I accidentally disabled my laptop monitor while trying to use another one. How do i turn it back on? dell latitude 610


You should be able to disconnect the external monitor, and then restart the computer to recover your defualt monitor.

If not see if oyu can move your mouse around enough to see the mouse on the second monitor, from there it depends on which operating system you have. That particular dell has XP...

So you would right click, go to properties, Settings tab, then click on the monitor you want to activate. Look for the check boxes, and click extend my windows desktop onto this monitor, then check the use this device as the primary monitor.

My main vga monitor has no signal until windows starts loading, but my secondary connection (hdtv) has signal as soon as i power on my pc. If i need to change my bios settings then i need to have my tv on...


It looks like you have your TV set as your primary display, you will need to open up control panel to change this. I'm assuming you're using Windows 7 (the process should be similar for Vista and XP).
Open control panel > Appearance and Personalisation > Display, and choose the "Change display settings".
There should be a button that says "Detect" or "Detect Displays". Click this button. You should see something like this:

Click the icon which corresponds to the monitor that you want to make you primary display (the boxes numbered 1 and 2 represent your two displays). Since you have yours the wrong way round, you should click box 2. If any check boxes come up saying "do you want to make this monitor your primary display, say yes. You should then have your monitors the right way round.

So I hooked this moniter up to my hp and all I get is two blinking lights


One monitor serves as the primary monitor, and this monitor displays the Logon dialog box when you start your computer. In addition, most programs will display windows on the primary monitor when you initially open them. You can select different screen resolutions and different color quality settings for each monitor. Multiple monitors can be connected to individual video adapters or to a single video adapter that supports multiple outputs. To configure the arrangement of multiple monitors:
  1. Click Start, and then click Control Panel.
  2. Click Appearance and Themes, and then click Display.
  3. On the Settings tab, click Identify to display a large number on each of your monitors. This shows which monitor corresponds with each icon.
  4. Click the monitor icons and drag them to positions that represent how you want to move items from one monitor to another, and then click OK or Apply to view changes.
NOTE: The icon positions determine how you move items from one monitor to another. For example, if you are using two monitors and you want to move items from one monitor to the other by dragging left and right, place the icons side by side. To move items between monitors by dragging up and down, place the icons one above the other. The icon positions do not have to correspond to the physical positions of the monitors. You can place the icons one above the other even though your monitors are side by side.
Change Primary Monitor
  1. On the Settings tab of the Display Properties dialog box, click the monitor icon that represents the monitor you want to designate as the primary monitor.
  2. Click to select the Use this device as the primary monitor check box. Note that this check box is unavailable when you select the monitor icon that is currently set as your primary monitor.
View Same Desktop in Multiple Monitors
  1. On the Settings tab of the Display Properties dialog box, click the monitor icon that represents the monitor you want to use in addition to your primary monitor.
  2. Click to select the Extend my Windows desktop onto this monitor check box. After you enable this feature, you can drag items across your screen onto alternate monitors. Or, you can resize a window to stretch it across more than one monitor.
Move Items Between Monitors
  1. On the Settings tab of the Display Properties dialog box, click Identify to display a large number on each of your monitors. This shows which monitor corresponds with each icon.
  2. Click the monitor icons and drag them to positions that represent how you want to move items from one monitor to another, and then click OK or Apply.
  3. Drag an item on your desktop across your screen until it appears on the alternate monitor. Or, you can resize a window to stretch it across more than one monitor.
Using DualviewOn many portable computers and some desktop computers (those with two video ports on one video card), you can expand your display to a second monitor by using Dualview. Dualview is very similar to the multiple monitor feature, with the exception that you cannot select the primary display. On a portable computer, the primary monitor is always the LCD display screen. On a desktop computer, it is the monitor that is attached to the first video out port. Once you attach the second monitor and turn on your computer, use the Display tool in Control Panel to configure your settings, just as you do with multiple monitors. You can use Dualview with docked or undocked portable computers.

Dual monitor setup


Assuming you are using Windows Vista:

All you have to do is connect your laptop to a monitor via a VGA port (located on either the side or at the back of your laptop - it's the port with about 15 holes).

Once connected , you will need to configure how your 2nd monitor will function - as an extended or duplicate monitor. To set this you will need to go to Display Settings > and select your option.

Outputing to an external monitor


Hi Coupon,

Connect your external monitor to your PC. Reboot. If the monitor don't show your desktop. you may have to turn the option on. In the lower row of keys, is one called Fn. It is a specific color. Hold that and look at the top row of key. You should see marking, the color of the FN key. one will show your lappy screen, and a monitor. Tap that one. Usually, each tap moves to a different option. First tap is Laptop screen only, next one is monitor only, another is monitor and laptop screen.
Then right click on your desktop, in a clear area.
Go to properites>Settings and your should see both your screens. Here you can make one your primary, by click on the screen you want as your primary, (I suggest the lappy) and click the box, Make this the primary. Then click on the box names Extend my Desktop. This allows you to move your mouse and Windows, to either screen.
If your lappy doesn't have a Vga out port, a blue one, on the back, you will have to get a USB video card, but they are rather expensive!

Good Luck!

Using my tv as a monitor


Right click on desktop, then go to properties. Click on the settings tab. There should be two boxes, labeled 1 and 2. Click on box 2 and select:
Use the device as the primary monitor and Extend my Windows desktop onto this monitor. Also go to advanced -> Monitor and make sure that the screen refresh rate will not damage your tv. For older tv's it's usually 60 Hz for NTSC and 50 Hz for PAL.
After getting your settings where you want them, click apply. This will transfer all video output to the auxillary screen and will leave your primary monitor blank until you change the settings back to the primary screen.
