Runco LS-5 Projector Calibration and Settings

Posted on July 17, 2013 by Art Feierman
Mike performed his usual measurements and calibration on the Runco LS-5:

Runco LS-5 Color Temperature

Lumen Output and Color Temp at 100 IRE for Various Color Temp Settings
5500 554 @ 5276
6500 613 @ 6082
7500 662 @ 6928
9300 597 @ 8278
Native 650 @ 6432

There are no pre-set modes, but there is an adjustable color temp control. We measured white (100 IRE), at each color temp setting:

Color Temp over IRE Range, 6500 and Native Color Temps
6500 Native
30 IRE 6038 6427
50 IRE 6068 6429
80 IRE 6054 6434
100 IRE 6082 6432

A quick look from dark gray to white for the 6500K setting reveals this:

Color Temp over IRE Range, 6500 and Native Color Temps:

Settings for measurements (default values are in parenthesis):

Contrast (0)= -1
Brightness (0)= 3
Color (0)
Color Temp (6500)

All other settings at default (untouched)
Measurements taken at mid-zoom and with lamp in Standard (High) mode

Note, with the LS-7, I wrote this about the adaptive contrast.

If you turn on Adaptive contrast, there goes your Contrast setting 103, with Adaptive on, is crushing everything even close to whites, on a 255 scale, probably everything over 210 is going pure white. On one scene from Quantum of Solace (speed boats, and big white wave spray), I had to drop contrast to below 72 to preserve the near whites, when Adaptive was selected. Be warned!

I managed to get through my entire visit with the LS-5 without turning it on. It wasn't missed, but for some extra punch, that can get over the top, try it out.

LS-5 Color Temp over IRE Range (Post calibration)
20 IRE 6403
30 IRE 6496
40 IRE 6494
50 IRE 6548
60 IRE 6519
70 IRE 6524
80 IRE 6492
90 IRE 6540
100 IRE 6422

Average gamma = 2.18

LS-5 Color Temp over IRE Range (Post calibration):

Output: 648 lumens

That's an exceptionally tight range from 20 to white, of only 15K and averaging just below a perfect 6500K.
