amazon Optoma S315 reviews
The Optoma S315 has a soft, color quality that fits the needs of data presentation. But the image detail is still limited by the limited resolution support.
The Optoma S315 is an multimedia projector designed specifically for small and medium businesses as well as the educational environment.
Technically, the S315 is also Optoma apply DLP technology (chip DMD size 0.55 “) featuring 3D Ready. The machine has a high brightness factor, which promises good presentation even in environments with many auxiliary light sources. In addition, the lamp used by the S315 has a long service life of 6,500 hours in Dynamic mode. However, the highlight of the S315 is BrilliantColor technology, 2nd generation integrated technology combined with 6-wheel color wheel rotation speed 3x (10,800rpm) not only helps to reproduce the full color picture More images – but also ensure smoother reproduction of moving images when playing high-definition video.
Although it is a multimedia projector product, Optoma only limits the standard resolution of the camera at the SVGA (800 x 600 pixels) level with 2 popular aspect ratio slides. The current is 4: 3 and 16: 9. In addition, the number and variety of video and audio interfaces are at the most basic level. But in return, Optoma is equipped with protective bag is very suitable for users who do not need to put a fixed machine, often have to move.
Actual touches show that the S315 has a simple exterior design but requires a lot of room to use because of the device’s appearance. The camera also features a 1.1x optical zoom lens that fills the inside of the camera body with a large zoom ring, eliminating the need to add an external protection cap.
Throughout the installation and connection process, in general, the Test Lab feels comfortable with the design of the entire communication port on the left edge of the machine, “fit” for users who need to put machine close to the wall. Optimize slide show size. In addition to the ceiling mount design, the Optoma S315 can also be positioned on flat surfaces and tilts the frame quite easily – as the two rubber feet on the rear side also allow for custom height adjustment. After about 30 minutes warm up to ensure stable image quality during testing – Test Lab found that the machine is running smoothly, but the amount of heat radiated quite large.

Presentation quality
Since it is equipped with a large range of lenses (1.95 ~ 2.15: 1), the distance from the camera is about 240cm and the S315 is just 125cm wide. To put it simply, if you want to have a large frame, you need to move the camera further away from the screen.
At first glance through the machine control menu system, it can be seen that the console does not change much compared to the individual versions of each test. Still a tabbed tab design with detailed items for each layout card is quite simple and easy to understand.
With default settings for color quality, presentation mode, brightness and contrast, the S315 offers a high brightness setting. Try the slideshow in low light conditions, the default settings of the machine show the overall color quality is quite courtesy, good homogeneity. Grayscale gradients can be easily distinguished from the naked eye without any calibration. The color changes of the black, though quite small, also gave the same result. But hot colors with the default “Presentation” presentation set show a slight lack of saturation and black remains somewhat lacking in depth. In terms of detail, due to the limitations of the resolution of the support, so if observed from a distance of less than 2m, the naked eye can still see the pixels on the screen; Of course, small lettering will suffer from slight aliasing.
However, given the cost and results of the data presentation tests, it can be said that these are not significant limitations. Even some of the higher-end models with a slightly higher price range sometimes have some drawbacks in reproducing dark detail. Under the condition of projection under the influence of some auxiliary light sources, S315’s slide quality as well as frame brightness are not affected much, generally enough to meet the needs of using the machine in the meeting room / Classrooms have many light sources.
Although designed primarily for data presentation needs, the S315 still play “quite well” some HD content as well as Full HD 1080p is often tested. However, fast-moving Full HD footage is sometimes still lightly jerky. The quality of the built-in 2W speakers is also limited, so it’s best to use standalone audio systems.
The Optoma S315 is quiet, fast startup and shutdown, and color quality fits the needs of data presentation in small to medium classrooms. However, if there is a high demand for image detail, users can choose models that support higher resolutions, such as the X316, which has many similarities but requires a small fee.
