Panel Request: QD-OLED

Now that Samsung has revealed their QD-OLED panels, this technology seems to be the future of gaming monitors.

It has incredible HDR capability since its OLED with perfect blacks.
On top of that it has incredible peak brightness of ~1000 nits.
Its supposedly low burn-in also, with a 3 year warranty that includes burn-in.
The current panels also have high refresh rate in the ~175hz range.
Most of all, the pricing seems to be very reasonable, as a curved 34" 1440p monitor is “only” $1299.

If only there is a 4K variant, then that’ll easily grab customers looking for a better Eve Spectrum 4K and the $3000+ FALD crowd.

The current monitors seems to all have the same issues as the LG panel release, poor connectivity, no HDMI 2.1, etc.


I’m going to grab the first 4K, 144Hz QD-OLED that comes out. If it’s before Eve, well, goodbye glossy monitor!

do you acually think its worth the upgrade from the glossy eve monitor?

I would wait with it. The German magazine c‘t found a very annoying construction mistake in this panel: Alienware-Monitor mit QD-OLED im Test: Samsungs Display-Technik ist verkorkst | heise online (use for translation)

It basicaljy says this construction will never be able to construct correct colors at the edges because how the led are arranged. In a good quality assurance procedure this monitor should never be given a go.

Now I am able to deliver some English translated quotes (Alienware-Monitor mit QD-OLED im Test: Samsungs Display-Technik ist verkorkst | heise online):
“But unfortunately, the first look at the display already reveals a glaring weakness of the QD OLED: The AW3423DW displays all high-contrast edges in color. This starts with writing, continues with Windows windows and ends with 3D games, such as signs or one of the numerous skyscrapers in the action role-playing game “Cyberpunk 2077”, when you look against the sky. In the latter case, the display had something of a built-in shallow chromatic aberration - however, the effect is not as noticeable and annoying in moving games as it is in the static desktop. In the video above, you can see red color fringes on the trees in the action role-playing game “Horizon Forbidden West”, for example. Thus, the panel in its current form is a fundamentally messed up affair.

“The pixel arrangement is to blame: A pixel consists of three subpixels with the colors red, blue and green as usual, but they are arranged in a triangle instead of in a row. The red and blue subpixels are at the bottom, and only the green one is at the top center. The black gaps are quite large and every second subpixel row can consequently only display green, the other rows lack the green part.”

"In practice, this leads to the colorful edges: On bright surfaces on a dark background, horizontal edges are green at the top and purple-red at the bottom; on dark surfaces on a bright background, the QD OLED panel of the AW3423DW behaves the other way around accordingly. Darker on dark surfaces and lighter on light surfaces produce less noticeable blue tones. On vertical and angled edges, the color fringes depend more on the contrasts - everything from bright red, green, violet and blue is present (see mouse pointer in the picture above).

A look at the on-screen display (OSD) proves that the problem is not due to color subsampling, where the input device only sends reduced image information to the monitor. Even in the OSD without a connected player, the white text is colorful."

There is zero comparison between them.

The current 4K monitor has 16 dimming zones, QD-OLED 4K will have 8294400.
FALD tries to be a middle point with ~1000, but that costs >$3000.

OLED will always be superior to IPS if it can be bright enough and have reduced burn-in.

I suspect the conclusion that “every second subpixel row can consequently only display green, the other rows lack the green part” is probably wrong. According to the macro photos, each pixel has all three RGB components, just the subpixel arrangement is special — triangle-like instead of subpixels as vertical lines side by side. At low pixel density, this may theoretically result in somewhat noticeably fuzzy colors at sharp edges like in case of PenTile, but without PenTile.

This may be one of the main reasons why the monitors based on that panel are advertised as gaming-oriented.

On the other hand, on a higher pixel-density monitor such as 24-27″ 4K one, this effect would probably be much less noticeable.
