Sorry for the long title, but on an Nvidia card, what is the best way to set up a non-native custom res and ensure the scaling is as good as possible? For example, if one was to make a 3200x1800 custom res and connect the GPU to a 4K display, what is the best process and settings for maximum quality? Are there any issues with framepacing, etc?

Thanks in advance.

Edit - Completely missed the OP question

 

[Garrett Hawke]

Do you want minimum 60fps?

GTX 1080 is the option for sub-4k holding 60fps.

Not the ideal GPU, I just meant the ideal settings in NVCP or something.

30fps is fine.

You can just make a custom resolution easily in the NVCP using the customise button in the resolution section. You should just be able to type in the resolution you want and save it without messing with the timings.

There's also Custom Resolution Utility which lets you do the same thing without having to open up the crusty old NVCP.

Lastly, you could try using Durante's GeDoSaTo which allows for custom resolutions in a number of DX9 games. The nice thing about this is that it lets you choose different scaling options so if you're after quality this would be your best bet, I think.

There's this app Digital Foundry has been using for their 4K on a Budget series of videos, called Custom Resolution Utility by ToastyX. They set up custom resolutions with it, for example 3200x1800. Perhaps something like that is what you're looking for?

Use CRU. It's mindlessly easy and works flawlessly. Been using it for a couple months now no issue.

Another one for Custom Resolution Utility. Digital Foundry even show how to set it up in one of their 4K on a budget videos, I think.

I got my 1080 Ti hooked up to my 4K TV, and sometimes those extra 2.5 million pixels aren't necessary.

^ That's the one!

In the NVIDIA Control Panel you'll want scaling performed on the GPU, like this:

You can either use DSR or setup a Custom Resolution, you enable DSR in "Manage 3D settings by ticking the boxes of the resolutions you desire and adjusting the smoothness, I like my smoothness set to around 23%

In the change resolution menu you can click "customize" and "create custom resolution" to make the resolution option you want.

I've had trouble setting a resolution of 4K this way, I'm not quite sure why as I have no trouble with a resolution of 4K with DSR. I presume it must be due to the timings or something.

Have you acually done this?

This didn't work for me. It worked for downsampling on my 1080p set, but did not work on my new 4K set. Also DSR doesn't enable resolutions below native (which is his problem).

E: I'm gonna go out on a limb and infer that this is what you do on 1080p and you're assuming this will work for him on his 4K set....

Hmm, so it doesn't work for you when trying to downsample from a higher resolution at 4K? I haven't actually tested this on a 4K display however I have had trouble setting a custom resolution of 4K and above with this method.

I presume setting a custom lower resolution such as 3200x1800 should be possible however I haven't actually tried it.

Thanks all

Well, a couple things. You aren't downsampling, you're upsampling at that point. I know dsr doesn't add any resolutions below native.

A custom resolution may be possible, but I had some issues on my LG C7. CRU worked no issue tho.

Maybe it was just my drivers or something.

2560x1080 ultra wide
3440x1440 ultra wide

16.9
2304x1296
2560x1440
2880x1620
3200x1800


Just use the Nvidia control panel to set the custom resolutions up and make sure gpu scaling and keep aspect ratio is enabled. Its easy.

The ultra wide ratios are great for games that allow it and makes for a very cinematic representation, works awesome with oled in the dark as the black bars just melt away.

I really notice the blurring when upscaling a non-native resolution onto my 4k display. Have tried variants between 3200-3600... definitely not sharp enough for me.

What I have found to be ideal is run the display at native res, albeit at an unorthodox aspect ratio. For computer use on a 4k 65" inch display, I've found 192 : 95 to be the ideal ratio. This amounts to a 3840 x 1900 resolution using the CRU in Nvidia. It's 13% less the number of pixels of 4k, and makes windows scaling soooooo much better. I can actually use my TV as a monitor. The benefits in games of a wider aspect ratio is is immense compared to 16:9, and you get a 13-15% performance boost. Unlike 21:9, 192:95 actually has height to it and does not feel too narrow!

The only downside is that this will create black bars, but compared to what 21:9 would be on a 4k display (3840 x 1600), the added 300px @ 3840 x 1900 is a night a day difference.

The Windows desktop will always look a little blurry as the one dot pixel font used will be spread over a few pixels but I find it's great in game.

2880x1620 always seem to look pretty sharp on a 4k screen.
