This part is a bit different: no astronomical drops in price, just more year on year for the same money.
Pre-PC, my Commodore PET came with its built-in mono screen, 9”, 40×25 characters. Then my BBCs were coupled to the default Microvitec Cub 14” 1431 colour monitor.
On to PCs. My Dell came with the optional VGA monitor, resolution 640×480 pixels, when many users were still using EGA (640×350) or CGA (640×200). My next three monitors were all 15” VGA, costing around £200-250. The next step up was my 1995 Christmas present to myself, a lovely Idek 17”, offering a superb 1280×1024 resolution. It stayed on the books until 2001 and was a joy to look at.
Then the seismic change. November 1999 saw my first purchase of a TFT (flat screen) monitor, a 15” Panasonic LC50S, 1024x768px. As it was an ex-display model I got it for ‘just’ £637. Two more 15” screens followed, Nov 2001 (£385) and Aug 2003 (£205), then a 19” Benq FP91V in Oct 2005 for £257. Then in April 2007, a year before emigrating, these were replaced by a pair of HP W20 screens for £144 each.
On coming to Australia I started with a couple of Samsung monitors 22”/24” each costing around A$300 (say £150). Surprisingly one failed after a couple of years and was judged beyond economic repair. I’m writing this looking at a 2015 27” LG monitor which I plan to keep for a good few years yet, supplemented by a Hisense 43” 4K TV which serves as a second screen and is used for 4K testing.
So unlike some of the other posts in this series, perhaps not much to see here? A 1990 time-traveller would be dumfounded by 2TB drives for little more than pocket money; as for today’s monitors, polite appreciation at best?
