Re: cannot st maximum refresh rat

Usually you can only change the device options if windows XP recognizes the device. Does it show up as a viewsonic E50cb in Device manager (My computer, Properties, Device Manager) or just as Plug and Play monitor? I would download the drivers (or if you have the CD) for the specific monitor you have and then I bet the options will open up for you the way they should be.

Tell me what is samsung syncmaster 794 default setting

The maximum resolution supported is 1280 x 1024 pixels at 65 Hz refresh rate, while the recommended resolution stands at 1024 x 768 pixels at 85 Hz. However, the maximum usable resolution is 1152 x 864 pixels at 75 Hz. Maximum usable resolution signifies the maximum resolution supported by a monitor at a refresh rate of 75 Hz or better. Though 85 Hz is an ideal refresh rate, 75 Hz is the lower limit. Any refresh rate, lower than 75 Hz, will give a flickered output and can cause some serious eye damage after prolonged usage...i hope this helps.

What should the display rate be set at for a Viewsonic VG910s. The default is 60 MHz - can it be changed to 72 MHz?

The default is 60Hz (60 cycle, not 60MHz (60 million cycle) for Vertical refreshing rate.
From user manual:

"For the best picture quality set your LCD display timing mode to:
VESA 1280 x 1024 @ 60Hz. "
and here is the warning:

"WARNING: Do not set the graphics card in your computer to exceed the maximum refresh rate of 75Hz; doing so may result in permanent damage to your LCD display."

I havE A VEIWSONIC Va520 when I turn it on , it brings up a screen saying out of range H-30-62 KHZ V-50-75 Hz what does this mean?

1. maybe the problem is with windows, because the refresh rate is set to an acceptable value

2. your lcd screen runs at higher hz than 60

3. you are running a resolution higher than 1024x768 15" LCD's generally can only support 1024x768 whereas larger panels support higher resolutions.

Possible solutions

1. The LCD you buy is shipped with a plastic cover over the screen which shows maximum resolution and recommended refresh rate. When you first turn on your computer press F8 to access safe mode, after you enter safe mode, configured the required setting on your lcd monitor. when you are done, reboot or restart your computer, hopefully your computer should be fine.

2. attempt to access the bios setup utility by pressing del or f2 of your keyboard after you see the initial display of your pc, if you can see it, the problem is with windows because the refresh rate is set to an acceptable value. Set it to its required settings by entering safe mode as posted on no.1

Go for the highest your video card will allow to remove any flicker from the screen, or the max whichever works best.

How do I install it? It was donated. No instructions.

Plug it in to your PC/laptop. Windows should recognise it and assign it basic drivers. Go into Control Panel, Display to change the resolution and refresh rate to what you want. No real need for manufacturer specific drivers but you can probably download them from viewsonic if you want.

Digital Repop

Hi, Even if it is refreshing, shouldn't be that noticeable. One possible reason is not enough memory in your video card for which you can try compensate by increasing the Graphics Aperture Size in your CMOS/BIOS setup. Normally it should be twice of your on-board/add-on video card memory. Another possibility is your LCD monitor is showing signs of pending problem which could either be the CCFLamp, the inverter that powers it or the video interface. Some models of Viewsonic are known to have inverter failures. Specifically, the capacitors are overheating and would need replacement. In some instances, it is the lamp that goes or still others are simply cold solder joints. Hope this be of some help/idea. Post back how things are or should you need additional information. Good luck and kind regards.
