Supported projectors and meters
ProjectorCal does not need a model-specific database. It measures, suggests a change, measures again and learns how many percent one menu step moves your projector. What a profile adds is the menu layout that cannot be learned: how many gamma points there are, and which meter timing to use for the automatic run.
Verified means full calibration runs on real hardware. Everything else is expected to work and is set up from the same assumptions. Please report your model (see Help us verify your model).
Projectors
| Model | Status | Gamma points (Control Point) | Notes |
|---|---|---|---|
| Vidda C3S | ✅ verified (7 full runs) | 20 × 5 % | Case study |
| Vidda C3 / C3 Pro / C3 Ultra | expected to work | 20 × 5 % (assumed) | Same VIDAA Expert menu family |
| Hisense / Vidda C2, C2 Pro, C2 Ultra, C2 Max | expected to work | 20 × 5 % (assumed) | Check the point count in your menu |
| Hisense / Vidda C1, C1S | expected to work | check | |
| Hisense PX1 / PX2 / PX3 (Pro) laser UST | expected to work | check | White Balance + Gamma Calibration in the Expert menu |
| Hisense Laser TV (L5, L9 …) | white balance + CMS | none (start with this) | 2-point and multi-point white balance |
| Any other projector or TV | white balance + CMS | 20, 10 or none | Needs Gain/Offset (or RGB high/low) white balance |
The models above run Hisense’s VIDAA system and share the same style of Expert picture menu: Color Temperature → White Balance (Gain / Offset R G B), Gamma → Adjust → Control Point (Gain), Color Tuner / CMS (Hue, Saturation, Brightness of 6–7 colors). Menu names differ slightly between models and firmware versions.
Choosing the gamma layout
Open Gamma → Adjust (or Gamma Calibration) in your projector menu and count the Control Points.
- 20 points → point k acts on the 5·k % gray step (point 10 = 50 %). This is the Vidda C3S layout.
- 10 points → point k acts on 10·k %.
- No points (only presets like 2.0 / 2.2 / 2.4 / BT.1886) → choose no luminance gamma points: the program then suggests which preset to use.
Not sure? Pick the closest layout and use Gamma by points → point probe: change one point by a few steps, do a check pass, and the program shows at which gray step that point’s effect peaks.
What else differs between models (and how the program copes)
| Quantity | On the C3S | On other models |
|---|---|---|
| Gain: effect per step | learned in the first run with a Gain change | the same |
| Offset: effect per step | coarse, ≈ 5 % at white, 25 % at 20 % gray | learned from a run with an Offset change |
| Gamma point: % per step | ≈ 2.3 % of its step’s luminance | learned from the first gamma round |
| CMS Bright / Saturation | ≈ 10–12 % / ≈ 2 % per step | learned from the first CMS change |
Until a step size is learned, the program limits the first change (e.g. at most 2 steps of Gain) so an unknown projector is never pushed far in the wrong direction.
Meters (colorimeters and spectrometers)
ProjectorCal talks to the meter through ArgyllCMS spotread, so
any instrument ArgyllCMS supports can be used. Pick the model in Settings → Meter model: it decides which
automatic video to play.
| Meter | Status | Auto-run video | Notes |
|---|---|---|---|
| Calibrite Display Plus HL | ✅ verified | standard | Run Calibrite PROFILER once so third-party software can use it |
| i1Display Pro, i1Display Pro Plus, Calibrite ColorChecker Display Pro / Plus | expected to work | standard | Same i1Display family; ≈ 1 s on white, up to ≈ 10 s on black |
| ColorMunki Display, i1Display Studio, Calibrite ColorChecker Display | expected to work | slow | Same sensor, firmware-limited to slower readings |
| Datacolor SpyderX / X2 / Spyder (2024) / Spyder5 / Spyder4 | expected to work | slow | Warm up 10–15 min; black calibration when asked. Spyder4/5: install calibration data once with ArgyllCMS oeminst |
| X-Rite i1Pro / i1Pro 2 / i1Pro 3, ColorMunki Photo / Design, i1Studio | expected to work | slow | Spectrometers: accurate color, noisy below ≈ 1 nit — the darkest patches may be flagged. White-tile calibration at start |
| Klein K10-A | expected to work | standard | Fast and very good in low light |
| DTP94, Huey, ColorHug / ColorHug2, Spyder2/3, JETI specbos / spectraval, HCFR | should work | slow | Older/slower devices: gray tracking and gamma are fine, absolute color is less certain |
The slow videos show every patch twice as long (SDR ≈ 27 min instead of 14, HDR10 ≈ 13 min instead of 6.5). If a meter is even slower than that, the program does not guess: the patches it could not read are flagged and left out of the analysis.
Accuracy on laser projectors
Laser light has very narrow spectral peaks. A colorimeter’s factory calibration was made for other displays, so its absolute white point and saturated colors can be off by a few hundred kelvin / a few ΔE on an RGB-laser projector. What stays reliable: gray-scale tracking, gamma, and every change between runs — which is what calibration is about. To get absolute accuracy as well:
- use a spectral correction (
.ccss) for RGB-laser displays, e.g. from the DisplayCAL colorimeter corrections database, and set it in Settings → Correction (-X), or install it into the meter and pick it under Display type (-y); - or, if you have access to a spectrometer (i1Pro family), create your own
.ccsswith ArgyllCMSccxxmakeand use it with your colorimeter.
Help us verify your model
Calibrated a model that is not marked as verified? Open an issue titled **“Verified:
- projector model and firmware version, meter model, ArgyllCMS version;
- the number of gamma Control Points in your menu and, if you ran it, the point-probe result;
- the exported JSON of your runs, or at least the run table from the Full check screen (γ, gray ΔE, color ΔE).
That is enough to mark the model as verified and to add its measured step sizes as starting values.
