Can you use 900x1440 tft without graphics supporting that resolution

Well, you can use a program called irotate if you have a monitor that supports a resolution of 1440x900 (in other words a 17" or 19" monitor) and choose to rotate it in irotate's settings or it is built in to your graphics driver as extra software such as an Intel 845GV/GL/GE chipset. Also it should be enabled on most recent NVIDIA Graphics Cards such as GeForce 8 series. For irotate: http://www.entechtaiwan.com/util/irotate.shtm
