How to DSR non-native resolution(s)? [SOLVED]
As the thread title implies - I'd like to know how or if it's possible to DSR non-native resolutions. I would like to do this as although my display (21:9 Philips Cinema TV) is natively 1920x1080p, to run in 21:9 I have to run at 1920x823, which when blown up on a big screen causes many jaggies. If I could run 3840x1646 then it'd look loads better, but DSR only wants to do 3840x2160 resolution and ratio (for x4 DSR). I've tried a display EDID over-ride before, and it worked to the extent where NVCP stated my 21:9 custom resolution was the native one, but even so, DSR didn't scale to that res and still based itself around full 1080p. This really could do with a resolution by now (if there is one) as a quick google search put me onto this forum with a thread asking the same question from well over a year ago. Thanks in advance for any feedback or response.

No-one? I've stumbled upon SGSSAA and it makes Dark Souls 2 look epic, but looking for working compatibility bits for other games has immediately become a right pain. So my original issue remains - DSR only applying to native resolution. This seems fixable with the correct know-how, so could someone lend me a hand please? Thanks.

Thank you so very much Guzz for your detailed and helpful input. You've gone to a great effort to assist me, which is greatly appreciated. However, things are not working smoothly right now - I've followed all of your steps and they have all worked as 3840x1646 has become a selectable DSR x4 resolution, but I can't actually use it due to the following two problems... 1) The 1920x823 resolution is present and selectable, but when I try to use it my effective display, Pioneer VSX LX-50 A/V receiver detects an HDMI source (shown via a light on its front panel) but my Philips TV doesn't recognise it as a valid input. 2) I've now completely lost my nVidia HDMI Audio Out option on sound devices, which is what I use to send PCM 5.1 to my Pioneer. So I'm in opposite land right now - have the desired DSR option but no usable video and audio output! Lol. I'm furiously trying to restore lost functionality, but so far nothing has workked, even after removing the custom resolution and doing a clean driver reinstall.

EDIT: As I was typing this, you've replied with more info - so thank you kindly again for this! My original response is as follows... Ok, all is fixed now... 1) The audio issue was simply due to driver uninstallation process being messed with by a third party uninstaller that I normall use - IObit Uninstaller. Doing a removal in safe mode with DDU allowed 353.06 to fully install and operate as normal, inc. sound. 2) I couldn't get a working resolution via CRU, so I used nVidias "Resize Desktop" mode to allow 1920x820 within a full 1080p output, restoring display functionality. I then just altered the hex code to 34 03 (820 in decimal) and it works!!! The image quality has lost a little of the blurriness obtained when I tried SGSSAA, presumably due to a differing sampling method, but I'm still very happy with the results...

I'm no longer tempted by 4K TVs for now!! I hope that the removal of the required hex code is temporary and returns asap so fixes to newer drivers are possible. All the best!

Okay, thanks! I'll try that out. Hope it works. Edit: Yes. Yessssssssss! Flawless! Finally, high end 4K across all backends! Does this tool work with every driver or just below a certain one like above? And why the hell does nvidia nerf everything that has no problem? They do this in EVERYTHING they do. WHY?

Okay so I think I noticed something. When I do what I wanted above, seems like 1 of 2 things happen in games: 1. AnisoAA gets disabled because of normally unsupported resolution 2. The pixels of the bounding screen get squished together causing re-jaggying Any insight on this? Seems like the ground shimmers alot in games when I use 4096x2304 as the desktop resolution on 1080p native rez screen (and set the same in-game) as if there is no smoothing or anything going on.

@ Shinra: Why don't you try running at 3840x2160 instead? In theory it should scale much better with 1920x1080 as that'll be x4 DSR whereas you're trying x4.511 DSR - a rather odd number that'll probably degrade the image quality compared to x4. I'm also not sure I understand what you're describing with the "no smoothing" comment, but you are selecting the higher resolution within your games right? I leave my desktop at x1 resolution and only use x4 within games. @ Guzz / Anyone: I've noticed that the registry adjustment / hack is overwritten with standard values every single time the pc boots up, or I re-enable the display (I run 2 completely different setups from one pc, so disable the unused display when not required). I've already exported the key set with the modified values so when I lose my desired key settings I can import the modified key from my desktop then use CRU to restart the driver, therefore it's quickly fixed - but I'm wondering how / if I can stop the registry key from being automatically changed without my consent. I altered the permissions values by removing inheritable control from parental sources, but this didn't work. I can get by as is, but still wonder if this can be stopped therefore improved.

I'm a little leery of downgrading to such old drivers. I have a GTX 1070 on win10...this driver pre-dates pascal, doesn't it? Will it cause problems for my system?

@Large Style: Because 4096x2304 is the resolution the completely gets rid of jaggies in everything. While 3840x2160 still leaves a bit of jaggies behind. Was there any fix to get this working in the new drivers yet? Exit, nevermind, I see a new version that works with the newer drivers on page 67.
