The following is a guest post from the home electronics and gaming blog, The Generalist:
I picked up the HP Wireless TV Connect because I was looking for an easier way to play games and watch streamed videos on the television in my bedroom. Since my HP Envy 17 3D has a full size keyboard and a decent built in microphone my thinking is that I can play games with the laptop still on my lap, but with the video on the TV. I’m happy to say that the device works really well for me. Setup was easy, there’s no noticeable latency, and the video quality is decent.
Setting up the device was very easy. The TV side box has a picture of a TV on it and the laptop side has a picture of a computer. The TV box has one HDMI port to plug into an HDMI port on your TV and one power adapter to plug into the wall. The laptop box has one HDMI port to plug into your laptop’s HDMI and one USB port to plug into a USB port on your laptop for power. All the needed cables are included and are color coded to match the ports on the boxes. No drivers are needed. I plugged both boxes in and switched my TV to the correct input. The image automatically switched to the TV. Depending on your laptop, you might need to press Windows Key + P until you switch to projector mode (for Windows). You might also need to shrink your screen to fit your TV. I had already done this with a physical cable in the past, and the setting stayed when switching to the HP Wireless TV Connect. The laptop doesn’t know this isn’t just a HDMI cable. The audio started playing on the TV as well. The laptop side has an optional cradle I used to hold the box on the back of the monitor screen. This worked well keeping the box out of the way for me.
I didn’t notice any latency while using the device. HP claims that there is less than 1ms latency and I believe it. Playing TF2 I couldn’t feel any of the rubber banding or delays that you sometimes get with wireless devices. The TV could have been connected with a physical cable as far as I could tell latency-wise. This was the most important feature for me and HP delivered. I had considered using Intel Wireless Display since my laptop supports it without the need for an external box, but that technology introduces latency which isn’t good for gaming. The HP Wireless TV Connect is the way to go if you want wireless HDMI for gaming.
The picture quality is good, but not perfect. To send the image wirelessly and quickly, a lossy compression is used. If you look closely you can see the artifacts of that compression. I did have to watch for it to see it though. While playing a game I didn’t see it. Between the movement and the distraction of the game I just don’t notice. The one exception I had to this was text in certain places wouldn’t be crisp. This is probably a combination of the scaling to the monitor and the compression of the device. For instance, you could see the artifacting in TF2 in the notification text in the lower left corner. The text was still legible, you could just tell that it wasn’t perfect. On the Windows desktop, MS Word documents look good, and the text is pretty clear, but not perfect. Some spots (for instance the borders of the Steam interface had more obvious issues, but nothing that made them unusable. As I said, the image is good. I’m very happy with this device. I just wanted to clarify that there is a bit of quality loss.
