Sorry, there was a problem. Please try again later.Absolutely! While watching content click the asterisk (*) button on your TCL Roku remote to access the Options Menu, and go to TV brightness and select which ever option works best for you. The options include Brighter, Bright, Normal, Dark, and Darker. You can also go to "advanced picture settings" in that same menu and adjust brightness there as well. Hope this helps! Thank you, TCL Customer Support
