DoubleSight DS-90U


The DoubleSight DS-90U is a pricey portable USB monitor offering good color performance and an adjustable, albeit bulky, stand.

Lightweight. Slim profile. Good color and dark grayscale quality.

Small screen. No auto-pivot. Bulky stand. Relatively expensive.

Didn't work...for me


I would recommend if you had one monitor and an NVIDIA based GPU, but not if you have a dual monitor set-up with an AMD/ATI GPU.

It's a great little monitor, has would be great for that little extra space I wanted

The drivers/software to use this little monitor does not play will with Catalyst Control Center, or ATI drivers....The support in windows 7 is non-existent making it hard to find any support

I love this little guy


Needed this for a stand alone server, works as advertised with windows7, So far have purchased 3 work great for what I needed it to do.

Works great, can boot to it (however you won't be able to access Bios on some computers. Great if you need a very small screen with a home server or other applications. Doesn't need a power supply, powered by USB (2)

uses 2 USB ports, somewhat limited brightness

Works, doublesight labeled it was the 7 inch


Does what you expect. Mini extended desktop on the go

The manufacturer mislabeled the back of the monitor as the 7 inch DS-70u ; Have to install drivers before it works

DoubleSight DS-90U Black 8.9" 30ms LCD Portable Monitor w/USB2.0 200 cd/m2 300:1


I use this for my slingbox, for running Windows media player, and for keeping Outlook open. If you prefer your work space to be dimly lit, then the glossiness won't bother you. Overall a good product.

Portable. Install is a breeze

Gloss finish makes it more like a mirror than a monitor. Reflects lights so badly that I had to move my lamp. Had to crank the bightness to make it visible. Does not match colors with my larger monitor. (Could be the other monitor's fault.)

A handy addition


The unit could add an unpowered usb port to "give back" the one that it takes up. I really would like to see an improved stand design, incorporating a quick release mechanism, or re-engineering the stand so that the sturdy "desktop" stand is more...

The screen is nice and bright, and a good size to complement a laptop or as a utility monitor for a desktop setup. The kickstand is a nice touch for travel, and the included cover does a very good job of protecting the front of the screen. The included...

The kick-stand desktop stand can be a little annoying. The desktop stand uses a threaded knob to secure it to the unit. From the design it is apparent that they didn't intend for the unit to be taken off of the stand frequently... a lack of foresight...

Perfect for my needs


I use this as a seperate monitor for showing clients my screen at "lunch meetings". They can hold the screen and interact. without the weird angle the laptop had to be at for showing ideas, and websites.

Thin ! Thin, but enough bezel. Bright display, and crystal clear. I have it for my MBP13, and in mirror mode it forces my MBP to a lower res, but for my needs, perfect

The only thing that I found so far is how the power USB plugs in. It is at right angle, which helps, but you have to take care not to put pressure on the connection

Running windows 7, the setup went real quick and easy. I ran this on two machines, a quad core desktop, and a 9" 1.6ghz atom acer netbook. On the desktop, it flys, no stuttering, great color and played high def video no problem. As far as the netbook,...

I wrote a lengthy review on Amazon about this monitor, but here's the gist of it: 1. The 9" screen makes a big difference vs the 7" screen versions (about 65% more real estate), 2. The resolution on the DS-90U is 1024x600 which is fine for Web browsing...
