Hi Daniel, We appreciate your feedback on the Samsung TU7000 TV's delayed response time you’re experiencing. Please be sure your TV running the latest Firmware. You can check this by going to Settings > Support > Software Update. You may also want to further optimize performance with the self-diagnostic tool, which checks memory, frees up unused cached memory, and closes background apps. Go to Settings > Support > Device Care > Start Device Care. I hope this tip helps improve your enjoyment. For more help, please call us at 1-800-SAMSUNG, 8 AM – 12 AM EST, 7 days a week. LiveChat with an agent as well as manuals, software, and warranty info can be found at the ‘Support’ link on our Samsung website. ~ Samsung Advisor
