Exactly. Alot of TVs wont allow max resolution from the VGA port, so if one has a 1080p TV and wants 1920x1080 resolution you need to use you TVs HDMI port. TV deticated HDMI will squeal and pop if it dont find a video and audio feed through the same cable. Luckily mine has 1 HDMI for video and sound and one HDMI for just video.
