in this video we're going to review samsung's other premiere lsp90 4k laser projector which
provides almost full coverage of directionality color space surpassing even reference mastering
monitors keep watching hello everyone frieza field from hdtvtest here the most important
thing you need to know about the samsung lsp90 the premiere projector is that it is equipped
with a triple laser rgb light source as you can see from the spectral power distribution showing
almost monochromatic wavelengths of the red green and blue colors and this in turn actually provides
an extremely wide color gamma and rec 2020 coverage is 98 and this is the largest that we've
actually measured on a consumer display and if we turn to dsi p3 color camera coverage you can see
that it will cover 99 of dci p3 as well now the thing with such a white color gamut is actually
quite you know counter-intuitive in a sense because you know that will mean that the colors
are going to be slightly inaccurate because no current mastering monitor can achieve directivity
coverage yet and therefore when we look at a color checker sg chart where 140 patches were measured
you can see that we had difficulty trying to rein in the colors and make them adhere to not only rec
709 but also dci p3 in terms of the accuracy and therefore some of the colors will look overblown
oversaturated but i think you know if you don't have a reference monitor you may like this
slightly more vibrant and more vivid colors but i think you know if accuracy is your thing
it is very difficult to use this samsung premium projector as a benchmark despite that i think
you know the triple color laser does have its advantages in that you know because you are using
a triple laser without any color wheel without using any color filter to achieve this sort of
white color combat you can still get really bright and intensely colorful images and this is one of
the appeal of the samsung lsp 90 projector and i think hdr images they not only look bright they
also look really colorful as well and this combination gives a really strong hdr impact
that pops off the screen as much as i've actually seen from a consumer projector this ultra
structural laser projector is equipped with a 0.66 inch dlp chip from texas instruments that is quite
impressive in a sense that i think the contrast and the black levels are probably the deepest
that i've actually seen from any ultra structural projector but of course you know if you want to
benchmark it against jbc's front projectors then you know there is just no competition but those
are not ultra structural projectors and i think ultra structural projectors these days you know
try to fulfill a function of trying to replace the television and therefore you know they can
actually go very bright and because of the ultra short troll form factor you get not that much of
a light loss and therefore you can actually still get a pretty watchable picture in a
room with some ambient lighting next what we'll talk about would be the motion and i think that
the motion on this projector is going to be quite problematic for those of you who want accurate
24 frames per second reproduction because this projector is inherently 60hz centric and therefore
it can't reproduce 24p motion natively without some sort of telesconic judder and therefore you
are forced to use gender reduction on the samsung projector to try and smooth out the motion but
the moment you do that you will be introducing some frame interpolation and therefore you may
be incurring some interpolation artifacts and also some soap opera effect however mild and the other
thing with this projector is obviously it is sold in the uk when it is sold with a satellite
tuner and also a digital freeview tuner as well but because the projector is 60hz centric 50hz
broadcast will have to go through some sort of framerate conversion and therefore you may see
some stuttering until you again have to engage picture clarity or data reduction
to try and smooth them out and because this projector is not 120 hertz when it comes to
motion resolution is always going to be kept at the sample hole baseline of 300 lines regardless
of what you do to the picture clarity settings and i think that there are a few things that
i need to talk about in terms of the laser light source so the uniformity is very good you know by
any projectors are standard i think you know if you are seeing some sort of scan lines here
and there throughout this review video it is because of the refresh rate of the
projector and mismatch with my camera so those are actually not visible in person but another thing
about this laser projector is that in very bright scenes you may be able to see some very fine
speckled shimmer of almost like film grain but it is not film grain that is present in the content
itself it is actually introduced by the laser but i think you know it is not something that i would
be concerned of unless you are sitting quite close to the screen and another thing about
the triple laser implementation on this samsung premiere lsp90 projector is that it is prone to
slight chromatic aberration from the lens in that the pixels are not actually perfectly aligned in
terms of the red green and blue but i think from a normal viewing distance it is going to be not very
visible at least on my review sample this video is sponsored by box the online technology store

upscaling is very good i always like samsung's upscaling it is very forgiving you know it
retrieves nice detail without excessive ringing or fizziness and when it came to video based
interlacing again samsung's jackie suppression is one of the best if not the best in the business it
suppresses jagged ages in this bouncing bar test pattern from the hqv benchmark disk very nicely in
terms of film mode the interlacing this projector correctly detected three two cadence but it failed
to do cadence and even three two cadence in 1080i was a fail as well so i think you know if you are
sending an interlaced video signal to this projector you might want to reconsider and
ask your source device to do the interlacing so that you know you send a progressive signal to
this projector for the best picture quality i've touched very briefly earlier about hdr
and i really like the hdr presentation from this projector because of the combination of the quite
high brightness which is again not needing any color filter to achieve wider color gamma so you
get a combination of high brightness and really vibrant colors at the same time but i think
the tone mapping on this projector doesn't have the dynamic mapping on jvc's dila projectors
and so depending on the metadata of the film and what sort of level it is master
that you know you have to lower the contrast to retrieve a bit more specular highlight detail
in terms of 10 bit native gradation as with most samsung displays there will be some posterization
in smooth gradients for example in the spanning shot from the martian and also surrounding bright
elements there will be some posterization now this can be reduced by engaging color space native
which is necessary to achieve the widest color gamut 98 percent of relativity that this projector
is capable of anyway but just bear in mind that you know you are not getting accurate colors you
can also choose to switch to bt 2020 which will again reduce the posterization input lag in game
mode measured 55 milliseconds which is higher than most samsung tvs that we have measured and i think
this projector also supports auto low latency mode but i think most hardcore gamers probably
will be turning to other displays for playing reflex-based games with this out of the way let's
talk about the designer projector the projector is only available in a white finish which fortunately
doesn't show up that many fingerprints but i think you know the reason why samsung and many
other ultra short show laser projectors have gone with a white finish is because they are meant to
be used in a brighter environment and the front of the projector has the speakers which is covered in
cavadra acoustically transparent cloth and the connections are found on the rear of the unit
and there are three hdmi 2.0b ports one of which is the er port and there is also a wide remote
control supplied with a projector with very few buttons but i think you know it is very usable and
just feels quite good to hold in the hand and i think one thing to mention is that you know
there are obviously side vents on the projector but this projector is very very quiet you know
by the standards of any projector and there is no coil wine whatsoever and i think that the
triple laser engine certainly helps with not having a color wheel and therefore this projector
i feel extremely comfortable using it you know even with low volumes from the projector the
background noise certainly won't spoil your viewing experience now of course you know if
you engage high altitude mode on the projector then the fan noise will go up so unless you
know you're staying in a really high place i don't think you should engage high altitude mode anyway
and within the menu itself you know electronic focus is provided which is fantastic and
as with most ultra structural laser projectors there is no zoom control so you have to physically
place a projector close to the screen to enlarge the projected image but there are some screen
adjustments provided by samsung where you can adjust four points or more precise 15 points but
i think you know when it comes to the sort of geometric correction i feel that it will
always degrade the image however slightly so i try to keep them to a minimum and i think when
it came to the menu system it feels very much like a samsung television and that is a good
thing because i think the collection of smart tv apps that have been provided on this projector
is very comprehensive you get netflix you get amazon prime video bbc iplayer disney plus apple
tv youtube the lot really and obviously the smart hub is very accessible and easy to use as well
last but not least let's talk about the sound and i think most people who buy the sort of projector
may have their own home theater solution which will provide beefier sound but i was generally
quite impressed with the sound output from this projector i think you know it is certainly one
of the best in projector sound that i've heard from any projector period and i think you know
many of you will be satisfied with it unless you go one step up to a home theater solution to sum
up samsung's the premier lsp 90 laser projector is probably the best ultra structural laser projector
on the market today that i've actually tested i mean it it's not without its shortcomings i think
the color accuracy leaves a lot to be desired and i think that you know its motion is hampered by
the 60 hertz centric design of the dlp chipset but when you consider the supremely white color gamut
that this projector is capable of you know the bright and punchy hdr images the quiet operation
and i would say class leading sound quality it earns our recommended award to watch more of our
