			=== Resident PC input flickering ===
			In October, 2019, the screens began flickering when displaying the resident PC input. The side screens and the confidence monitor would go black for a fraction of a second. The flicker was synchronized on all three screens. The tech station screen was never tested. The projector would experience a different artifact. Instead of turning black, a horizontal line of color noise would appear across the top third of the screen. This occurred out of sync with the other screens. The issue did not occur immediately upon powering on the devices. It would also get incrementally more frequent. This implies that the issue may be heat-related. [[Rod]] was the source device. The effect was never confirmed with [[Todd]], nor with the laptop input. That semester, [[Hans-Helmut Kotz]] was giving two lectures per week, using projection every time. He reported no issues.

			[[Peter Stevens]] submitted a ticket to AdTech. [[April Roland]] created the ticket and [[Robert O'Shea]] troubleshot the issue on October 24. [[Michael Berrio]], Stevens, and O'Shea could not replicate the issue. O'Shea was highly confident the issue was an input issue. He said the screens and the projector were probably handling lost signal differently, causing the different effects. O'Shea noted that the output resolution on Rod was lower than 1080p, but the input signal on the Crestron was 1080p. The input chain consists of Rod's software, Rod's HDMI output, HDMI cable, Crestron transmitter, CAT cable, and the Crestron input card. They arrived at the following solution: replace the HDMI cable. If the issue reoccurs, swap out Rod for Todd. If the issue reoccurs, call AdTech to inspect the transmitter, CAT cable, and input card. The devices which may generate heat are the transmitter and the input card.
