After reading people had issues after buying cheap versions, I decided to buy this cable and so very happy with the results. You get what you paid for and here its gorgeous HD gaming.
No difference in quality between this and when I'm connected via HDMI to my led tv.
This cable however does not have the optical port that the previous version had, which is no biggie for me.
Comes with a stereo Y adaptor converting the RCA connectors to a 3.5mm jack.
The VGA cable let's you select almost every resolution supported which you can't do with the component cable. Selecting the correct resolution for your monitor/tv is very important to ensure that you monitor won't be rescaling the image. This is why the VGA cable will offer less jaggies than the component cable.
The cable also comes with 2 adaptors.
You should always go oficial when it comes to console accesories.
I bought this about a year & a half ago and have been using it ever since. If you're looking for a cheap way to play your xbox 360 in HD and don't want to fork out hundreds for a HDTV, this is a must buy. I was using it with a 15" Monitor which I also use for my computer, but have since upgraded to a 22" LG Widescreen Monitor and it's impeccable. The picture quality is superb, the same as a HDTV, and for just £17.99 you really cannot go wrong. It is worth buying a bigger monitor such as a 22", but at just £134.99 for a top quality one, its really not a problem. The only slight downside is that you need to buy speakers which the audio leads from the cable can plug into, other than that its a straight 5 stars.
I bought this due to the poor picture quality of the Component HD AV Cable that came with the console. My TV isn't HD, but this has improved the picture dramatically. There is a small loss of colour, but I just adjusted the screen settings on my TV to fix that.
I would recommend that you buy this cable even if, like me, your TV isn't HD. Its definitely worth the money and makes playing games like Call of Duty a lot easier.
