Body design and function
Figure 1: The optical lens is located in the center of the front of the projector. The same as other Sony 4K models, this lens is still a fully electric lens, including zoom, focus and lens shift functions can be achieved directly through the remote control
Fig. 2: The fuselage function keys are still retained on one side of the camera body, even if the remote control cannot be found
Figure 3: On the other side of the fuselage, all I/O interfaces are centralized, including two HDMI video input interfaces, all can support UHD 4K HDR signal input, and also include various control interfaces to facilitate the home Intelligent control system integration
Figure 4: At the rear side of the fuselage, the body fan for heat dissipation can be found from the grid. This means that when the user is installing, it must leave enough space at the rear to avoid affecting the heat dissipation and stable operation.
Laser and 4K SXRD top configuration,
Main vacancies in the high-end market
VPL-VW768 has two high-end home theater projectors in the fuselage: the laser light source and the native 4K display chip. The former solves the problem that the bulb lamp has a short life span and the color gamut can not be further improved. The latter can fully display the exquisiteness of the 4K ultra-high-definition picture. However, in the current market, home theater projectors with these two advantages are expensive, often more than 200,000 yuan. The appearance of the "parity high-end" VPL-VW768 under 200,000 yuan made the audio-visual enthusiasts who were still in the wait-and-see phase begin to stir up, and many people had the will to upgrade the main machine at home. However, compared to Sony's flagship VPL-VW5000ES, many players are skeptical that the small and exquisite VPL-VW768 has enough screen-shaping power to meet the large screen projection of 150 inches or more.
Screen adjustment main functions
Figure 1: In the screen adjustment function, VPL-VW768 and Sony's other 4K home theater projector is not much difference, the basic features include contrast, brightness, color, hue, color temperature and sharpness, which is worth Note that when you access the HDR source, the contrast item becomes the contrast (HDR)
Figure 2: For different application requirements, up to 8 screen modes are preset in the body, and a separate user mode is reserved for user-specific adjustments.
Fig. 3: For the control of the laser light source, in addition to the fully manual independent adjustment method, it also has a dynamic control mode.
Figure 4: Into the dynamic light control menu, you can choose to fully control or limit the control of two different levels of dynamic light mode, in order to enhance the dynamic contrast of the picture
Figure 5: In the fine-tuning of the color temperature, the classic 2-point gray-scale white balance adjustment function is configured to fine-tune the highlight and dark parts.
Figure 6: In addition to the color temperature fine-tuning function, in fact, VPL-VW768 also has a complete color management system, you can enter the color correction project, respectively, the RGBCMY 6 color gamut space to fine-tune to obtain more accurate color performance
Figure 7: In the HDR state, after selecting the BT.2020 color gamut, you can fine-tune the gamut space with RGB three colors.
Figure 8: As the United States and Europe gradually announce that HLG will be adopted as a TV broadcast HDR specification, it is becoming more and more important to be fully compliant with HLG. The VPL-VW768 fully supports HDR10 and HLG.
Only need to achieve a reasonable adjustment of the picture,
The overall picture of energy will make you greatly improve
For this purpose, we specially matched a 150-inch (16:9) non-sound screen OS BU201 with a gain of 2.7 during the test, and selected the preset movie film 2 mode for viewing, which confirmed the overall transparency of the picture. Not so prominent, it can be said to be a good shot when shooting a large 150-inch screen. With regard to the high-end models in this price segment, it is obviously not enough for the finicky fans to satisfy their appetite. But is this really all the strength of the VPL-VW768? After more than 3 hours of full-screen grayscale, dynamic range, and color adjustment, the overall picture's brightness and transparency have been significantly improved, especially when watching HDR10 specifications UHD 4K ultra-high-definition Blu-ray movie blockbusters , Can better release the bright sun and energy. In the HDR mode, such a huge change made me very surprised. After carefully reviewing the test results, I found that before and after the screen was adjusted, the actual brightness of the screen (the brightness of the reflected light from the screen is not the projection brightness of the projector) increased by more than 1 times. From the perspective of perception has been quite close to the previously tested VPL-VW5000ES. Therefore, for those enthusiasts who are considering whether or not to prepare for this projector, my opinion is that there is no need to hesitate, but it is recommended that a full screen adjustment be made to fully explore its potential in terms of image energy.
Using ChromaPure3 Professional professional video tuning software with X-Rite i1 Pro2 spectrometer, X-Rite i1 display pro3 colorimeter, Murideo Fresco Six-G 4K HDR signal generator tested in SDR gamma2.35/D65, HDR10 Gamma (EOTF )/D65 grayscale white balance performance
In the SDR (non-HDR) state, the movie film 2 screen preset mode and Gamma 2.2 mode are selected and adjusted by the 2-point grayscale white balance function. The corrected Gamma gray value is around 2.35 of the set standard. , and the overall grayscale white balance transition is relatively stable
In the HDR state, select the movie film 2 screen preset mode and adjust it with the 2-point grayscale white balance function. The corrected Gamma (EOTF) grayscale curve starts to roll down from 70%, and is close to 50% or less. In the HDR10 standard, the overall picture details are better, regardless of whether the highlights or shadows are quite rich, and the highlight light energy is more prominent
Use ChromaPure3 Professional professional video calibration software with X-Rite i1 Pro2 spectrometer, X-Rite i1 display pro3 colorimeter, Murideo Fresco Six-G 4K HDR signal generator to test various screen preset modes in SDR BT.709 color Domain standard, performance under HDR DCI-P3 color gamut standard
Fig. 1: This is the color gamut test chart of the preset mode of the movie film 1, although the color gamut range is bigger, exceeds 118% of the BT.709 standard, but the overall color balance can maintain a better level, slightly less is The blue color is slightly lower and the white dots appear slightly yellow
Fig. 2: There is a big difference between the preset mode of the motion picture film 2 and the mode of the motion picture film 1. Since it is closer to the BT.709 standard, this is an adjusted test pattern. The visible color gamut is very close to the BT.709 standard, and the white point is positive. In the D65 position
Figure 3: Bright Cinema Preset Mode As its name suggests, the overall screen brightness is higher, the screen colors are more vibrant, and the color gamut is larger, reaching 115.4% of the BT.709 standard, and the white point position is also accurate.
Figure 4: The original preset mode belongs to one of the more accurate color modes. The color gamut is close to the BT.709 standard, but the white point also appears slightly yellowish.
Figure 5: The bright TV mode is similar to that of a bright movie theater. The brightness of the overall picture is higher, which is higher than that of the bright movie theater mode. The picture style is biased toward the vivid style, and the white point appears slightly bluish.
Figure 6: The overall color of the TV preset mode is not as bright as the bright TV mode, but the balance is good. The color gamut is larger than the BT.709 standard. The white point also appears blue.
Figure 7: Gaming preset mode has a large range of color gamuts, and the overall color is brighter, especially red and green, and the white point appears slightly yellowish.
Figure 8: In the HDR state, we chose to adjust based on the film 2 mode. The adjusted color gamut range is close to the DCI-P3 standard, reaching a color gamut size of 90.4%. The white point is close to the D65 level. Slightly yellowish
Bright and transparent but not strong style,
The scene reveals the sense of familiarity belonging to Sony at all times
The color style is a place where AV enthusiasts are very much concerned. In fact, the overall style is still familiar with Sony style. The color is transparent but not strong, but this projector in the green and red aspects of performance Compared to Sony's other light bulb 4K machines, it is significantly brighter and more dynamic, especially when it comes to displaying nature and cartoons. In terms of the key skin color rendering, the VPL-VW768 can show the difference between different people's skin color regardless of the HDR state or the HDR state, but relatively speaking, the skin color description in the HDR state is more delicate. In addition, the dark part of the picture and the highlight layer transition smoothly, and it is possible to retain a considerable amount of detail and is satisfactory.
UHD HDR10 screen actual skin color and sharpness fine-tune
Since the main viewing content is UHD 4K ultra-high-definition Blu-ray source using UHD HDR10 specifications, in the aspect of picture testing, the dynamic range of the picture is specially adopted by the testing software of "R.Masciola's HDR-10 UHD Test Patterns Suite". Fine-tune the skin tone and sharpness, allowing it to maximize the detail of shadows and highlights in the HDR high dynamic range film source while maintaining optimal skin tone and sharpness
In addition to HDR10, it also includes HLG
Prepare for the future
In the end, let's talk about one of the important features of the VPL-VW768 that can be easily overlooked. This is the ability to support the HLG specification. Although Sony's 4K home theater projectors are now able to support HLG, they are still in the minority in the market. HLG (Hybrid Log-Gamma) is an HDR standard applied in European and American radio and television systems. It has gradually been extended to certain countries in Asia. In the future, there is a great possibility that it will become a technology for domestic 4K HDR television broadcasting. specification. However, in terms of actual picture quality, the high dynamic range effect exhibited by HLG is still a lot longer than that of HDR10, but it is compatible and it is also another bright spot of VPL-VW768.
