ASUS has published the product page for its upcoming ROG Swift OLED PG27UCDM gaming monitor, which will go head to head with the MSI MPG272URX on which will hit retail as the first 27-inch 4K 240 Hz display. The PG27UCDM sports a 26.5-inch panel using what ASUS refers to as 4th gen QD-OLED technology, which the company claims offer longer lifespan compared to previous generations of OLED panels. The panel sports typical OLED features such as a 0.03 ms response time, a peak brightness of 1,000 cd/m², 99 percent DCI-P3 colour space coverage and VESA DisplayHDR 400 True Black. The display also supports AMD FreeSync Premium Pro and NVIDIA G-Sync compatible, as well as a host of ASUS specific gaming features such as ELMB, GameFast Input Technology, Shadow Bost and a DisplayWidget.

Inputs consist of a DisplayPort 2.1 port with UHBR20 (80 Gbps) support, a USB Type-C with DP-Alt mode and USB PD up to 90 W and a pair of HDMI 2.1 ports. There's also a three port USB 3.2 Gen 1 (5 Gbps) USB hub with what we presume is a USB Type-B input and a headphone jack. The reason for the presumed USB Type-B input, is that the specs claim KVM support and this would only be possible if there was a USB input of some kind, but this isn't mentioned in the tech specs. The stand is your typical higher-end model with tilt, swivel, pivot and height adjustment, as well as ASUS' Aura Sync lighting and a tripod mount at the top. ASUS claims a power consumption of around 80 Watts, although this doesn't include USB PD. A big plus is that ASUS will bundle a DisplayPort 2.1 DP80 cable in the box, something for example Sony decided not to include with their INZONE M9 II which launched in September last year. There's no word on pricing for the ROG Swift OLED PG27UCDM, but expect it to be on the expensive side of US$1,000.

All the wailing, crying and gnashing of teeth about the new video cards and their prices, the Display Port 2.1 seems to get lost in the tears and bowed heads.
My monitor supports DP2.1 therefore my new video card should support DP 2.1. Henceforth the RTX5090 is justified.
Please, wail away and carry on Team Sad.

I own an FO32U2P and honestly? not needing to use DSC is far from the top of my priority list for next generation. I wouldn't mind not needing to use it by the time this screen never turns on again

Since I'm about to buy the PG32UCDM, but it ‘only’ has DP1.4 so far (presumably an updated model coming soon?), I'm wondering what advantages DP2.1 should have with an RTX5090. Isn't HDMI2.1 completely sufficient?

costs more than the 32" MSI one we have but now it is inferior at 27" though

really needs to drop in price to $700 or less or 4k at 27" is not that interesting

This ROG SWIFT 360Hz is a few years old now but has been rock solid. It never saw any gaming but when I saw how the stand could be used as a clamp for my mobile computer desk sealed the deal for me.

I'm sure that made sense to you. me? not so much...

ill try to break it down for you.
DSC or display stream compression technically (what we use with older DP) does compress the signal data for us to be able to enjoy high data-rate video, but in reality its impact is so invisibly low, that nobody is in a real rush to provide DP2.1 capabilities to consumer grade graphics cards even in the 4K240 era. There's no rush and no push to get consumer GPUs out the door with DP 2.1 arrays because of it.

Finally an actual announcement in the 27" 4K HRR OLED category but with no expected launch date. Stop messing with my upgrade itch damnit.

Proximity sensor for burn-in prevention is something I...think I have heard of but can't recall which 27" 1440p or 32" 4K models have it.
Not that it matters this time. I will just lump all desktop shortcuts at my other monitor so that there will be no desktop layout got messed up when I physically turn off whatever new monitor I get.

I guess this exact model will be a "well, I'm the best in this category" model to justify a USD900~1000 launch price. That MSI 32" model (I'm assuming MSI MAG 321UP at USD800 launch price) is very potato in terms of functions, and can do only 165Hz, so it should not be compared to this one too closely.

Oh crap there's already a review here. Haven't watched it completely, just to lump it here.

You do realize that every new card released in 2025 will likely support 2.1 UHBR20 right?
It is not some magical thing Nvidia came up with for their 5090...

How about running without DSC and it's related issues?
HDMI 2.1 is 48Gbps and while it's higher bandwidth than DP 1.4a it's less than DP 2.1 UHBR 13.5, much less UHBR20.
HDMI 2.2 is in the works but dont expect this until 2028 maybe.

I'll let you know when it gets setup and you can come fly the sim.

I'd rather get the Sony M10S, much sleeker design.

This kiddo toy look ASUS goes with totally doesn't do it for me.

HDMI 2.1 48Gbps and DP 2.1 40Gbps are basically on par since they use 2 different encoding schemes.
16b/18b on the HDMI 2.1, leads to 41.89Gbps of effective bandwidth.
128b/132b on the DP 2.1 (all three standards), leads to 38.69Gbps for the UHBR10 version.

4k240hz 10bit RGB requires 68.56Gbps. If you apply the minimal DSC compression (16bit/pixel), bandwidth decreases to 36.56Gbps.
So, DP 2.1 UHBR10 (+UHBR13.5) and HDMI 2.1 48Gbps give you the same visual result.

How can it be Dolby Vision (see 3d pic) and only VESA DisplayHDR TB 400 at the same time?
No VESA DisplayHDR 600.
What about HDR10+?

There isn't any relationship between Vesa certifications and DV. Being an oled, Vesa only refers the minimum luminance level on a 10% windows.
It's 1000nits peak brightness.
No VESA DisplayHDR 600.
That's an LCD standard. It doesn't meet the DisplayHDR True Black 600 requirements i guess for the full screen sustained brightness (350nits on the True Black 600 certification).
What about HDR10+?
Well.. Do you really want an answer?

Are you running windows with any scaling? Seems like shit would be tiny
Sure, 125%, but that's perfect.
No scaling when gaming obviously.

My laptop with 2880x1800 resolution on a 14-inch display is much harder to work with, even with scaling.
