A friend has asked me about this - I don't know the answer so am turning to you guys to see if someone knows.

A display at a market using a laptop would be greatly enhanced by the use of a second screen attached to the laptop, that could face a different direction for the public to see. However, there is no power outlet available at the site, so the screen would have to be powered by the laptop.

I assume the laptop is a Windows-based one, but I don't know any details at this stage. I can ask if it's relevant.

Does such a screen exist?

Kind Regards,
Wendy

Yes, they started appearing on the market about a year ago - generally powered via USB. Can't say I've seen them locally though.

e.g.

probably easier to buy a cheap tablet and extend/mirror the display

Running a second screen via USB is gonna kill the battery life on the laptop, and as you say there is no power point nearby

Use a Mimo Monitor (powered via USB). I have a 7" one here and it works well. I bought mine from an Australian distributor a couple of years ago.

The AOC e1649fwu is listed in some local retailers. The Lenovo LT1421 is available as well.

Thanks KevinL, wellgary and Mauricio! Didn't expect such a positive response so quickly - you've made my day. :-)

I'll pass your advice on to my friend.

I would suggest a small invertor, running off car battery to power both a standard LED monitor and the Laptop. Even without an external monitor, the laptop battery won't last long.

$150 from Noel Leeming Here, I personally have used one, While you probably won't be able to game on it just having it display a webpage / document its perfect.

If only one screen is in use most of the time using a blank screensaver on the master screen with a short timeout will help a bit.
