![]() The remote will be familiar to anyone who has seen an Optoma remote in the past few years. It's possible to connect a streaming stick with power supplied by the USB, but you'll need to run an audio cable (either optical or 3.5mm analog) because neither HDMI port has ARC. On the back of the UHD35 are two HDMI 2.0 inputs with HDCP 2.2, VGA in (YPbPr/RGB), 3.5mm audio in and out, optical out, a USB for power, 12V trigger, and RS232 for home automation control. Menu navigation and image adjustment buttons are on the top of the projector. Both move easily while still feeling firm. The manual zoom adjustment tab is on the top of the projector and focus can be tuned by turning the ring around the lens on the front. The white case measures 4.65 x 12.4 x 10.63 inches (HWD) and weighs 8.77 pounds, slightly less than the UHD30. The projector's chassis is identical to its predecessor, the UHD30. Even more reason to make sure your initial placement is correct. As a note, turning on the Enhanced Gaming mode will disable 3D, aspect ratio, zoom, image shift, and keystone correction. Input lag with a 4K/60Hz signal is an excellent 16.7ms. Anything above a 60Hz signal will max out at 1080p, though, as the UHD35 only has HDMI 2.0 ports (4K/120 requires the larger bandwidth of HDMI 2.1). If you're gaming on a console, the refresh rate will be limited to 120Hz (because of the console limitation, not the projector) with a lag of 8.9ms. Optoma touts the UHD35 as providing a "next-generation 4K UHD home theater & gaming experience." To support that claim for gaming, the projector's Enhanced Gaming mode has the capability for a 240Hz refresh rate (if your computer can provide that) and an incredibly low input lag of 4.2ms at 240Hz. Any further image adjustment is done digitally, which can lead to a decrease in brightness so, as always, use that option as a last resort. Planning your projector placement for the Optoma is important, as it only has a 1.1x manual zoom (you can determine the ideal throw distance using the ProjectorCentral Optoma UHD35 Projection Calculator). If rainbows cause you frustration or annoyance, best to either find a UHD35 to see in person or order from a seller that has a generous return policy. I didn't experience any on my test material, but I'm also not very susceptible to them. ![]() (For more information about pixel shifting technology and comparisons between "True" 4K and XPR 4K, check out our Projector Resolution Shootout.) HDR10 and HLG are both supported on the UHD35, as well as 3D (frame packed at 24Hz if from a Blu-ray player, frame sequential at 120Hz from a PC).Ī drawback of most single-chip DLP designs is reliance on a color wheel-in this case an 8-segment RGBWRGBW color wheel-that can cause some people to see a rainbow effect. Pixel shifting, even TI's version, always brings with it some healthy debate on actual image quality, but at least in the case of the UHD35, the 4K image looks highly detailed and far better than a native 1080p (1920x1080) picture. XPR is Texas Instrument's super-fast pixel-shifting that quadruples the apparent resolution of the native 1080p chip to put up all the pixels in a full frame of UHD video. The Optoma UHD35 has a single 0.47-inch DLP 4K chip and uses XPR (Xpanded Pixel Resolution) technology-also referred to as fast pixel switching-to achieve full 4K (3840x2160) resolution. ![]() Eco will last up to 10,000 hours (almost seven years), or 15,000 hours in Dynamic (a little over 10 years). But even if you're watching the average amount of TV for Americans (28 hours per week according to Nielsen Co.) that's still over two and a half years with Bright lamp mode life expectancy-4,000 hours. Of course, having a lamp means eventual lamp replacement for $249 (you can find retailers on ProjectorCentral's lamp page), that you'll need to tack on to the $1,299 price. It's a bright, budget home theater projector, rated at 3,600 lumens, that can hold up well to some daytime ambient light (although my measurements came in well below that more on that later). In a market that has recently been focusing more on LED and laser light engine technology, the Optoma UHD35 uses a tried-and-true 240 watt lamp.
