Very, very nice. As far as preparing goes, I would recommend you download some very impressive looking shmup games. These generally have the most wow-factor graphics, and being arcade games they are designed to be played on a good RGB monitor. Games like:
Pro Gear
Blazing Star
Pulstar
or run and gun games like Metal Slug.
Look into programs that can allow your computer to output 240p to this monitor. Start with Soft 15khz.
