About the Optoma HD28HDR

Emily S.

A great picture with the lights on or off

A dark, dedicated home theater room isn't an option for many of us. Thankfully there are projectors like this Optoma HD28HDR that get bright enough to compensate for well-lit rooms. It also offers full HD 1080p resolution, accepts 4K video signals, and supports HDR (High Dynamic Range) for lifelike color and detail on screens up to 300 inches.

Gaming on a massive scale

I love playing couch co-op games with my husband, but our 55-inch TV just feels so small with a split screen. This projector is a great option for gamers who want to upsize their play area. Its 120Hz refresh rate and lightning fast 8.4ms input response time is great for fast-paced console or PC gaming. It also has a dedicated game mode that optimizes settings for better shadow detail — so you can actually see what's at the end of that dark hallway. 

Simple setup

The HD28HDR sets up easily on a table, or you can pick up a bracket and ceiling-mount it. The projector's built-in speaker helps facilitate a quick setup. But if you want a little more, use the minijack audio output to connect to headphones or a pair of powered speakers. Two HDMI inputs make it easy to connect your high-definition sources.

For the best picture quality from any projector, we recommend using a projector screen.

    Product Research


    DLP Projector: The Optoma HD28HDR projector incorporates DLP technology from Texas Instruments (TI), which creates razor sharp pictures and amazing videos with incredible colors and brightness, while also providing reliability and longevity. It can be used with 30" to 300" screen sizes.

    • DLP is a reflective technology and can deliver images with both high native ANSI contrast (50,000:1) and exceptional brightness (3600 lumens), creating a picture that is natural and life-like.
    • Video and graphics produced by the latest DLP technology are sharper because the mirrors on the DLP chip are so close together that the gaps between pixels in an image are less noticeable. Spaced less than one micron apart, its mirrors create a crisp, detailed image.
    • The inherent speed of DLP technology means that Optoma projector can output video and images at an astonishing rate of 120Hz for clear, seamless motion.

    240W Lamp: The Optoma DLP projector utilizes a user-replaceable 240W lamp for high brightness and long-lasting life. The 240W lamp delivers high brightness (3600 lumens) for a vibrant image in well-lit environments (with no direct sunlight or lights directed on the screen). It has a lamp life of 15,000 hours (ECO) / 10,000 hours (Dynamic), or 4,000 hours (Bright). You can order a replacement lamp from Optoma by entering the serial number of your projector here.

    Projection Lens: The Optoma HD28HDR features a F2.1-F2.31 projection lens with a focal length of 15.99mm to 17.14mm. The projection lens offers an optical (1:1x) and digital (0.8-2.0x) zoom with a manual zoom lever and focus ring to make sure your projected image looks great on screen. To adjust the image size, turn the zoom lever clockwise or counterclockwise to increase or decrease the projected image size. To adjust the focus, turn the focus ring clockwise or counterclockwise until the image is sharp and detailed. The projector will focus at a distance of 3.3' to 32.15'.

    • Image Shift: Image Shift electronically adjusts the projected image position horizontally or vertically (this is not true Lens Shift where the actual lens moves).
    • Keystone Correction: Keystone Correction adjusts the image distortion caused by tilting the projector. It has a manual vertical keystone correction of +/- 40 degrees.

    1080p Native Resolution: 1080p resolution gives you sharp and detailed images from HD content without downscaling or compression; perfect for watching Blu-ray movies, HD broadcasting and playing video games. Most movies are shot at 24 frames per second (fps). To preserve the purity of the original image, The Optoma DLP projector can accept high definition sources at 24 fps to display movies exactly as the director intended.

    • BrilliantColor: The Optoma HD28HDR DLP projector lets you watch your movies, TV shows, and play games with vivid colors. Its capable of reproducing the Rec.709 color gamut (over 1.07 billion colors), the international HDTV standard to guarantee accurate reproduction of cinematic color exactly as the director intended. BrilliantColor technology utilizes a new color-processing algorithm and enhancements to enable higher brightness while providing true, more vibrant colors in picture.
    • Dynamic Black Technology: Dynamic Black Technology gives more depth to your image by smoothly adjusting the lamp output, based on the brightness information of each frame. As a result, the Optoma HD28HDR DLP projector can create a stunning high contrast ratio of 50,000:1. Bright scenes appear crisp and clear, while dark scenes remain detailed with deep blacks and exceptional light and shade detail.

    Dual HDMI Inputs: With dual HDMI inputs (one HDMI 2.0 and one HDMI 1.4a), you can connect your game console, set-top box, laptop, PC, Blu-ray player or media streamer to the Optoma HD28HDR DLP projector. You can even turn it into a smart projector by connecting an HDMI dongle like the Google Chromecast, Amazon Fire TV, Apple TV, or Roku stick (sold separately).

There is also a 3.5mm audio output for connecting a soundbar or powered speakers. There is no stereo RCA output or digital audio output. The projector does not support ARC or eARC.

    USB Power Port: Use the projector's USB-A port (5V/1.5A) to power an HDMI dongle, such as Google Chromecast or Roku Stick (sold separately).

    Simple Control: The Optoma HD28HDR projector offers top-panel controls, comes with an IR remote, and supports HDMI-CEC.

    • Top-Panel: Top-panel controls included Power, Menu, Source, Information, Re-Sync, 4 Directional Select Keys, and Keystone Correction. Also on the top-panel are 3 LEDs that indicate On/Standby, Lamp, and Temperature.
    • IR Remote: The included IR remote provides wireless operation of the Optoma HD28HDR DLP projector. The IR (infrared) control sensor is located on top of the projector. Make sure to hold the remote control at an angle within 30 degrees perpendicular to the projector's top IR remote control sensor to function correctly. The distance between the remote control and the sensor should be no longer than 20'.
    • HDMI-CEC: HDMI-CEC (Consumer Electronic Control) enables synchronization of Power On/Off between the HD28HDR and connected HDMI-CEC compatible sources.

    Mounting Options: The Optoma DLP projector is designed to be installed in one of 4 possible positions. It can be tabletop or ceiling mounted in front of or behind your projection screen (ceiling mounting bracket sold separately). The projector should be placed flat on a surface and 90-degrees (perpendicular) to the screen. The projector is equipped with three adjustable feet for adjusting the image height when installing the projector on a tabletop. There are three M4 threaded inserts on the bottom of the projector to attach a ceiling mount bracket (sold separately).

    • The tilt angle of the projector should not exceed 15 degrees, nor should the projector be installed in any way other than the tabletop and ceiling mount, otherwise lamp life could decrease dramatically, and may lead to other unpredictable damages.
    • Allow at least 11.8125" on both the left and right sides of the projector, as well as allow at least 3.9375" above and behind the projector for proper ventilation.

    Note: Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your audio/video equipment.

    Projection Distance: The further away the projector is placed from the screen the projected image size increases and vertical offset also increases proportionally. See chart below for recommended projector distance based on size of screen; or use the Optoma Projection Calculator to assist you with placement of the projector.

    Screen Size Throw Distance
    30" 39.3"
    60" 78.7" to 86.6"

    Customer Q&A

    3 questions already asked

    Can the projector be setup to start on a specific input, or would the input have to be selected each time it's turned on?
    becky  Sep 14, 2022
    1 answer
    Per the Optoma manual Becky it does look like when you initially power up the unit, you then power up your source and the HD28HDR will detect the source and select that source to display automatically. It appears that IF you have more than one source connected and playing, you will have to manually select which source via the remote. These Optoma really slam for the price, a really great projector! I hope this helps.

    It can be hung upside down when ceiling mounted and definitely can work to create a limited amount of screen sizes when 14 feet away from the screen. We have advisors that can be reached by calling 1-800-324-9695 who can check if this will work for the image size you seek

    Get a ladder, light up the projector and find your optimal distance. Then set your mount at that spot. Use the keystone adjustment to fix the picture.
