Is a faster monitor refresh rate better than a slower one?

Is a faster monitor refresh rate better than a slower one?

I'm just after performance, increase my fps in games - nothing more.

Many thanks.

Answer
For FPS in games it is going to make no difference.


For usage, it depends.

You need a fast enough refresh rate that the screen will not flicker. For LCDs that is 60 Hz. For CRTs most people are happy at 75 Hz. Some need to run at 85 Hz.

You also want as low a refresh rate as possible. The electronics in the video card and the monitor have a limited slew rate - the time taken to change the voltage from one level to another level - So the shorter the pixel time the higher percentage of time that the electronics spends changing the voltage level and the shorter the time actually spent at the correct level. Higher vertical refresh rates or resolutions mean higher horizontal scan rates which means shorter pixel times.

The problems seen due to this is jitter in LCD monitors, and dim vertical lines and blurring of the image in CRT monitors.


Set LCDs to a 60 Hz refresh rate, and CRTs to 75 Hz. If you can still perceive flicker on the CRT when looking off to one side then up the refresh rate to 85 Hz.

Monitor Refresh Rate?

So I was playing DMC 4, and didn't notice that the refresh rate was defaulted to 75 hz. My monitor supports no higher than 60 hz ( am using an LG W2252TQ). Since I am hooked up DVI-D, the refresh rate was forced anyway. I noticed the game was really straining my eyes, so I turned the refresh rate down to 60 hz. However, I still feel like the monitor is straining my eyes.

I had heard that setting your refresh rate too high could damage the monitor. Do you think I'm suddenly feeling this now because I damaged something, or am I probably just obsessing over it? Also, COULD that really damage the monitor? Thanks.
Also, I was only running DMC on 75hz for 5-10 minutes max.
So far the answers are good. However, I have had this monitor for a while and it has never strained my eyes until now, and I am in front of it about four hours daily. Also, in Windows, if I check "Hide modes that this monitor cannot display" it goes up to 60 hz maximum.

Answer
You should be fine.

If the monitor is LCD, you'll have a tough time 'damaging' it by playing around with refresh rate settings.

When i play certain games my pc monitor turns to standby?

Q. If I play cerrtain games it happens and when I press a button nothing happens but the pc is still on. Does it have something to do with refresh rate or resolution?

Answer
you could go to desktop properties and change the monitor which is probably 75 hz to 60 instead

Which is better? Hp mx703 CRT Monitor or Hp 1502 LCD Monitor?

Q. I have a Hp mx703 CRT Monitor and Hp 1502 LCD Monitor and I want to know which one is better in gaming and everyday use. Thanks in replies

Answer
As I mentioned in your other question, that monitor can do up to 1280x1024 @ 60 Hz. It can also multisync to 1152x864 @ 75 Hz, or 1024x768 @ 60, 75 or 85 Hz.
The LCD has a native resolution of 1024x768 @ 60 Hz.
The CRT has a larger screen than that 15" LCD as well.
The LCD is a slightly older model, and as such probably has a response time, viewing angle, and contrast that is lower than that of newer LCDs. CRT monitors have excellent response time and very deep contrast as well as great color fidelity, better than any LCD.
CRTs are popular among gamers because of their very fast response times: no motion blur or lag. They are also very popular among video editors and the printing industry because of their great contrast and color.

Go with the CRT.

What should I do to prevent burn in on my plasma?

gaming monitor 75 hz image

I recently bought this.

http://www.samsung.com/us/video/tvs/PN60E530A3FXZA

I also have a new computer so I decided to make the tv my new monitor.

I am worried about the tool bar burning. What can I do to prevent this?

Also I read that this tv is 600 htz however it says the max it has preformed is around 75 htz is there anyway I can get it to 600?

Answer
OLED >=< Plasma > LED (aka a LCD tv with LED backlights) > LCD.

First you should know that ALL types of tv have burn in.
- Second I will only explain plasma tv's. Newer plasma tv's fixed their possibility of getting burn in by using pixel shifting. You should know that plasma tv burn in is NOT permanent. Plasma tv's have a setting/option to put on a moving image like fuzz to unstuck stuck pixels (if it does not have that option you can do it yourself) and you should know that pixel shifting will unstuck any stuck pixels too.
= Plasma tv's actually have no burn in problems = best.
= Burn in on plasma tv's is caused when you leave a still (non moving) static image on the the screen for long periods of time = don't use letterboxing/black bars or leave other non moving images on the tv for long periods of time.

FPS = frames per second (of a video).
- Frame rate is how many individual images are displayed in a second. Think of a video as a fast moving flip book.
- NTSC tv broadcasting countries use 30p or 60i fps. or PAL tv broadcasting countries use 24p/25p or 50i fps. Movies for most/all countries use 24p fps, movies are soon to be up to 48p fps (tv may have a cinematic effect which doubles the fps of a video).

Hz = refresh rate (of a tv).
- Example: A tv with a 120hz refresh rate, meaning it refreshes the entire tv screen 120 times a second. Read the below on how the fps of a video works with the refresh rate of a tv.

How LED tv (aka a LCD tv with LED backlights) or LCD tv refresh rates work?
- LED backlights are faster and use less energy consumption than LCD backlights. Both tv's use backlight scanning.

- Many tv's allow viewers to use motion interpolation frames and they are what cause gamer lag and the soap opera effect by creating more fake frames (higher fps) in between the real frames to match the refresh rate of a tv.
- The soap opera effect is when the video looks too life/unrealistic like due the really high frame rates and sceneries may look fake looking.
- Names of motion enhancement technologies: http://en.wikipedia.org/wiki/Motion_interpolation

- Many tv's allow viewers to turn off interpolation and force the television to repeat the same frame a number of times to match the refresh rate of a tv.
- Example: To display 24 frames per second on a tv with a 120hz refresh rate, each frame is repeated 5 times every 24th of a second.

But what happens if the fps of a video does not divide into the refresh rate of a tv equally? = Then you get a a pulldown.
- A pulldown is what causes a jittery screen also known as judder and that's because it repeats the odd frames a different number of times it repeats the even frames of a video. The ratio of the pulldown will depend on the refresh rate of the tv.
- Example: A 3:2 pulldown is most popular because it is needed to match a 24p fps of a video with a 60 hz refresh rate of a tv. = 12 odd frames times 3 is 36 frames and 12 even frames times 2 is 24 frames and 36 frames plus 24 frames = 60 frames for a 60 hz refresh rate of a tv.

What happens if those fps into hz processions cause lag when your playing a video game on a bad tv? (motion interpolation frames is what vendor mainly cause lag).
- Game mode turns off the vendor processors which are what can cause lag when your playing video games, but that means the refresh rate will match the fps of a video which means you then might get motion blur because of the really low refresh rate the tv is running at.

How does a Plasma tv refresh rate work? (plasma also have faster response times to change from one frame to the next btw).
- 600hz = is the total of the refresh rate multiplied by the pixel sub fields = just a marketing term.
- Example: 60hz refresh rate x 10 pixel sub fields = 600hz (or 600hz / 60hz = 10 pixel sub fields). = A plasma tv creates 10 dark images that your brain combines into one full-brightness image 60 times = think of it like interpolation pixels.
= Plasma has no motion blur problems (as long as the fps and sub fields are high) = plasma does not use motion interpolation frames which means no soap opera effect or no gamer lag.

how can i see the refresh rate of my screen?

Jon

okay, recently i realised that verticle sync does nothing but make my games lag. so i turned it off, but i want to know what my screens refresh rate is, other wise im going to have to use it. All though i must admit i havnt seen anything wrong with any of my games yet. Oh another thing, what does it actually do.

Answer
I use a program called RefreshLock to set my monitor hz to 75 when I am gaming, annoyingly enough if I don't use this program when I go into my game my monitor reverts from 75 hz to 60 hz which really hurts my eyes.

Other than this you can usually look at your fps in game with a command, for example in ut2004 it is "stat fps" without the quotes, on my main PC I get 90 fps.
