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:
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.
