    LG is OLED

    I’ve always marveled at the OLEDs on display at BJs and Sam’s and knew I had to have one. Just brought it home this past weekend, hung it up, and enjoyed the NFL in ways that I never could with my prior LCD/LED TV. The colors are true and deep. The OS is unlike no other and easy to navigate with the magic remote’s cursor. No issues whatsoever so far and can’t wait for more sports to watch. Bought the 5 year warranty just in case anything hiccups down the road but I don’t think there’ll be any but I’m covered nonetheless. The salesman at the store tried to sell me a TCL mini-LED and it looked great but this one is hands down better. LG even makes the OLED panels for almost every other TV manufacturer making it a no brainer to go LG.

    LG webOS tv

    TV picture is great. Remote control takes some getting used to, as the "wheel" is often difficult to use. Largest complaint with the TV is its compatibility with soundbars. Have attempted to install a Bose soundbar and a Samsung soundbar, to no avail. I may have to spend more to get a LG soundbar for compatibility which is aggravating.

    Just amazing.

    This TV is fast and very bright and colorful. We are so happy we decided to spend a little more and get so much better quality.
