I'am considering buying an Electrohome 4100. ECP 4100 peak lumens: 725 Contrast Ratio: 15,000 Horizontal Scan Rate: 15-80 Vertical Scan Rate: 45-120 RGB Bandwith: 65 Max Resolution: 1280x1024 I want to watch HDTV, play XBOX and PS2, Watch regualr digital cable, and finally DVD's. Will this projector be able to support all these? Is the 1280 resolution good enough? Contrast ratio good? PS: I'm a NOOB!
