How to play PSP 2000 video on HD LCD TV
A notable/remarkable function of new version PSP is video output. You can output UMD VIDEO or video that was saved on Memory Stick Duo media to a TV using a video output cable. There are four choices for video output cable: D-Terminal Cable (PSP-S170), Component AV cable (PSP-S180), S Video cable (PSP-S160), AV cable (PSP-S150). Here we only introduce how to output PSP system video to a TV using a Component AV cable.
The biggest resolution supported by PSP video is 720×480, coz the built-in LCD of PSP is 480×272. 480×272 is enough if you only watch video on PSP, but 720*480 will be the best choice if you output video to a TV
Steps:
1. Connect the PSP system to the TV using a Component AV cable
(Component AV cable connected with PSP)
(Component AV cable connected with TV)
2. Select ‘Connected Display Settings’ in PSP settings
3. Adjust the following parameters:
TV Type: 4:3 or 16:9
The choice of this parameter according to the aspect ratio of video
* Component/D-Terminal: Progressive or Interlace
All HD LCD TV support ‘Progressive scan’, so selecting ‘progressive’ is ok. Additionally, if outputting the game screen, the television must support progressive scan.
4. Selected ‘Switch TV Out’, the video will display on TV
Note:
New version PSP-2000 only switches built-in LCD display to external TV, so the performance used on big screen is same as the original. Besides implementing outputting video to external in the main menu, you also can press and hold the brightness adjustment button below the PSP system LCD screen for a little long time (that is, press and hold this button for 5 seconds around to access output mode, this is a relatively fast and convenient operation, and only need a lightly flick to exit) besides selecting in main menu to operate. And built-in LCD will not work anymore at the same time.
