We have a 1080P TV and an original Xbox with HD. It requires AC it is supplied. The HDMI cable is cheap, we advise you to buy a better one. Therefore 4 stars, not 5. The price is not bad, around 30.00 does what many others cannot. This gives a clear picture. And it does. Its clear and pleasant color. There are no delays. The device, like the switch, is made of cheap plastic, so careful handling is highly recommended. We just plugged it in, turned on the game and that was it. No problem. It actually lets you play in widescreen, which is nice. If you're looking for something that works, this works. Is it ideal, no.
