Works Great Most Of The Time
And by most of the time I mean that as long as the game is at the full resolution it's great. Let me explain. You have a 360 set to 720p. If you play Halo 3 for example which runs at 640p you'll get these bars to the left and right but all the menus are 720p. This could just be my monitor (a 19 inch LCD that came with my Dell Inspiron 530.) But in 480p it works great. To run some Wii games or GameCube games in 480i you have to flip the switch on the box to 1080i mode, and I have yet to get it to work with a PS2 but it never said it would. A great product highly recommended.

Works great.
This box is perfect for use with the Wii, 360, PS3, and PSP. I've tested it on all those consoles and have not had a single issue at all. The only downside is that it doesn't work well for anything that needs 480i, of course since that isn't a supported resolution. I haven't tested it yet, but I believe if you set this box to 1080i and try to run PS2 on a monitor that supports interlaced it will allow you to play. My monitor displays images with this box using 480i, but there is a little dialog that bounces around saying "Input out of range!". This is the only reason I give it 4 stars instead of 5. High recommend this box.

Working perfectly.
I am using a spare CRT monitor and connecting my Wii through the XCM box to this. Working perfectly at 480p and not a problem encountered so far.

The Wii proved a slight annoyance in setting up as it would not allow you to select 480p output until the component cables are plugged in, and not having a HD tv I had to insert the green plug into the yellow video on a standard def tv and change it then plug it all back into the XCM box.

But besides that it is working perfectly.

Works as advertised but..
Been using this on a Wii and Samsung 19" LCD, the picture quality looks really good. However, have to avoid using the supplied cables at all cost.

Using the supplied cables, noisy lines are very apparent on black backgrounds or during the startup screen of the Wii. Spent some more dough for the official Nintendo progressive cables and the noisy are gone.

Also once in while, the box will get out sync thus causing a blank screen for about second or less but not too much of a problem unless it happens during a critical moment in gameplay.

One last quirk I have is that the VGA input is the wrong gender. It should also be a female type connector....had to get a gender changer for my VGA cable in order for my computer to connect to the box.

Overall good product and quite happy with it. Saves the trouble of having to buy a LCD TV. Only wish the gender changer was included and the supplied cables were more of a higher quality grade.

Lines
Haven't had success using this item. It creates wavy lines across the entire screen, have not found a way to get it to work and not sure if its defective or just not a good item.
