Question about IBM ThinkPad T20 2647 Notebook
I have my PC connected to a Vizio LCD using a standard VGA to RGB connection. The sound is awful and sounds echoed using a standard audio speaker cable from the tv to the speaker (green color coded) jack on the back of the PC.
There is also a HDMI connection on the video card, will this work and will it transfer sound for the tv and the computer.
Keep in mind the LCD is only an extension of the PC monitor and is not used for TV purposes.
Any help would be nice...
You have an HDMI connection on a Thinkpad T20???
Per definition, HDMI is supposed to send video and audio data from the TV to the PC -so, yes, it should work.
I say "should", because I tried to hook up my PC that way and I went back to a VGA connection (and sent the sound to an old stereo), because the resolution was awful.
I rather think that the audio cable is the culprit here - if the connectors are not fitting perfectly, they can create a lot of distortion.
Also check your audio settings on the PC (updated driver, settings not on maximum volume, etc.)
If you want to try HDMI, there is no need to get the ultra expensive "Monster" cable. Look here for an example.
