Connecting you TV through HDMI cable should not give you a lot of trouble, this is if you are using straight cables (Hdmi to Hdmi), if there is another device between them it won't work, in other words, video cable adapters do not work. Always use straight cables.
Make sure you are using updated graphics drivers, they are available at http://www.intel.com/support/graphics/detect.htm
Also, see if you can install monitor drivers, contact your TV manufacturer and get latest monitor INF drivers.
