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

Daniel E: How do I extend my laptop display to our vizio lcd tv using SVGA cable?
We are using an SVGA cable male to male. We connected the cables first to the laptop and tv when it’s powered off and then when we turned on the laptop, changed the display properties(step by step) as mentioned here in Y answers. But still our tv just says “Not Supported” even if we changed the input to ‘RGB’ already and then our laptop screen just goes black. We need to unplug the cable from the laptop again in order to navigate.. What seems to the problem?

Well , you could be using the WRONG Refresh rate or resolution setting on your computer….

Set it to 60 Hz refresh rate and KEEP that setting…then start at any hhhh x 480 resolution setting and move up to hhhh x 720 settings and finally stop at 1920 x 1080. You will note that several settings will not provide a picture.Those are the ones that the TV will not process….

Now, if you still get NO PICTURE at all then replace the signal board, or the cable…
