Well, the cost of the monitor is one factor only. Support 10 bit color depth is another. You'd also want one that's fairly accurate but accuracy is dependent on color calibration. If you're editing video it has to be dci-p3, and depending on what dimension of video, you'll want it to support rec709 or rec2020. Thought dci-p3 is the better overall choice because its color range is wider. So if you're editing for the Asian market, one that appreciates bright endless colors, it's a no brainer. If you're doing something studio related for film or whatnot, then rec709 or rec2020 will suffice, again depending on what you're editing. But even if you edit under a dci-p3 schema, your end result won't be the same to what you edited. Now any real professional who'll be doing video editing would want a monitor that addresses all three of these schemas or one good one for each schema. There's a lot of midrange, quality products. There's the more expensive Eizo line and of course there's grading monitors that cost as much as a new Honda Civic. YMMV.
