Dell has released a pair of 27" monitors today, one of which may be of interest to the gaming crowd around here. Let's start with that one.
The Dell S2716DG is the company's first gaming-oriented monitor, packing a 2560x1440 screen with a 144 Hz refresh rate and G-Sync variable-refresh-rate technology. Although Dell doesn't specify the type of panel it used, the 1-ms response time makes it likely that it's based on TN tech.
Connectivity options are plentiful: the S2716DG has DisplayPort 1.2, HDMI 1.4, four USB 3.0 ports, and both line and headphone outputs. The stand not only has height and swivel adjustment, but can also pivot into portrait mode (a somewhat questionable feature, given that TN panels' weak spot is the vertical viewing angle).
If that all sounds good so far, let me ruin your day with Dell's suggested price: $800. That's enough for you to get Acer's IPS XB270HU and still have a Benjamin left for your next GPU upgrade. The S2716DG will be available on Dell's website on October 20.
If you prefer something curvier, Dell has also announced the SE2716H. This model paints a different stroke with its 27" curved screen. Dell hasn't released detailed specifications, but given its $400 price tag, we can make an educated guess that it's a 2560x1440 monitor with no variable refresh rate technology. Looks pretty nice, though. The SE2716H will be available September 15 directly from Dell.
