Color is the core? ViewSonic 1080P home projector evaluation

Although laser television has become the focus of the projection industry, the 1080P home projection of traditional light sources is still a cost-effective choice for many big screen enthusiasts. This type of home projector resolution and practical, brightness effects are also suitable for home, and now many brands have optimized the color performance of 1080P home projectors, such as the ViewSonic PX726HD we want to test today.

The ViewSonic PX726HD features SuperColorTM Super BrightTM and RGBRGB color wheel and bulb adjustment technology to demonstrate a wider color gamut. ViewSonic also stated that the PX726HD supports the Rec.709 and sRGB color gamut standard range. The specific role of Rec. 709 is to specify the relevant color gamut, resolution, frame rate, and display specifications, making the picture transition natural, for a home projector. This color performance is very meaningful.

Just knowing the brightness performance is not enough to understand the overall performance of the ViewSonic PX726HD. After all, the highlight of ViewSonic PX726HD is the color, then we will enter the evaluation of ViewSonic PX726HD. ViewSonic PX726HD also supports 1920Ã—1080 high-definition resolution with a nominal brightness of 2200 ANSI lumens and a lens projection ratio of 1.1 to 1.5. It also supports up and down screen displacement and supports keystone correction. After testing, the measured ANSI brightness is 1519 lumens, that is to say in the color optimization mode, the picture has a brightness of 1519 lumens. The peak brightness of the ViewSonic PX726HD reaches 2648 lumens, and the maximum brightness is 2,079 lumens.

ViewSonic PX726HD Remote Control Backlight

ViewSonic PX726HD's remote control is also a white design, key design is reasonable, use up and learning cost is not high. It is also worth noting that the remote control of ViewSonic PX726HD has a backlight function, as long as you press any one button, you can achieve the blue backlight light, for home projectors often operate in the dark, this feature is also very worthy of recognition.

ViewSonic PX726HD is a product with unique advantages in color, it has a variety of display modes, different adjustments for color. Users can feel their actual hobby to choose. It is divided into five modes: brightest, dynamic, movie (Rec.709), standard, and Viewsonic sRGB. For these five modes, we also specifically made a real shot.

Color mode between different modes

The real shot can be found in the ViewSonic PX726HD has a variety of color modes, even in the brightest mode, although the color temperature has been significantly higher, but the dark parts of the picture are not all missing, this brightest mode is still of practical significance. Unlike most projectors, the brightest mode screen details are no longer visible. Of course, we are most concerned about the ViewSonic PX726HD sRGB mode, I also specifically tested this mode.

ViewSonic PX726HD Movie (Rec.709) Color Mode

Can be found through real shot, ViewSonic PX726HD sRGB mode color performance is very characteristic, red is more infectious than the original picture, the color of the entire picture is relatively transparent, whether it is distant scenery or near details, color performance There is not much difference between the original picture and the author. I think that this mode can be used to watch movies and can basically appreciate the original color style of the movie.

Then we savor the color of the ViewSonic PX726HD. Color testing is one of the most important test items in the evaluation process of the projector. It mainly examines the color reproduction ability of the projector and the color saturation, lightness, color richness, and color temperature by comparing the test proofs with the color real shot diagrams. The level and so on. Let's take a look at the performance of the ViewSonic PX726HD in terms of color.

The left side is the real shot of the test sample right side

Through the above three sets of comparison charts, we can clearly find that the ViewSonic PX726HD's color is very transparent, high color brightness, while color reproduction can also meet the needs of large-scale movie viewing. Especially for the reduction of human skin color, although the performance of ViewSonic PX726HD can not be said to be 100% proofs, but its color is more pleasing to people.

The left side is the real shot of the test sample right side

In the comparison of four-color maps, we can see that red, green, yellow, and blue are actually very good. Although it can be seen from this figure, the brightness of the ViewSonic PX726HD is dark in the middle, but the overall accuracy of the restoration The ViewSonic PX726HD doesn't have much to be picky about.

Projector Data Testing We mainly use the ANSI standard developed by the American National Standards Association. This standard is also recognized as an authoritative standard in the industry. And consider the following aspects: maximum brightness, peak brightness, optimized brightness, and projector contrast color. Next, I will briefly explain a few technical terms for everyone: The first is the peak brightness, especially in the brightest mode, the highest brightness can be achieved at a single point, generally appear in the center point; maximum brightness, refers to the brightest mode The average brightness that can be achieved on the screen is higher than the reference value of this value; the optimized brightness, also known as ANSI brightness, is the average brightness of the 9 test points in the case where the projector can just distinguish eight gray scales.

Two different contrast test methods

data analysis:

With regard to the brightness of the projector, there are three data in the table, namely the maximum brightness, the peak brightness, and the ANSI brightness. In simple terms, the maximum brightness is the average brightness of the screen in the brightest mode of the projector (brightness, contrast, and lamp mode are all adjusted to the maximum). For home projectors, this data is in an excellent range if it can achieve about 90% of the nominal brightness. From the results of our actual testing, the ViewSonic PX726HD has an ANSI brightness of 2,079 lumens and a brightness of 94.5% of the nominal brightness (2,200 lumens).

Peak brightness refers to the maximum value that can be reached at a certain point on the screen in the brightest mode. In general, peak brightness is best if it can approach 95% of the nominal value or even exceeds the nominal value. From the actual test data, the peak brightness of the ViewSonic PX726HD is 2648 lumens, exceeding the nominal 2200 lumens, outstanding performance.

ANSI brightness refers to the average brightness of the 13 test points in the picture when the projector can just distinguish eight black and white blocks. Therefore, ANSI brightness and maximum brightness are more significant for our reference. In general, ANSI measured brightness is qualified if it can reach 60% of the nominal value and 80% is excellent. The measured ANSI brightness of ViewSonic PX726HD is 1519 lumens, which is 69% of the nominal brightness. For a projector that emphasizes color, the ANSI brightness compliance rate is very good, because the color and brightness cannot be taken into account at the same time.

After reading the dry goods data, the author brings the real shot effect of ViewSonic PX726HD. From these real shots, you can appreciate the color performance of ViewSonic PX726HD.

ViewSonic PX726HD real shot map

From the real shot screen of the ViewSonic PX726HD, we can see that the color performance of this product is really good. Under the mode of accent color, the picture color is very appealing and the color is clearly structured. Color reproduction accuracy is also worthy of recognition, for entry users, such color performance can also be affirmed. Of course, if it is compared with the top home projectors, there is still a gap in its color accuracy.
