Trouble with my BenQ monitor

I am running Linux (sp?) on my desktop comp. Once everything loads it works great for about 2 minutes then the screen of my monitor turns white and has pinstripe lines down it north to south and nothing works unless I reboot and the after two minutes the problem happens again .. Is this a setting issue?

You have LCD panel failing issue or it is not getting the proper voltage to the panel. Look at the power supply and logic board section first for failed caps (leaking/bulging tops). check ribbon cable between the logic bd and the LCD panel. If it is vertical stripes, the the T-CON board, part of LCD panel, then you will need new panel.

Trouble with my BenQ monitor


As a general rule, this is a panel failing.
The panel is working for a few minutes until it heats up then begins to breakdown. Blowing air onto it wont help since the area in question is under another panel inside the monitor.
The video control board (inside the monitor that converts signals between your PC and the physical panel) could be failing.
Another source of the problem, though rare, is the capacitors that filter power for the panel's power supply (on the main powerboard) begin to break down and that is enough to cause the issue.

Because this is a BenQ, it may come back to life if you replace any capacitor that looks even remotely suspect & resolder all the main components on the powerboard.
Be warned, there are dangerous voltages stored by the main filter capacitor that can kill even if the monitor has been unplugged for several hours.

Just got a hand me down Benq model t903 19


Quite the opposite -- your new monitor can't handle the screen settings that you're running on the old monitor.

Hook up the old monitor and start up the computer so you're looking at a Windows desktop. If you have windows open, close them or minimize them down to the taskbar so you can see the desktop/background image.

Right-click on the background image and select "Properties" to bring up the Display Properties dialog.

There are tabs across the top of this dialog -- select the one named "Settings"

In the bottom half of the Settings tab, there's a control named "Screen Resolution" with a slider to move between "less" and "more"

Move this slider to 1280x1024 or lower. If you're already at a resolution smaller than 1280x1024, then set it to 800x600 and we'll troubleshoot from there.

Hit "OK" to accept the new settings. Windows will ask if the new settings are OK -- click on "yes"

Now unplug your old monitor and plug in the Benq.

If you are happy with this screen resolution, then you're done!

If you're looking at 800x600 and want to see more, then repeat this process -- go to the Display Properties -> Settings dialog and try a bigger resolution. Hit "Apply" instead of "OK" to try a new setting.

If the screen says "OUT OF RANGE" for a setting, just wait for 15 seconds, and windows will revert to the old (working) settings.


Let me know how this works! If it's helpful, click the little thumbs-up. If it's not, ask questions and I'll try to explain in more detail

It sounds like the video card could not handle the monitor in the board room - As it is unless you have a graphics based laptop you rarely get a high quality video card built into your laptop.

Causes aside boot your computer in safe mode - This is done by tapping F8 several times during startup

A menu should pop up - select boot in safe mode

A long list of text will pass in front of the monitor - Do not fret this is just Windows telling you what it is loading.

Once at your desktop you should be able to see everything clearly

Right click on your desktop

Goto Properties

Settings

Drag the Screen Resolution down to something more appropriate e.g. 1024 x 768

Flatscreen goes blank and displays the message


Out of range indicates that the refresh rate or resolution is set too high for the monitor to display. I would suggest re booting into safe mode by pressing F8 during boot, before windows begins to load. Select safe mode with networking if you can, and once in safe mode, uninstall the ati display driver from the control panel. Then go to ATI's site and download the latest driver for your card. Save that file to your desktop. Reboot normally, as Windows should load default vga drivers for your card. Once in Windows, install the latest driver you just downloaded. That should reset the resoultion to one that your monitor can display. Good luck:)

Philips game trouble


When your game first loads. Enter the games settings and adjust the screen resoultion to match your wide screen monitor. If you can't get that far than hook up that other monitor. Load the game & enter it's screen settings (display) & adjust the resoultion. Your new monitor is wide screen. Your game needs to match the wide screen as well.

Good Luck!

Benq monitor powers off immediately


Try sending monitor back as most Benq monitors come with at least a two years silver warranty. Benq are very helpful and their repairers are quick and polite. You will find their no.s on their website www.benq.com my monitor was experiencing the same and for $10 postage and a one week wait is repaired and working fine.
