The highest resolution supported by the Barco CNWU-81B is 1920 x 1200 (WUXGA). That's over seven times the resolution of the most common graphics resolution of 640 x 480 (VGA). Across all projectors of a comparable spec and age to the CNWU-81B the worst resolution is 640 x 480 (VGA) and the best is 4096 x 2160.
We compared this projector to all the other data projectors that support a resolution of 1920 x 1200 (WUXGA)|640 x 480 (VGA) and we think the CNHD-81B, and the CNHD-81B both from Barco which is cheaper is also worth considering.
If the resolution of this data projector is too low for you then you might want to consider the NEC PX602 ($8,137.00) (640 x 480 (VGA and cheaper)|800 x 600 (SVGA and cheaper)|1024 x 768 (XGA and cheaper)|1280 x 1024 (SXGA and cheaper)|1400 x 1050 (SXGA+ and cheaper)|1600 x 1200 (UXGA and cheaper)|1920 x 1200 (WUXGA and cheaper)|2048 x 1080|2560 x 1600 (WQXGA and cheaper)|4096 x 2160 and cheaper), or the Barco CTHD-61B ($9,350.00) (2560 x 1600 (WQXGA and cheaper)|640 x 480 (VGA and cheaper) and cheaper).
