Will that be fine for the resolution the xbox uses?
That's my recommendation too.I would go with this monitor
As stated in another thread:
I have used plenty of Samsung monitors and have had no issues. Every manufacturer has some 'dud' models that seem to skimp on something quality-wise here and there - especially considering budget TN models. Samsung's new models are some of the better built at the moment. If you were to avoid every manufacturer where some people have had issues with particular models you'd be out of luck buying anything at all.
Ah, in that case you will want to get a XBox 360 VGA cable.
I'm not sure what the maximum resolution for this is. VGA is capable of 1080p, but i'm not certain if the Xbox limits it.
May I ask what sound output device you will be using?
