Dell 3008WFP.
Here are two additional test runs by setting ARGYLL_MIN_DISPLAY_UPDATE_DELAY_MS
in 50ms steps from 200 to 800. The following testset, interspersed with white
patches, has measuring errors only in -Iw case. The stabilisation point seems
to be around 700ms, that is how the colverify reference is measured:
ARGYLL_MIN_DISPLAY_UPDATE_DELAY_MS=700 and without drift compensation. Needless
to say I've run this and also different tests more than once with same results.
Something in the -Iw behaviour is causing this. Setting large delay is only
bandaid because without drift compensation the measured delay seems to work.
Test script:
--------------------------------------------------------------------
./test.sh test-Iw "$(seq -s " " 200 50 800)"
./test.sh test-noIw "$(seq -s " " 200 50 800)"
#! /bin/bash -Cue
for ms in ${2}
do
date="$(date +%Y-%m-%dT%H%M)step${ms}"
export ARGYLL_MIN_DISPLAY_UPDATE_DELAY_MS=${ms}
dispread -Yp -yl -v2 -c1 -Iw -X i1D3_Dell_3008WFP.ccss ${1}
#dispread -Yp -yl -v2 -c1 -X i1D3_Dell_3008WFP.ccss ${1}
mv ${1}.ti3 ${1}.${date}.ti3
colverify -v2 ${1}.ti3.ref ${1}.${date}.ti3 2>&1 |tee ${1}.${date}.txt
