The ASUS ROG Swift OLED PG34WCDN wins because it is the rare ultrawide that refuses to compromise. RTINGS, in their lab testing, named it the best ultrawide monitor overall, pointing to a QD-OLED panel that delivers perfect blacks, vivid color, and the kind of HDR that VA and IPS screens simply cannot match.
Then there is the speed. At 360Hz with near-instant OLED response, it is among the fastest ultrawides anyone has tested, so competitive gaming feels as sharp as the picture looks. The 3440x1440 resolution at roughly 110 PPI gives a comfortable, spacious workspace for everyday productivity too.
It is a premium buy near $1,300, and it leans gaming-first rather than dock-everything. But for a single screen that handles fast shooters, HDR movies, and a workday equally well, the reviewer consensus puts it at the top.
What It Won't Do
It is gaming-first in its connectivity. There is a USB hub but no USB-C power delivery or KVM, so it will not replace a laptop dock the way the Dell UltraSharp does. And while 3440x1440 is sharp, it does not reach the pixel density of a 5K2K panel like LG's 45-inch.
The MSI MPG 341CQPX proves you no longer have to spend four figures for OLED. It pairs the same class of QD-OLED panel as the flagships with a 240Hz refresh, and reviewers including PCWorld single it out as the value pick of the category at around $800.
What pushes it past the cheaper budget options is versatility. It includes USB-C with power delivery and a built-in KVM, so it doubles as a one-cable dock for a work laptop, something even our Best Overall pick lacks. For most buyers, that combination of true OLED image quality and genuine desk utility is the smartest money in the category.
The gap to the flagships is real but narrow: 240Hz instead of 360Hz, and a standard size rather than a giant canvas. For hundreds less, that is an easy trade.
What It Won't Do
Its 240Hz refresh trails the 360Hz flagships, so the most competitive players will notice the difference. The resolution is 3440x1440 rather than 5K2K, and the size and curve are conventional rather than the immersive 45-inch experience some buyers chase.
