QVGA is 240 x 320, then WQVGA is 240 x 400, or 240+ x 400?
Answer
From Wikipedia:
Wide QVGA or WQVGA is any display resolution having the same height in pixels as QVGA, but wider. This definition is consistent with other 'wide' versions of computer displays.
...
WQVGA resolutions are common used in touch screen mobile phones, such as 240×400, 240×432, and 240×480. Other devices like Apple iPod nano uses a WQVGA screen, 240x376 pixels.
