Lunar dev here. Looks like it does support DDC brightness control: https://f.alinpanaitiu.com/nAa7gs/Image.png I checked this on https://db.lunar.fyi using the following query: select control, name from displays where name like '%U3224K%' Can’t be sure about DDC input switching though, I have no way of knowing that it works without trying it in front of the monitor. DDC reports success even if the command failed to s…

Just wanted to say, thanks for the fantastic app. It's the first thing I install on a new computer.

Hey thanks! So happy to hear that ^_^

So, if 25 cm is an optimal viewing distance, 350 ppi is maximum phone screen density required?

25cm is pretty bad viewing distance, a good way to mess up your eyes long term

Good to know. I meant that's where humans can discern smallest details.

I just purchased 2 of the 6Ks and I am keeping both. AMA. I do not understand the complaints about pixel density. The display is 223 ppi, which is the same or slightly higher than Apple displays. I am using them in a dual display configuration with an M1 Macbook Pro via TB4 and a Windows PC with an RTX 4090 via DisplayPort. The KVM feature makes switching back and forth a breeze. I am using 175% scaling (in Windows)…

32" is an extremely common size for 4k at 100% scaling so I can see the desire for 8k using 200% scaling at the resolution. 225-250% would probably be more "proper" densities for such a display but many like to go a bit under standard scale.

It's quite popular, but I personally don't get it. It's too low density for text to look good on it, 24-27" is around the maximum. It's too small to be a single monitor, while being too big to comfortably fit in multi-monitor setups.

I guess it's popular because 32" 4k TVs make the panels cheaper?

> I can see the rainbow effects of antialiasing on my 4k 32" monitor Are you talking about subpixel rendering? Leveraging individual R G and B dots needs knowledge of the layout to achieve increased resolution, and the algorithm should be adjusting (best effort) to compensate for human colour perception with knowledge of the subpixel layout + subpixel size. But usually it might be that the screen has a different layo…

I'm familiar with the subpixel arrangement issues. My display is RGB, according to its specs and to some review I've seen before buying it (I made a point of avoiding "non-standard" panels). I only notice this with very thin fonts, since sometimes the vertical lines end up "in between" pixels. I agree that at some point grayscale AA is good enough. But I've found that that point is at a higher DPI than I get on a 4k…

I also find 24" to be the "perfect" maximum size for a 4k monitor. 27" is close, 32" is clearly too big.

What about the other very large group, like me, who can easily tell the difference but it's very much not worth the price of admission?

I think it must be a visual processing difference in people's brains. I find 30/60/120 equally playable in gaming, but other people here are calling 30fps intolerable. Similarly I've used a 1080p monitor for years and I'm fine with it. I don't need tiny pixels for coding and messing around with pixel scaling on Linux seems more trouble than it's worth.

I think it depends a lot on the way you use it.

30fps might be fine for playing Solitaire, but it is definitely a limiting factor for first-person shooters.

Personally, after a year or two of programming on 30hz, I absolutely want 60hz for office use. Having lag while dragging around windows is not fun. Having a 1080p+ monitor is more about screen real estate than it is about precision: you just can't fit three windows side-by-side on 1080p while still having stuff remain readable.

I don't understand why these monitors are so expensive. I've been using a 55" 8k TV as my main monitor for years and paid less than USD 1000 for it new. Recently I saw a similar deal for a 8k tv again, so making panels at 8k and shipping them around the world at around USD 1000 is certainly still possible, but the Dell 8k is 4000+ and the 6k is 2300+.

Using a tv as a monitor has downsides (Only HDMI, doesn't detect inputs automatically etc) but having 55" of retina screen real estate is such a great experience that I'm sticking with it. The same panel sold as a PC monitor with proper inputs (and maybe a matte screen) would be ideal.

Recently there was an article here on HN declaring that LCDs are on their way out now in favor of OLED. That doesn't seem true at all for the monitor market. The author doesn't even mention that both monitors are LCDs.

In that post [1] some commenters said that the backlight technology for LCDs is the hot stuff at the moment, apparently.

You don't want an OLED PC monitor because it will very quickly suffer from burn-in at the typical locations of taskbar and window controls.

> it needs two (!) DisplayPort cables on a GPU with MST support, meaning that in practice, it only works with nVidia graphics cards.

This is nonsense, of course AMD graphics cards support MST. https://www.reddit.com/user/hubsdocks/comments/rcf6vz/dell_w... Perhaps some weird Linux driver limitation...?

As for DisplayPort, the only semi-modern customer grade video card with four DisplayPorts is the AMD Radeon™ RX 5700 XT Taichi X 8G OC+ RX5700XT TCX 8GP.

I think there are three groups of people with opinions regarding 120Hz vs 60Hz refresh rate. Group 1 can tell the difference between the two and strongly prefers 120Hz. Group 2 can't tell the difference between the two and prefers the more affordable options. Group 3 has not done a lot of comparisons between the two refresh rates, or has used 120Hz displays that were actually in 60Hz mode, or compared lower resolutio…

I'm shocked that group 2 exists at all. Just wave your mouse around and watch the cursor. Or open up quake and turn around while keeping your eye focused on a stationary object.

> Just wave your mouse around and watch the cursor

I just realized that I literally never do this. It is indeed incredibly jarring. even at 60Hz. I think my eyes basically immediately "jump" to where I want to move the cursor, so I don't really "track" it. Do other people track the cursor with their eyes?

3:2 pull-down works for converting 24fps to 60fps. It doesn’t matter if the target f is fields or frames.

The film industry should stop using 24fps, it's a waste of people's time and energy. At least they should move to 25fps which is what most of the world uses as a frame rate, if not 30fps. For the stupid North American non-integer frame rates, just change the playback speed by a fraction and get on with life. Or drop 1000/1001 frames for live, people won't notice.
