Downsampling vs actual monitor resolution ?

I've been playing around with downsampling on my 1080P monitor while I wait for my 2560x1440 monitor to arrive and was wondering, If I downsample to 1440P through the Nvidia control panel how close is that to an actual 1440P panel in terms of performance and image quality ?

*EDIT* I know the term downsampling doesn't make any sense as I am increasing the resolution but that's what every guide on the net calls it.

A 1080p screen doesn't support 2560x1440. :confused:

However, there is super sampling AA which renders at higher resolution and down samples making edges appear smoother.

Look in the Nvidia control panel, There's an option for custom resolutions, One being the ability to support higher resolutions than the panel supports.
Not sure how it works though.
 
You lower the refresh rate which then lets you use a higher resolution.

eg on a 120hz monitor you can - with a bit of jiggery pokery - put your refresh down to 60hz and then use 2560x1440 so you can do this resolution on a 1080p monitor providing it is a 120hz/144hz one.

Its a bit suck it and see but plenty of people have done it,

You can also lower it further to 30hz and run at UHD '4k' resolution too if your monitor can handle it.
 
Hi

just tried it on my Benq XL2411Z 1080p 1920x1080 144mhz monitor


2560 x 1440 @ 60hz
2560 x 1440 screenshot

3840 x 2160 @ 30hz
3840 x 2160 screenshot

Furmark was the only thing I could find at the mo that showed the screen res. I didnt run the whole test.

Ran Watchdog to first video then quit out then ran Far Cry 2 benchmark and it was okay. Need to test it more really.

Funny thing was if I set it to 3840 x 2160 60hz after about 10 seconds on the desktop the screen went black but if I left it at 3840 x 2160 30hz and then ran Watchdogs/Far Cry 2 at 3840 x 2160 60hz it ran okay.

"4k" gaming on a 1080p monitor eh ! :p

With nvidia it's easy to create custom resolutions, with amd you need to use third party progs I believe.

What you can achieve very much depends on your monitor though. On my Dell 29 superwide (2560 x 1080 native) I can run it at 3440 x 1440 at 60hz with ease.
It's good to do as it gives me a good idea of the screen real estate this res provides, but it looks like utter arse. Text and icons are fudgy and tiny, and it's just not really useable.

Still patiently waiting for a 3440 x 1440 34 inch IPS screen with Gsync that overclocks to 75hz...
 
Just been watching the 4k videos in 3840 x 2160 res on You Tube - Transformers 4 looks wicked. Well the picture quality does not the movie !

Also played a game of World of Tanks in 2560 x 1440 and it does make a difference as to how much you can see.

Think I will still stick to 1080p doesnt seem right pushing the monitor more than it is supposed to be at least I know it works.
 
My BenQ 27" 1080p, using CRU, will do 2720X1530 and I have successfully played Fallout NV and Dishonored, thought it looked great and played well on my R290. No idea how it works though. :D
 
Its the DIY way of doing SSAA which Nvidia removed from the NVCP as its one of the oldest but best and the most FPS hitting AA.

Games do have it like Sniper Elite III and Nvidia support it but you cannot force it in other games using the NVCP like before (can still use NVInspector) but the FPS hit up full is not worth it IMO, I dropped it from 4.0x to 2.4x in above mentioned game.

I loved the downsampling and always felt it looked better....Till I got a higher res monitor. The good thing about downsampling is seeing what frames you will get if you go for a bigger res monitor. At the end of the day, if you have a 1080P monitor and run at 1440P, you are still only going to see 2073600 pixels and nothing will change that.
 
I will make do with CRU until the higher res monitors in the uk drop to reasonable prices, if that ever happens, fed up getting shafted and the prices of this latest bunch don't fill me with confidence. Could always buy a big tv. Was hoping the LG 29UM65-P would drop a fair bit as they don't seem to be shifting, but then the backlight bleed is a bit of a lottery and I don't really want the hassle of dsr or rma. :(:)
 
I played with this last night was able to get my benq xl2411t to run 60 hz at 3840 X 2160 playing diablo 3 i did seem to make things look crisper but the tiny mouse icon caused me to soon move back to 1080

This program adds monitor resolutions, so you can't add higher resolutions unless the monitor can handle them.

so how do you downsample on amds , what program?

I used CRU, I added 2560X1440 and 2720X1530, I can select it from my resolution list, it looks utter rubbish in windows desktop but looks great in games that support it. Currently I am playing Fallout NV @ 1530p and also Dishonored. As I say, I don't know how it works but it does. The above games play very well at 1530p on my R9 290. :)
