question about screen refresh rate

memory · 03-01-2007, 12:24 AM

Okay I just got my new 19'' LCD monitor which replaced a 16'' inch CRT monitor. I here people talking about refresh rates of like 85 Hertz and above.

Both of my monitors have the same refresh rate, 59, 60 and 75 Hertz. I figured the monitors would have different refresh rates. Do I have to install the software for the LCD monitor before it will change? The refresh rates should be different for the two monitors, correct?

When you are hearing about 85htz refresh rates that is in reference to crt type monitors not lcds there. Phophorous coated cathode ray tubes will depend on a higher refresh rate when running at higher screen resolutions. You will find that the larger model lcd especially will default to 60htz. The more common for lcds is 60, 70, and 75htz.

Lcds will generally run at lower refresh rates even as low as 45htz depending on size and screen resolution set. The software for lcds as a general rule is a driver disk required for some makes and models. The rest depends on the auto detection by Windows and the video card intalled on the system.

Okay thanks. Is higher or lower refresh rate better? One other thing, for the monitor type under settings it just says plug and play monitor. Shouldn't it say like what brand and size? I tried to install the software but there wasn't an option to install any drivers or anything else.

The only place you will find the make and model listed is under display adapters in the device manager. That would be after the needed driver is installed if needed. With the 17" model here XP simply auto detected it and set the screen res to 1280x1024.

For gaming you can try using the advanced button on the display settings to change to the highest supported as seen when looking at either the monitor settings, http://img99.imageshack.us/img99/719...monitorhc8.jpg or the adapter namely video card http://img99.imageshack.us/img99/568...adapterjp8.jpg to bring it up to the 75htz setting to see how well it works. It also depends on how high the screen resolution is set to. You want it where the best quality is seen.

ohhhhhhhh, ok

ya, i don't think that's possible

best i can advise you to do is get a cheap laptop, and set your desktop up as a server

75 Hz on a LCD should be enough. I was running a 21" CRT at 100Hz and now swapped to a 20" LCD running at 75Hz and I can't tell the difference.

Unlike the old style svga crt still in use lcds don't have the "flicker" problem. This is the main reason why the refresh rate is increased especially during gaming sessions to eliminate as much of this as possible. Lcds on the other hand don't have scrolling electrons bombarding a phophorous coating but are strictly controlled by current and the intensity of a backlight.

LCD has a response time, while CRT screens are almost instantaneous, so for gaming I still like my CRT.

Some of those 2ms 19" models look inviting here. Many gamers and those that like lower screen resolutions will stay with crts quite often. The preference here of course is having more desk space available rather then having the feeling of a monitor kind of crammed "in your face" at times. Key board drawers are a little too low for use here as well. Hard core gamers will of couse stick with the old style feel there.

It really depends if its Grey to grey 2 ms or Black to white. CRT's have a higher resolution than most LCDS of the same size. My 19" CRT supports up to 1600x1200 while my 19" LCD supports up to 1280x1024.
