Thanks to a couple of friends of mine I caught this particular headline today:

I find this curious since the standard TV set I reviewed King Kong 360 on, had no problems what-so-ever and wasn't too-dark at all. Nor have I had a problem with any of the other games.
So I conclude that this must hit a small percentage of gamers who do have older standard TVs. Or there's something else going on behind the scenes.
It will be interesting to see what Microsoft have to say on this particular matter, since it certainly hasn't affected my version of King Kong 360 nor the console and the other two TVs that were standard, and on hand to test.
They were fine as well.
