![]() ![]() In order to enable 3D on things such as games, you must open apps using the TriDef Ignition app. When the glasses flicked to life, the lenses got a little bit darker, but the screen never flickered, unlike the Acer Aspire 5745DG. Transitioning from 2D to 3D viewing was fairly seamless. An extra pair of glasses costs $99 through HP's site. Unlike Nvidia's solution, the ATI glasses (created by a company called XPand) can't be recharged via USB-you have to replace a watch-sized battery-and there's no light telling you the glasses are on. The glasses weigh just 2.1 ounces and are comfortable to wear, even for those who already wear glasses. It's similar to the technology Nvidia uses, and far superior to the passive display technology (which uses simple polarized glasses) in systems such as the Lenovo IdeaPad Y560d. ![]() A transmitter in the notebook then communicates with a pair of glasses, whose lenses flicker on and off to create a 3D effect. That is, the notebook's display refreshes at 120Hz, twice the rate of most notebooks. The HP Envy 17 3D uses ATI's active-shutter technology to display 3D content. Sound quality was excellent: Voices sounded natural, and the notebook's mics were strong enough to pick up on our conversations taking place off camera as well. While details were crisp and movement fluid, images in fluorescent lighting took on a bluish tint, which we had trouble removing, even with the advanced settings in the MediaSmart Webcam software (where you can also add fun effects and avatars). The Envy 17 3D's TrueVision Webcam can record a max resolution of 1200 x 800. The notebook also has a 5-in-1 memory card reader. Also included is an Ethernet jack, Kensington lock slot, and two headphone jacks, one of which doubles as a microphone connector. The Envy 17 3D's ports include HDMI, VGA, mini DisplayPort output, and three USB ports (including one that doubles as an eSATA connector, and one that meets the new and faster USB 3.0 standard). We liked that you can also tweak equalizer settings using the Beats audio control panel. Not only were sounds crisp and bright, but there was plenty of low-end bass, too. ![]() When listening to music or playing games, we were impressed with the fidelity and power of the speakers. The Envy 17 3D's speakers, which are tucked discreetly onto the front lip of the notebook, are powered by Beats audio technology. We also wish HP included skip buttons on the keyboard if you want to skip chapters in a DVD or Blu-ray, you have to use the touchpad and touch buttons. We were also able to watch movies comfortably from the sides and even with the lid pushed far forward, but that required us to dim the lights with the lights on, the display was too reflective to watch at wide angles. As promised, the display was bright, too, and the colors were true. When we watched Blu-rays on the Envy 17 3D, we were impressed by the level of detail. The notebook also packs ATI's Eyefinity multi-display technology, which lets users connect up to three external monitors, provided one is attached via mini DisplayPort. However, the 3D comes with a higher-res Ultra BrightView Infinity display, which has 1920 x 1080 full HD resolution, wide viewing angles, a 72-percent color gamut, and a refresh rate of 120Hz. That's disturbing.įor the non-3D version of the Envy 17, HP offers a BrightView Infinity display, which has a 1600 x 900 resolution, standard viewing angles, and a 60-percent color gamut. ![]() But after we played Call of Duty for 10 minutes, the left Shift and Caps Lock keys were a blazing 125 degrees. We can accept a fan that blows 120-degree air. The left side of the Envy 17 3D is the real trouble area. ![]()
