Both Acer and Dell (under the Alienware brand) showed off new 23" 120Hz LCD panels that are compatible with Nvidia's 3D Vision. We got to try both of these monitors out at their respective meeting suites.Previously, the largest 3D Vision capable monitor you could buy was a 1680x1050 22" Samsung display, which forced you to choose between gaming in 3D and full HD. But both Acer and Dell's monitors run at 1080p, making paying a premium to adopt 3D Vision a bit easier to stomach.
The Acer display shown was the GD235HZ version, which is the 23" version of the previously announced 24" GD245HQ monitor. Basic specs include 2ms response time, 80,000:1 contrast, and 1920x1080 resolution.
Dell's OptX AW2310 monitor looked very similar (both probably use the LG 120Hz TN panels announced in December), and boasted 400 cd/m2 brightness.
But there's still one limiting factor neither of these makers have addressed with these monitors: robust input support. Both monitors only have single HDMI and DVI ports (though the Dell also has 4 USB ports), making them less than full-featured. We're still waiting for a 1080p 3D monitor with multiple HDMI and Component inputs (and a decent internal scaler) so they'll also work as game console displays.
Acer hasn't announced a price for its GD235HZ, but the Alienware OptX AW2310 is now for sale on Alienware's website for $649. Ouch.
