We did have a slight issue with our laptop screen automatically adjusting its own resolution, but it was nothing a quick display setting change couldn't fix. When connected, the Warpia system allows you either mirror or extend your current screen to an HDTV. All of these settings are easily accessible via the system tray icon that's installed during the initial one-time setup.
Performance-wise, we were extremely happy with the results of wirelessly transmitting our laptop's screen. Our Panasonic HDTV had no issues accepting the 1,280x960-pixel signal using the HDMI-out on the receiving base.
For an even higher resolution, there's the option to use the SXVGA+ port that can support up to 1,400x1,050 pixels. Keep in mind, though, that not all HDTVs accept this type of interface connection, so odds are that HDMI will be the way to go. Warpia says the system can support up to 720p HD streaming video; anything higher will drop frames and lag as our testing confirmed.
As for mouse-to-screen time, there is a tiny bit of a noticeable lag, so we can't recommend using the system for gaming or any application where real-time movement is a must.
The Warpia system is also a bit sensitive when it comes to blocking line of sight between the transmitter and receiver. We noticed a bit of a signal drop when placing multiple obstructions in between the two, but for normal use we don't think it will be too much of an issue. That said, don't expect the Warpia to work through walls and floors, as there needs to be very little in between the two devices. The Warpia performed well in our 25x25-foot testing room, but it struggled the second we left it.
In terms of audio, we had no problem using the audio over HDMI and the separate 1/8-inch jack on the rear of the receiver. Furthermore, we didn't notice a difference in quality regardless of which interface we used.
Though the company does not advertise the PC-to-TV system as being able to do so, there is some hope for Mac users out there. Using a few beta drivers and software hosted on the company's site, we were successfully able to wirelessly stream our MacBook Pro to our HDTV. Keep in mind that this is not officially supported by Warpia, so any issues with using the technology may not be easily resolved. Regardless, we're happy to see the Mac support here.
Our only qualm with Mac performance was full-screen video. It seems the system has an easier time streaming full-screen video from a PC than it does with a Mac. We had some success with dragging a video player to take up the entire screen, but once in full-screen mode, the video began to get choppy.
Overall, we were impressed with the Warpia system. For around $160, it's certainly not cheaper than running a few wires directly to your HDTV, but for those in need of such a wireless luxury, we're not sure there's an easier way to get audio and video from your laptop to your big screen.
