There are individual adjustments for the items you listed, the television is also compatible with many apps that can adjust your television for you, via camera if your phones camera has the chutzpah, i do however advise a sound bar, or ANY external speaker which it has hard jacks for, as it gets a little "tinny" at sound setting 22 or higher, (slightly louder than normal indoor same room voice.) it begins to vibrate with the already bass heavy default setting. as far as series goes, 5 and 6 were TCL's finest works and a higher series will cost you more money without any ability to tell the difference.

Sorry, there was a problem. Please try again later.There are options available to adjust the settings to better fit your personal preference. You can access the Options menu on the TV by pressing the asterisk (*) button on your remote while watching content. Additionally, you can access expert picture settings by downloading the free Roku mobile app on a smartphone or tablet. The Roku mobile app works as a remote and allows you to access additional features like voice search, private listening, expert picture settings, and more. The direct upgrade from the 5-Series would be our new 6-Series. Hope this helps! Thank you, TCL Customer Support
