The 11.3" inch screen was available as either dual-scan or active matrix. The resolution on the 1400 series was bumped up from the 640x480 of older PowerBooks to 800x600. Many faulted the video as being too slow and with 1MB VRAM video was limited to 16 bit. All of the 1400's offered the cool option of adding a custom back and companies like were quick to supply them. There are two issues to be aware of if you are considering a G3 upgrade for this machine, heat and power consumption. Some have suggested that a G3 upgrade would run too hot in this machine. The other issue is that the upgrade will drain your battery roughly 25-75% faster than without the upgrade. For more information on this issue and the PowerBook 1400 in general visit The PowerBookSource website.
