• HDMI and Other Ports: Make sure that the TV that you buy has a minimum of 2 HDMI ports and a USB port along with an Ethernet port (RJ45), component input, composite input, RF input, optical I/O Port, etc.
• Ignore contrast ratio: Though the contrast ratio determines the quality of the picture, manufacturers fudge the numbers. (In general higher contrast ratio, Greater image quality)
