Dual monitor problem

I am trying to use an additional monitor to show a different screen to that of my laptop so that I can use PowerShow for PowerPoint - Laptop to show slide sorter and other monitor to show Slideshow. But whatever I try it does not seem to recognise the PnP monitor as an additional screen but just as a duplicate of what is on my laptop
What do I have to do to configure my laptop properly?

Yea i have a gateway 450sx4 laptop and when i turn it on it stays black for a while and when the screen finally turns on it blurry and its different colors and it just shows lines how can i fix this?

It's likely that your screen is "fried" (faulty) ... try to connect your laptop to an external VGA monitor, and see if the screen shows up (on the external monitor) properly. You may have to toggle the output display (device) from computer screen to external monitor ..using Fn+F3.
If it displays on your external monitor properly, it means your laptop screen is no good. You can replace the laptop screen, or just continue to use the external monitor.
If it does the same (blurry & different color, etc.) on your external monitor, then, your video card/module on your laptop is bad. This usually happens less often.

I have a problem with displaying power point presentation

Hello, Chris.

I'm not certain if this was already tried, but here goes:

If you look at you keyboard function (F) keys, you'll see a symbol or the words "CRT/LCD". On my laptop, it is F8, but could be different on yours.

When you connect an external screen to your laptop, if the laptop information doesn't show on the external screen, press your Fn key plus that function key with the symbol or words.

Normally, when you press once, twice and three times, you toggle through various options: your laptop screen only, your external screen only and both screens.

Hope this helps.

Monitor will not display

Your display app controls that, try updating drivers/ software for graphics card on laptop.
Or press the monitor button (usually Fn + something) till it comes right

Laptop dispalys to monitor but laptop panel cannot be activate


Thanks for all the details..

The issue seems to be with the video card drivers here...

Go to and download the latest video card and the chipset drivers

before you download ...uninstall the nvidia chipset or any display software from program and features.

after you have installed the software.. go to the nvidia control panel > setup multiple monitors. and browse throughout the options >
It should be dual display and not extended display.

Also try with a new user profile...

Hope this helps..

Blank (dark) notebook screen after hooking up digital ext monitor

I notice a difference in the setup of the two monitors, have you installed the correct driver for the new screen?

Try F8 on startup to get into safe mode, this should allow you to use the default VGA screen, and to reset the correct monitor drivers.

Data Shows up only on External Monitor, not on Laptop Screen

If your system won't display anything w/o the external monitor. there's something wrong with the LCD's backlight. you may have to contact your laptop's manufacturer and check if this laptop is still under warranty. you may have to get the lcd replaced.

Double display with my IBM think pad T43

have you tried Function F7/F8 ?
Make sure that your display driver is installed correctly.
I had the same Laptop as you did and was able to have dual monitor.
Also check your Display driver in your control panel and make sure it set to dual monitor.

Data Shows up only on External Monitor, not on Laptop Screen


Since the laptop works on the external monitor, then it would be safe to assume that it is only the L:CD display part that is the issue. Often LCD display (of laptops) are working but only that you can see the actual display. One way to verify is to shine a flashlight at an oblique angle to the screen, semblance or part of the desktop could be seen. If the desktop could be seen (albeit very very dark background) then it could either be the CCF Lamps (cold cathode florescent) or the inverter that powers the lamps.

Often, the defective component would be the inverter. It is relatively easy to replace the inverted. It is sometimes more difficult and challenging cracking open the casing of the display panel of the laptop than replacing the inverter. Additionally, inverters are readily available online. It is also not surprising that inverters for other brands/models would also be used in your Toshiba.

This would be a good place to start for inverter boards. This is a nice tutorial if you are considering a DIY.

In some worst case scenario, it could be the video interface or even a loose/open flat cable from the laptop's main body towards the LCD display panel.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
