No trip to mainland Europe is complete without taking a look at Teletext. I found this set of test pages on DR1

(Subpages 5-7 were just a blank page with red, green and blue backgrounds respectively)

teletext page 744 on DR is a test page in Swedish that displays one of each character, a simple graphic, a “clock cracker” made out of two lines with alternating blocks and ü characters, samples of coloured text, and blinking and double-height textthe second test page has “the quick brown fox jumps over lazy dogs” repeated across the entire screen, with a diagonal line of “01” cutting through itthe third test page is a full-screen “clock cracker” with alternating columns of solid block characters and ü charactersthe fourth subpage is a “konvergenstest” showing a grid of meshed horizontal and vertical lines
