SIIG USB2.0 to VGA External Adapter JU-000071-S1 Resolution up to 1680x1050

Pros: worked for about 10 minutes

Cons: unreliable hardware, and software, horrible tech support. No help, no resolution, and they blame you for the product not working, instead of resolving the problem.

Pros: It works, at least for webpages and office work.

Cons: Not usable for games or video.

Trying to play Windows Media Player on the second display will cause a blue screen on command, so I just don't use it for video.

Pros: easy software install. Hardware is simply a USB conection. Easy Peasy - Lemon squeezy

Cons: None

Other Thoughts: Used on older XP Pro workstations with USB 2.0 ports. Worls great with no noticable video delays at all.

Pros: Nothing to list. If I could give this piece of JUNK 0 eggs, I would!

Cons: THIS THING IS USELESS! I have spent 2 business days trying to get this junk to work in XP, to no avail Their CD sucks, their driver on the website sucks, and the driver that they e-mailed me made things EVEN WORSE! I will be immediately asking for a refund, and if you're smart, you'll do the same!

Other Thoughts: Worst investment I have EVER made.

Pros: I saw the comments about not being able to reposition the monitor but the latest driver from SIIG's website allow full relocatability - left, right, above, below (at least with Windows 7 pro). It just shows up as another monitor in the normal Windows 'change display resolution'.
The other pro is, well, the way you can add third monitor to a laptop after the internal screen and normal external monitor port are used up.

Cons: It is rather slow and windows jerk when being moved around but since I use it for full screen spreadsheet and documents this isn't really a problem. Once you have a 2D app window in position it's OK.

Can't be used as an emergency video card when there's a problem with the built in video because the driver doesn't kick in until the system is booted up.

Other Thoughts: Don't even bother with the driver version on the included CD, just download the latest from SIIG. Be sure to run the install routine before plugging the thing in!

Pros: Would be just "okay" if it worked.

Cons: After initial Install, pc blue screened 4x per day. Called/Emailed/Chatted with Siig and they first said "oops, try this new driver." After that made the product work but did not remove blue screening, contacted Siig again, while pleasant, this time it was "return, as it appears defective." Just give me something that works.

Other Thoughts: Look elsewhere unless you want to waste time. I'm running Athlon II, Windows 7, Asus (unit is about 1month old)...!...

Pros: Adds an additional display at resolutions up to 1680x1050. Fairly simple to install.

Cons: MAXIMUM one device per computer, cannot control "positioning" of the display (it puts it to the left of the primary display).

Other Thoughts: Requires a reboot to initiate.

The fact that I couldn't control the positioning of the display was a killer for me. I have 3 displayes, left to right, with the primary in the middle. I wanted to a 4th on top. Couldn't do it with this. And because I'd have to radically alter my setup and switch which monitor is placed where (because two of the four operate at resolutions higher than this device supports), I had to return it.

Pros: Gives you a second low-res display via usb port.

Cons: You can not re-arrange where the second display is situated. It shows up on the left or the right, as it wishes, you can not drag it to the other side or above/below your main desktop if that is where you want it.

Pros: small, inexpensive

Cons: Doesn't work on XP. I installed the USB VGA device driver from supplied CD as well as from SIIG website on 3 different PCs running XP. Though the device appeared in Displays control panel, I couldn't send computer desktop to that device. The driver isn't MS certified to run in XP. Also, my device says version 2 s/n info sticker while the driver from CD and online says 1.0. In any case, it never sent a signal to an external monitor.

Other Thoughts: This was supposed to be a cheap alternative to a PCMCIA video card for a Dell laptop that has only HDMI video output, no VGA. As it is, that will only connect to a high-end LCD.

Pros: Gives you the capability to add another monitor to your system if you do not have another VGA or DVI connection.

Easy to set up. Make sure you follow the instructions for flawless installation.

Cons: Color quality and Max Resolution is at 1280x1024x32.

A bit pricey, I thought.

Other Thoughts: I purchased this so that I could have 2 monitors set up on my server. I have a 2U server chassis and the other monitor uses the onboard video connection. Even though I have a AGP connection on my MOBO and I could have used a riser card (theoretically) to connect another video card, thus eliminating the need for this USB to VGA adapter, the video card would have not been able to physically fit my case due to the location of my CPU cooling fan.

It is possible to use this adapter with World of Warcraft (yes, I do play WoW on my server!) but it takes some tweaking to get it to work properly. With WoW on my main screen, my secondary is used for checking things out online without having to minimize the game. If you are in this boat, do a Google search for WoW Dual Monitors for help.

I also use this for web design. My scripts go on the second monitor, as color and res are not an issue for text editing, and the browser window is on my primary where I can see the pages as intended.
