AMD RDNA 3 GPUs to Support DisplayPort 2.0 UHBR 20 Standard
AMD's upcoming Radeon RX 7000 series of graphics cards based on the RDNA 3 architecture are supposed to feature next-generation protocols all over the board. Today, according to a patch committed to the Linux kernel, we have information about display output choices AMD will present to consumers in the upcoming products. According to a Twitter user @Kepler_L2, who discovered this patch, we know that AMD will bundle DisplayPort 2.0 technology with UHBR 20 transmission mode. The UHBR 20 standard can provide a maximum of 80 Gbps bi-directional bandwidth, representing the highest bandwidth in a display output connector currently available. With this technology, a sample RDNA 3 GPU could display 16K resolution with Display Stream Compression, 10K without compression, or two 8K HDR screens running at 120 Hz refresh rate. All of this will be handled by Display Controller Next (DCN) engine for media.
The availability of DisplayPort 2.0 capable monitors is a story of its own. VESA noted that they should come at the end of 2021; however, they got delayed due to the lack of devices supporting this output. Having AMD's RDNA 3 cards as the newest product to support these monitors, we would likely see the market adapt to demand and few available products as the transition to the latest standard is in the process.

with TSMC saying a 20% price increase and 15%?? The year before I’m guessing these will be 35% more msrp over last gen???
Technically its a 4K 144hz capable panel. It just cant do both because somehow, SOMEHOW DP and HDMI tech are just that far behind the panel tech :/ 16:10 is long dead
16:9 was chosen as the defacto standard long ago - i've lived through 4:3, 5:4, 16:10 and 16:9 on desktops - and when games all screw over anyone using anything other than 16:9, i'll happily stick to it.
From Vert- instead of Hor+, to outright blocking anything other than 16:9 any game with a competitive scene locks everyone to the one aspect ratio, or punishes you if you force the issue by reducing what you see. If you're in some niche market where you want an alternate, non-standard aspect ratio then go ahead and use it - but it's an old standard that just wont be easily available, and never will be again.
I really don't see the point in going beyond 4k resolution when it comes to home use(gaming, productivity, 3D apps, etc.). You eventually reach a point where you get diminishing returns from going higher & higher in resolution for screens that are going to be only a few feet away from your face. I honestly don't think multi-GPU is ever going to return; especially when it comes to the newer generation of power-hungry GPUs. I currently have a 1600-watt PSU for my two GPUs, and given the current trend, we'll be needing 2,000+ watt PSUs to run a multi-GPU system for rendering. Imo, the only real use I see for ultra-wide monitors is for running flight simulators or games that benefit from having a wider view.
Instead of adding more horizontal view, they're scaling it up to a higher 16:9 resolution and cropping the vertical... let me go find some of the example photos or videos, as some people understand it better from those
Spoiler tags for others to save the thread
Needless to say, it still boggles my mind how some people still want to use these kinds of monitors for everyday web surfing or office productivity. It would drive me crazy trying to work in Excel on one of those curved ultra-wides.
At least with that you still have 2560x1440 centered with bars on the sides, or if you use 2D software or PIP modes you can treat it as two seperate displays
Talk about necrophilia, eh? :D Anyway, yes. I am talking about pulse-width modulation.
It doesn't affect monitor or computer performance but it can scramble your eyes and brain if you are sensitive to this.
I remember those old Korean 1440p panels from like 2012-2014 had PWM flicker, and they did give me a headache.
Do you think OLED would give me a headache as well, or is the PWM flicker different?
And no, I don't have a bias here. I can easily 'see' and feel which screen is PWM in a blind test. I've tried it on occasions with friends and across organizations. It's a nightmare!
I'm really glad I stumbled on this article... I may have to go for a different monitor than I was expecting, I'm really sensitive to PWM I think.
That is exactly the problem I have, diagnol lines get burned into my retina even when I close my eyes they are still there. It doesn't happen every single time, but it happens frequently enough to cause me concern.
Now I need to figure out which monitors don't have PWM. Does this one? amazon.com/MSI-Compatible-Refresh-Optix-MAG274QRX/dp/B09PF7Z1HD/
I think this is the one I will get now if you can figure out a way to confirm if it has PWM or not. Rtings maybe will tell me... I think rtings is a paywall website these days though? last I checked it said I had like 1 review left that I could look at... so eh
The MSI monitor you quoted should NOT use PWM. That are its specs even according to Rtings.
Thing is, IPS can use PWM but it can also go without it. OLED are way more difficult to be found with non-PWM (DC) dimming.
And yes, Rtings went a bit downhill lately but they are a good starting point. You may also want to check blurbusters.com
And yes this is crazy my Eizo doesn't work with Netflix! Probably because its old and uses HDCP 2.2 versus the new 2.3
If you don't care much about contrast, viewing angles and rich colors (all relative ofc), the LCD variants are the answer.
As for the HDCP, some vendors offer firmware updates to 2.3
For TV I use Samsung QLED and LG NanoCell but I prefer the LG ones.
Phones are another thing - all my phones are with OLED and PWM, simply because there isn't any current model with non-PWM dimming. At least not to my knowledge.
