Immersive True 4K UHD Gaming Experience


What is True 4K UHD

The Consumer Technology Association (CTA)® definition of 4K Ultra HD resolution states the display resolution must have at least 8 million active pixels.


Optoma True 4K UHD

Optoma UHD35+ True 4K UHD projector is powered by a revolutionary Texas Instruments 4K UHD DLP Chipset featuring a high performance DMD utilizing XPR video processing technology with fast switching to display 8.3 million pixels (4x the number of pixels of 1080P) as mandated by the Consumer Technology Association’s 4K UHD specification.

Image Comparison

Optoma’s True 4K UHD projectors deliver accurate, razor sharp, high quality images by leveraging its DLP 4K UHD chip and XPR technology.

True Colours Tell The Realistic Stories

UHD35+ incorporates RGBWRGBW 8 segment colour wheel to achieve vivid and stunning colour performance with 4,000 high lumens of brightness. Optoma’s specialised colour calibration and adjusting technologies exceeds HDTV Rec. 709 standards to present the truest and the most accurate colours, for authentic, and in-depth storytelling images. This is a 4K HDR high resolution home theatre that you will not want to miss out on!

DLP®️ BrilliantColour™ Technology

For UHP lamps, this technology is able to achieve up to 50% improvement in brightness over traditional three colour solutions. BrilliantColour technology offers up to six-colour processing enabling a wide colour gamut and making it possible to produce over one billion colours.


Optoma HDR HDR10 / HLG

UHD35+ supports HDR10 and HLG. When a HDR/HLG signal is imported, the projector automatically switches to HDR / HLG display mode. Through Optoma’s HDR colour mapping and tone mapping technology, it enables HDR / HLG movies or games to be presented with optimised performance in the accurate colour and dynamic contrast.


HDR / HLG Picture Mode

HDR, High Dynamic Range, is a standard that comes with a higher dynamic range in video signals, allowing the image to be shown with more brightness and colour without losing any details. UHD35+ allows users to adjust the dynamic range according to the video content or environment.

Enjoy HLG TV Programs from Youtube, BBC, and NHK

Hybrid Log-Gamma (HLG) is an HDR system that was specifically developed for television by the BBC and Japanese broadcaster NHK. Online video streaming platforms such as Youtube, Freeview Play, or DirecTV all support HLG formats as well. You can enjoy TV programs like World Cup games or Blue Planet at home with stunning HDR effect.

Enrich Your 4K Entertainment

UHD35+ supports two HDMI 2.0 for any external 4K devices e.g., Apple TV 4K, PS4 Pro, and XBOX One X.

The Smart and Simple Way to Watch Movies

Watching movies is easy. With the touch of a button, switch to “Cinema” display mode, and the image performs true to life with high contrast by the specific Gamma curve and colour gamut. In the meantime, it activates Brilliant Pulse on Red function to make the light pulse project onto the red segment of the colour wheel. Red enhancement reproduces closer to natural skin tones, better colour saturation and a more enjoyable viewing experience.

Dynamic Black

Dynamic Black can accurately control light bulb output power and automatically adjust it based on different image brightness. There is no need to use an aperture ring to adjust for dark scenes. With Auto Gain function, details are more pronounced and an increase in contrast ratio of nearly three times is achieved. This means that images appear true to life with dramatic increase in contrast.

Display on 60” TV vs. Display on 120” Projector

With the 60″ TV, even though the images are displayed in 4K, it is still hard to read the details due to the small size of the TV screen.

With the large 120″ projector image, everything easy to read.

[ Game ] Display Mode…Something Hidden in the Dark

Shadow Boost. All-day simulations

In Optoma’s Colour Lab, simulations were carried out for gaming in different ambient light settings to calibrate and boost the details in the dark and develop the exclusive “Game” display mode. This means that gamers can avoid getting stuck at a certain level, as they can clearly find the gimmick hidden in the dark.

HDR Effect

If game content supports HDR format, UHD35+ automatically switches to “HDR” display mode for optimal HDR images. If not, UHD35+ provides “HDR Sim” display mode to achieve HDR-effect images for the richest colour gamut and sharpest contrast, without sacrificing any detail.


Lightning-fast 240Hz Refresh Rate

The refresh rate is the number of times your display device updates with new images in each second. 240Hz means 240 times per second. The higher the refresh rate, the more frames your monitor can display in each second and the smoother your on-screen image can be shown.
Turning on the “Enhanced Gaming” mode in UHD35+, the image output will run in 1080P with 240Hz refresh rate, which is 4 times higher than standard PC gaming monitor.

UHD35+ 240Hz Refresh Rate =


4 times device updates per second faster than 60Hz

Note: Enhanced gaming mode supports any input source with different resolutions at any Hertz, and the output source runs in 1080P with 240Hz refresh rate.

Standard PC gaming monitor 60Hz =


Comfort and Ultra Smoothness

A low refresh rate would actually result in the display visibly flickering as it updated. This causes gamers to feel dizzy or uncomfortable. From the testing results, the difference is noticeable even when a character just walks around in the game.
UHD35+ is the lightning-fast projector with 240 Hz refresh rate, producing great picture quality for fast gaming action with virtually no motion blur. It is just perfect for gamers playing games for many hours.

Focus and Win

With its 240Hz refresh rate, the UHD35+ reproduces video motion with the ultimate smoothness and clarity. You will never miss your target. Just focus and win the games.

Lag-Free Gaming 4.2ms Input Lag

For party games or PC gamers, UHD35+ is the first choice in Optoma True 4K UHD projectors. It incorporates “Enhanced Gaming” mode with super low input lag. Gamers enjoy low-latency between the operation of controls and win the game in milliseconds.

Keep Eyes Safe And Comfortable

Projector screens actually are better for your eyes. Projectors are able to produce much larger images, which put less strain on your eyes. In addition to this, projected images are reflected light while TVs are direct light which gives more eye strain.

3D Worlds Behind The Walls

Auto Display Mode for 3D

Optoma provides “3D” display mode to resolve the issues related to variations in brightness of 3D images due to overlapping signals and use of specialised lenses. When a 3D signal is received, the system directly switches to [3D] mode to elevate image brightness and contrast.

ISF Display Mode

This feature allows you to save your calibrated day, night and 3D mode settings for the ideal viewing experience.

Project onto any wall

Six colour compensations are provided to suit different types of wall spaces in the home and avoid distortion of colours. Even in the absence of a projector screen, images can be viewed on a wall space with the most accurate colour gamut.
