Monitor Refresh Rate

[Joel]

What exactly does it do?

I want to be sure, just to be sure.

My monitor was at a 60 hertz and I put it to 75, but it made everything look blurrier. Is this normal? Its an old monitor, manufacture date is july of 94. On the back it says 60 hertz, does this mean that's where I should leave it?

:p

usually..it would/should say

resolution x refresh rate

and if you change your refresh rate...be sure that
'Hide modes that this monitor can not display' is checked...
keeps you from setting the refresh rate to high...
which can damage your monitor, supposedly
dunno if there's any truth to this or not though...



refresh rate

The term you selected is being presented by searchWebServices.com, a TechTarget site for Web Services professionals.

The refresh rate is the amount of times a display's image is repainted or refreshed per second. The refresh rate is expressed in hertz so a refresh rate of 75 means the image is refreshed 75 times in a second. The refresh rate for each display depends on the video card used. You can change the refresh rate in the display properties. However, if you change the refresh rate to a setting that the display or video card cannot support, the display goes blank or the image becomes distorted. It is recommended to consult the display and video card manuals before changing the settings to determine the supported refresh rates.
An older refresh rate standard, developed by the Video Electronics Standards Association (VESA Local Bus), was only 60 Hz. This refresh rate caused the display's image to flicker causing eye fatigue and headaches in users. A new standard set the refresh rate to 75 Hz. It is believed that 70 Hz or higher eliminates the flicker. When purchasing a monitor, look for a refresh rate of 75 to 85 Hz.

Dynamic random access memory (DRAM) memory modules also have a refresh rate. A DRAM module is made up of electrical cells. These cells must be recharged or refreshed thousands of times per second or they lose their data. The refresh cycles depend on the number of rows that must be refreshed. For example, a DRAM module that has 4 rows of cells has a refresh cycle of 4K. Some DRAM modules are able to refresh themselves independently of the processor or external refresh circuits. Since this reduces power consumption, this kind of DRAM is commonly used in notebook computers.

For CRT's....the rule of thumb for healthy use, minimal eye strain, is to have your refresh rate, non interlaced, at 85 Hertz (75 was a pretty old minimal standard) or higher at the resolution you are using. Meaning, if you use 1024 x 768, you ideally should have 85 Hz or higher.

If your monitor looked blurry trying something higher than 60....either the monitors driver wasn't loaded correctly, you were just using some default standard generic PnP monitor driver, or your monitor just can't do it (too old).

I can't find the drivers for this monitor and windows just detects it as a standard monitor. So my video card does't hide anything.

Hm.

Thx again YOSC, mine was set at 75 ... all my icons look clearer at 85.

60Hz gives me headaches after staring at the screen for like 2 mins. :o

I have my monitor set at 85Hz but I wouldn't mind having it higher if possible

[pimptrizkit]

i can get 100hrtz at 800x600 but every thing is soo freakin big..


i live with 1280x1024 at 60 but like a fool i turn it up to 85 with the box unchecked.

im not sure if this helps at all or any thing

I keep mine in the 70s.

you could skip CRTs altogether and get an LCD too; that would get rid of any flicker in an instant. if you do get blurry displays, it can be both the card and the monitor. old screens get out of focus as they age, and video card's DACs can also become fruzzled at high pixel rates (eg high res and high refresh).
