low prices are pretty nice, but no matter how cheap something is, if it doesn't do it's job it's crap. This adapter physically will not attach. The metal shroud portion of the DVI end is slightly misshapen. I will be spending more money somewhere else to get a product that works.
CONS: the DVI end of the adapter doesn't actually fit anything so it doesn't work
I spent hours trying to get a svideo to component dongle working on an HD 4550. Turns out the Nvidia and ATI dongles have different pinouts. Had one of these lying around and took a chance. It WORKS!
If you are having trouble you may need to do the following steps. Set the dip switches to 720p out only (you can adjust in software later). You will need to have installed the most recent catalyst drivers. You also need to have anpother display with DVI or VGA output. Load up and find the option that says something like "force component output detection" then reboot. Then you need to tell it to output 720p. Then reboot. Not it won't display anything until windows fully loads, i.e. you won't get any bios message or the windows logo.
However once it loads you are golden. perfect picture (I had to set the oversan to 0%, for some reason it defaults to overscan)
On the first one I received the adapter had defective dip switches that were all stuck in the off position. When trying to turn them to the on position the switch broke off. After a quick RMA (great customer support from MonoPrice) I found out the adapter on works on a handful of video cards. I had to end up sending it back for a refund.
Tip: make sure your video card is on the list of compatible cards prior to buying this.
PROS: Cool concept
CONS: Only works on a limited range of video cards
