I am trying to hook my 40 inch flat screen by samsung to my dell computer. i unplugged the cpu monitor and plugged it to my tv and the tv states that the mode is unsupported. What do i do?

Hi,

I am assuming that you are connecting the Dell PC to the Samsung 40 inch flat screen by VGA connector/cable.

Perhaps what might be causing no display in the Samsung FlatScreen is that the video signal it is receiving is beyond its capability. To correct this, pls:
1. lower screen resolution of your laptop's properties.
2. it may also be of help if you likewise lower the screen refresh rate.
Both of the above may be adjusted through the appropriate settings in your Display Properties of the Dell PC before you remove the monitor.

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.

Your computer is set to a resolution supported by your dell monitor but not the flat screen tv.

The easiest way to get it working is to turn the computer off, connect the flat panel to the computer and then turn the computer on.

To change the resolution of the flat-panel or monitor, right-click on the desktop, click on properties and then select the settings tab.

play with the screen resolution and find one that works best by trying each one and clicking apply. If you select a resolution not supported by your flat panel, computer will automatically revert to the previous resolution in 15 secs.
