I picked an HD27HDR to replace an older HD26 that I had been using. The one that I received does not have any issues with color wheel noise, but it also only has a single HDR setting unlike what was said in the comments above. Not sure how to get new firmware update as it is not listed on the Optoma website.
Although it currently works with PC games only, the Xbox One also supports 120 Hz 1080p, and Xbox games are on the way. When the HD27HDR is connected to a 4K video source, it automatically establishes a connection at 3840x2160. And with 4K material, all the comments above about SDR performance hold true.

As soon as the image changes again, the projector immediately goes back to the brightest Eco+ level. That said, the HD27HDR is an improvement over the HD26 in all ways. In 1080p SDR mode, the colors are deeper, the contrast is better, and I don’t get the pumping that I was seeing with the HD26. There is still a bit of banding evident, but much less than before. Also, rainbow effect is much less - I used to notice it once in a while on the HD26, but have not picked it up once on the new projector. I found the ‘gray’ screen setting useful to help with making the picture optimized for my 100” ALR screen.
Support for 144Hz rapid-refresh rate provides ultra-smooth flicker-free images. I am comparing the Optoma HD27HDR to the Optoma GT1080Darbee. Is there a noticeable difference between these two. It would seem the short throw GT1080 would perform better in lighter ambient situations with it being a shorter distance to the screen.
Optoma HD27HDR Projector Review
After peeling the protective film from the top of my new ceiling mounted HD27HDR, I inadvertently peeled a small round label from the side. Then noticed the fine print "Warranty Void if removed". I saw no instructions about care and removal of protective film, labels. Didn't notice it until the projector warmed up and caused some small bumps in the film. No warning about the small "Warranty Void" label either.
You can ignore it as a factor when choosing how far to put the projector from the screen. Check the wind forecast for Gunzenhausen when you search for the best travel destinations for your kiteboarding, windsurfing or sailing vacations in Germany. Or use our wind forecast to find the wind speed today in Gunzenhausen or to have a look at the wind direction tomorrow at Gunzenhausen. Some of these Bavaria professionals work entirely on their own, while others work with subcontractors to get the job done. 1080p (1920×1080) resolution renders sharp and detailed images from HD content without downscaling or compression, which is perfect for movies, TV shows and gaming. Display true 3D content from almost any 3D source, including 3D Blu-ray Disc™ players, 3D broadcasting, and the latest-generation game consoles.
Optoma HD27HDR Connection Panel Inputs
Optoma projectors are capable of reproducing the Rec.709 color gamut, the international HDTV standard to guarantee accurate reproduction of cinematic color exactly as the director intended. The projectors can also create saturated colors, great for gaming and animated movies. ANSI LUMENSis the most commonly accepted industry standard brightness measurement. The ANSI lumen rating measures the brightest white that a projector can produce by averaging nine light meter measurements taken across the projected image. Jordan, many 3D projectors have a 2D to 3D conversion mode, but the effectiveness of this feature varies greatly with the content as well as the execution of the engineering.
The game system is Xbox one and the media driver will be a fire stick. I have had minimal chance to do much viewing in HDR. I have played a few games through my PS4 pro on it. Lag is unnoticeable, and HDR mode makes the colors/contrast even better in AC Odyssey. Even For Honor looks great in 4K SDR mode (doesn’t support HDR) as compared to 1080p.
Beyond that, the Full 3D and fast input lag is a major advantage over today's 4K models, most of which have input lags of 50 ms or more. The HD27HDR may well be your preferred choice while you're waiting for 4K projectors to catch up on these other features, or just waiting for them to drop in price. Colors for all but one SDR color mode are well within a realistic-looking range with default settings, despite side-by-side comparisons with a reference image showing slight, but varying, levels of blue bias. The exception is Bright mode, which has an obvious green bias for photos, video, and film. However, that's true of the brightest mode in most projectors.
Of course, what makes the HD27HDR notable is that it will let you take advantage of HDR with 4K HDR material. So the really good news is that it handles 4K HDR nicely. The HD27HDR doesn't offer a setting to force a 1080p connection, so you have to set the video source instead. Probably the best approach is to leave the source at 4K unless you're seeing a problem. But if you switch the video source to force a 1080p connection, don't forget to switch it back. With another, I saw occasional momentary dead stops in movement, possibly because the projector couldn't keep up with the incoming data.
There is no doubt though that the HD27HDR is a much brighter projector . That can sometimes be a plus or a minus depending on your viewing conditions and application -- a much brighter projector may sacrifice some black level/contrast in a dark room for the benefit of more punch. On the other hand, if you view in high or modest ambient light the extra lumens are a big plus and you may not notice differences in contrast. That ability to view HDR content is something the BenQ 2050a cannot boast. The support for 4K input and HDR—including the 1080p HDR modes on the PS4 and Xbox One S—makes the HD27HDR a compelling choice in its price range. It will let you take advantage HDR's rich color and boost in contrast without the budget you need for a true 4K or pixel-shifting 4K projector.
When I set the player to connect only at 1080p, movement was appropriately smooth. With a third disc, colors were noticeably different between 4K and 1080p connections. And with still another I didn't see any differences.
For converting between wind speed units such as knots, km/h , m/s , and mph use our wind speed calculator. Turn on the projector directly from the power source. This feature aids installations that rely on power-on timers.
Enhanced Gaming mode isn't available for 4K input, but the 33.1 ms lag with Enhanced Gaming mode off is fast enough for all but the most serious gamers. The HD27HDR handles 3D better than most projectors. I didn't see any crosstalk in my tests and saw barely a hint of 3D-related motion artifacts. The result was much smoother motion in scenes that tend to show those artifacts than with any other projector I've tested. Like most Optoma models, the 3D is switchable between supporting DLP-Link and Vesa RF glasses.
No one should expect to be able to consistently turn 2D content into a great 3D experience compared with content that has been carefully crafted by the content creator for 3D. If a projector has no keystone correction you must mount it in a location that avoids having to tilt the projector up or down. In a ceiling mount, you'll have the projector facing directly toward the wall on which the screen is mounted and use the vertical lens shift available in the projector to get the image framed up on the screen. If the combination of the native vertical offset plus the available shift still places the image too high, you would have to use a pole on the mount to get the projector a bit further off the ceiling. Otherwise, your only option would be to tilt the projector down, which would cause keystone distortion that you would have no mechanism to adjust out. The 1.1x zoom isn't enough to curtail brightness significantly at the telephoto end of the lens.
Adding HDR and the ability to accept 4K input makes it even more of a value, and unique for its price. DLP is a proprietary technology from Texas Instruments™ that offers digital projection with higher contrast, faster response time, good pixel structure and virtually no color degradation. Cinema and Film modes are also similar to each other, with Cinema being the brighter of the two. However, Cinema also turns some colors—like bright, saturated yellow as seen on a reference projector—into pastel shades. Reference mode offers the lowest brightness, but without delivering the most accurate color, a combination that leaves little reason to use it.
