Toshiba U79 and U80 Owners Discussion And Review !!

[BLASTO]

• Most of his video he's comparing off-axis which is not how you'll be viewing the TV. Else you'll buy an IPS.
• His camera is likely exposing for the Samsung, which is why Hisense looks washed out since it's brighter and getting overexposed.
• Comparing based on a camera which likely can't even capture the TV's dynamic range is the worst you can do while comparing TVs. Either trust hard metrics or trust what a 'trusted' reviewer says.
• Unless the guy is using a RED or some high-end camera and grading in HDR, you won't be able to accurately determine which TVs look better.

Also, U7QF is a different panel and uses different processing than the U79 and U80. So no point posting it here. Rather post it in the Hisense thread.

Please don't post videos of folks who don't know what they're doing. It gives clicks to them for mediocre work and misleads forum members.

It would help to look at the channel and other videos from them before dismissing as amateur work.
People here make their own opinions based on data points. Comparison videos are better than being locked up at home with no inputs at all.
Also I guess iam giving sufficient disclaimer to not form wrong conclusions.

If you only want to believe rtings, the tv has very poor viewing angles even for VA, motion processing is amoung poorest aroung TVs and local dimming is not very impressive. All of which is discredited in this thread. Then where are the numbers for toshiba supporting this narrative? You can't choose to be objective about what benefits your narrative and subjective about others.

IMO, every input counts. If not anything it will provide insights on the DNA of the company. Admittedly, hisense is a mixed bag of DNAs due to acquiring different companies like sharp and toshiba. But, that they favour details over blacks and will produced raised blacks will not change as they stand for this. Some might prefer, some might not. People can form their own opinions.
If this is purely owners forum, then there should not be any purchase decision queries. You cant avoid that. So any bit of information to aid/dissuade the decision helps.

I can make you an 100% to 80% white slide if anyone wants to see how it looks...

And a lot of people watch 65-inch TVs at 8 feet.

That's not the same thing at all, since there will be a gamma transfer function applied to the signal. sRGB signal has a gamma of 2.2, so the 80% will actually be displayed at 61% of the brightness of 100%.

To display 20% loss, you'll have to display 100% and 92% signals, so that they differ by about 20% after the conversion from signal to luminance.

This TV does have mediocre viewing angles, rtings didn't test motion processing(response time =/= motion processing), and local dimming is not that great as well. None of that is discredited on this thread. However, the TVs in this price range do even worse on those metrics. This TV has equivalent scores in HDR movie and movie scores to the X9000H. For other uses, I'll never buy this TV which I've been saying on this thread and other threads as well.

Again, those results are not to be taken at face value. The raised blacks and other issues are bad yes, but only when you compare them to top of the line TVs

I have demoed the Samsung TU8570 and not impressed at all.
The issue was lack of brightness. May be due to shop conditions, but sony x7500h next to it looked much better and brighter.
Samsung will likely struggle with HDR content.

Did u happen to demo the toshiba in any of the reliance digitals? Locally they have stock but no demo.

Fair enough. I didn't take gamma into account. 2.4 is also what's used by many in dark rooms, so that'll require different calculations.

Nonetheless, 20% actual brightness loss is stil noticeable...to me at least. I'm again watching the IPL match on a VA panel on iffalcon TV. The bar at the bottom is noticeably dimmer on the other side. If I move my head by leaning to that side, the gradation reverses.

>>>>The Hisense H8F has a slower response time than other TVs we've tested recently. This results in more noticeable blur behind fast-moving objects.

>>>>This TV has a 60Hz panel, and has an option to interpolate motion up to 60Hz. Unfortunately, it isn't very effective, and during testing we found that it would stop interpolating every few seconds, causing the frame rate to constantly jump.

These two are notable motion deficiencies. A good motion processing picture engine line sony x1 or Philip's p5 could fix both of these. Can see in the comparison videos that I have posted earlier in different threads with comparable hisense models. Could be an issue to many but if did not affect people migrating from plasma, it is improved by the cevo engine. Otherwise there is no way to not see these.
An input nevertheless to look for in store demos.

2.4 would make you use even closer values than 100 and 92. Also, the human eye gamma is also 2.5 and 2.2 in dark and bright rooms respectively. So the 20% loss won't look 20% to you. If the VA tech was so bad, it won't even exist.

Also the 20% calculation was based on diagonal, but VA panels don't degrade equally on vertical and horizontal. So instead of 55" we should have taken the 47.9" instead of 55"

I personally don't see anything here. Maybe you're more sensitive to it than I am. I'm more sensitive to contrast going away, and that starts to happen around 45 degrees aggressively. So up to 45 degrees it's fine to view for me. The brightness is less sure, but it's less for the entire panel if you're viewing from that angle. So you don't really notice. The panel end to end is not that bad.

>>>>The Hisense H8F has a slower response time than other TVs we've tested recently. This results in more noticeable blur behind fast-moving objects.

That's not motion handling, it's response times. This will be noticeable in 60Hz content for sure. But that's not movies or TV shows. I'm well aware that I'll never use it as a PC monitor.

>>>>This TV has a 60Hz panel, and has an option to interpolate motion up to 60Hz. Unfortunately, it isn't very effective, and during testing we found that it would stop interpolating every few seconds, causing the frame rate to constantly jump.

I've already mentioned to turn motion processing off on this TV. It's horrible, and a bad point of this TV has been mentioned multiple times. That's why this TV got bad scores in sports and PC gaming on rtings as well. However, that does not impact movies, TV shows and the 30Hz sports telecast in India.

If you were going to watch 60fps broadcasts of fast-moving sports on this TV, this TV is not the one for you.

However, comparing based on a capture on a camera is the wrong way to do it. Vincent from HDTVTest tells to not base picture quality on what you see on his camera, even if he has a high end gear. A camera's white balance and dynamic range, along with the exposure settings can massively alter how the image looks in real life.

It's also similar to basing your soundbar purchasing decision on hearing it from a youtube video. That's not the way to do things.

You took 55" in your calculations. I didn't. I took the length of the TV, which gave me approx 26° as the angle

Like I said earlier too, if you feel it's fine at 45°, great. I don't think so. I don't like VA panels even head on. Would I take them over IPS? I have since the past 6 years. Doesn't mean I don't notice the deficiencies.

Again, you can search by name. I have mentioned long ago before you were here about VA panels needing wide angle filters at bigger size, as at at 75-inch size at 8-12 feet, even a clean panel will seem to vignette to varying degrees.

I have repeatedly mentioned subjectivity being a factor in this. Brightness loss is there. Mentioning it is not spreading misinformation as you claimed.

What if the person asking will be like me and not like you? At 45° off axis from the center, I feel VA panels look like shit. At 30° only there is a noticeable warm hue and highlights lose their pop.

Clearly you don't feel the same way, and that's alright. Let's end this here now. Subjectivity is strong as established. Brightness loss does happen as I presented in my scenario.

Those who had doubts have both the sides now. Let them decide where they fall. They have all the info they need. So I bid adieu...again.

Just adding a pic I got from about 40-45 degrees from centre for reference(zoomed from 8 feet).

This is where it starts losing contrast. Again, brightness loss is there from viewing head on, but across the panel it doesn't seem much to me.

 

[Rane-2020]

Its better if people discuss issues and reviews related to toshiba u79&u80 on this thread

Can have a separate thread for Tv angles.where we can have an informed discussion on same.

Instead of this shot, take with a white slide.

White should actually do better than this due to no contrast in the image while this shows contrast loss on the left. But surely, will do tomorrow and tag you. Currently the TV is on IPL duty.

Now this is a 40-inch VA panel from 8 feet away. A 55 inch will have more gradation and a 65 inch one quite a lot more.

Dirty screen effect showing more on camera than it does on screen, but still, it makes the example clear. When viewing from one edge, the DSE seems worse on the other side and then on leaning towards the other side, it shifts and now seems worse on the other side.

Also note the slight warming of the far side that also switches. It'll happen even more on a 55 inch TV.

Not everyone might notice it. My point is that it does happen enough for me to notice it.

A straight on shot of same for comparison would help. A 25' would help better. Dark room is even better if you can do.

Thanks,

 

[Marakk]

About 30° off axis. Tell me that's not noticeable...

My room doesn't allow 45° without getting close to TV, so I'll stop here.

Exactly. Need something to compare with, and something that has been shot with the exact same camera settings. So camera needs to be on manual mode.

That's not the point, is it. The TV will obviously be dimmer at 45 degrees when compared to 0 degrees. What my point was that the TV is quite watchable at 45 degrees and doesn't look like absolute crap. When you are at 45 degrees, all you look at is TV from 45 degrees and not both at once.

If I'm serious about picture quality, I'll watch from 0 degrees. Even an OLED has rainbow effect at wider angles and luminance loss over 40-45 degrees is there for all panels due to plain physics.

However, the gradation issues I'll definitely get images of when I get the chance.

I'll get a couple shots tomorrow. But the ones from @Marakk look really bad. I'll get the same pure white image in all cases.

 

[avtar2008]

My new TV will be placed at exactly the same location as the current LG Plasma 42" TV (see attached pic).

If I decide to buy Toshiba U79, do you think I may notice a loss of contrast and color while sitting on my left/right side chairs that are approx 7 feet away from the TV?

View attachment 50678

I dont know if angle would be right or wrong, but if I had to watch at such distance, then I would not settle for anything less than 65" or a 4k projector.

Moderator has already warned everyone regarding forum etiquette so guys keep that in mind.

As promised, here are some shots. Remember, a phone camera (especially my OnePlus) has much lower dynamic range than human eye, so the difference is vastly exaggerated in these photos. I've included my monitor (LG 27UK650) which has almost perfect viewing angles as a control as well. Again, the TV looks much more even in real life than the photos due to how the camera processes.

As you can see, the TV doesn't look any worse than the monitor. Now, the monitor is a bit closer but they both look almost perfect with the naked eye and much better than the photos. First 2 are the TV, last 2 are the IPS monitor. Please excuse the warping in the photos as I wasn't perfectly in the middle of the TV height and was standing, but that should only deteriorate the quality from there.

Photos are taken from 8 feet from the TV, 4 feet from the monitor. Had to crop them to reduce size, but they are taken from both edges of the screen for both screens.
