What's your latest tech purchase?

Oh, only the non-zoomed version (at 100%) should be used, the zoom version's just to illustrate what's going on here. You have it at 259% rn, try putting it at 100% and take another photograph?
 
I hope side by side was okay:

The left image got trashed by the upload and looks like ass, very unlike what i see in person so its not included

yeah unfortunately its kinda impossible to see what's happening here from the photograph xd
you have to see for yourself if the unzoomed version moires or not, at 100% zoom

Nah, cant see anything except things being softer

Thing is, when i change back to 1440p some still open apps still have that softness, so i think thats cleartype/windows zoom screwing with them and not an actual monitor issue
Games... games look amazeballs. I wish i had DSC or newer HDMI for 4k 144 :(
 
Welp.
Guess the pixels are just too dense to make out details. Par course for such a display, tbh.

If it however doesn't moire and just appears as a uniform grey (as it should, given enough pixel density) then you're in all likeliness dealing with an actual 4k display. Congratulations!

I'm not the only one - seems quite a few manufacturers are re-using 4K panels for high refresh 1440p, in the 32" market

Makes me wonder if GerKNG can use his monitor at 1440p without any distortion, too
(Wouldnt that be the dream gaming monitor, one where native res covered 4K and 1440?)
 
It looks native. I'm pretty sure they used the same panel in the 4K screens and the 2K screens, just with different inputs

It works great for me cause i can set 4k 60 and use moonlight to stream 3090 goodness to the HTPC in the lounge, with a nice 1:1 signal

In recent generations of monitors it has become quite common for 1440p monitors to support 4k input signals through downscaling so that they support current-gen consoles (rather than forcing the PS5 into 1080p output mode; the XSX supports 1440p). I sincerely doubt that they're using 2160p panels and running them at non-native resolution, not only because of the loss of sharpness, but also due to cost and availability. There's only really one source of high refresh rate 32" 2160p panels now (hence why all the monitor options perform close to the same), and they overall have slower pixel response times than available 32" 1440p panels - and pixel response times don't improve through running an upscaled lower resolution. Take a look at Techspot/Hardware Unboxed's reviews - they show pretty clearly that these are not using the same panels.

It used to be that 1440p panels were simply rejects of 4K panels but yeah, nowadays they often support 4K 60 input for console use.

Example:
A ‘4k x 2k, 3840 x 2160’ downsampling mode is also included by both DP and HDMI at up to 60Hz, as shown in the third image. Potentially useful for games consoles that don’t support a 2560 x 1440 signal but would accept a 3840 x 2160 signal.

Hm, that's weird. Rejects how? I can't remember ever hearing of an LCD monitor sold that doesn't operate at the panel's native resolution (that would make for some very visibly sub-par image quality in most cases), so I would assume that would entail some sort of error spotted early enough in the LCD production process to cut out a smaller panel at lower resolution that bypasses the rejects. That would definitely make sense if the 2160p panel production process had significant error rates (which, judging by how common dead or stuck pixels still are, it likely was), and would reduce waste significantly. But I can't imagine any way a native 2160p panel would fail to work at 2160p yet would somehow work at 1440p - the panel doesn't know anything beyond that every pixel is fed with data, after all, and any upscaling like that would need to be handled by the controller.

Actually my previous Samsung CHG70 would do native 4K 60hz on HDMI but 1440 on DP
 
Wow, interesting! I can't imagine that being very common, but as the article notes, it might definitely have happened in cases of low panel supply or high demand. 2160p at common monitor sizes is starting to get to a pixel density where the disadvantages of running non-native resolution are much smaller than they used to be (one of the reasons why I'm aiming for a 2160p monitor for my next upgrade myself - the flexibility is a great advantage even if gaming at 2160p is mostly rather silly). But I would still expect it to be noticeable in desktop usage - though of course that requires some form of frame of reference, and is probably something a lot of users would never notice or think about. I sincerely doubt this has happened with higher refresh rate panels though, as 2160p panel tech fast enough to perform well above 60Hz is still relatively rare outside of TVs.

Of course there have been edge cases like first-gen 120Hz TVs that ran 120Hz at 1440p but only 60Hz at 2160p, but that was mainly due to the processors + inputs not being capable of more than 2160p60 - this was before HDMI 2.1, and TVs don't have displayport, which would have handled 2160p120 just fine. Given that DP is ubiquitous on anything but the cheapest monitors, I'd expect that type of reasoning to not be relevant there.

Are you sure that was a native resolution, and not downscaled? It's also very odd to support a lower resolution on DP than HDMI (except possibly HDMI 2.1).

Nope, will try to find the pics I took

Just like this weird no name monitor.
A 1440p 144hz monitor that can "switch" to 4k 60hz

Heh, that's a weird one. My guess would definitely be that it's a 1440p144 panel with a controller that can downscale a 2160p60 input (it likely doesn't have the bandwidth/processing power for 2160p144, might even be limited to DP1.2), but I guess there's a theoretical possibility of it being a 2160p panel with a weak-ass controller that doesn't match its capabilities. The latter sounds unlikely though, given how rare such panels are - 2160p144 monitors are pretty rare after all. The latter would also raise the question of how real that 144Hz refresh rate is - lowering the resolution won't affect pixel response times or the other physical properties of the panel, so are they just taking a slow 60Hz panel and flooding it with data, letting it blur itself into oblivion? I don't know enough about the relationship between the controller and panel to know if that would even be possible, but I guess it might be?
 
IIRC, even DP 1x is better than HDMI 1x, where you're lucky to get 2160p@30 Hz!
 
Got this 1060 6GB used (duh) from a friend:

Good point, it's for console support
4K60 is what this supports without hacking in refresh rates, which works well with my chromecast (and therefore, would with a console too)

My phillips 32" right next to it (1440p 144Hz VA) also works at 4k 60, but definitely appears scaled. It's fine on the chromecast but wrecks text in windows, so the gigabyte does *something* better than average and i've to finally find the full story behind that

To me, it looks like the 4k on the left.

I forgot the order i took the photos in, so i genuinely cant even tell myself
If i fix that softness issue (it's related to the scaling % windows sets) i'd not be able to tell at all

It would be kind of cool if they actually used 4k panels on those - I could see a market for third party display controllers "unlocking" the full potential of the panel :P Not for the faint of heart though.
 
So a little update.
The duel port broadcom NIC I ordered from China never came so I managed to get a refund and ordered a 4 port which was out of stock and replaced with a IBM which I hope my poweredge isn't going to argue with.

Ordered tons more esp boards and sensors for energy reading and some relays so when I build my server rack I can fit extraction fans.
And finally as a Xmas present for myself and my wife I'm finally starting to build a mesh network for the house and mainly the garden.
Screenshot_20211210-071806.png


Ordered some of these for the house and still undecided if I need anything faster than n300 for the garden so I need some more research.
Also picked up a second hand Poe switch and some spf links for cheap

Now I need to figure out how to put the omada controller in a lxc container on my proxmox server.

Sounds like RGBW LCD TVs! A good chance that it's fake 4K, where every certain pixel, is a white pixel! Do the math, with every certain pixel substituted with a white pixel, you won't get 4K!
If that's the case, also expect a retina-piercing nightmare!

If you missed the message before that (spread over a few pages) i forced both my 32" 1440p screens to 4K, one works amazing and one works as you'd expect (badly)

We've just been discussing that, since someone bought the same monitor i have, but the 4K version

Also more common on TVs is chroma subsampling, but neither of those are what we are talking about here.
