Quoting: PikoloThe patent office can't find prior art for those? How? They're all issued since 2019! The only one that even seems novel is AUTOMATED PLAYER CONTROL TAKEOVER IN A VIDEO GAME, and I'd assume someone more familiar with MMORPGs can find an example. ROUTE NAVIGATION SYSTEM WITHIN A GAME APPLICATION ENVIRONMENT is bonkers - we've had animated navigation lines for decades!

USPTO no longer looks for prior art since at least a decade back, the new regime is that they only do very basic checks and then any violations such as prior art is up for a court to decide in a future lawsuit.

Quoting: ShmerlAbove one really looks confusing. I think you need all subpixels to be on to see the pattern.

The image I posted is from here:

https://tftcentral.co.uk/reviews/lg-27gr95qe-oled [External Link]

I see now what my issue was, I thought that your image was displaying the same pixel but with each subpixel on, checking the site you linked I now see that they purposely choose to light one subpixel per line. And that what was confused me since I know that the layout is horizontal and not vertical as the image suggested (when I looked at it too quickly).

And that's probably not the only ones out there.

Btw the LG one does not look correct, here is Rtings image of the same model:


The image above is with cleartype on, which is why there is the rainbow pattern.

Quoting: LoftyThat said, im no expert.. but would a subpixel change layout to accommodate the O(Oddball :P) LED layout for font's, (lets say on Gnome desktop) also improve the chromatic effect on video games running full screen that have nothing to do with Gnome or fonts ? Like when playing FMV for instance.

Do you mean changing the physical subpixel layout, or software like cleartype?

i guess what im trying to understand here is, does changing the subpixel layout in software fix the chromatic abberation as shown in the videos i linked where it not only affects text but actually more obviously to my eye the in game graphics.
Such as the still shot from 'horizon chase turbo' where if you look at the wheel you can see the LCD is how the image was probably drawn by the artist and how the OLED has additional chromatic abberation ( an effect i almost always disable in game).

I mean, im sure its not visible on a small screen like a steam deck as that is also at 10x zoom, in fact it's probably no biggie on a monitor either. But some people do seem to notice and have returned their OLED.

quite sure that anti aliasing for graphics could fix that just as it does for text, don't think that there is a single anti alias in existence that takes it into account though, could be a great idea for some one to play around with.

That is indeed an outlier that explains what is seen in the video linked by Lofty. Looks to be the QD-OLED pattern. Compare that with the WOLED pattern that is on my LG that is just RWBG in that order in straight horizontal pattern quite similar to the old CRT TV or the modern LCD pattern (with the exception of the White pixel).

interesting. the old CRT did spring to mind when looking at that image.

So it seems it does depend on the particular subpixel OLED layout as to how much fringing/abberation or perceived softness is visible. The problem is that, it's not likely a regular consumer would be researching into subpixel layouts when choosing a screen whereas most LCD are just plain RGB and work better for desktop font rendering at least right now on Linux.

That is because the CRT layout looks pure chaos but if you look closer you see that it simply is RGB in that order horizontally, what makes it look more complicated is that the pattern doesn't start at the same position on every line, meanwhile the QD-OLED one have some of the pixels above a row of some of the pixels so to speak.

That layout clearly have a connection with how people who experience the effect experiences it, however just like Shmerl mentioned about the resolution also have a high effect here, a 720P screen like the one on the Deck simply have such a low resolution that the layout is more visible.

What everyone can try just for fun is to create a single pixel image (here we create a red pixel):
 
convert xc:red image.png

And then open it in a image viewer, make that full screen and make sure that zoom is 100%, then you can see just how large or small a single pixel is on your screen.

OR for more fun make a 3 pixel RGB:

 
convert xc:red image.png
convert image.png xc:green +append image.png
convert image.png xc:blue +append image.png

On some screens, if you zoom in the pixels will not look like they are in a straight line due to the subpixel layout

Quoting: WorMzyStill not sure what advantages this gives over PulseAudio, but it seems to be pretty embedded in the Arch package ecosystem (it's been present on my system as an unconfigured dependency for something else since mid-2018):

$ pactree -rs pipewire | wc -l  
2409
$ pactree -rs pulseaudio | wc -l
105

Guess it's time to take a look and see what all the excitement is about.

The biggest advantage is that it is a unified solution for both low latency music creators and normal desktop + gaming. Since it also uses less advanced functionality of the underlying ALSA drivers there are some hardware that works better in PW than in PA (since the ALSA drivers for that hw is bad).

Quoting: F.UltraOne is not sharper or softer than the other, it's just that algorithms like ClearType are designed for one of them but not all of them when adding anti aliasing tricks to fake a higher resolution for text than what the screen can produce natively. A single pixel is as sharp on any of these, so this is only down to algos that are trying to increase the sharpness of text.

Now that the dust has settled on the OLED release there is some more detailed content describing what i believe to be the issue some OLED monitor owners have reported across the net.

8.30 - 11.30 timestamp

a few things to note. i do understand most people cannot see this 'chromatic aberration' like effect, especially in these circumstances with the deck and probably not from a few meters whilst sat on a couch watching a TV... but it exists. And im fairly sure given the time taken to select the deck's new screen, valve could have fixed this if possible in software (and idk, maybe they can). Personally having owned a cheapo DLP projector that had a wonky color wheel it looks like the same thing. It's why i mentioned about the 'softness' that others noticed. i imagine it's very minimal but some people really do seem to notice.

Of course response time and black level are perfect vs an LCD (although there are some really quick LCD's now that easily hit their response time window with minimal blur) So this isn't a gripe against OLED tech, anything that improves the visual experience for the end user is welcome. OLED is thirsty on larger screens & has an oddball subpixel layout, other than that it's a great technology and il no doubt own one, one day in the right specifications.

whole video : https://youtu.be/nTRIVZPqUK4 [External Link]

Well calling it oddball is simple "hey I'm accustomed to the layout of LCD:s". Every single subpixel format in use is oddball since the only one that should not be would be to have no subpixel layout and instead a single pixel able to change the color and not having each pixel really be 3 or 4 subpixels.

Chromatic aberration exists on LCD:s as well which is the reason why Cleartype was created in the first place. But yes some people tend to see it more on OLED:s for some reason, Monitors Unboxed being one of the, and I don't doubt any of them, it's just ofc hard for me that doesn't see it to really understand what they talk about since, well I don't see it even though I site closer to my 45" than HUB/MUB does with his 34" so therefore my initial take is that somehow Windows makes it worse (since he is on Windows and I'm not).

Also if cleartype was made to "fix" the subpixel format of LCD:s then it should be possible to create a cleartype algo to make it work with the other formats as well (ofc nothing is guaranteed).

In any case since I don't see it I simply see myself as lucky :)

Quoting: kuhpunktDoes anybody have any idea if Valve is still working on a solution to this problem? All this ffmpeg stuff. It's great that GE-Proton exists, but it would be nice if you could just rely on vanilla Proton.

Isn't their solution basically mechanical, going through games one at a time redoing video files as something usable?

Is this one of those things where it matters if the file format is still patented?

quite sure it's a patent issue yes, Valve would be a nice juicy target for any patent troll.
