Thanks jsdad , very good post. It's interesting though that the black levels are such a big thing when it comes to tvs these days , I honestly really don't mind if the blacks are a little bit grayer than they are supposed to be , I care more about the contrast and the sharpness , the clarity of the image , but may be those issues are connected , I don't know. It's obvious that the 850 PQ is better but if its only the black levels , I think I'll just stick with a cheaper 750 .[/quote]

Black levels will affect perceive contrast, infact many say that black levels are the number one feature for a set.

A respected doctor at the U Of M told me its better for the eyes when you watch tv at night with some kind of light on....just what I was told. My wife and I watch alot of movies in the dark and with a light on as well so its up to the person really. As for the HX850? Its an excellent tv no doubt about it and if you have one or get one you will enjoy it. The HX750? As a proud owner of one I cant say anymore about it then I already have said. But I will say I have NO problems with how deep the black level is on the HX750. I think its outstanding.

Now I'm confused, I thought the blacks would be blacker in a dark room, lighter in a bright room with light reflecting on the screen

Your perception of light is affected by the amount of ambient light.

Image a single light bulb in a black room, versus a single light bulb in a bright room. You will hardly notice the light bulb in a bright room, and you will not be able to avoid the light bulb in a dark room.

We are not talking about blacks, so much as appearance of the backlight illuminating the panel, which is more noticeable in a darker room.

It's summer. The sun is shining. You're looking at the horizon. A big, bad weather is coming, with large, dark black clouds. One hour later it's all over you and has concealed the sun. But are its clouds still as black as before when they were looming over the horizon?

lol clancy! What the heck are you doin buddy? Thats the funniest expanation I have ever read.

Dude what the heck? You have me lost and scatching my head. The last thing you would ever want is light reflecting on the screen .

Regarding my random reboots: Yesterday the TV rebooted 3 times in one 4 hour viewing session! Twice during me watching Bluray and once more on cable. Looks like the call will be made sooner rather than later...

Yeah that's not normal at all. Good luck!

I got my HX750 3 weeks ago - it was a replacement that Sony offered me for the EX750 I had that developed some stuck pixels. Apon switching the new one on I found a bright green stuck Pixel. I got onto youtube and played one of those HD stuck pixel fixer videos. 30 minutes of rapidly changeing RGB did the trick - stuck pixel no more.

I should point out that I tried this on the previous Sony I had but it did not work but it worked brilliantly this time around on the HX750.You might want to try it.

Cheers.

Glad it worked out for you sketch.

So I decided to use CNET's settings and the picture looks terrible. It looks very dark, and whites look yellow. Any suggestions?

Leave the wifi turned off on the TV and see if that helps.

Don't use them?

If you dont like Cnets settings then dont use them. I used them when I first got my tv and changed them. I use the settings that were givin on lcdtvbuyingguide.com except I left on Black Corrector (Medium) and have my ACE on low. They use Spectracal CalMAN Pro V4.6.3 which in my book is the best for calibration.

I was originally going to go with the hx 850 but I have decided that its not worth the extra money.

Now its between the 50" ex 645 and the 46" hx 750 for around the same price I also don't care about 3D.

The cnet review of the ex 645 stated that it had better PQ and way better black levels than the more expensive hx 750.

But I find this very hard to believe since the hx 750 has frame dimming while the ex 645 does not.

The most thing I'm worried about is flashlighting. Does the frame dimming help reduce the flashlighting compared to the ex 640?

And how does frame dimming work? Does it just dim the entire screen at dark/night scenes only?

Can frame dimming be turned on or off or even be adjusted?

While watching a movie in a dark room can the letterbox bars be seen?

First off I wouldnt believe everything you read on Cnet, their reviews can be skewed at times. Second regaurding your question about flashlighting on the HX750? It seems it varies from set to set, some people have those issues on their set and some dont but that just doesnt only apply to the HX750 but all HDTV's. You cant turn off frame dimming on the HX750 and lastly while watching a movie thats Letterbox I cant see the black bars on my set. They are there obviously because of the aspect ratio of the movie.

Thanks for the info.....I might just have to ignore cnet and get the 750 then.

Speaking of cnet are their settings even trustworthy or are they a joke?

Does cnet use special equipment or do they use their eyes to come up with calibration settings?

I am also going to be using the 750 as a monitor for my 2012 mac mini......I hope there isn't any compatibility issues.

Hello,
I noticed that the specs list the speakers as on the rear but I don't see any speaker ports on pictures of the back side.
I do notice 2 "humps" on the bottom though which leads me to believe that perhaps this is where the speakers are and that they are actually down-firing.
I just ordered this set and a very low profile mount. The thought about the speakers being blocked by the wall crossed my mind.
Can anyone confirm that the internal speakers are at the bottom and are down-firing?
Thanks.

I think Cnet's setting are ok and they claim to use the Spectracal CalMAN Pro V4.6.3 calibration tool but dont quote me on that.


The speakers are downfireing and the humps you see are where the speakers are. Believe it or not the built in speakers aint that bad but a tv as good as the HX750 is it deserves a surround sound system or a good soundbar.

I guess I should have been more specific in that i was asking for suggested settings. I was watching the 49ers game while playin with the settings and CNET's made the jerseys look yellow. I switched to a few of the preset screen selects and BAM......bright white jerseys. Steve I used the settings you suggested and it looks a lot better

Good deal. Glad I could help.

Helping a relative with their new 55hx750 and cannot get the hdmi Bravia sync to recognize the ps3. It recognizes when it's turned off when you hit the input button but when you go to the hdmi settings then device list and hit enable it says no hdmi devices found. All that is connected is the directv hd box and is into the hdmi 1 input. The ps3 is in the hdmi 4. Any ideas? We want it to flip to the ps3 input automatically when it's turned on.
Edited by boatbuilder42 - 12/27/12 at 7:57pm

Its gotta be something with the PS3 because if you have the "Enable" set on the tv it should recognize it, you say it does when its off. It also could be the HDMI cable.

Same thing the Sony guy told me regarding my last set. So I did that and it stopped. Then I said "So am I just supposed to stop using the WiFi features of my TV now?" and they decided to replace it in full. Hopefully they do it one more time.

If they replace your set this time and you still have issues then I would return it and get your money back. You seem to have no luck when it comes to the HX750 gator. I feel for you buddy because I have been there with a company called.......Samsung.

I just recently joined the HX750 club (got the 55") after owning an EX640 for a few weeks. I was not happy with that TV at all and so I took it back before my trial period was over and exchanged for the HX750 (of course I also had to pay the difference). The 640 had really bad corner flashlighting (in all four corners!) and not ignorable uniformity issues, among other things. I'm happy to say that the 750 is everything I was hoping the 640 would be and more. Better features, better menus, slightly better off-angle viewing, better everything! Most importantly, though, and I may be among Steve as one of the lucky ones, but absolutely zero flashlighting or uniformity in dark scenes!!! I know what to look for too because as I said the 640 had those issues bad! I'm quite content now that I have it calibrated the way I want (more than happy to share with anyone interested btw!).

My only question is if anyone knows if it can stream videos from iPhone/iPod Touch? I can't seem to get it to recognize any of those devices. Cheers!

Welcome to the HX750 club. I am interested in what your settings are so post them if you have the chance. Cant help you with the iPhone/iPod thing being I havent tried it. Again though welcome aboard.

Thanks Steve! Like you I'm a pretty happy camper with this set. I usually find CNet is a decent and mostly trustworthy site (with some obvious biases from time to time), but they really got it wrong on this one. They must've gotten a defective unit for testing, especially when comparing to their 640 review which was a FAR inferior set in my case. In any case, I did try CNet's calibration settings and absolutely hated them! THX from the T2 BD was okay but made the picture too dark imho. A few others I tried left a washed-out look as well that I did not care for (I'm pretty picky). Here are my settings, it took me a while and a LOT of tinkering to finally get to these but I'm quite pleased with the results (especially for movies on BD!)

Picture Mode: Cinema 2
Backlight: 2
Picture: 82
Brightness: 40
Color: 50
Hue: 0
Color Temp: Warm 2
Sharpness: 24
Advanced Contrast Enhancer: Low
Light Sensor: On

Everything else: OFF

Of course, results may vary depending on room, lighting, preferences etc. I have a whole other setting for sports, but I don't use it as much, only when I'm dedicated to sports for a while. CHEERS and Happy New Year!

Hi all.

I am looking at Tv's again as my Panny plasma made a loud popping noise the other night and the screen went black.
Still waiting on repair shop to open to see if it is worth repair.

I have read through this thread and interested in this tv.
The one I am looking at is the 55hx751 from Costco here in Kingston.
It comes with 2 pairs of 3d glasses.

Coppertone did you ever find out if this is the same as the 55hx750?

I do a mixture of things with tv, hd and sd programming, bluray, and fps gaming, BO2 and MW3.
I know some of you have said gaming is good on this set but I am interested in fps gamers thoughts as that is the most type of gaming I do.

Thanks in advance.
