Most modes have vibrant colors, but they are oversaturated

Calibration is difficult to achieve exactly

In comparison to its competitors, this DLP does not offer great sequential on/off contrast.

A bright spot in the lower middle section of the screen may be caused by chromatic aberration from the lens (red, green & blue alignment). (Optimal installation can minimize this effect)

Compared to similar models, it is more expensive

It is too difficult to access needed features with the remote because it is too minimalistic

Sense of aesthetics

Lifestyle Design

A perfect blend of minimalist design and superior engineering, The Premiere is beautiful from every angle. The housing of this UST projector is only available in white, as is the current trend with many of these units. Several manufacturers, such as Samsung, opt for white housings because it gives the product a more modern appearance. The credenza would look better if the housing was black to match the other components.

Front speakers are covered in attractive fabric with rounded corners. In accordance with most home theater USTs, the lens of this projector is recessed under the top. Two adjustable feet are located at the front of the projector, so you can fine tune alignment with your screen physically.

Installation, throw ratio, zoom

Ratio of throws to hits: 0.189:1

Unlike just about any other projector, the Samsung LSP9T can sit close to the screen. A 100″ screen can be made by placing the projector 4.4 inches away from the screen and a 120″ screen can be made by placing it 7.7 inches away.

Projector to Screen Alignment

Overall, we found it more difficult to align the laser TV and projector than other laser TVs. Due to its smaller adjustable feet, the Samsung LSP9T does not have as many as the Hisense L9G. As a result, fine tuning the alignment was a little more challenging.

In addition, when you adjusted the height of the feet you had to realign the projector every time, since you could not adjust the feet without lifting the projector.

Aligning the screen and projector was easier with the screen alignment menu option, though.

Projector Focusing

In the LSP9T, the focus mechanism can be adjusted electronically based on the size of your screen between 100-130″. Samsung gives you a focus screen, but we are not crazy about it.

Projector to Screen Alignment

The focus is only optimized for the screen size it’s designed to throw onto; some USTs do not have this feature.

Lens Zoom

To enlarge or decrease the size of the image, USTs use manual movement of the projector forward or backward.

Geometric Correction/Warping/H & V Keystone

A geometric correction option is available on the LSP9T. Alternatively, you can choose the more advanced 15 point correction for granular control of correction points across various sections of the screen. There is a 4-point correction which adjusts the corners of the screen, or you can choose the 10-point correction which adjusts the corners of the screen.

Keystone is not present in UST projectors, either horizontally or vertically. Adjusting the feet of the projector on the screen surface and realigning the projection placement is the only way to fix distortions.

Projector Light Source

Its lifetime varies depending on the laser power and operation modes it uses. The LSP9T has a 20,000+ hour life to half brightness.  As an RGB Tri-Laser projector, Samsung Premiere LSP9T UST is equipped with laser diodes for Red, Green, and Blue light. A screen with more colors than BT.2020 (*107%) can be achieved with this technology.  Projectors used in sports events have laser or LED as the light source.

Similar to its sister model, the LSP7T, this UST projector is powered by the same chassis.  In contrast to blue laser phosphors, which are inferior colors and phosphor wheels that cause color to appear dull.  The color of the image is much more lifelike when created with RGB laser diodes.  which create colors that are much closer to reality than anything we have ever experienced in our homes, or even in theaters!


An environment in a living room with ambient light coming from light fixtures and windows would look like:

There is plenty of power and oomph in the LSP9T for it to compete with the brightest ambient lighting conditions. The image was well discernible and watchable both on an ALR screen and on a transparent acoustical screen. In this scenario, it is obvious that the UST ALR screen would be the best option. Such bright projectors are good for day time use.

Spectra Projection Vantage UST screen was used for the testing.

When the lights are off, and the environment is devoted to light control:

In the absence of light and with ambient light controlling the image, the colors and depth of the image take on a whole new meaning. This UST has triple laser light sources and stunning BT.2020 colors, making it one of the best on the market!

My first impression of the LSP9T, and even subsequent viewings, were jaw-dropping when compared to other projection technologies I have used over the years. Helmholtz-Kohlrausch (HK) effects increase perceived brightness because of added color volume. It also enhances the already superb inter-image contrast to some extent, which results in an image that is rich, sharp, and detailed in three dimensions. When installing the LSP9T in a light-controlled environment, you should go with the standard white screen.

Color Gamuts

As content utilizing that wide color gamut becomes more available, this UST projector will keep you future-proofed. It covers 147% of the DCI-P3 color spectrum, and 106% of BT.2020. With HDR10+ certification, this is the first high dynamic range projector to provide superior image quality.

Only the green color was slightly elevated at the highest 100% point on the LSP9T, which achieved the Rec.709 color gamut easily. The BT.2020 levels are set by default in all modes except Movie and Filmmaker, so the image appears oversaturated and cartoony. The best way to tame this oversaturation is to begin with Movie or Filmmaker as a baseline.

In terms of color gamut, HDR and SDR are similar out of the box. There is a bit of oversaturation and a phase difference. The wider bandwidth and closer approach to BT.2020 don’t pose as much of a problem as SDR. In spite of this, Red, Magenta, and Green were all out of phase before calibration, leaning too much toward one another. There was an imbalance between white and blue. In real life images, this is hard to see in the saturation sweeps (points between D65 White and 100%), but it is an issue in some newer RGB Laser USTs.


In terms of dynamic contrast ratio, this laser TV boasts a 2,000,000:1 ratio, which is a far more superior contrast ratio than the lower priced alternatives.


In displays, sharpness is typically enhanced with rudimentary edge enhancement processing, which, if handled incorrectly, can result in severe edge outlining, especially on straight lines and object outlines. In the following examples, you can see examples of “ringing” or “haloing”.

A few manufacturers and displays are capable of making images appear sharper and more detailed without distortion by improving sharpness. DarbeeVision is a good example of doing it right. If used judiciously, it can create images that appear more detailed, more 3-dimensional, and have more contrast without leaving white lines surrounding objects. It’s more than that with Sony’s Reality Creation.

Motion Handling

LSP9T has quite good motion, despite converting 24p (23.975Hz) into 60p (59.94Hz) when it receives 24p. There may be times when the display fails to handle motion properly, causing “The Soap Opera Effect” (SOE). The situation here is different. To avoid jitter and poor motion, Samsung ought to be capable of doubling or tripling the rate evenly to 48 or 72Hz from film sources using its good telecine processing.

Imaging Technology/Chipset

Using Texas Instruments’ 0.67″ DMD chip with 2716 x 1528 pixels, the LSP9T uses XPR technology to diagonally shift the image 12 pixels vertically and 12 pixels horizontally.

In UHD at 3840 x 2160 resolution, it goes from 4 million pixels to 8 million pixels that are individually addressed and perceived at 120Hz. There are some who argue that this isn’t a true native 4K UHD resolution.  Nevertheless, the difference between native 4K displays and the resultant image is almost indiscernible. When it comes to real-world perceived image detail, 1 pixel test patterns are the only true indicator, but this is essentially moot in real life.

It is claimed that the larger chip size and smaller pixel pitch of this chip will enable higher perceived resolution, as well as better native contrast over its smaller 0.47” 1920 x 1080 competitor.

Gaming input Lag

Despite my lack of interest in gaming, the LSP9T is equipped with a Game mode, which is aimed at providing dedicated low-latency based processing for those of you who are gamers, which I am not. There is no doubt that the input lag on this device can still be considered to be high even in Game mode if you are a video gamer. Here is our list of other suitable projectors for gaming.

It is around 55ms in this mode. Casual gamers won’t have a problem with this. Most people who play first-person shooters for fun and to pass the time shouldn’t have a problem with it, but for professionals who compete in first-person shooters, the game is far too unresponsive to be competitive. In terms of game mode, it works well for most users thanks to the excellent motion handling that I mentioned earlier.

Built-In Sound System

Acoustic Beam Audio System is built into the LSP9T, with 4.2 channels and 40W output power. ATMOS cannot be achieved without speakers above and around you, but this system does surprisingly well at simulating ATMOS. This movie works well if you are seated in the center sweet spot because there are phantom sounds coming from all around you and an engaging dialogue in the center. This is a feature that makes it a portable projector for outdoor.

On the top front left and right sides, there are twenty-two small tuned ports, along with two tweeters and a mid-woofer. You get the ATMOS Surround effect mentioned earlier, which creates a convincing soundstage for a projector by sending the sound up to the ceiling and out to the side walls.

Remote Control

Many recent Samsung TVs come with the same minimalist remote. With this device, you will be able to turn it on and off, search for items using Google Voice, use the Home, Play/Pause, Mute, Volume, Channel, and Number buttons. There will also be a Back button, direction arrows, and an OK/Select button to select what is highlighted on the screen.

You have to press multiple buttons and wade through menus to get to the picture menu with the minimalist remote, making selecting anything a bit cumbersome. The Samsung Remote I used had a dedicated picture menu button, so I resorted to using that instead, which was left over from a trashed, old plasma HDTV. Some of the pain was definitely alleviated by this.

Nevertheless, the modern design will appeal to those who are interested in such things, and your coffee table or credenza will look nice with it.

User Interface and Menu System

People who have experience with Samsung displays will feel at home here because the User Interface and Menus are consistent with them. The options were easy to navigate and changes were easy to make.

In addition to three HDMI inputs, the LSP9T supports eARC on one of them. Projectors with at least three HDMI ports are definitely a big hit with us.

Besides the optical audio output, there are USB sockets, Ethernet ports, F-Type coaxial cable inputs, and Samsung service ports.

A bright, open environment, such as a board room or a room with many windows or light fixtures, is ideal for using this product. Slideshows, charts, and other graphic presentations. In bright rooms, it makes the colors “pop” by boosting peak brightness. Colors are unnaturally vibrant and overly bright.

Standard Mode

The screen shines best in rooms where ambient light is subtle, such as sconces on dimmers, but not so strong that it washes out the picture. You may also need ambient light for multitasking or interacting with others while watching sports or TV.

To give a more pleasing presentation, this mode simply boosts up the blue to make it look cooler while also reducing ambient light. There may also be a slight increase in black levels.

In this mode, the image looks like Film or Cinema, however it is cooler, more blue, with a higher brightness, which helps offset the effects of room lighting. Compared to Dynamic Mode, this has a more natural tone.

Movie Mode

If you prefer the standard mode, but are watching in a darkened or controlled room, then this mode is for you. In the evening, with the lights off, maybe in the same environment.

Bringing it closer to D65 white point, it tones down the brightness. There is a closer match between ideal colors and natural colors. It still has cooler (more blue) colors, but it doesn’t seem to be as bright or as close to Standard Mode’s white point as it used to be.

Filmmaker Mode:

When in Film mode, the picture is rendered as close as a manufacturer allows to the film maker’s intent in a dedicated, blacked out room.

In this mode, all processing is disabled (or at least it should be!).  The projector is supposed to be calibrated to the closest color gamut to standard, without being overly bright or clipping at the highest or lowest frequencies.

In default settings, this mode appears less dynamic and more “celluloid-like.” However, the colors are much closer to the reality than other modes. Some people don’t like being honest, so they don’t like this mode.

Game Mode:

First person shooter type games, as the name implies, are popular among gamers who are looking for the smallest lag possible.

A clear path from the game controller to the display chip allows the fastest image display and rendering from this mode, which defeats nearly all processing in the projector. HGiG (HDR Gaming Interest Group) mode can also be activated on the projector and game console.

Its appearance is similar to Standard mode, while the way it deactivates most/all processing functions is similar to Filmmaker mode. The appearance of the device is cooler unless it is calibrated or altered manually.

Game Mode on the LSP9T is my favorite picture mode. Especially when calibrating with HDR, this mode gives the image a sharp, clean, detailed look, as most “special features” are disabled. Comparatively, the other modes look harsher and more digital.

SDR (Standard Dynamic Range)

With its overblown colors, too-blue images, and boosted mid-tones with a slight magenta cast out of the box, SDR on the LSP9T is about as accurate and pleasurable as HDR. A majority of the Color Saturation points are outside of the Rec.709 range instead of near the full BT.2020 range. There is a less oversaturated look in the image due to the closer saturation sweep points, but a calibration would have been helpful.


With calibration, both grayscale and color gamut match, similar to HDR. At its peak, there is a small issue with accuracy, but the sweeps track pretty well. Greyscale is flat throughout the range, as it should be. As a result, the gamma throughout the spectrum is spot on, resulting in beautifully rendered and spec’d images, and this is evident when you watch what is possible in real life. Using the white balance, I flattened it out and it produced a very impressive result!

With its overblown colors, too-blue images, and boosted mid-tones, HDR on the LSP9T is pure eye candy out of the box. Moreover, this model had an extreme red laser, which resulted in a slight magenta cast. However, the image itself is quite pleasing to look at and it is hard to tell that it was so inaccurate.

As soon as the image is calibrated, it is even more pleasing, and more accurate too! Despite the tone mapping, there are only slight bumps and inaccuracies in the midranges where the greyscale is kicking in. As far as the upper and lower ranges are concerned, it is flat.

However, in real life watching I find that the image is not brighter than spec’d. And that it actually adds more punch to the overall image, as some say, even though this is not accurate. After flattening it out using the white balance of 10 points, it made the images appear lifeless and flat. It is likely that I could get it close to perfect in terms of measurements and appearance if I had more time.

To Sum It Up

With its 4K UST resolution, this projector  is undoubtedly one of the best projectors you can buy right now. Therefore, it comes with a price tag of $6,500 as well. A Samsung Premiere UST costs more than twice as much as a LSP7T UST.

Those with limited means or those seeking the best value for their money may find this projector beyond their reach.  The “Best” ultra short throw projector, this is one of the best contenders.

It is strongly recommended that you pair this projector with a genuine 4K+ UST ALR screen. This is important when operating in a moderate to well-lit environment.  These surfaces include Elite Screens DarkStar UST (not their CLR) or Spectra Vantage (not Stewart Balon).
