When you open the Qosmio G20 there is no way to escape the big impression its large 17? widescreen LCD will make on you. The picture is really clear and crisp, and the size of the screen (1440x900 WXGA+ and up to 2,048 x 1536 on external monitors) gives lots of space to work on. The graphics controller is a NVIDIA GeForce Go 6600 Graphics with 128MB DDR video memory.The built-in TV Tuner can receive channels from an internal antenna, CATV or an external antennal, with an autoscan function from 41MHz to 860Mhz.
