Before saying WiHD first talk about music max, music max is already listed in 2015, and in 2016 LeTV launched a number of so-called music max pro, using a 820 processor, was fortunate to get a , The screen is big enough, and it's fast enough. It's very suitable for the elderly. My dad always likes to drum up electronic products. He will be happy to use his new features. It's just that LeTV's software has been sending video to DLNA. The compatibility is very bad. Some software can be used for investment. Some software does not work. Therefore, my dad has been playing video games for a long time. I don't know whether it is related to the TV in my home. Android looks like a screen shot. This piece is done in a wide variety of ways. The Eight Immortals are all over the sea. It is not as good as an airplay protocol for iphone to solve all the problems.
When I first got the Max Pro, I found a WiHD module that was not on my back phone. It was very unique. I just didn't know what to do with it. I learned later that I could connect to the WiHD box to do a wireless screen. The price of 499, this price feels no need to buy the 499 can buy several TV boxes are all, but accidentally saw a few days before the Tmall New Year activities, so the value of 99 into a test water, take a look at What's the effect? ​​I'm sorry that I was very busy at the time and I didn't have time to write the news. The price was restored when I wanted to break the news the next day. . .
Shamelessly hiding
What is WiHDWiHD is a wireless high-definition video transmission protocol operating at high frequencies of 60GHz. WiHD technology can transmit high-quality, high-definition uncompressed video stably and reliably, and enables consumers to transmit and play between multiple electronic devices. Compared to Wi-Fi, WiHD has added support for 1080P and 3D, and has a longer transmission distance.
WiHD is the wireless version of HDMI, can achieve 0 delay, 0 compression of the transmitted video signal, those mircast, airplay through wifi to screen, due to the limited rate, the picture has to be compressed, in the transmission, and finally unzip, delay and frame Rate can not go up.
At present, there are very few products that seem to support WiHD, so this is a very niche product. If you also have a WiHD device, you may consider using one.
Link diagramThe structure is very simple, it has a Y-type HDMI cable, one is the HDMI port, the other is the HDMI and USB ports, the USB port is to rely on the TV's USB port to power the device, this device's power consumption is only 3.3W, so TV's USB only needs to provide 660mA, it should be stress-free
When it came out, it was LeTV's box, or it was easy to pull, and every time the box was opened, it was so cool!
In fact, there is a small box inside
Forgive my dust on the table
Why did you just turn on so much gray
There is also a special Y-shaped HDMI cable. If it's broken, it's not very good. . .
Workmanship is good, aluminum alloy shell is very texture
There is a non-slip mat underneath, but the weight is too light to be run around by the HDMI cable
The whole machine has only one RESET button. Unlike the RESET of the router, it needs to take the toothpick bucket PP. Its key is also metal, and the texture is very good. However, the usage of this button is as simple as the router, and it takes 10 seconds to restore the factory. Settings, but in fact there is no need to set up this device, I do not know why you need to restore the factory settings. . .
The method of use is very simple. First, the WiHD screencasting artifact is connected to the TV. The usb port must be plugged into the TV. Of course, it can be plugged into other mobile phone charging heads. The USB cable is very short, so it is still inserted into the TV. It will be more convenient
Do not need to boot, even after a good line of WiHD artifact will have a green LED flashing slowly, this time open the phone's settings - more - wireless display, open WiHD inside
Normally, you can search for a device and click it to connect it.
However, it should be noted that if your TV's HDMI cable is not connected properly, it may not link to the situation, causing me to close for a long time are not connected until they found that the HDMI cable is not inserted
Usually dissatisfied with the screen, when the phone enters landscape mode or full screen when the TV can be full screen display, when using the mobile phone comes with the player, the phone screen will automatically turn off the backlight power saving, off the backlight after the screen can still see very Dark picture does not automatically turn off the backlight when using other players
Let's talk about the effect below. The operation on the mobile phone in use can be very smooth and synchronized with the television, and the picture quality is impeccable. If the signal is good, we can't find a little bit of it. Airplay is currently relatively cool in my screencasting. However, when playing video, there will still be a slight card or a card. It may also be caused by the speed of the soft solution airplay protocol. After all, there is no apple tv to do the comparison. Wifi transmission speed also has some limitations. For me, spikes airplay
When it comes to good signals, then it is necessary to talk about the signal is not good, when the hand file to the back of the phone WiHD module, the TV screen will appear stalled, hands off the TV screen can be restored immediately and the current mobile phone screen synchronization No search process is required. The distance I test is about 3 meters away from the TV. As long as you don't block the WiHD module, the picture will be very good. However, if there is a large screen between the phone and the receiver, the screen will also There was a pause, and occasionally the screen continued to play, but occasionally there was a Karton mosaic, but this situation was rare, only a few captures were caught, so either normal play, when the signal was not good, the picture paused until Resume after signal recovery
The following picture shows a picture of Karon I captured. The general situation does not appear. This is when I put my phone on the coffee table.
In general, when placed on a coffee table, as long as the WiHD module is roughly in the direction of the TV, there is no need to deliberately align or put the back of the phone upside. There are a few mugs in front of the phone. However, we must not block WiHD when picking up the mobile phone. In fact, even if the horizontal screen game should not be pinched
to sum upAfter all, the 60GHz transmission speed, faster than 2.4G or 5G WiFi is not the slightest point, also because such a high frequency leads to poor penetration, the higher the frequency of poor penetration, 5G worse than 2.4G A lot. I don't know if this technology can develop in the future, or, like some other technologies or protocols, it won't end up. . .
advantage:
Small, business trip with a look at the hotel is also very cool
1080p resolution, and fast, it is said that also supports 3D, just TV also supports 3D, but have not tried, it is possible, as long as the left and right screen video source on it
The texture is very good, there is a small scientific and technological gadgets on the TV cabinet
Disadvantages:
The signal penetrability is poor, but this is unavoidable, after all, the high frequency of 60GHz
The price is too expensive. Today, the popularity of smart TV boxes, 499 probably no one will buy it. . .
Too small
This is a small-scale evaluation, and I hope that there are other value-friends can tell me that there are those Dongdong can be paired with this guy, after all, only the use of this cell phone is too narrow. thank you all
