I have an Acer Aspire 6930 with Nvidia 9600m GT GPU, there is a weird issue that occurs when I connect the Acer Aspire to an LG TV with HDMI cable... the Laptop recognizes the TV and everything seems to work but there is no display showing on the TV. I accidentally discovered that whenever I disconnect the charger from the laptop, the HDMI works fine while using laptop over battery.
So what I'm asking is are there any settings that I could change so that HDMI works while plugged in?
