I received my much-anticipated Looking Glass display only a day ago. Sadly, I have been unable to advance past the Holo Play Test App. I am among the users afflicted with the Garbled Display. I triple-checked the Standard Looking Glass Setup Guide as well as the Troubleshoting Section of The Looking Glass Factory Wiki and combed the Support and Troubleshooting Forum Category for people experiencing similar issues and read them thoroughly. I was only able to find one that fit well, but there are still significant differences in our cases.

While my Garbled Display is the same in appearance, I have an older machine compatible with the provided cables.
Unlike user rzsombor, I have an older MacBook Pro (System Info Below) compatible with the provided cables.
Like user rzsombor, when I opened the test app, the display was garbled and accompanied by a series of zeroes. The support staff suggested that this meant the calibration data was not being read.
It is worth noting that these results did not change with subsequent testing.
I also tried opening the Library app to help diagnose the problem and got an error message that read “No calibration data from Looking Glass”
As per the error message and the solutions recommended in user rzsombor’s support thread I tried both a regular reboot, and a hard reboot without detaching the Looking Glass display.
When I had the library app open, I noticed that the image was not as garbled as the one in the test app, rather it had multiple diagonal slices. each slice seemed to be showing the full range of view, so in some of the previews there was what looked like a curvilinear display as well. Out of curiosity I played with the Underscanning options in the display preferences, this tightened the number of diagonal shears. It looked like I would be able to correct the issue entirely if I could set the slider to a value less than zero, or rather, if I could get the operating system to overscan rather than underscan.
The first image, featuring The Looking Glass Factory logo best demonstrates the diagonal shears, the second and third images best demonstrate the curvilinear distortions.
Unfortunately I do not own any other USB-C Devices, so I have not been able to test if the problem lies with the included cable. I doubt this, as the display shows an image, and ceases to function when either cable is unplugged from either end.
It is also worth noting that while three of the buttons are not functioning for me, the square button, on the far left is, and is functioning as a click, wherever my cursor happens to be.
I can still think of one or two more things to try on my end. If my efforts bear fruit, I’ll update the thread.
