Dell 18.5 LCD out of range connet to tv tuner Problem video

Please check if all the cables are properly connected. Press the auto button on your monitor to let monitor adjust settings automatically. Then set the resolution to default recommended settings.

Firstly i would suggest you to perform Self-Test Feature Check (STFC)
Your LCD TV when used as a computer display through DVI and/or VGA connection provides a self-test feature that allows you to check whether your LCD TV is functioning properly. If your LCD TV and computer are properly connected but the LCD TV screen remains dark, run the LCD TV self-test by performing the following steps:

1. Turn off both your computer and the LCD TV.
2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital(white connector) and the Analog(blue connector) cables from the back of computer.
3. Turn on the LCD TV.
4. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the LCD TV cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually

This box also appears during normal system operation if the video cable becomes disconnected or damaged.
Turn off your LCD TV and reconnect the video cable; then turn on both your computer and the LCD TV.If your LCD TV screen remains blank after you use the previous procedure, check your video controller and computer system; your LCD TV is functioning properly.

OSD Warning Messages

A warning message may appear on the screen indicating that the LCD TV is out of sync range.
See Specifications for the Horizontal and Vertical frequency ranges addressable by this LCD TV. Recommended mode is 1280x 768 @ 60Hz.

not compatible resolution.

The solution will be that that you need to lower the Video resolution coming out off the Tuner box, it should be in the user manual of this tuner. Right now the video resoltion is too high for the monitor to work, it cannot be higher than the native resolution for the best pictures.

If you have the right Hardware (Digital TV tuner card) it will have come with the software needed.
