You shouldn't have wasted your money on that card. Just try replacing the cable first.

How to fix my Benq Monitor which is scrolling full screens of different colours.


all modern LCDs have ONE and ONE only native screen size. since you did not tell us the model number we have to tell you maybe you are setting the wrong size. if the monitor has worked before then you are sending it the wrong signal.

I have Benq 19" FP93GX


That sounds like the power section may have problems and is radiating electronics noise ie signals.
If you have warranty get it fixed or replace it. Unfortunately Benq has had quality issues over the years. Sometimes parts and other times assembly. Your's might have both going on at the same time. Monitors are so cheap to buy that they are generally not worth fixing if you have to pay for it. I'm using a benq now and it is one I had to resolder a few places on the board before it worked properly.

When i turn it on it says no signal? Does this


The no signal can either be "no signal" or a signal that is out of range. Check first by connecting the monitor to a known good video output (ie another computer). If that works, then the problem is with the source and not the monitor. Sometimes the source computer has its resolution set too high and the monitor will not be able to process that resolution. The no signal message will occur then as well.

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

Benq 19' LCD Screen 3 yrs old- no signal detected on brand new PC


Have a look at the back of your computer.

See if there is more than 1 video port.

If there are 2 ports try plugging the monitor into the other port....

Sometimes motherboards have internal video cards, in this case the video port is in among the USB ports, sound and mike sockets etc.

Look for a video port away from all those other things.

Benq 19" monitor not working every time when computer started


Check your connections and make sure they are tight, and there are no bent pins. If everything seems ok, you might want to try plugging this monitor into a different computer or plug a different
monitor into yours to determine whether it's the monitor, the video card, or maybe the driver (doubtful on this as you state it seems to be bad somethimes on boot).
