After more 1 000 000 (one million) views on forum for 1.5.0.x development versions... and 1.6.1.0, 1.6.3.0-dev versions A new stable version, UltraVNC 1.6.4.0 and UltraVNC SC 1.6.4.0 have been released: https://forum.uvnc.com/viewtopic.php?t=38095 Feedback is welcome
Is it possible to include an option to make the server send compressed grayscale images instead of color? 8-bit grayscale looks (except for the lack of color information) as good as 32-bit color, and might compress better than 8-bit palletized color. For more mundane uses, color information isn't highly important and wastes sometimes limited bandwidth. You could even have the option of 4-bit grayscale for even less bandwidth and "low quality" images (which aren't any worse than the current 8-bit scheme except for the lack of color)
