So there's a huge difference, but that's normal when comparing a TV that's been out for a year with one that's just arriving – but it does mean that it's certainly no slam dunk to choose the QN90B for its upgraded when the QN90A is fantastic and so much cheaper… while stocks last. The other five QN90B screen sizes match those of the QN90A range. The QN90B range also includes six models, but tops out at 85 inches rather than 98. In 2021 Samsung launched no less than six QN90A models, ranging in size from just 43 inches all the way up to a monster 98 inches, and with 50, 55, 65 and 75 inch models filling in the gaps. It pops in and out of stock at some retailers, so it's likely a great deal if you can find one.Both the QN90B and QN90A are among the best TVs available today, but let’s go through all the differences, to help you decide which is best for you.

It has few advanced gaming features, so it's best suited for casual gamers who don't need the latest and greatest gaming features.

Lower resolution content isn't upscaled as well as other TVs, and there's significantly more banding in areas of similar color. It's still a cheap TV, though, and it has limited picture processing capabilities and fewer features than the more expensive models on this list.

If you care about that, a mid-range or more expensive model like the Hisense U6H is a better choice. HDR content looks good, with visually appealing saturated colors, but it's not bright enough to bring out the content creator's intent. It delivers decent picture quality overall, with excellent contrast, but it lacks advanced features like a local dimming feature, and it can't get very bright to overcome glare.

TVs with Quantum Dot technology usually aren't the cheapest, so this TV stands out for its incredibly wide color gamut, making it the best cheap QLED TV. The best cheap QLED TV we've tested is the Insignia F50 QLED.
