Hi Harry 0, Thank you for your feedback. For optimal performance, please ensure your TV is running the latest firmware. You can check this by going to: Home > left directional key > Settings > Support > Software Update To further optimize performance, try running Device Care, which checks memory, clears unused cached data, and closes background apps: Home > left directional key > Settings > Support > Device Care > Start Device Care. If this firmware version is not yet available on your TV, you can download the update on a USB drive and manually update your TV: 1. On Samsung's website (upper right corner), go to: Support > Manual & Software > Find your TV model, and click on the Firmware – Upgrade File. 2. When the file has finished downloading, locate it and then unzip it. There is normally one folder inside but there may be multiple files. 3. Copy or move all of the files that were included in the zip file to a USB flash drive, but do not place them inside any other folders. If you place the software folders inside a folder on the USB flash drive, the TV or monitor will not find them. 4. Connect the USB drive containing the software upgrade into a USB port on your device. 5. Using your device's remote, navigate to and select Settings, then select All Settings, and then select Support. Select Software Update, select Update Now, and then select Yes if prompted. Your device will search the USB drive for update files. Follow the on-screen instructions to install the updated software. Updates usually take a few minutes; please do not turn off the TV until the update is complete. When the update is finished, it will restart automatically. If you're still noticing performance snags after these steps, please contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). You can also connect with a LiveChat agent via the ‘Support’ link on our website. ~Samsung Advisor

Hi Bsaathoff73, Thank you for your feedback on the lip sync issues you're experiencing with your Samsung U7900F TV. This may be related to the content source, but if you're noticing the audio delay across all sources or channels, especially when using an external speaker setup (soundbar, receiver, etc.), there are a few settings that may help: 1. Adjust Digital Audio Delay. You can manually increase the audio delay to better match the video: Settings > All Settings > Sound > Expert Settings > Digital Output Audio Delay 2. Enable Audio Pass-Through. Samsung TVs include an audio pass-through option, which sends the audio signal directly to your connected soundbar or receiver without additional processing by the TV. This can reduce delay when using external audio devices: Settings > All Settings > Sound > Expert Settings > Digital Audio Output Format > Pass-Through 3. Check for Firmware Updates. Ensure your TV is running the latest software, which may include performance improvements related to sound or sync: Home > left directional key > Settings > Support > Software Update > Update Now If the issue continues after these steps, please contact Samsung Support for additional troubleshooting or assistance. We’re here to help at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat and additional support resources are also available through the Support link on our website. ~Samsung Advisor
