If'the'Matrox'TripleHead'wigs'out,'when'QLab'loads'you'will'see'a'red'‘X’'next'to'the'video'file,'this'is'
showing'you'that'it'has'become'‘unpatched’'as'it'can’t'find'the'right'output.'So'we'will'need'to'first'
check'the'Matrox'TripleHead'setup.'So'quit'QLab'first'(for%non'Mac%users,%you%can’t%just%click%the%red%
dot%in%the%top%left%of%the%window%like%a%Windows%machine,%you%have%to%close%the%application%completely,%
so%with%QLab%visible,%go%to%the%menu%bar%and%go%QLab%–%Quit%QLab%or%press%Command%+%Q)%

'
Click'on'the'Matrox'“M”'icon'and'go'to'Quick'Setup'
'
'
'
'
'
'
'
'
'
'
'
'
'
Go'to'Use'a'selected'display'setting'and'select'
3'*'1280x800'60'Hz'and'press'apply.'The'screen'will'
flicker'a'few'times'over'about'10'seconds'and'then'a'
confirmation'screen'should'appear.'Press'‘confirm’'
'
'
You'should'then'be'able'to'launch'the'QLab'project'
BRIDGE'PROJECT'USE'THIS'
'
'
'
If'it'is'still'showing'a'red'X'next'to'the'
video'or'is'playing'on'the'monitor'
instead'of'the'projectors'we'will'need'
to'check'the'‘patching’'so'go'to'
Window'–'Workspace'Preferences'or'
press'Command'+','(that’s'a'comma)'
then'go'down'to'Video.'You'should'see'
two'entries,'one'for'the'LCD'display'
(L2240pwD)'and'one'for'the'output'to'
the'projectors,'which'will'either'be'
named'“Display”'or'
“MatroxTripleHead2Go”'and'should'
show'you'the'resolution'as'3840x800'
(if'it'shows'any'other'resolution'we'
need'to'check'that'Matrox'setup'again'
following'the'instructions'at'the'top'of'
this'document)'
'
As'long'as'we'see'those'two'entries,'we’re'good'to'go.'So'down'on'the'bottom'left'you'can'hit'“done”'
to'return'to'the'main'QLab'window.'
Click'the'video'track'and'then'go'down'the'
bottom'to'“Display'&'Geometry”'
'
The'video'surface'should'be'set'to'whatever'
the'‘other’'surface'was'we'saw'before'in'the'
patching'window.'So'this'will'be'“Display”'
or'“MatroxTripleHead2Go”'–'if'it’s'set'to'
L2240pwD'the'video'will'play'on'the'LCD'
monitor'instead'(we'don’t'want'that)'also'
make'sure'under'Mode'it'says'“Full'Screen”'
(this'is'the'default'anyway)'
'
There'should'now'no'longer'be'a'red'“X”'
next'to'the'video'and'it'should'then'play'
correctly'(hit'GO)'
'
If'for'some'reason'it’s'still'not'looking'right,'we'can'try'a'fresh'QLab'project.'So'quit'QLab'and'launch'
a'new'project'by'opening'the'QLab'application'icon'on'the'desktop.'When'QLab'launches'fresh'it'
should'auto'patch'all'outputs'it'finds.'So'drag'in'the'video'file'(named'something'like'
BridgeSwimmer_H264'with'a'little'green'dot'next'
to'it)'from'the'desktop'into'the'QLab'window.'It'
should'auto'patch'to'the'projectors'but'you'can'
check'this'with'that'“Display'&'Geometry”'tab'like'
we'used'before.'
'
You’ll'need'to'jump'over'to'“Time'&'Loops”'and'
enable'Infinite'Looping'if'you’ve'started'up'a'new'
project.''
You'can'probably'then'save'this'over'the'top'of'the'
old'project'so'that'next'time'you'load'it'it’ll'load'
these'‘last'known'good'settings’'
