Nope. Take out your magnifying glass and look: each pixel is either red, green, or blue, even in monochrome mode. Those are not software-controlled filters; they're formed by a fixed physical diffraction grating. Monochrome mode just tells the software to set R=G=B, but with the backlight on only one of those three is actually displayed at each pixel. (This may just be a miscommunication, but we might as well be clear.) One amusing question is: could software potentially set monochrome mode and then use fancy color-adaptive subpixel rendering to do optimized display of fonts and images? Maybe, but at 200 dpi the gains would be small, and the computational overhead would be huge. - --Ben -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFIEXH7UJT6e6HFtqQRAiVKAKCdNl5z/A5scDGndbPHZ1Xvn0LOlQCfSDGP BBDUVl4Ybh2emEb8tVVczmQ= =x4XP -----END PGP SIGNATURE----- _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
