[@monitorsunboxed]

I should note here the longer DisplayPort cables I showed in this video I couldn't even test with this monitor as they were normal DP cables - so they might not work, and probably won't work because they're not officially DP80 certified by VESA. Which is another layer of confusion because cables can be DP2.1 certified but not certified for the full bandwidth requirements as DP2.1 has multiple bandwidth specs. I bought them to see whether they'd work but ultimately because the W7800 doesn't support UHBR20 over full sized DP I was unable to check their advertised claims EDIT: As several commenters have pointed out, the longest certified DP80 cables are 1.2m long, which further restricts cable compatibility and usability. DP1.4 monitors can easily use 5m cables but if you want to go with DP2.1 UHBR20 you'll be stuck with these short cables by the sounds of things, at least for now

[@wsjudd]

Was going to say, Gigabyte's PR told me that longer DP80 cables aren't yet available!

[@Phixiso]

The longest officially certified UHBR20 DP2.1 cable is 1.5m lol... Worse than the HDMI cable they shipped the LG27GR95QE with, which caused the monitor to turn black randomly until you changed it

In regards to the 1m DP2.1 cable, at the moment, the longest CERTIFIED DP2.1 cable is only 1.2m long (Club3D). AFAIK, there isn't a longer DP2.1 certified cable yet that can be guaranteed to work. Perhaps in the future, there will be longer cables when they improve the standards for DP2.1. You can find the list of certified DP2.1 cables on the VESA Displayport site.

[@interceptor001]

I love that you did research reading threw papers! Thx for doing so. I was so worried to get the AW3225QF because of DSC but it is so much cheaper.

[@0perativeX]

The AW3225QF has been reported on the NVidia forums to have VRR screen flicker issues. It also has an active fan inside and curved (which isn't great for viewing angles). For those 3 reasons I avoided it and went with the FO32U2P. Zero issues so far, so i'm pleased I chose it over the AW one. Plus its a bit more futureproof in that it supports proper DP2.1 UHBR20. No doubt the Nvidia 50XX series cards and AMD's new offerings will also sport at least one DP 2.1 UHBR20 connector.

[@interceptor001]

@@0perativeX I get the AW3225QF because of its slight curve. The FO32U2P is not officially certified by Nvidia to be "G-Sync Compatible" whereas the AW3225QF is. This leads me to the hope that Alienware can provide a firmware update to improve VRR like msi already did. Also, it is not supported yet by the driver. The FAN does not bother me at all, if it helps with OLEDs to keep them cooler the better. Also, it is 330€ cheaper and as OLED is yet not that bright I hope that 2025/2026 panels will be brighter so I will upgrade non the less.

[@StudyWithNika]

Amazing content ❤

[@erictayet]

Thanks Tim! This is EXACTLY why I have yet to buy this monitor. Waiting for your review. Great explanation on DP2.1 UHBR20. You just confirmed what I thought about future-proofing. In Singapore, the prices of all the latest QD-OLED are quite similar so if the FO32U2P has similar performance as the MSI, then I would buy the Gigabyte. I keep my monitors for a long time and I go thru 2-3 GPUs during the life of my monitors across 4-5 generations of GPU. Meaning I change monitor every 5-6 years. Anyway, you wouldn't notice ANY difference in YT vid to compare DP2.1 & DP1.4 because the footage are compressed and max out at 4K60. Text scrolling wouldn't show as well but UFO test will be interesting. I guess only hi-res RAW pictures & low compression HDR10-12 videos will show some difference. From what I read, DSC works by converting RGB signals to a colour space that represent what our eyes can detect, then from there decrease the bit depth of the chroma channels from 10 bits to 8 or 6 bits. The monitor will then interpolate adjacent pixels' chroma channels so colour gradients will not exhibit any banding issues due to drop in bit depth, hence dynamic range. Pictures that may exhibit issues with DSC may be high contrast photos of leaves or grass against bright background, and brightly lit fur/feather. But I must admit that at such high DPI, most people will not be able to spot it. This is probably more obvious with 50"+ displays. Will be interesting to see if high refresh rates will affect grey-to-grey response time. Looking forward to full review! Edit: Pairing this with the 7900XTX so I hope a good 2M DP2.1 cable will work. At worst, maybe do what Linus did and buy an active optical DP2.1 cable but those are REALLY expensive!

[@cromefire_]

DP2.1 really is one of these things where you go: Yeah cool it's there I'll take it, but it'll not sell a device purely based on that. My monitor has been working pretty much flawlessly with DSC, but I also have an AMD GPU.

[@BenvolioG18]

Great video as always. I consider myself an informed buyer but videos like this are eye opening. I was unaware that DP 2.1 had different standards for bandwidth, good to know that UHBR20 is the one to look for. I personally have only had one issue with DSC which was on my newly purchased LG 32GS95UE. I was using DP 1.4 with the monitor's onboard speakers but when launching Fallout 76, the game would not output to the speakers. If I cranked the resolution down to 2560x1440 at 120hz, the speakers would work fine which I assume has something to do with DSC as the game is launching. I ended up switching over to HDMI 2.1 and locked the game at 139FPS due to a physics issue; that combination seems to have fixed the DSC issue as the speakers work fine now. I am wondering if 4k at 139FPS is just under the bandwith requirement for DSC to activate. In a perfect world, I'd prefer to use DP 2.1/UHBR20 but HDMI 2.1 seems to fill the gap well enough.

[@DabiOW]

Another two reasons people dont want to use DSC is faster alt-tabbing, and potentially lower latency. Testing that would be interesting.

I ordered the Aorus FO32U2P. And I didn't really do that for DP2.1, though that is one of the few reasons I bought it. The main reason I bought it, is that it was one of the few QD-OLEDs I could actually get since everything else is out of stock. Also where I live the price difference between the DP2.1 and the cheaper 1.4 version wasn't big enough to warrant going for the cheaper one, as they already cost a lot of money out of the gate.

[@houssamalucad753]

Also don't forget that it's easy to make an OSD toggle to activate and deactivate DSC, Asus does it, and I think one of the other manufacturers too, it would allow you to run DSC on lower quality cables, and without it on good quality ones (in the case of the Asus it locks you to 120hz without it since it doens't support dp2.1)

What an absurd take. Why would you want something to not work when can most probably work in a different mode, especially in the default configuration.

[@AH-video]

great work tim very well explained

[@benjaminchung991]

The Displayport 2.1 standard now supports link training, so it's theoretically possible to detect a degraded cable and revert with the source. I think it just isn't implemented in current PHYs.

[@benjaminchung991]

Following up on this, based on the DisplayPort RX Subsystem LogiCORE IP Product Guide (PG233) from Xilinx which implements a DP 2.1 RX for FPGAs, the GPU/TX is responsible for determining the bandwidth after the link training period. The RX side can suggest a bandwidth in advance of link training but the GPU is the ultimate arbiter of what bandwidth is actually targeted for the communication. Thus, I think that the problem here is actually on AMD's side in not using the training results to determine bandwidth rather than on the monitor.

[@rinoan1]

Just the video I was hoping for! With that said, I sort of feel that the DSC-part was a bit underwhelming. For instance, DSC is a lossy compression since it removes data. This will lead to compression artifacts. There is also the error-rate for the reconstruction of the removed data. On top of that, DSC does not use previous frame to improve compression quality like other algorithms. This means that from frame-to-frame, there will always be artifacts. When DSC are at its worst, is at very sudden changes from frame-to-frame. An explosion in a video-game or a gun muzzle flash, for example. Latency is a none issue. It will proximate to the same latency as running with 4:2:2 subsampling (has to reconstruct to RGB before the monitor can use it). With all that said, one could say that viewing a image in png vs jpg is similar to native vs DSC. The differences are there (for every frame), but does those differences matter? I think you should be able to showcase these difference between a DP 1.4 graphic card and a DP 2.1 UHBR 20 graphic card with slowmotioning them side by side during an explosion in a video game. EDIT: reference with sample: forums.blurbusters.com/viewtopic.php?t=12235

Finally, a proper 10 bit monitor. I notice that Blackmagic Design make DeckLink monitor cards up to 12 bit, with SDI/HDMI 2.0a, REC 2020, 4:4:4 colour space, up to 8K. Not sure if they will work with this monitor though, or if you could play games with them. Great for editing though.

[@KiltedCritic]

I was concerned at my Alienware AW3423DWF stepping down to 8-bit signal to get the full 165Hz, great to see that question answered and it's basically no difference except in math.

[@tresnugget]

That's 8 bit + FRC, not DSC. If it had DSC it would run 10 bit all the way to 165 hz. The AW3423DW/F doesn't support DSC. Most (if any) people probably can't tell the difference between true 10 bit and 8 bit + FRC but we are talking about 2 different things although from my understanding they're both used to save bandwidth.

[@arech1778]

For me, a VR user, DP2.1 is a must, so I hope GPU makers will use it with the highest possible bandwidth

[@Weissrolf]

DSC also usually disables MultiPlaneOverlay (MPO) on the "two GPU heads used" connections.

[@chairs-dimension]

The cable provided with the monitor in the box is likely for daisy chaining the display to another monitor rather than for plugging it into your PC

[@begna112]

I don't think so. The mini DP out is only via a full size DP port and the mini is only in. Both the mini in and the cable are full UHBR20.

[@kissu_io]

I spent quite some hours trying to understand all the limits on Wikipedia and was worried that I would need to have a 2.1. But no GPU no supporting it was quite crazy to me. Turns out I can run my future 240Hz 4K OLED with DSC. That's definitely not a deal breaker then. Especially if you support the fact that the compression is not too awful. Thanks sir for the deep dive.

So only when using not native resolution it doesn't scale as well with DSC enabled. That is apart in R6 siege when looking at saran wrapped crates for example. Outside of that can't see a difference. This is on the MSI MPG 321URX

[@AnimeUniverseDE]

A bit unrelated but there's been a recent discovery that QD OLEDs have worse PQ EOTF tracking in the lower portion if they are "warm", meaning after being on for like 40min. This would mean shadow detail is severely raised by 300%, whereas at startup everything appears fine. Can you test this as well?

[@houssamalucad753]

interesting, can you link the source please?

[@monitorsunboxed]

All of the testing seen on this channel so far has been when monitors have been warmed up for hours, and I've seen quite a few monitors with good lower portion tracking when warm. So not sure where that's come from

[@AnimeUniverseDE]

@@monitorsunboxed this info comes from Dylan Raga, who is a display reviewer over at XDADevelopers. He shared his findings in a HDR discord community called "HDR Den". Others were able to corroborate his results. I don't think he has made an article about this yet, because he also tries to understand the issue further. This problem seems to affect gen1/2 of QD OLED as well

[@AnimeUniverseDE]

​@@monitorsunboxed Dylan Raga has published his review of the AW3225QF on XDA now, and also included a section about this problem with pictures

[@STKReacts]

I am still in my return window for my Alienware 32 inch 4k oled…..I do plan on getting a 50 series on day one release(I live next to micro center)….might return it tbh

[@KursaalFlyer]

Love the vids and analysis by how do you remember which bit of kit you are talking about with these huge often meaningless model numbers. Isn’t it time industry to got a grip.

[@StaySic4Ever]

Shame rest of new OLED monitors didn't come with DP2.1 would've been nice. Though expected to see on future wave of monitors. Just today there was a 4K 1000Hz demo monitor Blur Busters teased. I'd expect 1080p 1000Hz to hit as a next jump along with DFR mode for 4K monitors. Bandwidth is there.

[@vicariousvindicator7545]

Also, with DSC as it is, whenever you use a monitor that requires DSC to get all your shiny features (res, refresh, bit depth, etc..) you're effectively limiting the amount of monitors you can connect to your GPU because DSC will use more than one display head to drive that screen. I am typing this on the above mentioned monitor in this discussion and I bought it in anticipation of full spec DP 2.1 coming out with the next generation of GPUs (nVidia 5000 - series, AMD - 9000 series) so that I could purchase 2 more of these monitors and connect them to the same GPU w/o to install a secondary GPU into my system and halving my PCIE lanes (z790 here).

[@amoghshanbhag4304]

Hey Firstly love your videos helped me a lot finalize my monitor. I went for AW3225QF. Coming to my question: I want to use my monitor with dp port to keep my hdmi ports open. For future console setup. Right now I have laptop with full thunderbolt 4 functionality. Which cable/adapter/dock should I got for to get the full 4k@240hz from my monitor. I have a 4080 175w laptop

[@michaelfrizz6925]

And I use the same DP 1.4 cable I used for my 1440p monitor there's no issues at all

[@John-mn3iu]

The fact they haven’t even invented a VESA certified DP80 cable longer than 1.5m boggles my mind. I’m sure we’ll have 2m out by the time the 5090 drops though. I trust NVIDIA will support DP 2.1 too

[@MultiNastyNate]

Your most anticipated video of the year for me

[@RantGG]

wish we had a system power consumption comparison between DSC and non DSC, idle clocks etc.

[@petrnechvatal4251]

Is there some overhead from having to compress and decompress the signal? Could it introduce some amount of extra latency?

[@tongwang653]

Thanks for confirming my thoughts that DSC really doesn't degrade visual quality in any perceptible sense. I like that movie compression example. Tbh I cannot tell any difference between a full Bluray and an encode at half the size, even with pausing and staring on my 83 in TV. Feeling more reassured with my new AW3225QF now.

[@worldwanderingfisherman2166]

He said researches saw degradation in image sometimes, so is not visually lossless.

[@markjacobs1086]

​@worldwanderingfisherman2166 It's very much like modern lossy audio compression. It throws out data that can either be reconstructed from the other data (usually at reduced accuracy) or an imperfect human organ isn't sensitive to (much like chroma subsampling which focuses on the most important aspect of an image in relation to the human eye: luminance).

[@Cuthalu]

Encodes aren't encoded on the fly while you watch them, but DSC is applied on the fly. It adds another level of potential issues.

[@hbjigcc]

Another limit of using DSC is multimonitor support. You're limited to 2 monitors in this configuration. From Nvidia: When a display is connected to the GPU and is set to DSC mode, the GPU may use two internal heads to drive the display when the pixel rate needed to drive the display mode exceeds the GPU’s single head limit. This may affect your display topology when using multiple monitors. For example if two displays with support for DSC are connected to a single GeForce GPU, all 4 internal heads will be utilized and you will not be able to use a third monitor with the GPU at the same time.

[@citizencr4o]

8:25 you need to put an edit into the video, one of those text boxes showing the correction here. I could not understand why Gigabyte would ever include such a tiny cable and then later you release a whole video explaining that those specific high-end DP cables only come in 1.2 meter length. I'm happy you released a video but please edit this one as well to include the correction.

[@amsterdampyro7182]

@monitorsunboxed , which monitor you prefer the Asus PG32UCDM or the Fo32u2P?

[@BubbaBearsFriend]

I had similar issues with the first DCI 4K 60Hz monitor I purchased since only the newest (at the time) DP1.2 cables could support the 60Hz refresh rate and all my existing cables were 1.0 which wouldn't. I had to force the monitor to not use DP 1.2 in the menu to use the DP 1.0 cables.

[@andred.2335]

what aboubt dsc and the performance/latency side of things? as some compute power for compressing/decompressing is needed, maybe there is a slight disadvantage?

[@AthamAldecua]

This is a very good monitor, I don't regret getting it. The short DP cable is annoying though.

[@George-um2vc]

That's great man! looks really good! If you disable DSC, can you use Nvidia's DSR/DLDSR feature using a DP 1.4 cable? that's the make or break question for me with this monitor...would really appreciate if you could confirm, god bless.

[@noobahoi]

Nice video. Still, I would want 4k@240Hz without DSC. So I wait a little bit until it's widely available.

[@Rez_nick]

I hope the full review drops soon. My one got delivered today still haven't opened the box

[@0perativeX]

Got mine yesterday, it's a fantastic display, you'll love it :)

[@miikasuominen3845]

As a matter of fact, every 120Hz capable TV should also have it... Just because of the situation of HDMI2.1 on Linux... And even if there would not be that situation, it should still be there!

[@williamdouglas8040]

DisplayPort daisy-chaining will require twice the bandwidth. Daisy-chaining the DisplayPort signal is useful if using the first monitor as a KVM and you want to connect a laptop to multiple monitors using a single cable. Of course, still waiting on those laptops with DisplayPort 2.1. FYI, might want to test the KVM and daisy-chain capability in the full monitor review.

[@De-M-oN]

Friday it will arrive me too 😍😍

[@liaminwales]

Iv seen a few posts about HDMI problems, people just assume it's the GPU or Display (which ever is the newest of the two). No one thinks it's the cable, we are not used to cables being the problem.

[@drainier2618]

There's one thing you didn't mention, which I'm quite sad about: Black screens when going in and out of Fullscreen games. In my opinion, it is the biggest down-side of DSC. On some monitors it's only about a second, but I've tested ones where the black screens last more than 5 seconds. When trying to Alt+Tab out of a game quickly to check something, or answer a voice call, etc, it can really be a big annoyance. Secondly, I've also read reports on the Blurbusters forum of people experiencing a "heavy mouse effect" when using DSC. This is probably negligible for most people, but for people who are very into competitive gaming, it is something to consider.

[@charliegrech2026]

This is true but its specific to Nvidia, theyve known for over a year and dont care sadly

[@drainier2618]

What you’re saying is true but I fail to see the point you’re trying to make. In the video he DOES talk about NVidia specific issues, namely missed features etc. He dedicates a section of the video to talk about issues arising from the use of DSC, and in my opinion forgets the most annoying one. NVidia has the obviously bigger market share of GPU’s, and displays that require the use of DSC are most often used for gaming, meaning NVidia specific issues, are issues for the majority of people using DSC.

[@MrRotch61]

Integer Scaling is one of the features that you can't use with DSC enabled, which is such a shame because I was really looking forward to playing older titles that don't scale well at 4K, with 4K being the perfect resolution to integer scale 1080p titles. I got the FO32U2P to future proof myself, but yeah, if Nvidia could actually just upgrade their latest drivers to enable Integer Scaling, I would appreciate that a WHOLE lot more than waiting for potential DP2.1 80Gbps GPU's to hit the market.

[@lil----lil]

Compression will always reduce quality no matter how indiscernible. There's no way around it. From MP3 to MP4, you can both "hear" _and_ "see" the difference that's WHY DP 2.1 all the way for me and this _is_ the monitor that I will be using to pair with my RTX 5090 come later this year.

[@houssamalucad753]

I have a question Tim, for the 24" tactical mode, is 1080p the only allowed resolution? because that would be pretty stupid not to allow 1to1 pixel mapping (around 1800p) like the Asus model does. 1080 scaled with a non integer scaler will be very blurry and render the 24" mode (one of the only 2 differentiating features of this monitor) completely useless.
