Hi Laurie, I’m sorry to hear about the issues you’re experiencing with lag time. To ensure performance is fully optimized, please make sure your TV is running the latest firmware. To do so, go to Settings> Support> Software Update. You can easily update from there if necessary. Next, I recommend utilizing the self-diagnostic tool, which checks memory, frees unused cached memory, and closes background apps. Go to Settings > Support > Device Care > Start Device Care. If you need more help, Samsung is here for you. Please call us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
