![]() ![]() With Enhanced Gaming mode on, it clocked in at 16.4ms on my Bodnar meter at 1080p 60Hz. The HD146X wasn't designed primarily as a gaming projector, but it offers a short enough lag to satisfy most gamers. You'll be glad for that audio port the 3-watt onboard speaker delivers tinny sound at a low volume, so an external sound system is a must. The only other connectors are a 3.5mm audio out port and a USB-A connector that can only be used for powering an HDMI streaming dongle. Input is limited to a single HDMI 1.4a port. However, this isn't much of an issue for day-to-day use, and may just be a matter of how quickly you release the button. One minor annoyance I ran into while using the included remote control was that the menu highlight often jumped two steps in response to one button press. ![]() I set it up for a 90-inch image at 9 feet, 8 inches from the screen using the maximum zoom setting. There's also a +/- 40 degree vertical keystone control to square off the image if you need to tilt the projector to aim at the screen. Set it in place, adjust the manual 1.1x zoom, and focus. The HD146X weighs only 6.2 pounds and measures 4.3 by 12.4 by 9.5 inches (HWD), making it easy to handle. The HD146X's wheel is red-yellow-green-cyan-white-blue (RYGCWB), with a white panel to increase brightness, and yellow and cyan panels to help minimize the color errors the white panel causes. ![]() Like them, it has a six-panel color wheel. Unlike its head-to-head competitors from BenQ and ViewSonic, which have 1,920-by-1,200-pixel DLP chips used for 1080p resolution with room for image shift, the HD146X uses a 1,920-by-1,080-pixel DLP chip. And when all three are compared as they come out of the box, without setting adjustments, the HD146X delivers the best balance of color accuracy, contrast, black level, and three-dimensionality for video and movies. However, it has the same 3,500-ANSI-lumen brightness rating. Most notably, it has only one HDMI port instead of two, and there's no image shift to match the picture position to the screen for easier setup. Compared with other entry-level projectors, such as the BenQ TH585 and the ViewSonic PX701HD, it lacks a few features. The Optoma HD146X ($549) is Optoma's least expensive 1080p home entertainment projector. ![]()
