MSI, Asus and Samsung are announcing new 27-inch 4K models with '4th gen' QD-OLED panels but they're not a huge step forward

pcgamer.com:

With CES 2025 just around the corner, multiple gaming monitor brands are unleashing their wares for the new year. We've already seen some 500+ Hz OLED panels. Next up is a new generation of 4K 27-inch OLEDs.

Thus far, the 4K OLEDs we've already seen are all 32-inch models. That applies to monitors based on both LG WOLED panel tech and Samsung QD-OLED. These new 27-inch models are all based on what's being billed as '4th Gen' Samsung QD-OLED technology.

However, do not get too excited by that '4th Gen' label. The new 27-inch 4K Samsung panel does not appear to move the game on for metrics like brightness. Instead, it's more of a shrinking of Samsung's existing 3rd Gen 32-inch 4K panel, like that in the MSI MPG 321URX, down to 27 inches.

That brings with it clear benefits in terms of pixel density. Existing 32-inch 4K panels come in just under 140 pixels per inch. These new monitors will be a little over 160 (actually 166 DPI due to the panel size coming in at 26/5 inches).

That should put to bed concerns over font rendering with the QD-OLED tech and its triangular pixel substructure (which is retained for these 27-inch panels). Font rendering was already pretty good thanks to the pixel density of 32-inch models. At 4K and 27-inch, it should be a total non issue.

The benefit of the pixel density for gaming is more debatable. Do many gamers look at a 32-inch 4K panel in-game and think it's nice but a little bit blocky? In practice, the visual benefit in terms of sharpness and in-game image detail going from 32-inch 4K to 27-inch 4K is marginal. But the smaller panel size and the reduced immersion that brings is arguably more obvious.

With all that in mind, who are the players in this new market? Among the first out of the gate is the Asus Swift OLED PG27UCDM. It packs the new Samsung panel running at 240 Hz, plus DisplayPort 2.1a (up to 80Gbps).
