[QUOTE="bobtomay, post: 468414, member: 24160"] 1. sounds pretty strange - don't have a clue why having it connected to the TV would prevent it from shutting down - have had several computers attached to multiple monitors - have not seen nor read anything related to this issue. Maybe can dig up something. 2. What cable are you using to connect it - VGA, DVI, HDMI? What is the native resolution of the LG or what is the model #? (Knowing what country you are in will help us in finding info on your particular model - they do vary in different areas - and it can be hard finding info on a European model from the US and vice versa.) What resolutions does the monitor accept or what is the model #? "Typically" - but verify what resolutions your TV accepts. If connecting via DVI or HDMI - you will want to set the resolution to either 1280 x 720 if a 720p set. If a 1080i/p set, can try 1280 x 720 or 1920 x 1080. If using VGA, you will want to set the resolution to match the native resolution of the display. However, sometimes you need to experiment at the options close to these. The alignment will be a setting through the TV menu, not the computer unless the resolution you're sending to the TV is just not right. (Some of the lower priced HDTV's will not have this adjustment available in it's menu. Some will also make any adjustment you do at this menu item on every input rather than per input, so it usually is better to make sure you have the best resolution prior to adjusting the alignment.)
