Samsung UN40JU7100F


The JU7100 is still expensive, but not totally outrageous. It lacks the curved form of even more expensive Samsungs, and it also fails to qualify for the company's high-end SUHD moniker , newfangled nanocrystals and all. It doesn't support the kind of...

The Samsung UNJU7100 series is the company's least-expensive TV with true local dimming, leading to very good picture quality with relatively deep black levels. Its color is accurate and video processing is among the best on the market. Unlike most...

It's still relatively expensive, and its overall picture quality falls short of some less expensive TVs.

The Samsung UNJU7100 delivers the same high level of picture quality as some more expensive models, and beats most competitors for style and features.

A Review of the Samsung 4K UHD JU7100 Series Smart TV – UN40JU7100, UN50JU7100, UN55JU7100, UN60JU7100, UN65JU7100, UN75JU7100


The Samsung JU7100 4K TVs offer an excellent combination of top-shelf features and an affordability that's somewhat lacking in the manufacturers even more exotic (read: awesome) SUHD line of TVs and for this reason, they are a great balance between...

Excellent backlighting for an edge-lit model ; Great connectivity options ; Very good OS/smart TV ; Decent contrast and color ; Very good UHD upscaling

More expensive than it deserves to be ; No HDR ; No quantum dots ; No enhanced Tizen OS ; No full-array backlighting

An excellent 4K UHD LED TV, the JU7100 is better than a majority of comparable models from other brands. It’s only defect is the slightly higher than reasonable price tag of this TV.
