Showing A4 Or a rotated 19" screen. Actually I can read even small-print "letter"/A4 document using FoxitReader quite adequately on my 17" 1280x1024 without rotation if I scroll,. So i don't see your problem. OK my endocrinologist has an ultra-wide that can display two pages side by side, one of text, the other graphical, or perhaps data+a form. I can imagine some photo-editing that will make use of an ultra-wide: while GIMP has tear-off menus & sub windows that can use a second, independent screen, other tools like Darktable use attached side panels that aren't 'tear-off', so a wide screen is useful. I suppose there are some authoring tools, book-level, where you need to keep track of sources, characters, timelines, subplots etc where a widescreen is useful if it can't handle tear-off to a second screen. But that's specific.. Unless you have a specific app in mind, specific demands, I can't see any need for a 30" screen just to read an letter sized, A4 document. After all, how large is that? Two side-by-side full sized letters are what? 18x12, that's a 22" diagonal screen. I'd be more concerned about pixel density. Well, I've just fired up FoxitReader in 2-up side-by-side of a letter-sized PDF at 65% to get the full sized page both in total view, along with the menu bar and location bar of FoxitReader, and both pages at 10pt are readable on this 19" LG Flatron W1942TQ at 1280x1024. Native mode on this is a little wider. So I don't see the need for a 30" screen just to view A4 pages. -- “Reality is so complex, we must move away from dogma, whether it’s conspiracy theories or free-market,” -- James Glattfelder. http://jth.ch/jbg
