Cliff, Samsung remotes are designed to be convenient and useful, but we understand if you’d prefer to use a third-party remote, whether it’s a universal remote, a game controller, or something else! Whether you are replacing a lost remote or using an alternative remote to help reduce clutter, a third-party remote is a great option to use to control your Samsung TV. If you need further assistance, we would be happy to help! Please feel free to contact Samsung Support at 1-800-SAMSUNG, available from 8 AM to 12 AM EST, seven days a week. You can also chat with us on Samsung.com for immediate assistance. ~Samsung Pro

Hector Gomez, We appreciate your feedback on the response time, and for optimal performance, we ask that you please ensure you've got the latest firmware version installed on your DU6900 TV. You can check this by going to Home > Menu > 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: Home > Menu > Settings > Support > Device Care > Start Device Care. If you need further assistance, we would be happy to help!
