I was sorting out a load of surplus electronic gear that has not been switched on for over 3 years and among it are three perfectly working TVs that I can no longer use, because the TV signal transmitted in the UK is now digital only and these only have analogue tuners.
About 90% of the material I edit is now originated in high definition and as every UK broadcaster demands that all new programmes are supplied in 1080i I find it hard to watch anything that is not transmitted in HD any more.
I have now started to produce 4K (4096x2304 pixel) video from time lapses shot on a Canon 5D MKII (which are available through the London Photo and Video time lapse gallery). I have nothing to watch them back on yet but 4K TVs are becoming available and PC monitors have been close to this resolution for a while; I expect Apple retina displays will soon reach this level. With the 4K shooting Red Epic and Scarlet cameras becoming widely available more 4K material will be originated and the demand will increase.
The format is likely to remain 16:9 so my LCD and LED 1920p TVs will still be able to show downsized 4K material so hopefully they won't be redundant to quickly. But I doubt they will last as long as one of the TVs I need to get rid of - a Sony Trinitron bought in Hong Kong over 25 years ago and still giving a great picture.
Maybe I will just keep hold of this one a little longer.
