Question about BenQ Professional P211 (White) 21" CRT Monitor

1 Answer

Loss of Display

The monitor is perhaps 2 years old, and is used only at home. While working on the computer, the screen width began to shrink. Adjusting the horizontal width setting increased the width, but the shrinking continued, until finally the display totally disappeared. Recycling the monitor power had no effect. Hooked up another monitor to the computer, and verified that the video card was still functional. Monitor had been on perhaps 12 hrs, but this is not unusual for a weekend.

My acer monitor p244w has a clock setting on the menu.--what is this clock setting for?

The "clock" refers to the internal oscillator clock circuitry that is responsible for the generation of the video signals. It is NOT used to set the time on the monitor. It is used to make adjustments to how the display looks, usually stretching/shrinking the horizontal width.

Can't see the part of the page with buttons to -

The monitor will have a few buttons on it, in addition to the ON/OFF button.
Press one of the other buttons to activate the OSD (On Screen Display).
From the OSD, you can "shrink" the horizontal width of the "visible" part of the screen, to pull the '_' and the 'X' controls onto the screen.

Monitor sizes are measured on the diagonal from corner to corner.

A 17" LCD may have a screen width of 12 inches measured from side to side.

If you are measuring a old style CRT monitor (Cathode Ray tube) the visible screen area will be about an inch less as there is about 1/2 inch of plastic frame holding the CRT in the chassis. The manufacturer can advertise the actual size of the screen regardless of how much is actually visible to display information.

If you are talking about software not utilizing all the available screen area to display the image, that is an issue with the people writing the software code not keeping up with the changes in hardware.

In the past year or two, most displays have switched to the 16:9 and 16:10 wide aspect ratios while most web content is still written for the 4:3 old style aspect ratio. Eventually, software developers will catch up with cusrrent hardware.

Acer 19167W flat screen

Depending on the application you are viewing the picture in you can shrink the application window. You could reduce the size of the viewable area but that defeats the purpose of the wide screen which is to provide a better viewing experience (to quote the marketing types). It sounds like....since the wider screen really has nothing to do with your picture might want to adjust your picture size independent of screens and applications. There are a variety of free products out there that can do this...and some are really nifty...perhaps better than the software you might now be using.
