To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
NOTE: This is an updated review after testing the device in more detail.
I have a Chromecast, an Amazon TV Fire Stick and this. For the ones who are wondering (I had the same questions before I bought them), although there are similarities, all these products have significant differences due to their underlying technology standards. You will hear of terms such as Miracast, WiDi, etc., and it may be useful to check if the devices you want to use it with (laptop, tablets, smartphones) are compatible. For example, relatively old versions of Android phones and Windows laptops that do not possess the correct hardware/software may not work but usually would have to be more than 3-5 years old. Also, entry levels smartphones such as the Samsung Galaxy J5 (2016) won't work with it so it is advisable to check online if it works.
What this device does (and quite well), is to transmit the image and sound from supported devices to a monitor/TV. It is basically a "wireless HDMI cable". It works by default in Windows 10, if using earlier versions you may need some Intel software. Both the USB port on my monitor and TV were enough to power it. Even thought the USB port on my relatively old LG TV was a "service" port, it still worked. If you don't have a USB port nearby you can use your phone USB charger if it has a USB A port.
Setup wasn't that complicated. Strongly suggest using a Windows 10 laptop for the initial setup and downloading the Wireless Display Adapter app from the store. After connecting to the device, check for firmware upgrades and upgrade the firmware.
To connect to it using Windows 10, use the Connect icon on the Action Centre in the taskbar.
Funny and true story...when I first tested it (very briefly) I was able to get image and sound from my "fantastic" Dell Monitor using my laptop. A few days later I tried to mirror my Galaxy S4 screen to the same monitor but no sound. Then I went on to do something else and later discovered the sound on the monitor was super low (not mute), so I tought I need to try phone again. A few weeks later, tried phone again, same issue. Then a light switched on my brain, checked and the sound on the monitor was super low again. So I asked my girlfriend if she turns the volume down when she uses my monitor to study. I think you already know the answer!
So if sound is not working, check for things like volume on both devices, update firmware, check with your partner :)
So why the 4 stars instead of 5: On the good side, the device in my opinion is very good and high quality, the mirroring from my S4 was fantastic and lag free, slightly better than the Chromecast! It does not have a dedicated USB power adapter which means easier to transport and seems to require minimum power because it worked well in my "old" TV USB service port. Great as a quick cable free solution from my laptop which I use a lot for work as an extended screen. As the image is transmitted directly, no need to connect to Wi-Fi network like the Chromecast, it feels faster and works much better with laptops.
On the not so good side, I don't think the original price is worth the money, but when the price was halved it was a different story. On 2 different laptops, I noticed a bit more lag than I expected (I read lot of people have different lag experiences) but the latest firmware seems to have improved it a bit. I also noticed a bit of blur (no it's not the resolution, nor the monitor, same on TV). I have a Dell UltraSharp monitor! For example the text on the Windows menus seems to be missing a few bits. On closer inspection seems to be a refresh/frame rate issue. A bit of reading confirmed that it may be a limitation of the technology. There may be workarounds (or not) but I haven't explored this further. If you use it mainly for work it's not an issue but if for gaming or movies you may be slightly disappointed. In extended mode, sometimes when transitioning from monitor to laptop it's like the mouse cursor hits a wall, I have to move it to the other side and then try again. As the USB cable is short (I haven't required it to be long yet), it would have been nice to have an USB extension included in the box, since it does not have a USB power supply and other similar device that are cheaper offer one.
Unlike the Chromecast, Roku's and Amazon Fire TV Stick this is not a media player/streaming device but I believe it has its usefulness.
Eine unproblematische und einfache drahtlose Bildübertragung zum Beamer hatte ich gesucht, und der Display-Adapter erfüllt das eigentlich auch sehr vorbildlich: einfach in den HDMI- und USB-Eingang gesteckt, in Windows 10 mit Windows-Taste+P und "Mit drahtloser Anzeige verbinden" ausgewählt, und zack, ist das Bild da. Einfacher geht's nicht. Es gibt eine minimale Verzögerung, die aber überhaupt nicht stört. Für Präsentationen, Diashows und ähnliches ist es also super geeignet.
ABER: Sobald man Filme oder Videos darüber übertragen möchte, kommt es zu minimalen Bildrucklern. Sie sind nicht besonders stark ausgeprägt und beim flüchtigen Hinsehen wird man sie wohl kaum wahrnehmen, aber schaut man sich einen Film an, in dem sich etwas bewegt, dann fällt einem sofort auf, dass da irgendwas komisch ist.
Die bisher im Netz kursierenden Notlösungen dafür sind entweder den USB-Stecker des Adapters an eine Quelle mit höherer Spannung anzuschließen, die Bildwiederholrate zu ändern, die neueste Firmware aufzuspielen und/oder das übertragene Bild nicht als duplizierte oder erweiterte Anzeige sondern als alleinige Anzeige zu nutzen.
Alles ausprobiert, nichts bringt Abhilfe, weder an einem normalen Laptop noch an meinem Surface. Super schade, denn wenn das Problem nicht wäre (und es besteht wohl schon seit der ersten Version des Adapters und bisher gibt es keine zufriedenstellende Lösung dafür) dann hätte ich ihn definitiv behalten.
It worked out of the box at home on my Windows 10 laptop. However I bought it for my Windows 10 laptop given to me by my employer and for that it didn’t work. It turns out that my laptop uses Cisco AnyConnect VPN which is typically set up at the kernel level to disable the Miracast protocol that the Windows Display Adapter uses to connect your PC/laptop to a monitor. That is a semi-technical explanation and may sound like gobbledygook to most of us, including me before I did a day’s worth of reading. However, my summary is to be very, very careful before buying. If you use a work PC/laptop or you use VPN (I.e if you need to type in a SecureID code to access your systems) check that the display adapter supports your VPN software by scouring the Microsoft website first.
Aufbau: -> Bild und Ton werden über einen 5x HDMI-Switch an einem Sony Full-HD TV-Gerät ausgegeben. -> Energie bezieht der Miracast-Adapter über einen USB-Port des besagten TV-Geräts.* -> Über Miracast angebunden sind ein 2017'er Surface Pro, ein HP Elite X3 und ein Sony Tablet Z1 (Sony nennt Miracast hier Throw).
Alle Geräte bauten im bereits ersten Versuch ohne zu Murren eine dauerhafte und stabile Verbindung auf und auch die weiteren Verbindungen waren ohne Beanstandung. Hierbei fiel mir negativ auf, dass es beim ersten Verbindungsversuch keine Sicherheitsabfrage gibt. Ferner ist das Gerät wenigstens 1x doch recht warm geworden. Die "App" aus dem MS-Store ist übersichtlich gestaltet und wird für den eigentlichen Betrieb nicht benötigt, wohl aber für Firmwareupdates und (Sicherheits)-Einstellungen.
*Jene, die über Abbrüche und/oder Aussetzer klagen sollten hier ggf. eine andere Energiequelle wie z.B. ein USB-Netzteil ausprobieren.
P/N/K: +: Kompakte Gerätegröße. +: USB-Verlängerungskabel. o: Kann recht warm werden. o: Typisch Microsoft recht hoher Preis. -: In der Grundeinstellung keine Sicherheitsabfrage beim ersten Verbindungsaufbau.
Eine Randnotiz: Auch wenn es vom Standard her wohl möglich sein soll, so konnte ich, unabhängig von diesem Adapter hier, kein mit einem Kopierschutz versehenes AV-Material (z.B. Netflix Streaming) über Miracast übertragen werden
Transmits video over WiFi Direct (does not require an intermediate router) to your TV or projector. I use mine to transmit a full quality (no apparent compression) screen image from my Samsung Galaxy tablet to my projector. You require both an HDMI port and a USB B (for power) type socket on your display device, and obviously WiFi on your computer/tablet. Both my devices use WUXGA (1920x1200) resolution so it works properly up to those resolutions at least.
My TV unfortunately doesn't have Wireless Display capabilities, but it does have USB and HDMI ports, so just by connecting and configuring this adapter (which is easy to do), you can have wireless streaming from your PC to your TV or monitor. If you use Windows you can easily extend or duplicate your PC screen or just project to the second screen from the Operating System which is nice. The reason I'm giving 3 stars is because unfortunately the connection is not robust and it doesn't last for more than 20 min without me having to manually reconnect it again. Also although the range of the connection is quite reasonable (sometimes I stream from my Surface Pro 4 to my TV almost 3 meters away), the transmission stops if you move the computer or streaming device too much. For such an expensive adapter I would expect much more quality, this rather resembles a prototype and not a seriously tested product.
I brought this to extend my laptop display to my monitor to save me using a hdmi cable, and this device doesn't work very well for that purpose.
To begin with I was surprised how easy it was to set up and get connected to. It's pretty much plug and play, just stick the hdmi in the display, and plug the USB in (I used an external adapter as the minister lacks usb ports).
Once connected to the laptop I found the picture quality good enough, but not perfect with the occasional artifact and only slight input lag with the mouse. But after using it for a while I noticed two major problems that makes the device no good for what I want to use it for.
Firstly on my laptop I use a Bluetooth mouse, and I found the connection to the display works perfectly fine if you move the mouse around slowly, but if you start being slightly erratic with the mouse it caused the image on the wireless display to have connection problems and jitter. This itself is slightly annoying, but can be worked around.
This second problem is that deal breaker for me though. Using the wireless display caused the CPU usage on my laptop to be way higher than it would be if I just used a hdmi cable. Just watching a YouTube video on the second screen with the adapter had my CPU usage at around 50%, which is way higher than the normal 10% and less you get when using hdmi in the same situation. This means that using the display my laptop would both get hotter than it needs to (not good during the summer months), and also drain the battery way quicker than normal.
Because of these two problem I've very quickly given up on using the device in the way I intended to use it. Thankfully though it works well at mirroring my phone display, so I can use it or doing that.
So in short; not good for extending a PC display, good enough for watching videos on a larger screen without any multitasking.
Firstly, for those that may be unaware of what the Microsoft Wireless Display Adaptor is. It essentially turns your second screen into an extended desktop but wirelessly.
It uses the Miracast 'standard' but don't let this put you off! Miracast has had a bad press and for good reason over the past few years as the idea never seemed to meet expectations until now! Before this gem of a device came along, Miracast performance was largely dependent on hardware compatibility and performance at both source (PC/device) and the second screen (TV/Projector/monitor). It was hard to get devices to 'play' well together and thus Miracast tends to be very unreliable and often useless due to extreme lag.
Microsoft have addressed this by producing it's 2nd version of this Wireless Display Adaptor to essentially bridge the gap of the performance issues of the other kit your using!
It is once piece dongle with HDMI one end and a USB on the other. When not in use, they plug neatly into a little plastic housing for easy storage.
To use: 1. Simply plug the HDMI and USB plugs into the 'second screen' that you wish to use. 2. Go to your PC/Phone/Tablet and connect via your device 'Screen Mirroring' setting. 3. Click/press 'MSDisplayAdapter' and that's it, simple!
There is no noticeable lag or delay although, in use, I have noticed a slight slow down from time to time but not enough to bother me. Just disconnect and reconnect and all is well. Microsoft do not market this device for use with gaming BUT I have tested and noticed around 0.5 sec delay (at it's worst), so not at all bad really. It would be fine for video sharing/viewing. Audio is also shared and automatically mutes the PC.
To summarise, this device is superb for office-based second screen sharing use and presentations and if using with Windows 10; behaves in the same way as if you had a second monitor plugged into your PC and with all the same options (duplicate, extend and second screen). The fact that it handles video/audio well is a bonus. I have used similar devices at twice the cost but offer only mediocre performance. This device is far superior in my experienced opinion.
Bought this to replace my Netgear Miracst device, which was awesome, but sadly the USB connection was becoming a little dodgy through heavy use. This Microsoft Wireless adapter is the perfect replacement, exceeding all expectations. I guess it should work well as I use it with my Microsoft Surface Pro 4, and thus both being Microsoft should work well together. I have also used it with a Samsung phone and also worked well. Video is almost perfect with rarely any stutter and for normal presentation work, nigh on perfect. It is also neat and compact and simple to set up. Unlike a number of similar devices it does not require to be connected to your wireless network, so is completely transportable, enabling me to connect to any TV or projector via an HDMI slot and powering off any available USB slot or via an adapter. Sadly the only time it wont work is through a HDMI cat5/6 Video sender, but I can live with that. After all I don't always need to project wirelessly, just like the freedom it gives me when doing presentations, and it looks very professional when I do.
Wanted this to mirror the screens of two tablets to a TV which had HDMI but no USB. Planned to use a separate USB power supply plug to power the device. The tablets I wanted to mirror are both Samsung. One is Android 4.4 Android 9. I wanted to use the device to mirror movies.
Plugged the dongle into the HDMI port of the TV and connected it to a separate USB power plug made by a leading manufacturer. The device powered up and displayed the Microsoft landing page but was unstable. Both tablets were unable to find/see the dongle. At the time I was about one metre away from the dongle.
I concluded that it might be a power supply issue. I change the power supply plug over and the device worked perfectly with both tablets. Video streamed okay with no jitter in sound or vision.
Checking out the PSU plugs I saw that both were rated at 5v 1 amp. My only thought is that the first PSU I used was not 100% spec for USB voltage. Which leads me to conclude that the device may need a good strong USB voltage. If the USB voltage is slightly off then there could be problems with it working.
Other than this the device does what is should do. It works with Android 4.4 and Android 9. and streams video okay. I am happy with it except it does seem to be overpriced.
