Hello there, Joseph. Thank you for reaching out about your LG 39GX90SA‑W UltraGear OLED monitor. We understand your situation and are happy to explain the in‑store demo setup. In our retail locations, the monitor runs a proprietary UltraGear OLED Showcase Demo Loop when put into Store Mode. Internally, this demo is labeled as “StoreMode_Demo.mp4” in the webOS Samples section, but it’s not distributed for end‑user download. The loop highlights key features—gaming footage at 240 Hz, HDR scenes, and webOS app previews. Here’s one helpful troubleshooting step if you’d like to view or verify the demo content yourself: Enter Store Mode on your monitor: Press the joystick, go to Settings → All Settings → General → Support → Home/Store Mode, and select Store Mode. Open the Media Player app from the home screen. Navigate to Samples → Store Mode Only. You’ll see StoreMode_Demo.mp4 listed—select it to play the same loop you see in stores. If the file doesn’t appear, please make sure your monitor’s firmware is up to date by visiting the Support & Downloads section on LG.com and installing the latest webOS update. That will restore the full Store Mode demo package. https://www.lg.com/us/monitors/lg-39gx90sa-w-gaming-monitor#pdp_specs We’re here to help with any further questions or setup tips.
