Vizio Lcd Tv How Do I Extend My Laptop Display To Our Vizio Lcd Tv Using SVGA Cable?

How do I extend my laptop display to our vizio lcd tv using SVGA cable? - vizio lcd tv

We use an SVGA connector. We brought the first cable to the laptop and the TV when it is turned off and change on the laptop, the Display Properties (step by step) and reported here are the answers. But the TV says is "not compatible", even If the entry is changed to "RGB", and since our computer screen only black. We need to surf the cable from the laptop to move back .. What seems to be the problem?
