I. Preface

LCD flat-panel TVs are now quite popular, but for TVs alone, the 16-9 wide screen is obviously not suitable.

Summary:
When Samsung and many other brand LCD TVs are connected to a computer through VGA, The vgaine must have 15-pin full access (available in
Purchased from the market or tested by A multimeter). Otherwise, no connected device may be displayed. This cannot be ignored. In addition, the vgaine Quality
The quantity must also be guaranteed. If the TV screen is reddish and green after VGA connection, most of the cases may be caused by a vgaine needle.
When a computer is connected to an LCD TV, multiple display devices are displayed on the display device.
Or switch by displaying the switch key (the Dell d610 is FN + F8 ). LCD TVs and computer displays
The resolution is inconsistent. Generally, you need to switch to "LCD TV with signal computer display without signal ".

There are some regrets about the VGA connection mode, that is, the audio noise. I have tried the VGA connection between Hp ipv2tx and Dell d610,
Neither XP nor Vista can completely eliminate noises. (Note: Samsung la32a550p1r needs to be in audio control.
Turn off the "Automatic sound companion" option to reduce the noise .) However, in either case, the battery is used only if the external power supply is not used,
In addition, the audio is converted through Bluetooth, that is, the public-to-public audio line is directly connected to the TV and Bluetooth headset, and the computer uses Bluetooth

I think there may be a better solution to the noise problem, and further research is needed.
