With the advent of the product, players who are concerned about the market dynamics may have noticed the official half-price trial activity recently, that is, they want an 8-inch 1280? H 1000FHDT is suitable for 768 resolution screen. At first glance, the product takes the screen as its selling point. Its screen size is larger and the resolution is higher than the new flat U9 under the same brand. It has the ability to decode high-definition video, mainly for car and home users.

outer packing

The packaging of H 1000FHDT is the same as that of Tongping U9. The box is flat and quite large in size. Suddenly feel that you are actually holding a netbook? Unified design highlights the brand, but it is not intuitive relative to the product. If you don't open the box, you can only tell the model from the side label.

All accessories

Accessories of this product include independent power supply, USB transmission line, screen film, earplug (white with ear cotton), warranty card, user guide and special leather case. Among them, the external power supply comes with its own independent packaging, and the original leather case is designed to turn pages, so it can be placed on the desktop as a product bracket without taking it off, but the bracket angle cannot be adjusted.

Fuselage appearance

The mainframe of H 1000FHDT is very flat. The size of an 8-inch screen is not bragging. The upper and lower sides of the screen are wrapped in silver metal, which not only protects the fuselage, but also makes the border part more narrow and exquisite, and the visual effect is quite excellent.

loudspeaker

Without the color contrast between the left and right sides of the screen, it is wider and the lines are more rounded, which makes this 8-inch screen product much softer. The built-in speaker is designed on the left side of the screen this time, which supports external playback, but the effect is average, the volume is small, and the sound is interrupted when it is adjusted to the highest volume.

Appearance and interface design, etc.

Fuselage backboard

The shape of H 1000FHDT is excellent in this size product, and the metal wrapping on the edge is the finishing touch. The rounded lines on the back cover not only increase the affinity of the product, but also make the fuselage look more stereoscopic, fashionable and friendly. The pure black matte shell has an extraordinary temperament, but it is easier to leave fingerprints, and the mirror panel also has this problem.

Right fuselage interface

The product interface is mainly on the right side of the screen, which is easy to identify through text prompts. Includes OTG, USB, DC, HDMI, video output and standard 3.5mm stereo jack. TF card slot is on the back cover.

Right button of fuselage

The TF card slot is hidden at the edge of the back cover, and the close-up photo is of course more eye-catching. The real thing is very low-key, the dark shell is not eye-catching, and it can be blocked by holding it.

Ultra-thin fuselage

H 1000FHDT adopts full-screen touch operation mode, with auxiliary mechanical buttons on the left side of the screen, namely on/off, back, menu and desktop buttons, and infrared receiver and power switch at the other end of the fuselage.

Interface details and TF card expansion slot

The shell material of this product is mainly plastic, but the volume is here, and it must still have a certain weight in your hand. Initially, I wanted to match my product with an optional Mo Fan flannel bag. Unfortunately, the mainframe of H 1000FHDT is thin and long, and there is no suitable number. Let's use the official leather case. It looks ordinary, the size can be appropriate, and it comes with a bracket, which is more practical.

Screen viewing angle

frontal eminence

Does the Kubi Rubik's Cube H 1000FHDT have 8 inches 1280? 768 resolution screen, huge screen, good vision and high resolution are the main selling points of this new product. The fineness, color and brightness of the screen look excellent, especially when playing HD video. The viewing angle from left to right is still excellent, and you need to put the bracket on the desktop to watch it.

Product screen display effect

Since it is a product with screen as its selling point, let's take some photos of the screen display effect for your reference. H 1000FHDT has a large screen size and high resolution. If you look at the picture, it is still a little greasy, and the video effect is better.

Desktop menu integrated with plug-in

Desktop system

Desktop system

The menu design of H 1000FHDT is one of the product features in the e-book interface. The product desktop integrates Widget controls, giving people a more flexible feeling. Through the plug-in, you can directly control music playing, backlight and volume adjustment on the desktop, and it has an automatic picture playing window and calendar. What is more interesting is the content on the third page of the desktop. H 1000FHDT actually draws a screen directly for the text reading list and directly opens the built-in e-book. Its interface is similar to the bookshelf design of the famous reading software iReader.

Music playlist

The main functions of H 1000FHDT are music, video, picture browsing and text reading. Players will see it more intuitively after entering the function menu. These four functions can be switched directly in the left column. In addition, the path selection is now changed to the way of label switching instead of the usual menu options. The picture above is a photo of the audio playback function. H 1000FHDT still supports the function of media library, which can retrieve audio files according to information such as artists and albums, but this function is limited to files on local disks.

Music playing interface

The product's playback interface can display the status bar. In addition to volume adjustment and menu virtual keys, you can also check the clock and power indicator light, which is quite convenient to design. There are also shortcuts to switch sound effects and playback modes in the music playback control bar.

Music playback test and video settings

H 1000FHD

The audio playback settings of H 1000FHDT provide functions such as cycle mode selection, sound effect switching, LRC synchronization lyrics, backlight adjustment, star setting, etc., and support random playback. Among them, the LRC synchronized lyrics are automatically switched and displayed by the product, and the manual setting is for users who don't want to see the lyrics. In addition, there are many color schemes for displaying lyrics that can be replaced. Music files without lyrics display file parameters and ID3 information. Unfortunately, this product can't display album covers at present.

Video playback options

The video playback function gave Xianglong a small surprise. The prototype plays 1080P full HD movies without pressure, and the picture is dark and smooth, so we don't waste our 8-inch screen. Functionally, it supports audio track switching, plug-in subtitle display, backlight adjustment, display scale switching and channel switching. There are also three font sizes of plug-in subtitles.

Video playback options

It is estimated that the sample firmware sent for testing is not perfect, and this version of firmware H 1000FHDT also has many imperfect problems. In the test, the actual content has not changed but the menu has changed after multi-track switching, and the external subtitles will disappear as long as the length exceeds the play icon. These two can be said to be the main problems encountered in the test. The scheme of H 1000FHDT is very mature and I believe it will be solved soon.

Video playback effect

There are still some details that need to be improved, such as bilingual subtitle display, adding color adjustment to fonts or shadow effect of brush strokes. Later firmware hopes that manufacturers can join in. Although the font size is variable now, the pure white color is easily confused with the background, and the subtitle content cannot be displayed when the control bar is called up. Fortunately, this version of firmware supports manual hiding, and you can switch the status of the control bar by clicking on the blank space of the screen.

Video playback test results

See the following table for specific video test results. In addition to some setup problems mentioned above, H 1000FHDT is a very powerful machine in decoding ability, so it is not a problem to play full HD. Remind you to watch more HD videos. This product has high screen size and resolution, and the effect of playing high-definition movies is excellent, but relatively speaking, the video quality can't keep up with the effect, but it will be greatly reduced.

Picture browsing and text reading functions

Picture browsing

At present, the image browsing function supports four formats: JPG, GIF, BMP and PNG. Except for the slow loading speed of PNG, the opening speed of photos in other three formats is quite good, but the file resolution is more or less limited except JPG. At present, the BMP format can be opened up to 1895? 1288 resolution file; GIF can be opened 1680? A picture or animation with a resolution of 1050, but the animation file cannot be played normally, and the animation can be played normally up to 1400? 875 resolution, but the playback speed is obviously slow; PNG format can now be typed as 205 1? The loading speed of a file with a resolution of 1457 takes about 4 seconds.

Picture browsing function

By default, the virtual operation keys in the above figure are not displayed. You can invoke them by selecting View Actions from the menu. In addition to the functions of background music, automatic playback, zooming and rotation, you can also switch files by clicking on the left and right edges of the screen, which is very convenient to design.

E-book list

H 1000FHDT has strong writing support. E-books including TXT, LRC, PDF, CHM, PDB, EPUB and FB2 can be loaded normally, and files with chapter information will be merged automatically. As far as its experience is concerned, H 1000FHDT has advantages in similar models and even low-end e-book readers. Friends who attach importance to text reading can experience it for themselves.

Electronic book browsing

Text file settings include auto play, font size/color adjustment, independent bookmark, background switching (customization, backlight adjustment and font width modification are not supported. PDF files support independent bookmarks, automatic browsing and backlight adjustment without automatic typesetting. Incidentally, in several other e-book formats where pictures can be inserted, most of the pictures can't be displayed normally, so it's best not to choose this illustrated file to use.

Watch the PDF magazine vertically, but the menu is still displayed horizontally.

Auxiliary functions such as FM and recording.

H 1000FHDT has many auxiliary functions, such as OTG, video output, infrared remote control and so on. It's a pity that you have to buy your own accessories. Hehe ~ It is also convenient to have a calendar, clock and constellation on the desktop menu, and it also supports FM FM radio and recording products.

Frequency modulation

The interface of FM radio is quite intuitive, which supports automatic and manual channel searching and can save the list of stations. I personally like its tuning progress bar. When setting manually, it is not necessary to press it once. Just click the progress bar first, and then fine-tune it with the keys. The listening effect is shown in the table below, and the overall feeling is good, only the signals of individual stations have obvious influence. When moving, the channels with good information will not change obviously, and the channels with big differences are basically channels that were not found at first or received with problems.

Beijing People's Broadcasting Station Traffic Station 103.9 Sunny

The first program of china national radio 106. 1 is a little noisy.

China People's Broadcasting Station's Voice of Literature and Art 106.6 has serious noise.

FM recording

The design style of recording interface is very similar to FM radio, which is a relatively intuitive way. The front function of the left column is the radio station list, and the recording is the recorded voice file list, which can be directly auditioned. You can also modify the recording quality through the menu, which can be divided into three modes: high, medium and low, and the file is saved in MP3 format.

Built-in calendar, the interface can be called up by clicking the tool icon bar on the left side of the desktop, and the calendar plug-in is not linked to this interface.

Video output list

As can be seen from the menu of video output function, H 1000FHDT supports three output modes: AV composite, color difference and HDMI, and has good compatibility, and supports full HD digital output, but the corresponding accessories (including video cable, infrared remote controller, etc.). ) users need to buy it themselves. It would be nice if there is a special accessory package to sell, and it will be done at one time, and the manufacturer's package should be considered ~

The product has built-in battery status monitoring, which can accurately display the battery usage status.

System settings, USB transmission

System setting interface

In addition to the above-mentioned video output settings, the system settings menu of the product also includes menu language selection, timed shutdown, FM transmission, automatic screen shutdown, tone switch operation, backlight adjustment and color temperature setting. The battery information, calibration, system information query and factory settings in the left column are not tabs of other interfaces. Click to start the corresponding function directly. It is estimated that this arrangement is so that all options can be displayed on one screen. Use it quickly ~

The screen backlight of this machine is as high as 15 brightness level.

Color setting is rare in similar products.

Data transmission test

H 1000FHDT adopts high-speed USB2.0 transmission interface. After software testing, the fastest random writing speed is 3487KB/S, and the fastest random reading speed is11033 KB/s; In practical application, it takes 96 seconds (about 1.94MB/s on average) to copy an independent 186.4MB file, and 6 1 s (about 6.03MB/s on average) to copy three files with a total of 368MB, which means that the above test has been done three times. Is it true?/You don't say.

Cool cube H 1000FHDT

Kubi Rubik's Cube has always advocated the popularization of products. H 1000FHDT is also a product for ordinary home users, and the listed price is only 699 yuan (8GB). Now it's only 349 yuan to participate in the official half-price trial. Sounds attractive, doesn't it? The screen resolution of this product is the highlight, but Yi Long pays more attention to appearance. 8-inch screen products can actually give people a sense of fashion and thinness, which is quite rare in similar models. Coupled with powerful video decoding capabilities, the experience is quite good. Of course, the firmware of the beta version needs to be improved.
