I was debating with going with the new 5 series or the 6 series. I decided to go with the 5 series and let me tell you that I am not disappointed at all with the purchase. I thought I was going to be missing some of the features the 6 series has (like mini LED's and higher actual refresh rates). But the 5 series really surprised me. The QLED technology and the wide color gambit built into the panel looks really good. Colors just seem to pop and they look very accurate out of the box. Of course, some-fine tuning may be needed to adjust it to what you think looks best . But overall the default settings are fantastic.
The HDR is also pretty good but not perfect. This TV isn't able to get bright enough to experience true HDR. But I think the HDR experience it does provide is rather good for its brightness. It also has Dolby Vision support that looks much better than the typical HDR 10 standard. I really enjoy watching content in Dolby Vision as it just looks better overall.
Another plus is the Roku operating system built into the TV. I have always felt that the Roku OS is one of the simplest and feature-rich TV OS's around. There are plenty of apps to choose from. Netflix, Hulu, Amazon Prime Video, Disney +, and plenty more. It makes watching content from any streaming service super easy as you don't have to hook up another device to stream.
I also use this TV for gaming. The input lag is very low and inputs feel smooth. Make sure that you enable game mode in the TV settings. It really makes a difference in the amount of input lag from the controller.
Overall I would say that this TV is a must-buy! Sure it doesn't have some of the fancier features. But it's also a lot cheaper and provides a fantastic picture that anybody will love!
