In live events, we use non-standard, wide aspect ratios all the time. 3:1 (three times as wide as it is tall) is not uncommon.
Now, LG Electronics has released two extra-wide LCD displays. The LG “Stretch” series introduces 29″ and 38″ models, with aspect ratios of 2.85:1 and 3.43:1, respectively. They feature RGB and DVI inputs, and RS-232C control. Resolution on the 29″ model is 1366 by 480, and the 38″ model is 1366 by 398.
Designed specifically for signage, I expect these displays will be popping up in retail and hospitality very quickly.
For events, they’d be perfect for digital agenda signage as well as delay screens for widescreen shows.
