After the launch of MP4 series players with 3-inch, 4.3-inch and 5-inch screens, Onda Electronics resolutely upgraded the screen to 7-inch, and showed such a large screen to consumers with VX797HD as the product model. Of course, the screen of VX797HD follows the 800 of VX545HD. 480 resolution (16: 10 ratio), and inherited 10M bit rate 720P HD (1280? The 720-resolution RMVB/AVI movie is also equipped with an infrared remote control, which looks like a mobile cinema.

The picture image is more detailed, which reduces the fatigue of eyes. Say 800 more? The LTPS low-temperature polysilicon display with 480 resolution16 million colors also gives full play to the shocking effect brought by the 7.0-inch high-definition screen, and the viewing angle is as high as 170 degrees, presenting wonderful pictures in all directions. Furthermore, the body of VX797HD is ultra-thin, which reduces the portability problem caused by the huge body.

"Huge fuselage, exquisite workmanship:
Onda 7-inch 720P VX797HD (click here to view larger image.
)
Literally, the size of Onda VX797HD with a 7-inch screen should be difficult to estimate. So we compare two MP4 players, VX535HD with 4.3-inch screen and VX555HD with 3-inch screen. The above picture shows VX797HD, VX535HD and VX555HD from left to right, so the huge body of VX797HD is self-evident.
Onda 7-inch 720P VX797HD (click here to view larger image.
)
Although the body size of Onda VX797HD is quite large, its thickness is very thin, which is not much thicker than that of VX535HD and other models, but its weight is incomparable to that of VX535HD and other models. Therefore, even if VX797HD deliberately reduces the thickness of the fuselage, it is still daunting to carry in daily use. In addition, in terms of specific appearance, VX797HD follows the design of VX535HD, with the same materials, workmanship and panel treatment, and implements the exquisite technology of Onda MP4 player.
"Two speakers sound effect:

)
Like the design of Onda VX535HD, VX797HD has double speakers on the back of the fuselage, and the amplification openings of the speakers are correspondingly enlarged, so that the sound quality and volume are well guaranteed. It has also been verified in the preset songs we played on the Devil's Seat album and the songs we added ourselves, such as Hotel California and Ferry. Stereo surround sound has also been well played, and the restoration of human voice and instrumental sound is more accurate.

Onda VX797HD has a charging interface and a Mini USB interface on the right side of the fuselage, while a 3.5mm headphone interface, a 3.5mm video signal jack, a reset jack and a Micro SD memory card slot are designed on the right side of the fuselage. Among them, the video signal jack represents that VX797HD supports video signal output and can be connected to a display for movie playback.

Onda VX797HD has a common play/pause button and return button on the left side of the screen, and an infrared remote control interface is also designed below. Multimedia buttons for volume increase and decrease, fast forward/next song and back/previous song are designed on the upper side of the fuselage. The design principle of these buttons is the same as that of VX535HD and other models, but the overall controllability of the buttons is not good enough because the contact area of the buttons is not large enough and the buttons such as play/pause are a little sunken.
"Accessories, infrared remote control:

Onda VX797HD also supports video output and is equipped with two video output lines. The video cable works very well and can effectively ensure the transmission of video signals. In addition, VX797HD provides accessories such as USB data cable, stereo earphone, rag, power adapter and instruction manual. Stereo headphones are common EP50 headphones of Onda, and the sound quality is good. Of course, friends who don't like it can also change other headphones with better sound quality.

Onda VX797HD improves the screen to 7 inches, but the resolution remains at 800? 480 resolution level, that is to say, the image display fineness of VX797HD will be lower than that of VX535HD and other models, but the actual display effect is quite excellent, because the visual effect brought by the increase of visual area is incomparable to that of small screen. Besides, the 7-inch screen is the same as the 800? The combination of 480 resolution can still play a good display effect, which can be verified in the detection of the above professional test charts.

Through the test of VX797HD screen by professional test chart, we can know that the image display fineness of this screen is considerable, the color transition is natural and the contrast is well controlled. From the screenshot of the screen display effect, we can also know that the screen effect of VX797HD is quite good, 7 inches 800? The screen image with 480 resolution is exquisite, and the actual brightness, resolution, sharpness, color transition and contrast are better.

"Disk reading and writing speed measurement, battery life:
Onda 7 inch 720P VX797HD
In the process of disk speed measurement, we still use ATTO speed measurement software to test Onda VX797HD. The test results show that the highest writing speed of VX797HD is 5.23 1MB/ s, while the highest reading speed is 6.066MB/ s, which keeps the level of VX535HD and other models. In addition, the battery capacity of VX797HD is unknown, but after playing two movies intermittently (about 4 hours) and playing 1 hour music, the power consumption is about 60%, which is no wonder. After all, the power consumption of the 7-inch screen has increased a lot.
"Main menu:
Onda 7 inch 720P VX797HD
Onda VX797HD continues the design style of previous models such as VX535HD, and the design of the main menu is still very simple. The function icon is placed at the bottom of the screen and has a rotation control mode. These function icons are simple and single color, which is very good for VX797HD with replaceable desktop wallpaper. In addition, VX797HD supports music playback, video, picture browsing, recording, radio, e-books, resource manager and settings.
"Video playback function:
Onda 7 inch 720P VX797HD
Onda 7 inch 720P VX797HD
In terms of video function, Onda VX797HD supports breakpoint playback, normal, filled, full screen, normal increase by 30%, original size 150% and other 10 display modes, and also supports two kinds of HDTV outputs: color difference output and normal output. At the same time, it can directly play video files in RM/RMVB, ASF, AVI, MP4, 3GP, MPG and other formats, and support 10M bit rate 720P HD (1280? 720 resolution) RMVB/AVI movie playback.
"720P video playback measurement:
Onda 7 inch 720P VX797HD
In the actual measurement of 720P movie broadcast, we downloaded several 720P RMVB and AVI movies from the Internet, including several video coding formats such as RealVideo 4, h264, MPEG-4 Visual, etc. The specific movies include Fantasy Companion Animation Series, Xie Anqi's Zhu Yingtai MTV, New York Gangster, Handsome Guy and Banquet, and VX797HD Body for testing.
During the test, we found that VX797HD can't play movies in h264 encoding format, but it can support two encoding formats, RealVideo 4 and MPEG-4 Visual. For example, when the playback bit rate is 1 147 Kbps, the width is 1280 pixels, the height is 720 pixels, the display ratio is 16: 9, and the frame rate is 24FPS, the movie will be smoother and more comfortable. In addition, users only need to copy the movie into VX797HD memory and play it smoothly without any conversion.
When playing a movie, VX797HD supports calling up the real-time control interface (as shown in the figure below), setting the display mode, TV output type and breakpoint playback, and outputting the video to an external display (an external display requires a cable). In addition, because all the films we tested and played have detailed film information, we put these information together with the screen shots of the films, which intuitively proves the playback ability of VX797HD.

"IT 168 assessment center view:
Raise the screen to 7 inches. Onda VX797HD, 800? With the resolution of 480 as the foil, the excellent screen display effect is obtained, and the16 million color LTPS low-temperature polysilicon display also makes the viewing more comfortable and natural. Of course, the most important thing is that the support for 720P movies follows the essence of VX535HD and VX545HD. Within the scope of support, movies can be played smoothly, and functions such as music playing, radio and picture browsing also enrich life outside of movie appreciation.
However, the huge body of Onda VX797HD is not easy to carry after all. Even if VX797HD has a relatively ultra-thin body, it can't escape the trouble of huge size. However, from the price point of view, the price of the 8GB version of H797HD is 799 yuan, and the cost performance is still very good. Friends who like big-screen MP4 players can consider it.
