Where are the 8K Monitors?

I disagree about flat. A 1000R(adius) curvature is a 1000mm radius, so if you have a screen with dimensions sympathetic to that you could sit at that 1000mm ~ 40 inch away viewing distance where the pixels would be on axis to you. If you are sitting closer to that, or closer than 60 to 50 deg viewing angle on a flat screen, you are going to have more pixels off axis to you - especially on the sides but if it's a large , for example 65" 16:9 screen sitting nearer on top of a desk it would be looming above you so the uniformity would probably be bad at the top portion of the screen and the top corners, like a gradient that is more non-uniform, (more degrees away from where it should be in the center of the screen) the farther and farther away from you the pixels are. The most uniform should be if your head was aligned more or less at the center of the screen, and where the pixels were aimed as directly at you as possible.

Don't really mind if people prefer curved, and if I were to build a racing sim or something like that where immersion was the key, I might prefer that as well. But never for productivity. And neither does Samsung it seems, based on the fact that when the viewing angles are not as poor, the need for a big curve seem to go away. That said, if people prefer curved, fine by me.

As for plugging in a laptop, the ark and the 900D are both supposed to be able to do tiled multi-input, it's just that the ark is only 4k so it only gets a quad of 1080p real-estate wise and that's not a real modern "multi-monitor" environment imo.

So is the QN900C and I have also an email where Samsung has confirmed this. Actually getting it to work though...
 
Flat is mostly on axis at 60 to 50 deg viewing angle.


Most of the screen surface on-axis (pixels aimed close to you)

Larger fields of the sides of the screen are off-axis when sitting closer, at a wider viewing angle (causing distortion, and also non-uniform depending on the screen) when sitting closer, also lowers PPD

Curved screen sitting at the center of curvature allows you to sit nearer.

No matter what pixel is firing across the width of the screen, it's pointed directly at your eyes

Most curved screens are not designed with an aggressive enough curve and with sympathetic enough sizes/ratios in order to logically sit at the center of curvature.

If you sit at the center of curvature on a screen designed to be viewed that way, as an analogy:

It would be as if you had a beam on the floor connecting your rotation-capable chair to a floor style pillar tv mount on caster wheels, with a flat screen on it. Turning your chair in this imaginary scenario, the screen turns along with it. You are still at the "head on" view radially. Now instead of rotating the monitor with the chair, duplicate the monitor along the curve with several screens and decouple the chair from the screens and spin in the chair. Then, finally, instead replace the screens with a single curved screen that follows the same arc of the circumference of that circle your spinning chair made with the end of the beam, like a math compass making a chalk line on the floor. Similarly, people using multi-monitor setups try to angle their side monitors to face them directly as best they can, it's just a lot more crude of a curve only having a single line segment on each end. Most curved monitors are not form-factors that keep the distance from the screen to your eyeballs equal. A desktop screen would have to be 700 - 750R. The ark could do it if you sat 40" away, and it would get around 60PPD or so.

Gen 1 of the ark couldn't really do other inputs in multi-view but I think the gen 2 can do it. Idk about the 900c, but I'm interested in whether the newer 900D can since it came out after gen 2 of the ark and that one connect box.

QN900C has support for 4 multi view "areas" up from only 2 on the QN900B. But there seems to be some incompatability only giving me "not supported" but will try more when I have time for it.

Was able to get the Multi View working but it seems to require disabling Game Mode which also seem to break 4:4:4 which basically makes it pointless for anything text related (at least compared to an actual monitor).

Can you set the hdmi input to "PC" like you can on a LG? On LG OLED, as long as you set the hdmi input to "PC" in the input selection panels of the TV's OSD, it will be 444/rgb, even if you haven't set the named picture mode to "Game mode". You'll get more lag though due to processing so not great for games outside of game mode.

I'm hopeful that they updated the one connect box on the 900D, because it came after they updated the ark's one connect box in Gen2 of the ark. The gen2 ark's one connect box isn't compatible with the gen1 screen. Gen1 ark couldn't even do multiple external inputs via ports, only if using laggy wireless broadcast.

There are additional "weirdness" with dithering etc that comes into play. It is doable but as a monitor nut, it would have to be better than that in order not for me to start looking into alternatives (lika a 4K side monitor). The Multi view definitely seems to be targeted at "video content" which perhaps isn't that surprising.

Having explored the QN900C a bit to get to know it, it seems like most of that fancy stuff is disabled in game mode, which simply seem to turn the processing into a basic upscaler. This is probably due to input lag reasons I would imagine. Will be interesting to see actual differences to the QN900D, especially as the Neo G9 can do 8k2k at 240 hz so they must have updated circuitry.

Hopefully I will be able to do some side by side comparison with the Neo G9 57" soon, there are some practical challenges as well :)

There must have been some updates to the QN900C/One Connect Box since the first QN900C I tried because I am yet to experience any kind of dropout even at 144 hz while the previous one had them all the time. And this is with the long cable as well. As mentioned before, I noticed that packaging were a bit different the other time around and I also recall thinking that the One Connect box look slightly different, although I could be remembering that last part wrong (it is not the QN900D one according to pics). I am using the exact same setup including cables.

From a QN900D owner's youtube video replies. His replies are a little broken language-wise so far so idk how valuable the info will be.

I doubt it would be more than the 900D is currently (its possilble I guess but would place it more in a lightweight reference monitor price range rather than regular consumer range). The 900D is at a big early adopter price currently though. Gaming TVs and unique samsung ultrawide gaming monitor designs tend to drop in price over the year at least but the pro-arts seems to take much longer to drop in price I think.

other comment of mine about the 900D:

4 - 6, and 10 -12 months out and into next year as the prices drop a lot more from 65" $5000 (now $4500), 75" $6300 (now $5670), and 85" $8000 (now $7200). That's still thousands of dollars more than a flagship 4k FALD or OLED usually is A S90C is 65" $1500, 77" $2000, 83" $3000 for example. Sony A95L is 55" $2800, 65" $3300, 77" $5000.

Personally I'd rather a larger gaming tv or huge monitor decoupled from my desk and set back another 16" to 24" or so behind a 24" deep desk, (depending how large the screen was and how deep the desk was), on it's own stand so that I wouldn't have to sit as close in order to be able to utilize the resolution as added desktop-app real-estate. However, a 32" screen can get the same kind of 60 to 50 degree human central viewing angles at 24" to 30" view distance, screen surface to eyeballs, so it could work. I'm just more comfortable with a more spacious command center style layout now I guess, and outside of full screen media and gaming you might even want to sit a little closer than that viewing angle wise when using a 8k screen as 4x 4k worth of desktop/app real-estate at 6k or 8k 1:1 worth of readable space. The pro art displays haven't been the best for gaming in the past either, unless that changes with the 8k model. It would do better if it upscaled 4k to 8k really well too as 8k is very demanding.

ucx tftcentral review:

The response times showed a few slower transitions in practice, especially for light to dark shade transitions which resulted in a bit of pale blurring to the moving image. At the very top end 144Hz the overall average response times were a little slower than the refresh rate window, and 60% of those measured transitions could keep up with the 144Hz frame rate properly. This results in a bit of added blurring to the image, another reason why the motion clarity isn’t quite as sharp as some other recent high refresh rate IPS screens.

That and the fact that most monitors, especially FALD LCD monitors, are not available in glossy which is a huge tradeoff to me.


I could see where the pa32kcx could be a good choice for some people, and it's good to see more 8k screens, especially designer screens which could help to make more 8k content available in the long run - but I'm looking for more of a larger gaming/media and multi-monitor desktop/app use replacement scenario rather than a higher PPD small desktop monitor with abraded outer layer on it and potentially lower response time. None of the articles I've seen on it have mentioned the Hz at all, which you'd think would be worth mentioning, so the pa32kcx 8k might be only 60Hz too.
