Tap the info button on the TV remote to see what resolution and frequency is being sent to the video board then the signal is upscaled to 120 Hz the numerical value displayed when info is tapped is the input signal value before processing to the panel resolution and frequency
Connect the VGA cable to the converter and the component video cable to the TV and the converter with the computer and TV off. Turn on the TV first and set it to the component video input and then turn on the computer. Then (assuming the VGA port is enabled - adjust in the BIOS if needed) set the computer's video output to the VGA port. (On my Windows 7 laptop, this can be done by right-clicking on the desktop. Choose Graphics Properties and set the display to the external monitor or both. Click Apply and then confirm the change (on the external monitor if using the single monitor). (VGA to Composite video converters also exist if you do not have an available component video input on your TV.)
If your computer is fairly new, you may have an HDMI port. Your TV may be able to read the signal with a DVI to HDMI cable. (It depends on the TV. Not all of them will read the computer's signal on the DVI port. Check the documentation for your model. TVs without a VGA port are less likely to support this feature.)
In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together.
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available.
2. Connect the other end of the cable to the side of the RGB adapter with the single input.
3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter.
4. Connect the other end of the RGB cables to an available component input on the back of the TV.
5. Tune the TV to the component video input you used through your television's menu.
6. Turn on your laptop. The laptop should now display on your TV screen.
You need to set your MAC video resolution to the native resolution of this TV in PC mode, please read your manual to find out what that is, if the resolution is set too high, the TV will not be able to display it.<br />

the dvi out of pc via adaptor to hdmi on tv has no audio,ok.
so LG diagram shows separate audio into Audio in RGB/DVI.
Resulting in video in on HDMI ok,but audio on RGB.Can not get both together.
Fix is revert to DVI to RGB lead with audio on RGB/DVI input.
The audio jack would only work with mono plug for audio in, to RGB.
Your laptop will have a VGA output or possibly a S-video out. For the
VGA you'll need a standard VGA cable. Plug the cable in to your laptop
and the PC input of your TV. If your TV does not have PC input it may
have a DVI input. IF it does you can use a VGA/DVI adapter to plug it
in. If it doesn't have a DVI input you can use the S-Video output on
your laptop with a standard S-video cable. After the connection to your
TV is made you will have to toggle alternate display by pressing and
holding your [Fn] key and pressing F4, or F5, or another F# key. It's
the one that looks like a TV screen. Press once to turn on output,
press again to turn off your laptop screen, press again to go back to
laptop screen only
To my knowledge, the Sharp LC-42D62U do not have a VGA or DVI inputs. While they lack dedicated PC inputs, you can make use of one of the HDMI
inputs, use a DVI-to-HDMI
adapter and connect to a computer that has a DVI output.
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.
