if you watched our recent review of dell's ultra short throw laser projector
0:04
the s718 ql known affectionately around
0:08
the office as kylo ren then you already know that it's a badass 4k HDR projector
0:14
with insane brightness that works just about anywhere
0:18
but what you didn't know is that we actually have not one
0:22
not even two but three kylo ren's and today we're
0:28
gonna do something big with them
0:31
something big and wide
0:40
okay so first thing we need aside from projectors is a rig powerful enough to
0:45
run three 4k displays in games at once so
0:50
what we're using is three quadro p5000
0:54
gpus then we needed a platform that
0:57
could not only support all three of these quadros but that would also have
1:02
space for an additional expansion card
1:05
so we're using an x99 ews from ASUS a
1:09
core i7 6900k eight core processor with
1:13
a hundred and twenty eight gigs of g skill tridency RGB RAM because
1:18
why not and then because our goal isn't
1:21
to display the same image from three projectors no no we want to make one big
1:26
image we need an NVIDIA sync 2 expansion
1:30
card this is the same one from our 16k
1:33
gaming build which you can check out right over there
1:36
powering the whole thing we've got a platymax df platinum 1200 watt power
1:41
supply with sleeve cables right out of the box we've got an equal lens tempered
1:45
glass case although the glass is off right now so i can point at all this
1:49
stuff with high density soundproofing insulation in the front top and side
1:53
we're using a lick max 2 240 millimeter aio cooler that can handle up to a 350
1:59
watt processor and we're using lipa chopper advanced led fans all courtesy
2:05
of enermax who get a big shout out for sponsoring this video
2:09
so then we've got three projectors
2:13
we've got a pc to power them now's the big reveal
2:18
we are going on a little field trip outside where
2:23
we're going to be creating one gigantic
2:26
image on the side of our neighbor's
2:29
building hey i think i solved the network problem
2:35
uh we had a network cable running over to the laser cutter uh so i threw a
2:39
switch here i think for i think we're actually pretty close to the 100 meter
2:44
limit though for Ethernet on that subject
2:48
i think we've got every extension cord in the entire building
2:54
daisy chained together we got enough power out here because we're running
2:57
three 5 000 lumen projectors projectors it's
3:01
cold sorry projectors so yeah they're laser they're efficient
3:05
but still so there are a number of challenges that
3:10
we have to address before we're going to be able to game on this
3:14
number one is that all these projectors
3:17
need to be level off the ground so the innovative strategy that we've come up
3:22
with is a combination of these rocks
3:27
these rubber papers and then we got some printer paper to
3:31
kind of do the fine adjustments at the end problem number two that we have to solve
3:37
is that they all have to be exactly the same distance
3:41
away from the wall although what's cool is that they don't have to be the same
3:45
distance away from each other because the quadro sync card in our
3:50
configuration here allows us to fine tune NVIDIA's mosaic settings on a pixel
3:56
by pixel basis so that we can get them to butt up right against each other
4:01
problem number three is that each one of them has to be
4:05
keystone because we can make all the pixel by pixel
4:09
adjustments in the world that we want but ultimately
4:13
if you have some overlap at the top and a gap at the bottom the mouse movements
4:17
are going to be really unnatural problem number four
4:20
is that our office is right next to a train
4:23
obviously we couldn't do this inside because we wanted to project you know
4:28
like a freaking 80 inch diagonal screen that's been 80
4:32
foot 80 foot sorry imperial is not my strong point
4:36
okay i'm not quite sure how you intended these runs james one for beanbag maybe
4:40
one for beanbag do you want me to help you um help make a spot in it for you
4:45
okay
4:49
okay come on over here okay hold on let me put at least two or
4:54
three is it that heavy yeah it's pretty heavy oh okay okay so
5:00
we've got them good enough because we're not gonna stay
5:04
out here all night um now it's time to make some fine
5:08
adjustments so with monitors you use bezel correction to make it so that when
5:12
something passes over a bezel you don't end up with it misaligned like this
5:17
but now we want overlap i feel like i'm giving a presentation or something so
5:22
now we're just going to you know click the mouse over there you know it took a
5:26
lot of tweaking but once we got it working
5:31
it was absolutely freaking
5:35
sick like james you are actually
5:41
like 40 feet from the start menu right
5:44
here here you go bud guide me in
5:49
you're trying to try to get
5:57
one of the things we learned is that just because it's awesome
6:01
doesn't mean that it is actually usable
6:04
no there now there's trees in the way yeah we did not think this through
6:09
clearly some games operate better in 48 by nine aspect ratio than others do oh
6:15
then your weapons you lost like a couple hp on the jump oh look at the ammo i
6:19
have how much do i have
6:22
yeah that's quality is this resolution
6:25
maybe i don't know what any of these are can you see something that looks like
6:29
system so it turns out that just because you're using three 2500 graphics cards
6:35
that doesn't mean that you can actually game at 60fps
6:39
three times 4k is a lot of pixels you know how gta
6:44
tells you how much video memory you're gonna need for the settings you pick
6:48
it wanted 14 gigs so thanks for watching guys a huge shout
6:53
out to dell and enter max for allowing
6:56
us to uh come out here in the middle of the night
7:00
in the cold and have an utterly unique if not particularly um
7:06
advantageous gaming experience if you guys dislike this video you can hit that
7:10
button but if you liked it hit like get subscribed maybe consider checking out
7:14
