Tests work fine in regular Chrome.

Fails with 500 error on http://localhost:5578/test?magicPattern=8a36052d02c5645bb97fc46e

Failed to find test pattern on screen. Ensure that your browser's zoom level is set to "100%", and the top-left corner of the window is visible. If you have multiple displays, try moving the browser window to the main display.

Single built-in display. I made sure browser zoom level was set to 100% and the top-left corner is visible.

Need to test setups with the secondary monitor to the left of the main monitor.

Screenshot APIs need investigation. When the Oculus SDK for Android is released, the Oculus Latency Tester can be supported as well.

I found that this only runs in 64 bit linux. I have a local set of changes where I remove oculus and cross compile to 32 bit. Will probably have additional changes as I look into making this work on windows.

It appears that IE and Chrome don't receive the scroll events sent by the test unless their window is manually clicked. Firefox doesn't have this problem.

Where is the ChromeOS download?

On Windows we only screenshot one monitor at a time. The screenshot API should be extended to allow choosing which monitor to screenshot and we should check all monitors when searching for the browser.

We'll have to dump GYP though. Could use CMake but I might look into building a standalone version of Chrome's gn instead.

The DXGI desktop duplication API requires manually rotating the image if the monitor is rotated.

The score is confusing because higher is better, despite all of the individual measurements being "lower is better". All of the results should be explicitly labeled.
