all for an LCD, even nice viewing angle, but sadly its response time is somewhere very high hehe.. ghosting and trailing etc... SUCKS :( It's really nice when its stationary or small animations that arent 'fast' but in fast action it gets blurry trailed :( Today's best response time is something like 16ms, mine i suppose is like 45ms maybe even higher lol.. horrible :( however I've used it for so long that I forget about it heh... sometimes it gets on my nerves though.. but cant afford anything better and don't wish to go to the radioactive blurry CRT :P

Tell me, what do you get blured streaks on, games, animation? Could you show me, because I have the exact model of NEC monitor you mentioned (actually I have two) and never had a problem.
I play games the odd time, and play animation and dvd's on them all the time. Never had a problem? You make sure to install the drivers for the monitor, I noticed that made a huge difference for colour correction and viewing angles.
I have never ever experianced anything like blurring, but maybe I am not looking hard enough.

I am a hardliner critique and if you were to truly ask me to critique something I'd make you cry and commit suicide sorta deal.. anyways lol the slightest misdetail anoys me.. and well honestly I think this is a big issue not just a little insignificant detail... I dunno how you can not notice it :/ Maybe you have some of the later 15xx models, those have better response time. What drivers do you use, maybe it was the colour profile schemes, etc.. etc.. that you mean? I have custom built drivers :P Shouldn't really matter, the info is read from the monitor thanks to the EDID standard and the monitor self adjusts itself to optimal settings. The blur and ghosting even when you scroll a webpage should be obvious like a delay in rendering. The same goes for the mouse it creates a trail. In games and movies in fast action based motion its very scary and bothersome...

Yea, Sorry sport, have no idea what you are talking about. I have had mine for about 3 years or more now..so I am guessing it is the older model, with nothing like you explained there. I am a stickler for certain things, and ghosting would make me wanna take the monitor back the day I bought it.
I run Quadro2 on one and Quadro FX on the other, but at work I use trintitron sony monitors so I would notice a difference I am guessing.
Again though, the drivers make a big difference, the nvidia and the NEC drivers.
