The fix would be to make sure that the browser is updating the timer on strict 60 FPS intervals.įor the network section, we would like to try this again on a strong, stable network. However, this should still give us an idea where each product is at. Potential errors: The engineering team mentioned there could potentially be some rendering issues within the browser itself that could skew the results. The results are highlighted for visibility. To get the latency estimate we took the MacBook number minus the iPad number. If you look at the above Sheets document the two columns on the left of each highlighted column is the raw data (MacBook on the left column, iPad on the right).

To perform the test, we took 50 samples of each software and got the average latency from those samples. Results: You can find the test results here You can access all the files of the raw captures here: We had rather low quality but continued with the test as it’s representative of real-world use. The USB connection test is straightforward For Wifi, keep in mind that the network we tested on was a standard home network and the network wasn’t the greatest. So, in this case, we would take the result on the Mac (7069) and subtract the value on the iPad (7052) giving us 7069 – 7052 = 17ms, which tell us the iPad is 17ms behind the Mac or about 1 frame running at 60FPS. This gives a timing what the end-to-end latency is.
#DUET DISPLAY SOFTWARE PRO#
What we do is mirror the MacBook Pro screen to the iPad and then take a picture of both devices, then take the difference between the MacBook Pro number and the iPad number. Latency Testįor the latency test, we used this test page from AnyDesk. Duet Display (Mac: 2.0.4.6, iPad: 2.0.9)Īll software was configured to run at the highest quality setting when available, so that means 60FPS, highest quality unless otherwise noted.We made sure to run the latest version of the software, which included:
It is worth noting that throughout the entirety of the tests, the computer was always plugged into a charger and a Razer LanceHead Mouse. Experiment Setupįor this test, we used a 2017 MacBook Pro 13″ (MacOS 10.14.2) along with a 2018 iPad Pro 11” (iOS 12.1.1). In addition, we did a frame rate test to determine the maximum frame rate each product runs at. This report is meant to provide a baseline as to how our LIQUID v3 (that’s used in Astropad and Luna Display) latency compares with competitors like Duet Display and Air Display.
