Monitors and "Ultra" 4k TVs - two many circles in my head

[Busted Knuckles]

Doing a pretty stout remodel on the new house and one of the things getting built in is a huge (much bigger than it needs to be) 4k TV. And of course anything worth doing is worth doing 5x more than it should be done.....

So HDR is hitting TV land and all the marketing hype contrast ratios.......

Has anyone played w/ any of the higher end Sony/Samsung 4ks to see the number of stops they can display - I am thinking of taking in a scale to my local best buy and loading up some images and see how many steps.

Anyone do this yet???

Also I thought I read a new set that will be 4,4,4 bit depth vs. 4,4,2 current high.


Thoughts and considerations???

Mike - I don't know anything about television technology, except I really want to see a photo of your installation when it is done!

The comedy is that we have a "short" list of mods we want to make to the house we bought in June - as one step became two that became 3, we got all the way to 40% of the price of the house - even though we got a good deal, it wasn't that good of a deal. . The TV is not one of the mods (I stopped camera stuff for a while) so it isn't subject to the resale budget compromise.

Got confirmation that Sony higher ends are 10 bit (4,4,2) and the recent model has some sort of tone mapping to HDR the shadows.... I guess.

At one point in time SONY built the best TV's in the world. I became a loyal follower. Then I bought a 55" five years ago. About the third year it started having a bad picture when it was turned on. It would warm up after ten or fifteen minutes it would be work itself out. It was getting worse and I decided to check in to it. I found that it was a common problem with that model. So bad that Sony had actually extended the warranty several years. Of course I found this out six months to late to have the TV exchanged out under warranty. It was a high end model at the time I bought it.

I have been looking for another TV, and will probably buy one after the first of the year. I suggest you read the reviews closely. There are several models that SONY has right now that have multiple complaints about Light Leaks. One model is priced in the mid range and has awful reviews from buyers, for a TV that cost several thousand is ridiculous.

So maybe you will buy yours soon and lets us know what you decide. It might save me some leg work.

The wife bought a Samsung 55" 4K TV about a month ago. It's been a good TV so far. I think we paid a little less than $900 for it.

You will need to let us know how this works out and the results of the testing. I am kind of toying with the idea of getting one to use as a monitor for tethered shooting in the studio if I can find one that is suitable. Not something that makes it into too many reviews for some reason....

I bought a HDMI cable to attach to my 55" Sony, plugged in the 7D II with the microphone I just bought and made a video of our Christmas. The grandkids had a blast watching themselves on TV. The Picture was great.

For the purpose of tethered shooting I wonder if there would be a benefit from a 4K monitor. The 7D II will not shot 4K, I would think that if you were in live wouldn't see a resolution beyond that. Or would you?

Performance update - Awesome.

While that start up from a cold start is much faster (thanks to the SSD drive) the real tell of the tape is the stitching of the mega pano. You might recall I did a 200+ frame pano of the east side of Logan's pass (take w/ a 5dSr). Well on my month old i7 laptop 12 g ram, 4g dedicated to the graphics card, it took 10 ish minutes to load the images, and a casual cup off coffee to align, and then a leisurely lunch to render the 65k x 30k (1.96 gigapixel) image. Well the new box did these tasks in the following time frames - a little under a minute to load all the images (229 of them), and just about 30 seconds to align and then perhaps a full minute to render.

So I am pretty happy with the oomph that this system has. I have yet to optimize the RAM drive(probably won't at this point), etc, etc. this is pretty much straight out of the box.

With gigapixel results a few a minute or two away vs. hours, I a getting stoked to go do some more of this type of work. I am still working on the real graphics monitor. The only draw back now is that it makes the uber images of a 5DsR and one of the uber sharp tele's more available from a through put perspective may trigger a relapse of GAS. No new cool thing is ever the end - it is always a new beginning

Tethered for stills not video using Capture 1. Allows far better image review during a shoot than the tiny screen on the back. Easier to check focus, look for dust on objects, and review composition as well on a larger screen. A large display makes it easier for me to find, and correct, the little details that aren't even seen in small screens. Creating a monitor profile is required for proper colour reproduction which is why I am curious as to the colour gamut and tonal scale reproducible on current crop of 4k TVs. Less expensive alternative to big graphics quality monitors with potential for other usage as a bonus item, at least when available content catches up to the resolution factor. Maximum resolution for second display is determined by OS and software in use for this application not the video specs.

Update: In short not much.

Chased around and around in circles. I took a flash drive to my local best buy with several pics and loaded them up on the Sony, Samsung, LG (OLED) and Sharp.

I could see the difference between the UHD and SUHD series Samsung and $ for $ the Sony had visibly better color rendition and capacity (could actually see the difference between 8 and 10 bit color) the SUHD and the Sony were very similar but was a bit more expensive. OLED was certainly nifty but not sure if that was the presets vs. fully calibrated. The Sharp was adequate - couldn't really get to the color adjs, just preset "vivid" what ever that is.

None of the images were ugly, but better was better.

What I don't have a comparison with a full on graphics monitor - then again I doubt I am going to really go there regardless.

I am thinking of TOL sharp, just because it has the widest color gamut and the intrinsic contrast is flatter than the others which seems over cooked. As well as least expensive so if it is this doesn't work not too much gone. The other leading option is the Sony TOLs (top of line).

Thoughts?
