USB 2.0 UGA Multi-Display External DVI Video Card with VGA/HDMI Adapters (1920*1080 Max)

Pros: Build quality is very good Full retail packaging as pictured - even shrink wrapped. Includes DVI - VGA and DVI - HDMI adapters Working well. Running at 1280x1024 VGA for a third monitor with a Dell Precision laptop and docking station (plugged into docking station). Very little lag in desktop applications - haven't tried any form of video or games but didn't buy it for that. Video quality at 1280x1024 75Hz is fairly good - at 60Hz it wasn't great for some reason. I'd prefer to use DVI but the LCD I'm using at the moment is not capable of that.

Cons: Whilst it didn't ask to reboot when I installed the drivers, it gave an error saying it "couldn't write the device". The manual said unplug and plug it in again but that did not work. Rebooted and all was working fine after setting up resolutions etc again. Changed the display numbering order after the reboot (it became display 2 and the docking station external display became display 3). None of these are really that much of a con though.

Other: Maybe a little expensive but is good quality compared to some of the DX stuff I've bought (admittedly much cheaper)

Pros: (1) Small form factor, compared to other devices (like Matrox Dual Head To Go) which do the same thing. (2) Ease of installation - drivers downloaded from product website. (3) Excellent build quality. (4) Optional adaptors included - for DVI/HDMI/VGA (5) So far I have not experienced any latency with in image updating, though I would not use this in a gaming monitor.

Cons: (1) Could not configure my monitor "numbering" precisely the way I wanted, but can live with this.

Other: Very useful device to extend your screen real-estate, at comparatively low cost.
