Avatar + HDzero Compatible Goggles?

Are you an FPV enthusiast on the hunt for the best premium goggles on the market? Look no further! Chris Rosser, a well-respected name in the FPV community, has just released a highly-anticipated video comparison of the Walksnail Avatar goggles and the HDzero + Walksnail VRX unit. In this video, Chris puts these goggles to the test to see which one comes out on top in terms of latency, image quality, and overall performance. Get ready to be blown away as Chris unveils the results of this ultimate goggles showdown!

Testing Latency:

Chris wanted to put the HDZero goggles plus the Walksnail VRX up against the Walksnail Avatar goggles to see how they stack up in terms of latency. The systems were synchronized so that the LEDs turn on at zero, and the frames were captured at 1000 frames per second on a high-speed camera.


The Avatar goggles were the first to come in at 720p 100 frames per second, followed shortly after by the HDZero plus Walksnail VRX 100 frames per second. Then the Avatar goggles at 1080p 60 and finally the HDZero goggles plus the Walksnail VRX at 1080p 60. The results showed that the HDZero goggles plus the Walksnail VRX were slower than the Avatar goggles in both of these modes. This suggests that even though the HDZero goggles support the 720p 100 frames per second mode from the Walksnail VRX, they are not able to achieve the same latency as the Avatar goggles.

Comparing to the Sky04x goggles:

We also put the HDZero goggles up against the Sky04x goggles, both using the Walksnail VRX. At 720p, both the Sky04x and the HDZero goggles had almost identical time to first pixel latency, with the higher frame rate on the HDZero goggles giving it a faster time to full frame. However, at 1080p the Sky04x outperforms the HDZero goggles and delivers a slightly lower latency in both time to first pixel and time to first full frame.

Explanation of Latency:

From these tests, we can see that neither of the systems using the Walksnail VRX are as fast as the Avatar goggles. The extra latency varies, but it looks to be about an extra 10-12 milliseconds at 100 frames per second or about an extra 6 milliseconds at 60 frames per second. This additional latency is likely caused by the HDMI output stage of the Walksnail VRX, as it has to convert the video to HDMI.


It’s also worth noting that the advantage of 720p 100 frames per second is not as significant in terms of latency compared to 720p at 60 frames per second, with the difference being around 5-6 milliseconds. Furthermore, the Sky04x goggles perform better in terms of latency at 60 frames per second than the HDZero goggles. However, this is something that HDZero is working to improve and we should expect a firmware build in the near future that will optimize the HDMI input lag for 60 frames per second. In conclusion, while the HDZero goggles plus the Walksnail VRX may not be able to achieve the same latency as the Avatar goggles, they are still a versatile and high-performing option for FPV enthusiasts looking for premium goggles.
