Acer x191w monitor problem. Resolution is low and there is a white ghosted vertical band running through the screen. I've checked the resolution and it is set up properly. Also tried unplugging to reset it but no change. I've checked all the connections and everything is fine. Any idea what the problem is and if it can be fixed or is it time for a new monitor?

Acer produces a number of LCD computer monitors. Acer's monitors range from 17 inches to 27 inches. Some monitors offer wide-screen viewing, embedded speakers, high-definition visuals, and various display connection ports. Acer computer monitor problems include common issues such as dead pixels, error messages, and blank screens caused by incorrect connections. Some reviewers have also detected image problems with DVD playback on some models.

"Input Not Supported" Error Message Acer computer monitors such as the G24 may issue an "Input Not Supported" error message when users set the display resolution too high. The G24's maximum display resolution is 1920x1200 with a 60Hz refresh rate. Maximum resolutions vary according to the specific monitor model and according to the capabilities of the computer's video card. b> "Input Out of Range" b> Some Acer computer monitors may report an "Input Out of Range" error message due to incorrectly set monitor refresh rates. Much like the display resolution, each monitor also has specific monitor refresh rates with which it is compatible. Blank Screen or "No Signal" Error b> Like other monitors, Acer computer monitors feature color-coded power indicator lights. If the power indicator light shows green, the contrast or brightness levels may be set too low and should be adjusted via the OnScreen Display. If this does not rid the monitor of a black screen, the monitor may be experiencing hardware failure. The "No Signal" or "Check Cable message" may indicate a problem with the monitor's cable connection with the video card. This error may also appear on a blank screen backdrop if the monitor is plugged into the incorrect port on the computer or if the computer is frozen and needs to be rebooted. Faulty power cords or outlets may cause the screen to be black and to show no power indicator color. b> Image Issues b> Some review sites such as CNET have reported problems with streaking and ghosting during DVD playback on some Acer computer monitors such as the AL1931. (A "ghost" is an identical offset image as the primary or desired image.) Unstable or unclear image issues may be caused by incorrectly programmed VGA timings or incorrectly installed monitor drivers. b> Dead Pixels b> Dead pixels and sub-pixels can cause a variety of display enjoyment problems. Acer will only accept returns on LCD computer monitors that have "more than four (4) defective pixels per million pixels." Further, the central area of the monitor may have no more than one defective pixel. Acer does not differentiate in warranty terms between pixels and sub-pixels. Hope this helps.

It is possible that you've got the resolution and vertical refresh rate set too high. CRTs tend to flicker if the vertical refresh rate is not set to about 72 to 75 Hz. If your screen resolution it set fairly high compared to what the monitor was designed to display it can overtax the video sweep circuitry in the monitor. If possible check the manufacturer's specs.

Often the video driver will let you specify different resolutions for primary and secondary monitor. If you can't find the manufacturer's specs it would be prudent to pick a less demanding resolution or vertical refresh rate for the secondary monitor.

This means you've selected a screen resolution that your monitor is not able to display. Power cycle the computer, and immediately start pressing F8 repeatedly until it brings you to a white text on black menu, select "Enable VGA Mode" and the computer will start up in a very low resolution. You can then go into your display properties and adjust the resolution to a higher resolution that your monitor does support. Review the monitor user's guide to determine the supported screen resolutions.

I've had problems using a widescreen monitor with certain programs/devices when my horizontal resolution is set high enough (for example: 1024), but my vertical resolution is too low (for example: 700). This may be your problem check the display settings and increase if necessary.

Hope this helps you.

Thanks,

Well, if this is the same problem I'm having with my 5810T, then the settings have nothing to do with the vertical lines. There are vertical lines on my acer because the framing of the screen isn't thick enough. Thus, the lines are caused by the lack of sturdiness. Changing settings does nothing. However, pushing on the frame on the bottom of the screen adds more vertical lines. Releasing gets rid of some of them. Tapping also helps, but the problem only gets worse with time.

Most LCD monitors have a default refresh rate of 60 Hz. Older monitors also have limited resolution. Please check your display settings and ensure you're not using a refresh rate higher than 60, or a resolution higher than what it supports. If either one is the case, you're lucky the LCD still works.

on the monitor press the menu button in that adjust the horizontal and vertical size correctly ... you will having the option to adjust in the menu button ...

or you may be using some low resolution check the display properties set your resolution to 1024 x 768 ...


this will fix your problem ...

thank you
bye
any doubts you can reply me
i am always here to assist you
rate my solution

On windows XP and earlier :
1. Right Click the desktop
2. Click properties
3. go to settings
4. the resolution slider is there. Try different resolutions untill it looks good.

Use clear type font

Here is the fix;

1. Go to Screen Resolution
2. Select Acer Monitor
2. Find Advanced Settings and click
3. Find Screen Refresh Rate and change it to 75Hz
4. After the monitor flicks, changes it BACK TO 60Hz.

This fixed the problem for me. Hope it helps. :)
