David Lean’s 1962 Lawrence of Arabia is back in cinemas this week in a new 4K restoration of the reconstructed version (first seen in its entirety in 1988). No, I didn’t know what 4K meant either so I had to draw on the wisdom of the oracles. (I used a search engine.) It’s the pixels, dummy. 4K denotes a resolution of approximately 4,000 pixels wide and 2,000 pixels high, compared to the previous standard of 1,920 x 1,080 pixels. That’s more pixels than you’ve got popcorn in your Mega Meal Deal Bucket.
