Look for a button on the remote or the TV itself labeled Source or Input. This should let you change the input between TV, AV, HDMI (on some TVs), and PC. Just press the button repeatedly or use the up/down arrows.
Before setting the input to PC (VGA), turn off the TV and the computer. Then connect the VGA cable (M-M) and the audio cable (a 3.5 mm M/M cable, if you plan to use the TV speakers) between the two units. Next turn on the TV and set the input to VGA. Then turn on the computer. (This is if you are using the VGA or D Sub 15 connection.) For a desktop, if you do not have another monitor connected, the TV should automatically be detected and the resolution set with any Windows OS (XP and later). However, you may need to reset the resolution and the refresh rate. For Windows 7, right click on the display and choose Screen Resolution.
For a laptop, you may need to enable the video port in the BIOS. Accessing this depends on the manufacturer of the computer motherboard. (Often Esc, F1 or F2 is the key to press after turning on the computer but before the OS loads. This can be tricky to time correctly.)
With a laptop or a desktop with another monitor attached, you will need to tell the computer how to deal with the multiple monitors. (Extend, monitor 1 only (or laptop internal monitor), monitor 2 only (external monitor), or dual display.) For my HP laptop with Win7, I choose Graphics Properties instead of Screen Resolution. There may be a keyboard Fn shortcut to access this.
Some TVs will accept a PC signal on the HDMI port (directly from an HDMI port on the computer or via a DVI to HDMI cable). Not all TVs do this. (Without the model for your TV, I can't confirm if this will work. If it doesn't, it is because of the differences between the PC output signal and that of set top boxes (cable or blu-ray players).
I hope this helps.
