Sub £200 For computer and XBox

[TooManyCables]

I'm looking for a monitor for my Macbook pro (and a PC), but also XBox. Around 24-27 inch. At least one HDMI input, Good speakers built in (most don't) or be able to plug in speakers.

For hopefully less than £200.

I've looked but either the built in speakers are terrible, or you can't plug external speakers into them.

Any suggestions?
