Question about Polyview V17E 17" LCD Flat Panel Monitor

1 Answer

Horizontal Position Unstable

Running monitor at native resolution, and sometimes it would switch on shifted to left, and other times shifted to right 10 pixels or so.
I pressed "auto" to centre it each time it was out.
Came back from holidays and now it is left 20 pixels and will not "auto" correct any more. I can manually adjust it back.
What is the cause of the "amnesia" regarding my settings, and why won't the auto correct work anymore?

Re: Horizontal Position Unstable

Sounds like a electrolytic capacitor has aged/failed in the positioning circuitry. The failure could also be internal to a micro circuit chip. With out skematics and signal tracing I can't say what the problem is. It is possible, however unlikely, someone has spilled a liguid into the adjustment controls and the position switch is shorted causing a constant signal to move the screen.

Good luck

Right click on the back ground of the computer desktop. If windows XP click properties, if vista click personalise. Now look for settings and move the resolution slider to 1024 X 768. This is the native resolution for this monitor.

If you still have the HZ error, click on advance look for the monitor tab, and make sure it is set to 60Hz

I have a 20 inch monitor that the screen is off center.The picture is blank 2 inches on the right and part of the left is missing.

I am guess your have a CRT monitor. There should be a menu button or knob on the monitor. Press it and a menu should come up that will allow you to adjust the position and size of the screen display.

If you have an LCD monitor, the resolution of your desktop is smaller than the screens native resolution. There sould be a button marked "auto" press it and it should correct it. If not, find the desktop screen resolution section in your operating system (control panel) and make sure it is set correctly. If it is wide screen, set it to 16:9 and then set it to whatever has the word "Native resolution" written beside it.

Input not supported error

The native resolution for the x193w monitor is 1440x900. The monitor will only allow certain resolutions. You may need to create a custom resolution using the nvidia control panel.
advanced options display change resolution customize create custom resolution horizontal pixels : 1440 vertical lines 900 refresh I belive is either 75 or 60. Whichever looks better scan type: progressive

Black at left and right of monitor

Since this is a CRT monitor, it doesn't have a native resolution like LCD monitors. You need to adjust the veritcal and horizontal sizes to fit the monitor. On the front of the monitor there are some menu buttons. You need to open the on-screen menu, then navigate to the Horizontal Size and Position menu, use the plus and minus buttons to grow and shrink the image. If it's not centered, use the Horizontal Position menu to move it around. Use this same system for the Vertical menu and you can get your image to fit your screen. By the way, you should have your operating system running with a white (or light colored screen) up when you do this so you can see all the edges of your desktop. The buttons are tricky, but they kinda make sense. Good Luck!

Start up screens are off to the left.

There's nothing wrong with the monitor. Monitors remember the settings for different video modes, including horizontal position. The video mode used when the splash screen displays is a size almost every monitor can handle. Then the mode switches to whatever you've set once Windows finishes startup. As long as the display is normal once Windows is running, you really don't need to be concerned.

If you want to correct the problem, you need to put the monitor into the same resolution and use its menu functions to adjust the size and position. Try pressing F8 when the machine boots to get into the Windows startup menu. This will probably also be shifted, so you can adjust the settings while the menu is being displayed.

Horizontal view on screen will not re-center

You want to locate Position or Horiz Position from the Menu screen. Press menu first then Up or Down to select the item you want then Left or Right, I can't be more specific as all monitors are different - but there isn't a single button to center. You could also try the different input settings (Analog, Digital, etc) if the Autoselect isn't working properly.

Image/screen shifting with mouse position

I realized my issue was that the screen was "slightly" zoomed in using the universal access panel in the system preferences. Turning it off, or zooming out completely solved the problem.

Resolution of the text

What is the resolution that you are running the monitor at? There are two possible reasons that come to my mind.

1. You are running at a non native resolution. Based on your LCD spec you should run it at 1280x1024 resolution to have very sharp text as you normally expect from LCD's. However if you have set another resolution (say 1024x768) the text is blurred and this is a known issue with LCD's, which unlike a normal CRT monitor will get blurred running at any other resolution :(
2. You have not installed the monitor driver, hence again this limits your resolution and windows only allows you to select a resolution that is non-native (Meaning since the driver file is not there the operating system may not allow selecting the native resolution the monitor should run at). You can find the driver file at the samsung site. Its a common driver file for all LCDs.
