LCD problems

[Scott27403]

Folks,

Just bought a new Kogi 19-inch LCD monitor and I am having problems with it.

First, the image becomes extremely blurry when I scroll through a Web page or document. The image becomes sharp again when I stop scrolling.

Second, I am getting a sort of flickering when I play the computer game Dark Age of Camelot. The problem seems most pronounced where trees and sky meet.

I suspected my refresh rate is set too low, but my Windows control panel won't let let me change it. I am given the options of "adapter default," "optimal" or "60 Hz." But the monitor is supposed to work at up to 75 Hz at my current resolution, 1024x768.

I have an Nvidia GeForce2 MX 400 video card. Tried downloading the latest drivers, no effect. I'm running Win Me, and there don't seem to be any relevant Windows Updates.

Any suggestions? Is this just normal for LCDs? The ones at my office don't seem to have these problems. And even if this were normal, why am I getting no refresh change options?

I'd appreciate suggestions.

Refresh rate sync sounds like the issue. I'd suggest to upgrade to winXP. The drivers are probably newer than the winME versions. Also see if there is a Kogi driver for your specific monitor.

Some ideas:
Slow pixel response time of the LCD panel can cause this problem. The majority of these symptoms are caused by the use of:

>Cable extensions
>Excessively long cables
>Cheap or improperly made video cables
>Improper daisy chaining of monitors
>RF filtering on the video controller card

Interesting to note:
When it comes to gaming or video on a LCD monitor, the key specification is pixel response time. A monitor with a slow pixel response time will suffer from ghosting and streaking in games, animation and video playback. While this was never a problem with CRT monitors, the liquid crystal doesn't move as fast as the CRT's electron beam. Look for a pixel response specification of 16ms.

I had the same problem with a KOGI 15" L4BX which I had a good price on. The solution turned out to be very simple. Go to the monitors control buttons in front and change the frequency value by just a few numbers. As you increase or decrease the frequency you will notice the image instantly get better or worse. I hope it helps.
