Watch HD video without wires
I wanted to connect the HD panel to the computer with a second monitor at home to be able to watch movies and play games on the big screen. But there is a problem - the TV and the computer are in different rooms. And I didn’t want to drill the wall and pull the HDMI at all, the diameter of the hole in the wall would be rather big.
And so, I decided to order on ebee this is a Chinese miracle. Meet EDUP Wireless HDMI 1080p
Official device specifications are as follows:
Supported video formats: TV 1080p, 1080i, 720p, 576p, 480p, PC: VGA (640x480), SVGA (800x600), XGA (1024x768), SXGA (1280x1024)
Audio formats: PCM, DTS, DOLBY DIGITAL
Maximum transmitter power: 12dBm
Maximum working distance: 20m in open space, 10m indoors (may vary depending on wall thickness)
Delay pictures: <1ms
Frequency: 5.1GHz - 5.9GHz
Modulation frequency for IR transmitter: 38KHz
Voltage: AC In 100 ~ 240V, DC Out 5V
Work temperature: 0 ℃ - 40 ℃
')
It all works according to the WHDI standard .
The price of my kit with delivery was 177 dollars . Delivery from China to Ukraine took exactly 9 days.
We can find the name CrystalMedia Wireless 5G for about the same price. (I found out about it only when I disassembled the device and google the name printed on the board)
Box with device
complete with receiver and transmitter
Two power supplies, HDMI cord, IR transmitter (can be connected to the receiver and sent to the media player to control it from the copper player's remote control) and the remote control. The control panel is useful only if you want to connect several transmitters to the receiver.
The receiver and transmitter are almost the same, the main difference is in the labels near the HDMI connector (HDMI IN and HDMI OUT).
At the front end you can see the power indicator and the connection indicator.
The signal strength is displayed at the time of connection on the screen of the device connected to the receiver.
At my house at a distance of 3 meters and the wall shows the maximum power.
The device promises to transmit uncompressed video stream with a delay of less than a millisecond. On the Internet I found a couple of disgruntled reviews that the device compresses the video and spoils the picture. I did not manage to see it on my Philips 32PFL4606H TV (it has an IPS matrix).
Sometimes I play Far Cry 3 and STALKER, the delay is really very small, it does not interfere with play. For games I use a wireless mouse and keyboard from Logitech.
But when testing the device on a monitor with a resolution of 1600 * 1050 there was a big problem.
An obvious flaw in the firmware. If you transfer a picture with a resolution of less than 1280 * 1024, the green bar disappears. With the TV and monitor Full HD 1920 * 1080 such problems did not arise.
