Screen resolution varies between monitors. Resolution is measured in number of pixels across and down. Laptop LCD screens range from 1024 x 768 to 1920 x 1200 pixels, for a 15" - 17" screen. HDTVs and wide-screen TVs have pixel resolutions varying from 1920 x 1080 (Full HD, 1080p) to 1366 x 768 (HD Ready, 768p).

Unless your desktop computer or laptop screen and TV screen are of the same size, adjust the resolution to ensure the best connection from desktop computer or laptop to TV.

Make sure both screen aspect ratio and pixel resolution of TV and laptop are compatible. You can adjust both picture ratio and resolution from the the Display Settings of the Control Panel in Windows. MacBooks automatically adjust settings for screen resolutions and ratios; if necessary, the adjustments can be tweaked in System Preferences. Please refer to the user manual of your monitor, graphics card, laptop, HD TV.
