I don't think you guys are talking about the same set here, my set almost perfect in every level are you sure 750D is same as JU7500? I don't think so and i don't think any Costco has these new 2015 sets. Please check your sources.
I talked to Samsung twice and they assured me there is no difference between the JU7500 and 750D in specs, features and design. It is merely a matter of reatiler specific model numbering. I can remember them doing this with I believe their T.O.C line. IIRC, the major electronics retailers were "750...950" etc. while Sam's, Costco etc.. were "740....930" or something to this effect. Although I am curious why it is $2,797 vs. $2,999. It came to $2,974 after tax. The rep said it's because they always negotiate with Samsung on behalf of their members to carry products at the lowest possible rate and that was the least Samsung would allow. It seems plausible to me so I went ahead.
Straight away I notice the box says "Future Ready" and will meet all 4K Blu-Ray standards through an evo kit. So this confirms for me that a future full size evolution kit will be released next year for those who were worried about these coming with a "mini-one connect" this year. Samsung reps also said as much. There is no Netflix or HBOGO. Are these supposed to be released soon? I haven't tried "Sports Mode." I thought it was just an option in Picture mode but it is a feature all by itself that you switch to. I will edit later after using it.
My initial impression is that the motion is much more natural and fluid than on my HU9000. The black levels are deep, very good even from an edge-lit panel and I'm coming from FALD. I do have some clouding, though minimal and only in a few areas of the screen. There is slight blooming. Overall I say better/more tolerable than my TH01---8550 and HU9000. There is very small dark radial areas in all four corners like when you hit "info" on Netflix. I returned a Vizio M 65 for this very reason but they are faint and much less distracting on the Samsung. They are only noticeable on fully bright, solid color scenes. Color is really vibrant as I have come to expect and a tad over-saturated as I prefer it. There is no banding that I have noticed yet and no flash-lighting. I have noticed dithering but I think that is due to DirecTV.
The up-scaling is about what I expected. Based on
"Salacaks" review though I was hoping DirectV would look pristine as it does on my plasma but some channels/programs look great while others look terrible..... soft, grainy, noise---washed out. I don't have Netflix or HBOGO yet so I haven't seen any 4k on Netflix or how it handles high quality streams to really judge the picture and performance. I fully expect Satellite to look pitiful on every LCD, this is no exception. As I stated though some shows have looked impressive. For whatever reason 4k videos on Youtube that looked terrific on the 8550 and 9000 look soft and grainy like bad 720 or up-scaled 480. "Longwood Gardens" in 4k looked phenomenal on the other Samsung's so this has me perplexed. I hope support for 4k on Youtube just isn't active yet or there is a problem. My Sony X850B looked like this 750D with Youtube 4k, nowhere near actual 4k.
The new remote is so-so and I prefer last year's. I'm not a fan of Tizen so far as I was hoping so much more. It is rather annoying to hit menu and have to navigate through the "keypad" every time to get to the options above. I haven't seen a disable keypad yet, only the ability to move it from side to side. I'm not a fan of the new lay out but the interfaces look slick and modern. The adjustable settings are exactly the same as before. I was hoping there would be more options to adjust the image. I have no clue what "peak illumination" is doing and there is no demo for it. The '7 Wonders' Demo is not as impressive as the demo last year on the U9000. The picture did not blow me away and there is flicker through-out the entire thing. The scene when they are riding the camels through the caverns however is absolutely stunning. I am hoping that, that scene represents the true capability of this TV with a good native 4k source. Then I will be fully content.
The sound on this set is the best I have heard from Samsung, it almost sounds as if there is an integrated sub-woofer providing for a rich bass. The OS has been slightly laggy at times and slow to respond to commands. Not a big problem. Web browsing is indeed faster this year. I have gotten a "network cable disconnected" message about 4 times though and it clearly is not. I have to unplug and re-plug it in then it works again. Probably an early issue that will need a fix with firmware.
Overall I have to say I am not very bullish on this TV. I was hoping for vast strides from last year. I think it is pretty much a re-packaged HU9000---8550 with better motion. I really need to see 4k content to give a final judgement but this is my initial impression. I need more time with it and try more settings with more content out. Soccer on BeIn Sports looks rubbish. Lacking 4k I have not been blown away. There has been no jaw-dropping, "wow" moment. Judging from the demo I'm not sure I will ever have this moment. Hopefully with my settings on Netflix I will be amazed.
