I know its 1440p, and in a laptop, but good to know the technology at leasts exists.
Come one 240hz C3!

I believe that laptop is using an OLED panel from Samsung. Samsung's QD-OLED TV's are also capable of 144Hz while LG's are capped at 120Hz. I wouldn't be surprised if Samsung beats LG to the punch with a 240Hz QD-OLED, although I really don't care who is first I just really want a 240Hz OLED monitor/TV period.

I've been waiting for a 42" 240hz OLED screen before doing any update on my PC, my six year old system has been waiting on monitor technology to make a major improvement, and a 4k 240hz OLED is what I would consider 'this is it'.

Smartphones had Amoled tech for years then the laptops get it. Desktop PCs are usually last because of the markup on smaller screens more profit on a smaller items. I hope I don't need to wait around for 3 years for a usable Desktop display that isn't a laptop.

That MSI 240hz laptop OLED has a pixel density (PPI) of around 190 and confined to a laptop!
I thought smaller OLEDs with high refresh rates due to heat was an issue. 42" LG panel PPI is measly 104 PPI. So smaller and much faster refresh rate OLEDs are feasible and still not available for PC monitors. Where PCs have by far the most capable and fastest graphics. Very disappointing where a TV is your best choice for a monitor and still not pushing the tech for a PC.MistaSparkul

LCD's have now pushed up to 500Hz in monitors while OLED's are just barely breaking into 240Hz in a laptop display. and a measely 138Hz on monitors. Pretty damn annoying.
Yep!

4k@138hz uses the same bandwidth as 1080p@552hz
I've been saying since forever LG should make their OLEDs work at 1080p with higher refresh rates. OLED at 120hz is already great, but 500hz OLED would absolutely BTFO any high refresh rate LCD. You could run 4k@138hz on the desktop and for casual gaming, then switch it over to 1080p@552hz for ultra competitive games.
It seems to me the only reason they capped at 120hz is becuase that's what TVs have been capped at and they haven't invested anything into going higher.

Meh I could care less they still haven't fixed the oleds frying their own screens to death from burn in lol

Just a reminder, the high hz isn't very meaningful without supplying it with frame rate averages or near minimums to match it.
144fpsHZ, 240fpsHz, 380fpsHz , 480fpsHz. Without the frame rates you aren't increasing the "number of animation cells in a flip book flipping faster", increasing more "dots plotting on a dotted line curve", for more smooth and more articulated movement.
You also aren't cutting the sample-and-hold blur (especially of the entire viewport while moving the FoV at speed) by any more than your frame rate in Hz does.
Even if you do supply frame rate averages / minimums near to the peak Hz of a very high Hz screen in a less demanding game like CS:Go for example - the nature of online gaming and online game server code, tick rates (all are poor but some are very, very poor), varying ping times, lag compensation and interpolated results, biased net code decisions by devs of different games, etc. means it's unlikely that you'd gain any competitive advantage as compared to playing (or testing) locally at a LAN party or LAN tournament or locally vs bots. You would cut the FoV movement blur by a lot more though which could help with aiming on the local end slightly.
==================================================================
Even if you set aside taking desktop/app real-estate and default interface sizes due to overall resolution limits into consideration, which is another big factor. . .
You really need to take it a step further and calculate the PPD. (pixels per degree, a measure of the percieved pixel density of a given resolution at distance)
You sit a lot closer to a laptop.
In order to get into better viewing angles of 44deg - 55 deg you'd have to be sitting 16.8" away (58 PPD, 44deg)) to 13" away (~ 47 PPD, 55deg) :
15.6" diagonal viewable 2560x1440 at 18" or 1.5' view distance is 41.4 deg viewing angle and is 61.9 PPD
15.6" diagonal viewable 2560x1440 at 24" or 2' view distance is 31.6 deg viewing angle (poor) and is 80.9 PPD
. . . . . . . . . . . . . . . . . . . . . . .
60 PPD , 64 deg viewing angle at 4k
48" 4k screen at ~ 33.5" away
42" 4k screen at ~ 29" away
80 PPD , 48 deg viewing angle at 4k
48" 4k screen at ~ 47" away
42" 4k screen at ~ 41" away
. . . . . . . . . .
The G9 ultrawide has a fixed curve which like a lens, has a focal point so you still have to sit a good distance away to be at the focal point. Neither a 42"/48" 16:9 OLED or a G9 are made for sitting at traditional desktop distances of 1.5' to 2'.

Text Fringing and Graphics Aliasing vs. PPD
==================================
Aside from the WOLED subpixel layout on LG OLEDS, which non-traditional sub sampling, greyscale subsampling, etc can help with a bit - -
A lot of people are also sitting way too close to large OLEDs, trying to make them work at a tradtitional "up against the wall like a bookshelf" or "upright piano with sheet music" type set up - which makes the pixel structure appear more granular and large (as well as the subpixels). It also provides a poor viewing angle for huds, pointers, notfiications and side text boxes, etc.
In my experience, (at default text and interface, menu, etc. sizes rather than scaling them up) no amount of text subsampling will be able to compensate enough on the desktop, or AA in games, once you dip below around ~ 60PPD. 60PPD looks decent but the viewing angle is less than optimal for HUDs, notifications, pointers, side chat boxes, etc.
As you get closer to the screen diagonal in view distance on 4k screens(e.g. nearing ~ 41" for a 42" 4k oled, ~ 47" for a 48" 4k oled), you end up with a better viewing angle in the 45deg to 55deg range and you get a tighter PPD nearing 80 PPD - that has to lean a bit less on: squeezing more out of subsampling methods, having to use heavier AA at performance cost.

- 60PPD to 80PPD on 42" 4k = 29.0" to ~ 41" view distance
- 60PPD to 80PPD on 48" 4k = 33.5" to ~ 48" view distance
- the focal point of a 1000R curvature screen is 39.37" view distance ~ 83PPD
Since it is curved, much like a lens it has a fixed focal point.
The curve is 1000R which means the focal point is 1000mm or 1 meter - which is a 39.37 inch viewing distance.
That is the distance it's fixed curvature makes as your viewpoint. Since it's not bendable you can't change this on the fly. If you sit at a different distance than this the curve isn't equidistant to you anymore.

Eh? Just dabbling.
Let see, my 27" 4K monitor, I wonder what PPD that has? Look rather good. Now my Vive Pro is OLED, 90 hz. Anyways do not follow anything dealing with OLED and smaller screen sizes dealing with PPD. I would think more is better, PPD and higher frequency as well.
Anyways where is my damn 4K 240hz 32" OLED monitor?
