First off a glossy monitor is a personal preference as is a lot of other monitor qualities. So that is a 21.5" display at $140 with $10MIR. The 1ms response is almost an arbitrary number anymore. When it comes down to true response time that number will not apply at all. Most modern LCD can be used for gaming without any ghosting issues at all. So pretty much forget that number and count on the reviews people write. For video editing and gaming you will benefit from a larger display. Below is a nice display, but for $150-$160 you can get a 23" that is really nice and would fit you perfect. Forget that 1ms refresh rate.
Here is an IPS 23" DELL for $150 after code...
