Most of the times it is the driver or the video card itself. Some of the older video cards do not play well with HDTVs. Remember you are connecting to a HDTV and not a computer monitor and most HDTVs only have limited PC support. Consult your HDTV manual for the resolutions and refresh rates the PC connection will support and set your resolution to match. If no joy there you might consider getting a new video card that will support the native resolution of your HDTV.

Maybe, but more likely not. Hard to imagine that a switch or splitter could solve any sync problems. Maybe that was some clever method to promote something?

The resolution you use needs to be one that your LCD TV accepts. What size is the LCD and model, what resolutions does it accept and what type of video card do you have? Do you have 2 outputs (monitor & TV) or just the TV?

I purchased my TV and computer at the same time about 4 or 5 years ago and my HP computer is a media center and specifically for hooking up to a TV. I change the computer resolution to match the resolution listed in my TV manual, when I connect the computer to my TV and reboot my computer the windows start up image appears on my TV at first but then it flickers a couple times and the shows "no input". When I reconnect my computer to my monitor and look at the screen resolution, the computer has reset to the higher resolution that is not supported by my TV so that is why my TV is kicking the signal off...how do I keep my computer from resetting to that highter resolution? is it auto detecting my TV and trying to adjust the settings accordingly? because if I change the resolution and then restart my computer when it is still connected to my computer it maintains the settings....this is sooo frustrating...

What's frustrating is asking you for information that we can use to help and not getting it. Computer model, video card, TV model. Are you outputting to a monitor and the TV or just the TV.

We can't help you without having some basic information to work with.

RBINCK....you hit the nail on the head...after installing Windows 7 it was using a Windows display driver and all I had to do was install the driver for my NVIDIA card and all is well......Thank You!!!
