set the pc screen resolution to a low setting.
connect the vga output on the pc to an external monitor and check that the video appears on the external monitor. change the mode of operation on the pc until it does appear.
then disconnect the external monitor at the end of the vga cable, and connect the free cable end to the projector and auto source search for the vga input signal

External monitor out of range error on Dell Latitude E-Series portable

If you have trouble getting a display on an external monitor, the issue can be resolved by making the proper settings in the Video Driver Control Panel applet, instead of the Windows Display Properties.

The issue occurs when the display settings for the external monitor are set higher in the NVidia Control Panel than the monitor could display. The settings overrode any Windows Display Properties setting. Similar issues have been seen with the Intel GMA Graphics Controller.

These issue occur docked or undocked with a variety of external displays, projectors and TVs.

So remember that the NVidia and Intel Control Panel settings override the Windows Display Settings.

LP Flatron w1934s, it will not come off of power saving mode when my laptop is attached to my desktop.

Assuming you mean you are plugging an external monitor into your laptop, you need to send the video out from the laptop. You can do this with function (Fn) keys on the keyboard - look for a monitor button and press that with Fn, or you can do it in the dual display settings of your video driver, should be in the system tray (bottom right near clock)

While at home I plug a wide screen monitor into my Dell studio 1737 Laptop. As long as I keep my lid open the icons and print on my monitor are the right size. When I close the lid, icons and prints get...

You appear to be cloning your internal LCD and as long as it is active, the resolution setting for the LCD is also controlling the resolution of the external monitor. When the LCD is closed, then the default resolution of the external monitor is being used by Windows 7 (It apparently has autodetected the size of the monitor and knows the Highest optimal resolution it will display.) The higher the resolution, then smaller the icons.
To resolve, go to display properties and check the resolution of the internal LCD and then set the External display to the lower resolution.
You should be able to wake the system with an external keyboard, by pressing the spacebar, if the system is sleeping

When I use the external monitor S-video port on my Dell Inspiron 1721 running Windows 7 it only displays in black and white despite the internal monitor showing the screen in color.

Okay. For Windows Vista OS.

Go to Control Panel.

Under the Control Panel Home, select Additional Options at the bottom right of the list.

Click on Appearance and Personalization:

At the top right corner of the dialogue box, under Personalization, select "adjust screen resolution"

This will bring you to display settings:

Click the button that says "identify monitors" As each is displayed, it will present a number for which is the default or main monitor (1 or 2) 1 is the main monitor.

To change the external to the main or number one monitor: simply drag the #1 monitor to the left side (if not already there) If it is, you'll want to set the external as the default:

Do this:

While in Display settings, if the external is the #1 monitor, make sure to check the box for "extend the desktop to this monitor" and "this is my main monitor" for the external display. This should switch all settings to the external monitor.

Also, make sure the the resolution is correct for the size monitor you have. For a 20" (such as mine, external Dell monitor) the resolution is at the highest (1920 x 1080).

Also make sure it reads (to the right of that) "highest 32 bit). If this is not an options, make sure you're adjusting the external monitor and not the laptop screen. Otherwise you may need to upgrade your video card.

You should not need to do this though.

After you have set this, go to Advanced Settings and select Monitor. You will see at the top, a list of two monitors; your external with it's brand and name - and the laptop screen type and name. Select the external monitor name: Click on properties, drivers and Update Driver, then select to Automatically search online for driver.

Please let me know if you need further assitance.

I-INC monitor to use with my Dell Laptop, no signal to monitor?

When Windows logo disappear on the I-INC, do you still see it on the Laptop monitor?

All laptops have function keys to switch the screen between the external monitor (I-INC) and laptop monitor. On your laptop, it is Fn+F8 key. Press them once and wait for 3 seconds, it will switch the image between 2 monitors (external monitor ONLY, laptop monitor ONLY, and both).

During start-up, do not close the laptop cover. Because it may put your laptop into a stand-by mode and turn off the screen. You need to modify this Power Option setting within the Control Panel.

I'm frustrated. Love the picture on my Acer 22" monitor with speakers, but the sound is very poor. I have the volume for the computer turned up, but still can barely hear the sound. What can be done to...

Built-in monitor speakers are usually not the best quality. The monitor should have it's own volume control have you tried adjusting it?

You can use external speakers by plugging them into the same jack in the back (green) of the PC instead of the monitor.

Setting the tape speed

Power up camera on Camera mode, go to menu, select camera settings, go to Record Mode and select SP or LP there. Now your camera is ready to record as per selection.
You can not change speed SP/LP during playback mode because its properties of signal set during recording.
