AOC e2251Fwu Monitor (22-inches)


The AOC e2251Fwu adds a USB-powered 22-inch, 1080p display to your desktop, but it's not very portable.

The $199 AOC e2251Fwu Monitor delivers bright, detailed video and images (as long as you avoid using the optional base stand) without requiring AC power. And thanks to the matte display, the monitor's viewing angles are comfortably wide for...

AOC E2251FWU USB Monitor


Today we are taking a look at a new monitor from AOC that is USB powered. Our concerns are that if this unit is able to play fast games, what type of picture quality can we expect, etc… so let's get on with this review. About: Read more on their...

Slim ; Good picture quality ; No lag or ghosting ; No backbleed ; No AC adapter required ; USB Powered

Flimsy foot

You can pick this monitor up for 150$ on the market, which is a tad higher than some cheap 24″ screens sell for at the moment. The thing is that this is portable and therefore the 22″ inch is worth it. It is very nice quality, easy to use and even...

AOC E2251FWU 22in USB Monitor


A USB powered 22in Full HD monitor. Smart, yes. Practical? We're not so sure.

Plug and play setup, Largest USB powered display, Discrete design

TN panel cannot match IPS displays, Not fast enough for gamers, No adjustment with or without base

AOC E2251FWU review


AOC's E2251FWU is a 22in Full HD monitor that receives both power and video over USB, so is an ideal companion for a laptop or a PC without additional graphics ports.

A handy product for extending your laptop's work area

AOC e2251Fwu monitor review


Here's an interesting concept in lightweight monitors, strip it right down to the basics and make it as light and portable as possible. That means getting rid of the usual separate power supply for a 22” (21.5” viewable) LCD, backlit TN panel and...

If you need an ultra-lightweight LCD display to lug around with you then this is the monitor for you. You won’t find lighter or more portable with just one wire connection and no need to find a power supply. That though is the E2251F’s niche, because...

I love this, one cable and the picture is great. Not for gaming but if you need email or many things open at the same time its a great deal. I have 4 monitors connected to a laptop, 2 using USB interfaces and they work great. This unit being only USB...

Excellent - Couldn't Be Happier


Works as advertised. Clear, clean image and only one USB cord. No additional power cord needed. It has a double USB (two-connectors) but my HP laptop had enough power in just the one USB port to drive the monitor. It is thin and very lightweight. I...

Excellent Monitor for 2.5 Watts!


I have had mine since first availability in May. The image is very clear and even and suitably bright. My two issues: the stand is a bit flimsy (slight desk movement causes substantial side-to-side display rocking), and the DisplayLink driver does not...
