Part 3: Show Me the Button
Lydia did not raise her voice when she said it. She set the tablet against her hip and looked at the wall-mounted screen first, then the laptop on the cart, then the remote in Sharon’s hand.
“Show me the display-chain stability issue,” she said again.
Sharon gave a short breath through her nose. “It is not a visible fault every second. It is a procedural miss.”
Lydia nodded once like she had heard the words and was setting them aside. “Then show me the procedure on this room’s equipment.”
Nobody in the room moved. The session slide was still up behind Sharon, white text on blue, clean edges, no overlay. Evan stood close enough to see both the laptop and the screen. I stayed by the HDMI cable and the cart.
Sharon lifted the remote. “The problem happens when the announcement memory is not cleared before source takeover.”
Lydia said, “What control clears it?”
Sharon pointed the remote at the screen, then lowered it again. “It is sequence-based.”
“Walk the sequence,” Lydia said.
That was it. No speech. No warning. Just the plain instruction.
Sharon pressed the home button. The slide deck disappeared and the screen went to the display’s input menu. Big square icons came up for HDMI 1, HDMI 2, wireless cast, and the center’s internal signage app. She tapped over to the signage app and opened it. The rotating center announcements came back: swim hours, a blood drive flyer, next week’s room closures. The graphics rolled across the screen exactly the way they always did.
“This is the public layer,” Sharon said.
Lydia watched the screen. “All right.”
Sharon clicked back out to the input menu and returned to HDMI 2. Her volunteer slide came back full screen. “If source is pushed before stability bleed, announcement residue can remain in the chain.”
We all looked at the slide.
Nothing remained.
Sharon pressed mute, then unmute, then source again. She opened the menu, closed it, switched to HDMI 1 by mistake, got a black screen with no signal, switched back to HDMI 2, and the same volunteer slide returned. The lower third stayed empty. The corners stayed clean. No schedule band crawled underneath. No ghosting floated behind the text. It just looked like a normal slide deck on a normal display.
Evan said, “Is that the bleed?”
Sharon did not answer him. She stepped to the cart and used the laptop trackpad again. She opened the presentation view, clicked out of it, opened the display mirror settings, then the sound panel, then back to the slide deck. Her binder slipped against her side and she caught it with her elbow.
Lydia said, “What are you selecting right now?”
“I’m checking whether the unit retained the prior state,” Sharon said.
Lydia looked at the laptop screen. “What function are you calling stability bleed?”
Sharon’s hand stayed on the trackpad. “It does not necessarily appear under that label.”
Lydia said, “What label does it appear under on this system?”
The room held still around that question. I could hear the vent over the back row and the soft click of the laptop fan.
Sharon straightened up and gestured toward the wall display. “Again, these units share a display family. The process is standard even when naming varies.”
Evan said, “So which process did Nina skip?”
Sharon opened the signage app again. Another announcement card came up, then another. She switched back to HDMI 2. My slide deck returned exactly where it had been. No streaks. No residue. No hidden public layer. Just her bullet points about volunteer check-in.
Lydia held out her hand. “Remote.”
Sharon gave it to her after half a beat.
Lydia pointed the remote at the screen and moved through the same inputs more slowly. Signage app. Back to HDMI 2. Home. Back to signage. Back to HDMI 2. Then she looked at me.
“You said you connected HDMI, selected source two, and opened her file?”
“Yes,” I said.
“Any other step?”
“No.”
Lydia looked at Evan. “You were in here during setup?”
He nodded. “I saw her connect it and bring up the deck. That’s it.”
Lydia switched the screen one more time to the announcement app, let a schedule slide sit there for three seconds, then returned to HDMI 2. The presentation came back clean again. She lowered the remote.
“I don’t see a fault,” she said.
Sharon’s voice got tighter. “Because the issue is not always immediately reproducible. The risk is that she bypassed the stabilizing step.”
Lydia said, “Then identify the step on this equipment.”
Sharon looked at the screen, then at the remote in Lydia’s hand, then at the laptop. She said, “It is part of proper chain handling.”
Lydia waited.
Sharon said nothing else.
Lydia bent, picked up the printed room checklist from behind her tablet, and scanned down one section with her finger. Then she read out loud, plain and flat: “Display startup, source select, signage return after session. No stability step listed for this room.”
She looked back up at Sharon. “If you’re claiming an unlisted required procedure, I need the equipment reference now.”
Sharon’s mouth opened. No words came out.
Lydia tapped once on her tablet screen and said, “Stay here a minute. I’m opening an incident note on misuse accusation tied to shared equipment, and I need the names of everyone present.”
