Editing Gran Turismo 4 (section)

===Hardware compatibility===
''GT4'' supports [[Dolby Digital]] surround, [[480p]]/[[1080i]] ([[NTSC]] only) and [[widescreen]] modes, however 1080i is only supported in single player races. Despite the lack of online gameplay, ''GT4'' does support use of the [[PlayStation 2]] Network Adapter, which can be used to communicate with additional PS2s to create a multi-screen setup. In addition, the Network Adapter can be used to play games on a local [[subnetwork|subnet]] for up to six players, though player customized cars cannot be used in a LAN game. Support for the [[Logitech]] [[Driving Force Pro]] and GT Force steering wheels is continued from ''[[Gran Turismo 3: A-Spec]]''. Other "PC" steering wheels previously (and unofficially) supported in ''GT3'' were explicitly disabled for ''GT4''. New support is given for [[USB]] storage and print devices used in Photo Mode.
