Question about Proview PL913S 19" Flat Panel LCD Monitor

1 Answer

Extension cable I added an extension cable to my monitor and am now having a couple problems.  The  first one is the screen seems fuzzy.  I tried making adjustments with no luck.  The second problem is that the screen size shrinks to about 3/4 size when it sits for any length of time.  I can reset it to full size but it happens again when it sits Could this all be caused by an inferior cable?

By all means yes. Longer VGA cables need superior shielding, and signal degrades over distance. So either get a better extension cable or move your CPU closer to the monitor and run extensions for your keyboard and mouse.

I connected an external monitor to a lap top. The screen on the monitor is bouncing making all the print fuzzy and difficult to read.

Have you tried the same connection with another monitor? That will tell you if the cable or monitor is the problem. If the same thing happens with another monitor then its the computer input or system drivers.

My t.v screen is fuzzy and the picture is showing double on one side and it at times seem s streched

The stretching might be due to having the wrong aspect size on your tv. Look on your remote and see if you have a button that says "Aspect" or it could say "ratio" or something to that effect. You can cycle through the different screen sizes to make it not appear to be stretched. As far as your picture being fuzzy, if you are using a standard antenna that may be the cause. If you are using cable, I would contact the cable company and have someone come out and check your signal strength, and possible inquire if you need a cable booster added. If you are running cable through a cable box and are running it straight coaxle then I would recommend trying a different hookup method, e.g Red, white yellow cables, or S-video or even hdmi, whichever your cable/satellite box and tv allows.

I have a Westinghouse LCM-22W2 LCD monitor. I believe my power board is bad. I want to either replace the power board or bad capcitors, if I can find them. I do not know how to take off the back cover,...

Have you gone through the user's guide? There are some sleep settings and automatic adjustments that this monitor makes, and other changes that users have inadvertently triggered that seem to be causing quite a bit of confusion these days. Make sure you haven't overlooked the Troubleshooting steps outlined there:
No Power
• Make sure the AC cord is plugged into the back of the LCD monitor.
• Make sure the AC power cord is securely connected to an AC outlet.
• Plug another electrical device (like a radio) to the power outlet to verify that the
outlet is supplying the proper voltage.
No Screen Image
• Make sure monitor is turned on.
• Make sure the video cable is securely connected to both the monitor and PC or
Audio/Video apparatus.
• Make sure you have selected the correct video input source
• Adjust the brightness and contrast levels.
“Out Of Range”
• Restart your computer and adjust your desktop resolution and refresh rate to 1680 x
1050 at 60 Hz.
Fuzzy Image
• Set desktop resolution on your PC to 1680 x 1050 at 60 Hz.
• Adjust Phase/Sharpness setting on the monitor
Cannot find 1680 x 1050 under screen resolution on my Display Properties
• You may need to download and install the latest video card driver for your PC.
Listed below are websites for major video card manufacturers:
Image Too Bright or Too Dark
• Adjust the brightness and contrast levels under the OSD menu.
• Make sure the video cable is securely connected to both the monitor and PC or
Audio/Video apparatus.
• Perform Auto Adjust.
Distorted Image
• Reset the LCD monitor by performing the “Reset” function using the OSD.
• Remove extra accessories (such as a VGA extension cord).
Image is Not Centered (size is not scaled correctly)
• Perform Auto Adjust
• Adjust the horizontal and/or vertical position using the OSD.
• Check image size setting.

Benq screen resolution auto adjust seems to auto adjust wrongly

I would recommend you to bring it back and get a new one, if its till under warranty. You cannot fix the problem on the panel buttons it looks something to do with the components in the circuit bord.

Fuzzy screen, not a flat screen.

TFT Monitor fuzzy display problems are almost always caused by one (or more) or the following issues:
  • Wrong display resolution. As mentioned elsewhere, TFT Monitors must be configured to use their Native Resolution in the PCs display settings. Failing to do this will always cause the display to be fuzzy or blurred - or to have jagged edges on diagonal lines and a 'lumpy' looking display.
  • Poor adjustment. If the display resolution is correct, then the monitor has to be correctly adjusted to get the best picture quality. This is usually only an issue with analogue monitors. If the digital (DVI) input is used, then further adjustment of the monitor should not be required. Initially, the monitors "Auto-Adjustment" can be used to try and improve the display quality. This is best used with a program producing a test pattern of vertical lines, with a single pixel white border showing the exact edge of the screen. Given this, most monitors will auto-adjust perfectly well. If the display is still not perfect, a very slight manual adjustment will usually achieve the expected quality.
  • Poor quality cables. Monitors are susceptible to signal degradation from either poor quality or excessively long signal cables. Also, joining or extending cables is likely to cause ghosting effects on the display, usually seen as light and dark vertical lines.
  • Faulty graphics cards or other component. In most cases upgrading the driver ill resolve this issue. If none of the above suggestions work then get me the brand and model number of your graphicscard and we will update the driver.

I have posted this response to similar problems.

Your display being fuzzy as you described is indicative of either:
a. weak picture tube; or
b. component failure or deterioration.

Even if it were a weak picture tube or deterioration, it is still possible to "squeeze" a few more usable time out of the monitor. You simply have to adjust the focus control. Normally, this is accessible from the rear of the electronic circuit board and is a part of the Flyback transformer (FBT). Below is an image of a sample FBT. Pls notice the two (2) protrusions, one of them is marked as Screen and the other as the Focus. You need to adjust the focus till it satisfies your visual requirement or preference.


A word of caution. This procedure is not recommended if you have no TV/Monitor repair experience. It is not a fix. It is as earlier stated, squeezing in just a few more usable time. The unit would have to be adjusted "live" with the cover off. You need to be familiar with electronic components, tools and circuitry as well as working with powered devices and extremely High Voltage. The monitor may have to be operated with insulated support since the back cover will not be attached. Additionally, you may need to use a mirror to check if you adjusted it as you want it.

As you try to adjust it with an insulated screwdriver, you will notice that there is mid point where the focus will just be about right. You may have to adjust a couple of times to get the setting as you want it.

Should you feel uncomfortable doing this, perhaps you may need to seek the assistance of a qualified TV/Monitor technician.

Hope this be of some idea/help. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
