Looked similar to this one: 720p HD-ready Samsung HDTV I bought with my 360 back in 2005. For like 1.200 Euro or so xD
This was me as well. This was the TV they used in all the Xbox 360 demo pods in the UK, and it was - for a time - the de facto "OMG THE FUTURE IS NOW" display. I dread to think what I paid for it, since I was in university at the time, but it definitely wasn't cheap.
I remember having it delivered, plugging in the component cables, playing PGR3 at 720p, and feeling like graphics were never going anywhere further. And while PGR3 is still quite a nice-looking game in many respects, obviously I was very wrong there.
This was also the TV that put me off Samsung electronics for life. I had to have the power supply replaced TWICE, the speakers would randomly cut out, and a bunch of other issues arose in the time I owned it. But for that initial ownership experience alone, that picture still brought back a lot of fond memories.
