Dell is obviously taking the 4K/UHD transition seriously and it currently offers five UHD monitors, along with a '5K' 27-inch unit.

Dell's latest UHD models started shipping in Europe late last week.

Dell Professional P2415Q replaces last year's Ultrasharp model?

The Dell Professional P2415Q is a 24-inch 3840x2160 monitor rated at 300cd/m2 and 1000:1 static contrast. The response time is 6ms.

The monitor is based on an IPS panel, supports 4K at 60Hz and packs HDMI (MHL), DisplayPort 1.2, Mini DisplayPort 1.2 and DisplayPort out. There's a 4-port USB 3.0 hub on board too, along with a 100x100 VESA mount.

We found it listed in Britain for GBP 362, which translates into about €435. We do not know the official price yet. Judging by the spec, it should replace the old UltraSharp UP2414Q.

Dell Professional P2715Q offers similar spec

The Dell Professional P2715Q is essentially just a bigger model, with a 27-inch IPS panel and a very similar spec - 300cd/m2 brightness, 1000:1 static contrast, 6ms response and the same range of connectors.

Unlike the 24-incher, this model is already shipping in Germany and the asking price is €699. This doesn't make it the cheapest UHD monitor out there, but then again it does have an IPS panel and a few other goodies.
