Resolution locked with DisplayPort at 1080p VS HDMI 2160p

[NRG-R9T]

Anybody sharing the same problem? Does AC7 over DisplayPort only support 1080p screen resolution?

I initially played AC7 over Steam at an HDMI connected TV (HDMI 2.0 compatible and HDMI 2.1 cable) and PC Monitor (HDMI2.0, DisplayPort 1.2) both at 2160p resolution. No problem and works great.
Then I connected the monitor by a DisplayPort 1.4 cable and the Resolution never goes above 1080p no matter what I tried, except I haven't the gamesettings.ini file tweaks.

I have to add that I play AC7 on a GNU-Linux system by Steam Play (Proton), but by what I read, AC7 is just a console port with the least acceptable effort possible and I know there is no DisplayPort in the console world. I still enjoy the game greatly. :)

you do know that Ultrawide Monitors are quite exotic, right? lol

The forum is a mistake.

Right, what resolution exactly are you trying to play at? Have you tried putting the game into windowed and then back into fullscreen? I seem to remember that fixing it for most people who had issues with it maxing at 1080p.

@JtDarth: 2160p is the preferred resolution, as it runs well. I tried the windowed/fullscreen trick before I asked here. DP seems to be locked to 1080p. I still could run it 2160p by switching back to HDMI. No problem. just strange.

Right. Can you do 4k@60 in other games, or is it just AC7 not doing it with display port? Have you tried using your older Display port '1.2' cable again, rather than the newer '1.4'? Or even just a different display port cable in general?

From wikipedia:
DisplayPort cables differ in their transmission speed support. DisplayPort specifies four different transmission modes (RBR, HBR, HBR2, and HBR3) which support progressively higher bandwidths. Not all DisplayPort cables are capable of all four transmission modes. VESA offers certifications for each level of bandwidth. These certifications are optional, and not all DisplayPort cables are certified by VESA.

Cables with limited transmission speed are still compatible with all DisplayPort devices, but may place limits on the maximum resolution or refresh rate available.

DisplayPort cables are not classified by "version". Although cables are commonly labeled with version numbers, with HBR2 cables advertised as "DisplayPort 1.2 cables" for example, this notation is not permitted by VESA.[40] The use of version numbers with cables can seem to imply that a DisplayPort 1.4 display requires a "DisplayPort 1.4 cable", or that features introduced in DP 1.4 such as HDR or DSC will not function with older "DP 1.2 cables", when in reality neither of these are true. DisplayPort cables are classified only by their bandwidth certification level (RBR, HBR, HBR2, HBR3), if they have been certified at all.


This seems to indicate that you may actually have a cheap pos cable that's not functioning correctly/high enough bandwidth, hence why I mention trying again with your older cable/getting a new cable. If it's not letting your resolution go above 1080p, it may be the case that the cable doesn't support the bandwidth needed for 4k, or even that it doesn't support higher than 4k@30hz, which I could see also being the problem.

Of course, I'm not stupid. :D It's just AC7, that's why it's strange. Everything else runs in 4K/60hz mode on my monitor. My DP-Cable transfers 25,92Gbps via HDBR3. (https://www.purelink.de/de/anschlusskabel/displayport/displayport-kabel/3049/displayport-1.4-kabel-pureinstall-3-00m?c=2132)

Widescreen and high resolution, was never intended for PC Gaming? REALLY?? Is that why my widescreen has displayport, low latency, High frame rate, multiple high speed usb's and multiple HDMI's, reticle on display, and HDR? Is it to keep up with Technology or to push the Industry to keep up with my privilege? Software and GPU Hardware, is actually way ahead of our NEW PIECES of TECH. Graphic Card Technology actually holds themselves back, due to TV and Monitor companies wanting to make money selling and dulling technology out. The gaming software, can easily follow suite with the GPU Technology. I have really low latency 1080P gaming monitors, and they don't compare to the latest greatest widescreens. Make sure to clean the bugs out of your cave and wash off your privilege to make offensive comments, every once in a while.

Whole post is full of inaccurate ♥♥♥♥♥♥♥♥.
No, graphics cards technology is not holding itself back. Only the higher end of existing hardware really handles UW (not 'widescreen' as you ignorantly claim) in new games without having to drastically drop settings and seek a max of 60 frames.

And yes, the cost barrier to entry means your hardware is niche hardware that isn't being looked at for standard any time soon. In other words, yes, check your monetary privilege. Literally less than 5% of steam users have an ultrawide monitor at the moment. IIRC, the actual number is closer to 3%.

And no, UW monitors were not originally intended for gaming. They started out intended for use by professionals for productivity purposes, with the larger amount of screen real estate easing multitasking without needing to setup a multimonitor system. That hasn't changed. What changed is that they discovered that by adding 'gamer' features and marketing it as a step up for gaming, they finally started selling the ♥♥♥♥♥♥♥ things in sufficient numbers to break even.
The 'multiple high-speed usbs' and 'multiple HDMI'? That is intended to allow it to be used as a general purpose display. IE, to use it as a replacement for a TV, the same way many people already do with their 16:9 monitors. To say nothing of those features only being present on higher end and more expensive versions of the monitors.
The fact that such a display resolution requires extra work to support on the developer's end and provides an advantage in the form of greater FOV, indicates that it's still early in it's lifecycle and nowhere near standard.
16:9 Only became standard because Hollywood pushed for it, and it was, as a result, the aspect ratio chosen when movies and tv switched from VHS to DVD. Even then, it took nearly a decade after the initial standard change for it to actually fully replace 4:3.

Once again, Ultrawides are not the standard, and will not be the standard for quite a long time, unless there is something that goes down to push it as an industry standard. I don't see that happening yet, given that the TV and Movie industry are currently more interested (and rightfully so) in increasing resolution rather than ♥♥♥♥♥♥♥ about with aspect ratio.
Check your privilege, and avoid making ignorant comments.

As an early adopter of a tech item, you should already know to not expect total support, let alone flawless support. They are too expensive and require too powerful a GPU for the majority of users to afford.

Thanks for the knowledgeable input.

[NRG-R9T]

Actually 16:9 finally became standard at users home when HD LCD TV screens became more affordable, 16:9 format gave a better yield for the display machines to cut out and even then most Notebooks and PC Monitors still had a widescreen ratio of 16:10. 16:9 took over PCs, when it was TV standard and production lines ran TV and PC displays together.

I guess it is not the right time to say I have the same issue with 16:9 screen plugged through DisplayPort?
