[GoogleCast mirroring](https://commercial.screenbeam.com/en/support/known-issues-troubleshooting-tips?hsLang=en#googlecast-mirroring) # Google Slides Updates Slowly When Casting the Entire Screen This article applies to the ScreenBeam 1000 EDU Gen 2, FLEX, and 1100 Plus. When presenting Google Slides using Google Cast from Chrome, slide changes may take **3–5 seconds or longer** to appear on the ScreenBeam-connected display. The issue has been observed with ScreenBeam firmware **20.0, 20.x**, and earlier firmware versions may also be affected but have not been confirmed. The issue has been observed with **Chrome versions 152 and 154** when users: 1. Open a presentation on the Google Slides website. 2. Use Chrome’s Google Cast feature and select **Cast screen** to share the entire screen. 3. Start the slideshow and advance through the slides. The presentation may respond normally on the computer while slide changes appear several seconds later on the ScreenBeam-connected display. ### Recommended workaround Try either of the following options: 1. **Update Chrome to the latest version available for your device.** The issue was not observed with Chrome 157 in our testing. On Chromebooks, Chrome updates are delivered through ChromeOS updates. 2. **Cast the browser tab instead of the entire screen.** Open your presentation in Google Slides, open Chrome’s **Cast** menu, select **Sources → Cast tab**, and choose your ScreenBeam receiver. Casting a tab can reduce mirroring bandwidth use and provides greater privacy by sharing only the selected tab. Your desktop, other applications, and unrelated browser tabs remain outside the shared view, keeping the audience focused on the presentation. ### **Investigation status** The cause remains under investigation. Testing indicates that the behavior may depend on the Chrome browser version. Updating ScreenBeam firmware alone has not been confirmed to resolve this issue. If the delay continues with Chrome 157 or later, contact ScreenBeam Support and provide your ScreenBeam model, firmware version, Chrome version, operating system version, and whether you selected **Cast screen** or **Cast tab**. -
