My journey in DATV and the future: 4K UHD or internet-linked DATV repeaters; Not that crazy? Draft In this post I want to briefly outline my DATV journey and a quest for Full HD DVB-T. I have achieved this in a relatively short time and out of some of my difficulties, have wondered if first, 4K UHD DATV and, second, network-linked DATV repeaters, are possibly not that distant. In this post I will outline my journey, as the future is path dependent, history matters! In the following two posts I will consider ways to achieve 4K UHD and internet-linked DATV repeaters. My DATV journey: Live Full HD DVB-T Personally, coming late to DATV at the beginning of 2013, with a 40 year break in my amateur radio activities (see my first post), I have not had to put in the extreme effort and expense of either analogue TV or digital TV, particularly over the last decade, such as by the DATV Express team, among many others. Before returning to amateur radio I had spent considerable time and...

Computer monitors: Beyond Full HD- 1920x1200, 2K-2560×1440, 4K-3840 x 2160 I have used a series of computer monitors with a resolution above Full High Definition: 1920x1080. The obvious question is why? The highest resolution for most movies is 1920x1080. The answer is simple; I don't watch movies on a computer but read a lot; web pages, books and magazines. The higher the resolution the better! The high resolution gives a better quality display of a PDF document. PDF originally was a printing format and generally has a higher resolution than a computer monitor can display. Printers typically can print at 600 or 1200 dots per inch, about ten times higher than a video monitor. LCD monitors produce their best display at their native resolution, anything less usually looks bad as there are not enough pixels to give a sharp image. Try lowering the resolution of your own monitor and you will see what I mean. Ultra high resolution has been picked up by tablet manufacturers, p...
