Optoma HD25-LV Projector Calibration and Settings

Optoma HD25-LV Projector Calibration and Settings

We calibrate virtually all over $1000 home projectors that we review.  The Optoma HD25-LV received the usual treatment. This time, Mike got to calibrate it before I really started watching the HD25-LV. Since Reference and User seem identical. I could compare Mike’s finished calibration results with the out of the box default by comparing User (post adjustment), to Reference. Our calibrations, including the Optoma HD25-LV, include a grayscale calibration (adjusting the balance of Red, Green, and Blue), along with brightness, contrast, color saturation, tint (where applicable), etc. We recently, additionally do a full CMS calibration of individual colors which will be available to our subscribers (starting August).

Let’s take a look at the numbers:

Optoma HD25-LV Color Temperature

Before we provide our settings, let’s see what we started out with: Pre calibration, these are the color temperatures over the grayscale range (repeated from the Performance page):

Color Temp over IRE Range (Bright mode)

30 IRE 7033
50 IRE 6889
80 IRE 6733
100 IRE 6673



Optoma HD25-LV Basic Settings

Below (also repeated) shows the default brightness of each mode, and the color temperature of white (100 IRE) that we measured.

Lumen Output and Color Temp at 100 IRE (mid zoom)

Cinema 1734 @ 6755
Bright 1794 @ 6667
Photo 1770 @ 7792
Reference 1378 @ 6578
User equals whichever mode you started from

In addition to calibrating Red Green and Blue for a correct grayscale balance (6500K), there are a number of other settings that come into play. Typically Contrast and Brightness (white balance and black balance), need to be done first. Color saturation and gamma also need adjustment.

Settings for measurements (default values are in parenthesis)

Cinema Bright Photo Reference User
Contrast (-3) (-2) (-4) (-4) (0)-3
Brightness (0) (0) (0) (0) (0)
Color (10) (17) (7) (4) (0)-4
Tint (50) (50) (50) (50) (50)
Color Temp (Warm) (Medium) (Medium) (Warm)
Gamma (Film) (Video) (Graphics) (Standard)

Lamp Mode= Bright (unless noted otherwise)
All other settings are default

Dynamic Black is OFF for Bright and Reference Modes.

Brilliant Color is On, and set to 10 (max) for all but Reference which is 7, and that explains why Reference measures significantly lower.

Optoma HD25-LV Post Calibration Grayscale: User Mode

Color Temp over IRE Range (Post calibration)
20 IRE 6546
30 IRE 6524
40 IRE 6581
50 IRE 6582
60 IRE 6593
70 IRE 6543
80 IRE 6514
90 IRE 6574
100 IRE 6485
Average gamma         2.19

Excellent results in User our “best” mode, also very good in Cinema – our “brightest” mode selection!  Numbers are degrees Kelvin.

    Thabk you for this extensive review!
    I subscribed to get the full calibration specs. But I cannot seem to find the brilliant colour settings used after calibration. Same for gamma and colour temp.

    With kind regards,

      Hi Zoldar! The full Advanced Calibration Info for subscribers is available here (https://www.projectorreviews.com/optoma/optoma-hd25-lv-projector-advanced-calibration-information/) in case you missed it. But here are a few words from our calibrator Mike that you hopefully will find useful:

      “For the calibrated User mode, Bright mode was used but with gamma on Film. Brilliant Color is 10 and a Warm color temp are default. The Optoma projector has a single, full range, grayscale control under “Color Settings”. In that menu, you have the RGBCMY color management and then White, which is the RGB grayscale.”

        What about Noise Reduction and DynamicBlack?

        • ProjectorReviews.com

          Hi Jason,

          I don’t get into noise reduction. I
          normally watch at the default settings for review unless there’s a
          problem. I used to favor minimal extra image processing (that includes
          noise reduction), but as all types of image processing is getting
          smarter, etc. Everyone’s using more and more, with the idea of trying to
          get an image that more closely resembles the original, rather than is
          the least changed from the source material.

          clarify that, here’s an example. A simple sharpness control mostly
          adds contrast to the image around edges to seem sharper, but with that
          are lots of artifacts. Now smart detail/sharpness enhancement uses a
          variety of tricks, but most importantly it analyzes the material to
          figure out what has been sacrificed, thus a control might recognize a
          face and sharpen it differently than other objects. Same would be the
          case with some noise filtering. I leave that one to your preferences.
          Generally “don’t get too carried away.”

          other question is Dynamic Black. My issue with the Optoma HD25-LV’s
          dynamic black, as I recall, is that it is not smooth at times. it
          almost flickers – or rather sometime’s brightens or darkens the overall
          image in steps, that are noticeable, often a second or two after a scene
          change. That bothers me. My wife doesn’t seem to notice. I normally
          will not use Dynamic black on Optoma projectors. Those small jumps
          annoy me. If they don’t bother you, turn it on… -art

            Thanks for the clarification. What you have said makes sense.

        • MikeR

          As far as the calibration is concerned, Dynamic Black was on its default setting of High. Noise Reduction is not a factor, so it’s set to whatever the default is for that mode.
