Our Verdict
LG G4 OLED
Samsung S90D/S90DD OLED (QD-OLED)
The LG G4 OLED and the Samsung S90D/S90DD OLED are both amazing TVs, but there are some differences worth noting. The Samsung has a wider color gamut, so it can display more vibrant and lifelike colors, and it has better color volume, so it can display brighter colors. The S90D also has no noticeable banding in colors, while the LG does have some banding in certain colors. On the other hand, the LG has better low-quality content smoothing, so it's the better choice if you regularly watch DVDs or low-quality streams. The LG also supports both Dolby Vision and DTS audio formats, which is great if you're looking to get the most out of your 4k Blu-ray collection. On top of that, the LG has better SDR brightness, so it overcomes more glare in a bright room.

LG G4 OLED vs Samsung S90D/S90DD OLED (QD-OLED): Main Discussion
What do you think of these products? Let us know below.
Looking for a personalized buying advice from the RTINGS.com experts? Insiders have direct access to buying advice on our insider forum.
We’ve purchased the product and are waiting for it to arrive in our lab.
Would be interesting to see the ANC and sound responses. I’ve heard they have good ANC, but are really thin in the midrange
Morning - any update on when the results on these will be released ? I’m a right eager beaver !
If all goes as planned, we’re set to begin testing them on November 6th, so the results should be available a little over a week after that (roughly)!
Superb ! Looking forward to it. This may not be the thread but it would be interesting to know how they stack up against the Astell & kern uw100 mk II’s which are around the same price. Many thanks
Our testers have started testing this product; is there anything specific you’re looking to see? Let us know in this thread.
Would love to see how anc measures up, and how the different EQ settings compare to the target.
Would also be super cool if you tested out custom eq settings that get it closer to target.
Early access to our full test results is now available for Insiders! Become an insider to check it out here.
The battery life is a bit on the shorter side [the Bowers and Wilkins also has a similar battery life, right?]. How bulky is the case; bulkier than the Sennheiser Momentum True Wireless 4?
Howdy, thanks for dropping by. Here’s a link to a side-by-side comparison of the products you’ve mentioned. The Devialet, B&W, and Sennheiser are sitting at 4.4hrs, 3.0hrs, and 7.3hrs of battery life with ANC on respectively. And the Devialet’s case is about 36% smaller than the Sennheiser’s. If you’re looking for something with longer battery life in a similar price segment it might be worth checking out the Sony WF-1000XM5 Truly Wireless. Hope this helps 8).
