Excellent picture quality.
[This review was collected as part of a promotion.] I have had LG Qled for several years which my wife and I enjoyed watching, but when I saw the picture quality of the Oled I was amazed at the difference. The picture is clear, crisp and such a natural colour especially when watching wild life programs. This is an excellent purchase and I highly recommend this TV

Premium TV, budget remote
[This review was collected as part of a promotion.] Premium TV, budget remote. Great TV, really great TV. But what a shocker of a remote control, complete letdown. Seems LG have been told this loads but choose to ignore customer feedback.
