This product probably works just fine for some, but in my case there was a compatibility issue with my Harmony Elite universal remote which works in conjunction with a 2.4 GHZ WIFI based Harmony Hub. It caused my whole system to freeze. I ended up having to run a 50 ft HDMI through my attic. It might have worked if I switched my wireless router over to 5GHZ but in my case, it wasn't worth the hassle of reprogramming everything.

Okay but, Just upgraded my computer software to Windows 10, worked okay at first. Microsoft did a mandatory update to my Windows 10, something they call "Windows 10 Anniversary" and now my WPCTVPRO doesn't work. I called Diamond Multimedia and they told my that their WPCTVPRO doesn't work with Windows 10 Anniversary, because Microsoft did away with the Samsung Drivers, and as of this date (4-11-2017) Diamond has no answer.

UPDATE - A handful of months later (if you have 6 fingers) and there is still no W10 upgrade available. They have failed to reply to my email requests three separate times and, looking would the web, they do not intend to offer a fix! Stay away at all costs!

At the time of writing this product does not work with Win 10 Anniversary edition. There is no mention of this in the description.
The website suggests you roll back your Win 10.... much too late for most people.
I have written twice to the manufacturer and not received any reply.

If you buy this, you may have a very expensive "door wedge"...

I was able to get this product to work, but it had a hard time streaming Audio and Video at the same time. Distance was only 6-8 ft, so I did not expect any issues.

Great: if you are only presenting a Power Point, from 1 PC
Terrible: If you want to use it for streaming Wireless HD Video and Audio

If anyone wants to use this, they will need to install the SW. I did this, and the first time it worked. Two days later, I tried to connect, and it did not recognize it. I tried to reinstall the SW, and I could never get it to work again. Not sure what the deal is.

If you want to use this, for an office environment, where everyone can use it to present on your ceiling mounted projector... forget about it... Everyone would need to load SW and make sure it works on their PC... then you would have to change the Dongle out and worry about losing it.

If you have one PC to one TV and or Projector, and you are not planning on streaming video.. this is a great product for you.

Comapny took the return with no issues - so you can try it for your application and run with it.

I bought this for use with a teleprompter setup and it works like a charm! My teleprompter system consists of a PC with prompter software, a mirrored prompter (just like you see in TV studios) with a flat-screen monitor underneath and facing up to reflect into the angled mirror and, previous to this Diamond WPCTVPRO, a very long VGA cable connecting the PC output to the prompter monitor input.

Wow! Defines my satisfaction with this Diamond device. It has eliminated a tripping hazard that I had with the VGA cable and made everything involved a little more convenient. I've had the "transmitter" dongle/PC at least 30 feet away with no problems in reception of the "receiver" connected to the prompter monitor. I'm using the VGA output of the WPCTVPRO receiver for the monitor (which is a cheap, old 15" LCD that only has a VGA input). For s&g's I've also tried the receiver using its HDMI output with another monitor - no problems; excellent picture quality and reception. I've had people walk between the "line-of-sight" transmission and there's not been one hiccup, nothing! I've trucked and dollied the teleprompter camera while the WPCTVPRO was operating -- no reception problems. It appears to be a very strong signal.

The product comes with a small pamphlet that explains installation -sort of (there's more detail on the mfg website: (...)), and it comes with a mini-CD for installing the drivers. I didn't use it because the pamphlet indicated it was best to let Windows (7) download the drivers on its own. The pamphlet's instructions were a bit confusing in that it said for Windows 7 installation to plug the USB dongle into the PC USB port first, then d/l the drivers. Immediately after the d/l instructions it said to *not* plug the USB dongle in yet. Well, heck, I'd already had it plugged-in and d/l'd the drivers so I figured I was screwed. Not. I guess it didn't matter. Everything worked just fine.

There's a Windows taskbar icon for the WPCTVPRO program. Once you have the dongle plugged-in (is has a little blue LED "on" light, as does the receiver - flashing= no signal, steady=receiving) the taskbar icon is functional. Clicking on it provides a menu of functions including PC display settings [video] that is redundant with the Windows display settings (dunno why others here don't mention it) plus an [audio] setup as well. It also has a menu of WPCTVPRO options for the output. This taskbar icon menu has (imho) everything needed to make the system work for me.
Again, its wireless capabilities (and really, why else would I or you buy it?) are flawless. I'm not kidding, and this is not a planted review. I can only guess that the hardware and software have been significantly improved over time since some of the negative reviews here (although some are more recent). I've also allowed the system to stay powered-up for 24 hours to 1) See if it failed, and 2) See if either component got too warm/hot. Well, no failure and the dongle did get slightly warm, but nothing alarming.

That's it. 10-4, over & out.
