Question: My Laptop does not have something called WiDi. Will this gadget work for me? I don't have Netflix and I just plant to see TV show's I missed.
Document: Also, if something passes between the dongle and the receiver, it loses connectivity. So even if you were in the same room and someone walked between the computer and television it would probably drop the signal. I was able to replicate this by waving my hand in front of the receiver while in the same room with a direct line of sight to the dongle. I called tech support and they said it's really only for use in board room meetings for hooking a laptop up to a projector or similar use. So, long story short, I guess I don't really see the point of this device, if you are only a couple feet away, why not just use an HDMI cable and save the hassle and connectivity issues?
The picture is great one of the things I don't like is it would drop the signal and you would have to unplug the power source and plug it in and it would go back working.I could not get it to transfer a dvd over to my hdtv I could get sound but no video.I called Diamond and they I had to upgrade my software for my player did t still doesn't work.I have plugged a Hdmi cable into computer to tv it worked fine.But all and in all it is a good product it works great Netflix you can't ask any better picture reproduction on screen.I just haven't figured out why it won't transfer the movie on dvd from my laptop to my tv set.
I purchased this to couple my Win 8.1 Laptop to to my TV. For this to work in Windows 8.1 you need to download their driver version 7.5 from their WEB site. Their instructions did not state this but when I contacted their tech support, they were very helpful. I can now watch Netflix and other streaming videos on my large screen TV. I had to use their VGA output as my TV has only analog &#34;component&#34; inputs. I used a VGA to component converter to interface my TV to this Adapter.
Prior to purchasing, I ask about the transmitting range of this unit and was told that it would go through wallboard interior walls but not a long distance. After receiving it and it did not work when the transmitter was on the other side of the wall from the receiver (less than 2 feet away), I called support and found out that it requires a direct line of sight between the transmitter and receiver. If they cannot see each other they are not going to work.
Works excellent for streaming web or Netflix from desktop CPU to our big screen TV. Glad I did my research for streaming devices!Update July 2013:  transmitter quit working one day and I called their CS for warranty help. They are quite busy and was hard to reach initially. Finally got a shipping label after a second call. Unit was sent to them for repair/replacement. Received it back in a couple weeks time but have noticed that this one doesn't seem to stream as quickly or as smooth as original. Pretty sure it is the transmitter which I believe is getting hotter than it should.
I've got a windows 8 laptop with specs reasonably well above the minimum requirements for this device. I bought it to play movies on the TV. When I first tried this it didn't work at all as it went slow and the sound was fuzzy. I instead routed the sound through separate speakers. This definitely improved the quality. Sometimes it will work fine, but more often it will be jumpy and poor quality.I'd shop around before getting this and see what other alternatives there are.
At work I needed something to hook up my laptop to the lcd projector. This works great. It's like having an extra monitor just for my students.
When I set it up, I could see the screensaver page of my laptop on the TV, but nothing else. Then I disconnected it and connected my laptop to my TV with an HDMI cable as I had been doing before, but this no longer worked. It messed up my laptop. Wish I had never bought it.
The installation instructions are minimal (you DO NOT need to install the drivers if you have Windows 7, BTW), and when we installed it we had video but no audio. After fiddling with it, trying it with different cables, checking the reviews in this web site and the Diamond topic boards, and going back and forth with tech support for two weeks, I finally called them - the device doesn't work with our Sharp Aquos TV. Call them FIRST before you buy this to make sure it works with your TV.Update later today:  In looking at our TV we saw that we could use the RBG jack/speaker jack input on our TV with the RGB/speaker jack outputs on the box.
I am using this on an older HP Pavilion Vista laptop with an Intel Duo processor that I upgraded to Windows 8. I am currently running Windows 8.1 Preview. Being one do fly by the seat of the pants installations I ran into one minor little snag which was quickly resolved by loading the most current software from their website.I am currently using with a Sony Bravia TV. Although not really necessary to use my laptop with this TV to watch the Amazon Prime Instant Videos I had to try it just to see if it worked.
Answer: Hi. You don't need widi. Just hdmi on your tv and USB on you laptop.  This thing works pretty good but does not have the greatest range.  You need to be in line with the receiver antena.
