Dual Monitor Problem: Primary Monitor Switched?



  • 1. Optiquest Q75
    My monitor has an adjustment button on it that doesn't work. I cannot reduce the size of the pic because I cannot get my mouse onto the MAXIMIZE or MINIMIZE button., I cannot reduce conrast or brightness, I simply want to know if anyone has had such a problem, and what it would probably cost to fix if fixable. Thanks, Mike

    Got a brand new Hanon LCD monitor... Trouble is it flickers from time to time and is really annoying. Any ideas ?
  • 3. LCD monitor dead: diy repair?
    Yesterday it was working fine when I turned it off, but when I booted up the PC this morning my LCD monitor (a 15" Dell E151Fpp) was completely dead - even the little light indicating 'power' was off. Having whipped the back off, I found a blown fuse on the power supply circuit board (which is integrated into the monitor). I replaced this, but when I powered it up there was an instant 'pop' (presumably blowing the fuse again) and the monitor is still dead. Is there anything a non-expert like me can do to repair this? Where would I start? Seems to me that the whole power-supply board is an integral item which would probably unplug for diy replacement (could I get hold of one?), which might be more economical for me than taking the monitor to a repair shop? Any suggestions? Thanks David
  • 4. pc boots into safe mode every 3rd time it is switched on
    hi there, I have a client with an interesting problem. I'm guessing its related to display drivers. hence video. the pc boots normally 2 out of 3 times. the third time it boots to safe mode. I have asked them to check what messages come up prior to bringing it to me to look at. I suspect the display drivers may be playing up. any ideas as to why it would be fine 2 out of 3 tries then every third one goes to safe mode?
  • 5. Help: Getting Graphics Card to Work
    I've just spent three hours trying to get my video card working. I had a system put together minus a graphics card because I wanted to install a Jetway Radeon 9550(95LXAD256C) card that I have. Unfortunately, I'm having problems. With the card plugged into the AGP slot, when I get one beep, followed by three quick beeps when I power up, and there is no signal whatsoever going to the display. Since I get no signal to the monitor at all, my options seem limited. When the system was built, a Diamond Stealth II G460 8MB was used, and then taken out before the system was given to me. The motherboard is an Asus CUV4X and all of the chips on the video card itself are hard-wired.(For what it's worth, I see a bank of 8 dip switches on the motherboard. All positioned upwards, except #4.) I know nothing about IRQ conflicts, and would be nervous about messing with them since the guy who put the system together knew what he was doing, and I don't. Any advice would be greatly appreciated. Thanks a lot. Darren Harris Staten Island, New York.

Dual Monitor Problem: Primary Monitor Switched?

Is there a way to change the default monitor selection when using a
dual display setup under Windows XP?

Currently my external LCD is set as the primary monitor; the option to
change the primary monitor back to my laptop's LCD is greyed out.

My mistake; apparently the 'F5' settings on my IBM Thinkpad T41p are
not reliably maintained by the hardware.

On an (unrelated?) note my laptop actually loses its display settings
after resuming from a screen saver (extended desktop shrinks to one
desktop).  This didn't always happen so I guess I'm publicly confused.

1.swapping primary and secondary dual monitors

I have a Chaintech video card with VGA / DVI connectors on my Dell PC
with Windows XP. I set up dual monitors with one monitor connected to
the VGA connector and the other monitor connected to the DVI
connector. The VGA monitor came up as the primary and the DVI monitor
as the secondary. Is it possible to swap the primary and secondary so
that DVI is on the primary? Thanks.

Simplest way is to just use 2 KVM switches, put the first video output
from each machine, the keyboard, and the mouse on one, and just the
second video output on the other.  Then if you want both monitors on the
same machine pick the same machine on both, if you want one monitor on
one machine and the other on another, then select them that way.

I used to have an option in my display settings for a dual monitor

4.Dual Monitor Problem w/ Games and Videos

Right now I'm really not sure what the problem is, but I'm running a 
monitor DualView setup with nVidia FX 5950. For the most par
everything works ok - I can watch a movie, play game, or anythin
else on either monitor but I can't do one on each.

Anytime I run a full screen app like a game on my primary monitor, th
video on monitor 2 (which is actually a TV) goes out. I can still se
the media player and I still have sound for the video, but the actua
video itself goes black. If I add a tag to the shortcut for the gam
it will run in windowed mode, and then the game and the video bot
run simultaneously just like I want. Unfortunately the mouse is n
longer locked to the game screen... and that makes it so hard t
control the game it's unplayable. So, I was hoping anyone knew a wa
to fix either scenario

a.) A way to keep the game full screen and still have video on my 2n

b.) A program or whatever that could lock the mouse to the game windo
when I run it in windowed mode

Any help would be much appreciated

5.switching to new monitor - what to do on control panel

I have 2 computers at home, a pc and a mac.  The PC has an older AT&T
"low radiation" monitor with about 17" of viewing area.  The other is
a Nokia 447x Pro with about 15.5" viewing area.  The nokia was on the
mac, the AT&T on the PC, both work ok.  Both video cards work.

I wanted to switch them, just because I wanted the bigger one on the
mac even though the nokia is a little sharper.

Putting the AT&T on the mac was straight forward, just had to find a
refresh rate and tweak the shape icons on the montitor itself.

The PC (windows 98) won't come up in non safe mode.  It will hang at
the windows splash screen in perfect color/clarity but will not boot.

Going into safe mode, I'm not sure what I need to do.  Do I need to
find out if my adapter is compatible?  Not sure what I need to do in
control panel, I switched the driver to Nokia 447x pro and it didn't
even require the disk.

Any suggestions, or links appreciated.  This is hard to descibe in a
search engine to get useful information (I do try searching before
