Monitor for HD video editing

"I think it should depend on your target. If you work in standard sRGB gamut most of the time, the U2410 or the old 2407WFP is a good option. If you want more NTSC gamut/AdobeRGB gamut like editing, then consider the HP LP2475W, Dell 2408WFP, the LG W2600HP (not H) or the NEC 2690WUXI.
All screens mentioned here are IPS based, thus stable images with accurate colour, except the 2408, which is a S-PVA display, another high quality panel type, used by most Eizo's.

You can also consider some 30 inches with 2560x1600 pixels. They are not so great for 1:1 full screen pixel viewing, but they have plenty of room for editing panels next to a 1:1 fullHD preview! The LG W3000H, The DELL 3008WFP or the Samsung 305T is a good deal for a 30 inch S-IPS/S-PVA wide gamut display, the old DELL 3007WFP is standard gamut."
