    3A.

    Since last year, display manufacturers have been doing their best to convince the consumer that Ultra High Definition (UHD) 4K is the future. The plethora of technological advancements behind these ultra-high resolution displays give manufacturers an excuse to sell a large and avid market of consumers a new TV all over again. With HD finally entrenched as the standard among consumers, it’s time once again to convince them that they’re missing out on the best their viewing experience has to offer if they don’t upgrade.


    Leading this charge is Samsung Electronics, who have released a full lineup of UHD televisions this year. Near the top of their 2015 line-up sits the UN65JU7500, a full 4K (2160P) display that features a curved display measuring 64.5 inches diagonally, 40W of sound output, built-in Wi-Fi and 4 HDMI inputs. Like the rest of Samsung’s new lineup, the JU7500 uses Samsung’s “One Connect Mini” box to provide the HDMI and USB inputs, and also makes it much easier to connect sources to a TV that would be rather inaccessible once wall mounted.


    Design & Features


    The JU7500 comes with a plethora of features, including Samsung’s Smart Hub technology, which offers a variety of apps including Netflix, YouTube, and a broad selection of third party apps including MGo which allows access to downloadable 4K content. Samsung’s design team has done a great job on the JU7500, giving it thin bezels measuring just over a half-inch thick, and a beautiful curved stand that nicely complements the curve of the screen. Due to the curve, the JU7500 is quite a bit thicker in the back than the latest flat panels, measuring about 3.5” thick.

    rear.


    In terms of control and calibration, this is a very well featured set featuring both 2 point and 10 point white balance adjustments as well as a full color management system.


    Color & Calibration


    I measured and calibrated the JU7500 with my X-rite EyeOne Display 2, a rather low end colorimeter and a little out of date also. Regardless, gray scale calibration was accomplished relatively easily and resulted in excellent overall tracking after using the included 2-point and 10-point white balance calibration options. I struggled with color calibration in the CMS, as my colorimeter was not reading properly. Regardless, the net result was a very nice picture that is extremely accurate and excellent for viewing in the home. Here are my final results:

    1.

    In terms of actual viewing, post calibration the picture of the JU7500 is about as natural and organic as one can hope for with an LED screen, and is the best I’ve seen to date. Skin tones and foliage look very natural while primaries have sufficient pop to give the picture a sense of depth and dimensionality. Note the color results here are very likely my meter, and not the set. A replacement is on order.

    2.


    Contrast


    After calibration I was still somewhat disappointed by the black levels on the JU7500, as they appeared more dark gray than black in a dark room. That said, in a bright room with the backlight cranked up perceived contrast improved dramatically. Those who purchase this set for a dark room should definitely consider bias lighting.


    During my contrast evaluation, I also checked for backlight uniformity. It turns out that the curve of the screen does create some noticeable backlight bloom towards the edges of the screen but this is rarely noticeable during actual viewing.

    3B.


    Local Dimming


    I turned on Smart LED initially to see if it improved my black levels on the JU7500, however the zones are very large and this reduces the usefulness of this feature to the point that I personally preferred it entirely turned off. I also noticed some occasional issues with this option enabled in dark content where dimming became noticeable to the extent it distracted from my viewing experience. For viewers who have dark rooms, I suggest you turn this off.


    Motion & Judder


    Motion on the JU7500 was generally very smooth with both 24p and 60p content. Samsung’s ‘Auto Motion Plus’ technology is included in the JU7500 if you enjoy the soap opera effect, however in my case this was left off as I detest the way it affects PQ.



    3D


    Due to an incredibly bright backlight, quality panel and fast response time I found the 3D experience on the JU7500 to be absolutely fantastic, with no visible crosstalk or eye strain. 3D lovers will certainly enjoy this TV.


    Resolution & Clarity


    Samsung’s 4K VA panel in the JU7500 is an absolute delight with respect to clarity, pixel density and sharpness. I reduced the sharpness setting to 10 for my purposes and found native 4K material provided by Samsung looked absolutely great on the JU7500. I also had the opportunity to view some of Sony’s 4K demo material that came with my projector and it also looked stunning both in static shots and in motion.


    When viewing 1080p content on Blu-ray up scaled to 4K by the TV resolution also looked fantastic, though not quite as good as Sony’s competing sets at the same price point.

    I also took the time to test the JU7500 as a computer monitor, turning on PC mode under input settings and enabling UHD Color, which allows 4:4:4 chroma reproduction. While additional calibration via ICC was required to get truly optimal color reproduction in PC mode, the lag was very reasonable for gaming at 4K and looked absolutely spectacular.

    oneconnect.


    Conclusion


    Samsung’s 4K televisions are changing rapidly, with SUHD models already on the market promising eventual obsolescence for the JU7500. These advancements include high dynamic range (HDR) and wide color gamut (WCG), and from what I have seen thus far will not be small improvements, they will in all likelihood be as significant as 4K itself.


    Buyers who are interested in having a top-tier television that is both future proofed and capable of reproducing the best picture quality available would be better served by purchasing Samsung’s latest JS9000 series. For cost-conscious consumers who are not early adopters looking for a full featured media room or family room TV that is an excellent all around performer, the JU7500 series seems to have everything one could hope for at a more reasonable price point than the new SUHD series.


    From excellent industrial design and smart apps to full featured calibration capability and picture quality the JU7500 deserves top marks all around. Held back slightly by less than stellar contrast and black levels and some minor issues with backlight bleed in dark scenes, the JU7500 falls just short of our highest recommendation, yet remains a worthy display for anyone looking to make the jump to 4K. Recommended.

    Definitely got the flat 8500s in my sights, thanks for these impressions Dave, very helpful to compare what you liked about this model vice my expectations for a very similar set.

    Question: the 9500 (or is it 9600) line is better than this? I can never figure out their numbering as to which is best, but higher usually implies best. I'm waffling between Samsung and the latest 4K LG Oled.

    Yes, the 9500 model is supposedly better, but the customer reviews are better on the 7500 model. If you're not in a hurry, I would wait on the 2016 models. Check out the two links below on the 2015 models:

    I see CES already has 8K displays on the showroom floor, does that mean 4K may be short lived?

    The curved sets have been out for a while and I've always been inclined to think it's a gimmick. A curved screen in a theater makes sense, but at home? It seems to me it would reduce the viewing angle. Am I right or do I have it all wrong?

    Dead right. It makes sense if using as a computer monitor or for very near field viewing, but in general it's a really really terrible idea that they need to move on from.

    Hello everyone.
    I'm sorry Dave but I have to disagree with you on the 3D aspects of this unit ..I own the 78 inch curved version of this exact tv (un78 ju7500) and I'm very disappointed at the 3D this tv has ..mine has horrible ghosting on all of my Imax 3d blu-rays ..and out of my 200 plus 3d blu-ray titles i have. over 75 % of them have ghosting on this set..if anybody is into 3D as I am ..I'd stay clear away from this tv set at all cost..I am currently looking at spending thousands more now on a projector and screen to hopefully have clear 3D after spending $6000 on this horrible samsung tv...

    Paul,

    I'm sorry you had a bad experience. I would check to ensure you have your settings optimized - as I saw nothing nearly this bad in the approx. 4 hours of 3D content I watched during the review. It's also possible that something else is going on with your unit.

    I would caution you that a projector is not guaranteed to be any better for 3D. The only common variable with great 3D displays is the fact that they usually use RF glasses - which improves sync and minimizes crosstalk.

    Thanks Dave..RF is what this tv has and I've talked to samsung and updated the firmware and tried different RF glasses thru various companies and I've had the set professionally calibrated and still horrible ghosting..I have all top 30 3D picks on the home theater forum here and everyone of them has some sort of ghosting. .I'm currently looking at the epson 5030ub and the new benq 4050 DLP ..I've heard that DLP has virtually no ghosting..so I'll probably try the benq DLP HT 4050 ...so if anyone has any useful information on this tv or a great non ghosting projector ..please let me know....Love this forum/site ..

    This not an Edge-Lit TV, it is a Full-Array backlight. Can you also write the panel version you have tested. I believe this is very important as different panels have totally different picture qualities for a particular TV model. As Samsung outsources panels to Chinese and Taiwanese companies which produce cheaper and very low quality panels, your evaluation is valid for only the panel version you have tested.

    I've got the Epson 5030ub, and use it frequently for 3D, including many of the titles on Ron's Top 30 list. I'm extremely happy with the projector and its performance. I don't want to derail this thread too much by singing its praises, but there's a thread over in the Hardware/Display Devices section where I wrote more about why I picked it and how it's worked out.

    From what you're describing on your Samsung, there just may be something wrong with that one specific part of your specific TV that the technicians missed - it's rare but it does happen. My LG TV seemed to develop a defect in 3D viewing after owning it about two years. Everything just got less 3Dey on it. I don't know how else to describe it. Movies I watched when I first got the set, which looked fantastic, suddenly looked as if they had very little depth. No idea how that happened or why. Still works just fine in 2D.

    Sad,

    Good catch on the backlight - i've corrected. I do not have the panel version as I had to send the unit back to Samsung fairly quickly.

    Thanks josh..I love the picture on the samsung ..I have some 3D movies that aren't as bad with ghosting and are watchable ..but the majority of them seem to ghost extremely bad as soon as the depth or forward projection seems to go either way a foot or so either outward or backward if that makes sense. .imax 3d blu-ray movies are the worst I've encountered. .they have double ghosted images that are inches apart..like imax hubble 3D I had to just take it out...I have a 5 year warranty on the set...guess I can call samsung and try to get someone out to see if it needs replaced..
    I've looked at the epson 5030 and love to try it but I only have a 10 foot throw distance and I would like to go with a 120 inch cinewhite starling tab motorized elite screen .the only projector I can find that has that throw distance with great picture quality and adjustments that allow to me to use a 120 inch screen is the BenQ HT 4050 DLP ..guess I'm pretty limited on what projector I can use...all of this would not need to happen if I could have gotten a great 3D tv set for $6000 like I thought I was getting...I now have close to 250 3D blu-ray movies and it's heart wrenching to watch them without horrible ghosting...the agony..
    Thanks for the thread and the comments everyone..love this site ..keep up the great work....

    Paul, that to me definitely sounds like something's going wrong somewhere in your equipment chain - I have no idea if it's the Blu-ray player, the TV itself, or the glasses, but that strikes me as a defect of some kind. Is there any possibility of exchanging the set for a new one of the same model to verify that?

    Some titles with extreme forward projection can cause ghosting on even the best sets - and sometimes it's not actually the set but our brains not properly fusing the images - but it doesn't seem right to me that you'd have the same issue on over 200 titles. One or two, sure, I have a couple discs that don't look as good as the others, but the vast majority of my 3D collection plays flawlessly.
