Diglloyd.com has long provided HD quality images (2400 to 2880 pixels wide) for a high quality viewing experience in the diglloyd publications. These HD images are immensely enjoyable on 30-inch desktop displays and/or for advanced laptops such as the Apple Mac Book Pro Retina (2880 pixel wide screen).
The expected arrival by mid 2014 of 4K displays with up to 3840 pixels resolution has prompted the addition of Ultra-HD resolution images, typically 3842 X 2568 pixels. These images are very large and slower to load, so most users are cautioned to stick for HD resolution in most cases.
High resolution HD and Ultra-HD images are included in diglloyd publications for subscribers.
