Ease of Use:


  • Great TV for cord cutting
    Reviewed by Anonymous reviewer - October 28, 2021

    after trying several budget tv’s that all had panel defects, decided on spending the extra money on a higher-end smart tv. the saying you get what your pay for is an understatement based on my experience with other lower-end brands and the samsung qn90a panel does not have any of the previous panel issues. all content has a excellent picture. upscaling lower quality content was a concern for me as well as motion handing for sports. tv does well on both with older shows like friends and seinfeld looked good and newer shows like chicago med looked fantastic which was as issue with the budget tvs on some shows. any video source you throw at it has good picture quality with contrast, deep black levels, vibrant colors and minimal blooming. sports viewing is great also with no motion blur.

  • Exceptional for about a week
    Verified BuyerReviewed by Bill - December 31, 2021

    The picture quality is as stunning as the reviews convey (Rtings, CNET, etc). The tv is also very easy to set-up and use. I marveled at this tv for more than a week when it developed a light spot on the bottom left quarter of the screen (it's a little tough to see in the images because of light reflecting from a lamp). Best Buy could not exchange the tv because they do not have another in their inventory in the USA. Samsung is treating this as a warranty issue, but it will be at least another week before the local technicians have the parts to repair the defective panel. I do not know what I will do if they are unable to satisfactorily repair the tv.

  • Poor quality & after sales service
    Reviewed by JReynolds - March 4, 2022

    I purchased the 75’ QN95A in October 2021. Since then I have had a issues with the TV. It has been returned under warranty once and when received back the fault/manufacturing defect had not been repaired. I have subsequently made a further service request under the warranty but the retailer and Samsung are refusing to honor the warranty as Samsung Switzerland claim the TV is in working order. The attached pictures clearly evidence it is not. It may be that I am unlucky in receiving a damaged panel or it may be that there are many others that have simply accepted Samsung claim that this is normal performance. This cannot be an acceptable performance for a 4000chf tv. Aside from the 'jail bars' which are clearly visible in ambient mode and watching content, it is almost impossible to watch any sport on this TV or movies with fast action sequences as blurred image and artefacts making it unwatchable. Very disappointed and I would not recommend this TV. It is unfortunate that the retailer and manufacturer do not recognise their obligations and either provide a replacement or a refund (my preferred option now) and I need to resort to my legal and consumer rights to receive a product in proper working order.
