Downsampling, a simple method for making your pc-games look better.

Did you use Corky's settings? That's how I was able to.
Some monitors can't make it work at 60hz though, I can get 2160p 60hz easily when I'm using my monitor, but my TV can only achieve 3200x1800 at 60hz.
These are my timings, try fucking around with the Hz first and the Total Pixels second:
I tried this on my GTX 275 but it fails at the first step.
I get the "Test failed. Custom Resolution 2560x1440 at 60 Hz (32-bit) is not supported by your display" (Native res is 1920x1080p)
Not sure if this happens due my GPU or my monitor. Sure the GPU is old, but if it's my monitor, I'm going to get sad that I can't use this method even with a GPU upgrade.
It's connected by DVI and scaling is set to GPU

Been playing around with these setting the last few days and 3200x1800 seems to be my best (without causing my monitor to flick to black on and off). It makes any game look awesome, but the sacrifice of 120hz is too much for me. I'll still use it on any pc game that has a locked frame rate though, like Dark Souls.

I'm using a 4 year old Vizio TV via HDMI for 4K, lol. Works somehow.

Pretty sure it's the gpu and not the monitor though I could be wrong but keep in mind the older the gpu the worse its ability to downsample and that's not referring to the performance aspect rather the very ability to be able to downsample or not.
Are these resolutiobs running at 60 Hz ? Otherwise they might not show up ingame.
Also, make sure to tick the "override resolution settings in games and application" ( or w/e it's called ) setting.
Wow! At first I tried this res and got a black screen but then copied the timing from that screenshot and now my screen just came up OK and nvidia control panel passed the test! Very interesting! Time to test this out with some emulators
Thanks scitek!Cannon Goose

Oh wow, this worked for me as well. Thanks for the settings, scitek!
Guys....3840x2160 works as far as getting it to display, but two problems:
1)It chops off the bottom portion of the windows screen, elimination all of my taskbar, system tray, etc.
2)My PC is connected to a Yamaha Receiver, then to my front projector(which has a native res of 1080p), but when doing 3840x2160 I get no sound at all. Nividia's HDMI out speaker icon is changed to the normal windows icon.
Can you tell me what I can do to resolve this? 3200x1800 is working fine by the way, and does not suffer from either issue.

No body?
1) Check your overscan settings in the nvidia control panel unless you already have, should be options there to battle portions of the screen getting cut off.
2) Not entirely sure, could it be that there simply isn't enough bandwidth for the audio when running 4k@60 Hz?

Yeah it's not out of the ordinary that menus, hud and gui scale badly as they often are usually (?) 2D-elements that look like shit when blown up or sometimes it's the opposite they don't scale at all and are barely legible.

Corky,
I have a BenQ W1070 which is a native 1080p projector that can also do 3D at 144Hz (if that even mattera). Would I be able to down sample using the method you have outlined with this projector? It is connected to the pc via hdmi.

Downsampling relies more on the gpu than the monitor actually, what kind of gpu do you have?

It is ATI I just checked sciteks page instead from the OP. getting down sampling to work really well on a projector is going to be very helpful for some older titles. Using the Dolphin emulator and what I thought to be down sampling for their games is what got me to this thread in the first place.
Thanks for this thread as i will probably upgrade to an nvidia card depending on timing and price. I think I will need 9xxx series card or a GTX 880 to take full advantage of this since I didn't realise until today that the 8xxx series is just a rebadge and my current card is not good enough to do really high level down sampling.

Shouldn't be different from any other Nvidia card.
OK, thanks. This is my first gaming PC so I'm new to this stuff.
I got a 780 yesterday and tried out downsampling with it today. Got Witcher 2 running at 3860 x 2070 30 fps stable. It is really pretty like that I gotta say. That was max settings except ubersampling. Need to figure out how to remove the UI for posting in the bullshot thread next.
Not sure how the 770 will do since it is a different chip.

Just got a pc that can do this, want to clarify something, so when downsampling do I have to run the game in fullscreen or can I do fullscreen borderless window?
I have been downsampling on the GTX 780 just fine, it was exactly identical to setup as any other Nvidia card I have had. I can't get 2160p / 4k in games, though, seems to max at 1800p I'm on a 1080 Toshiba TV and it works fine for my desktop but just black screens when I try to load in a game.
I am sure this is a product of the TVs limits and not the card's, however.

Goddamn it most of this does not work on my Blade simply cause nVidia's mobile GPU drivers don't support it! I can get Inspector to supersample Mass Effect 3 for example though, which is cool as fuck and runs at a nice framerate. But I can't seem to do anything at all to get Mirror's Edge to supersample, the guide outlined in the OP doesn't work at all cause I don't even have any of those options in the control panel... Anything I can do?

For those of you with an Asus VG248QE, here you go.
3840 x 2160 @ 60hz via Dual link dvi
if there is a blinking problem, lower front porch and sync width proportionally until blinking dissapears

I don't have the "GPU" scaling option but only Display, what difference can it make?

Just started trying this downsampling trick on my 780 and so far, I'm able to get games at 2560x1440 running fine but when exiting back to the desktop, I get stutters and freezes for a few seconds. Does this have something to do with the resolution switching back to 1920x1080 or something else? Seems to only happen when running a downsampled game then returning back to desktop.
Yep, hit the nail on the head. It's just switching back to 1080p.

Thanks for the excellent post, OP.
This made me laugh. K2Valor, you have an optimistic soul

I'm guessing there is still no fix for us U2711 users? Linke dmy PC up to my bro's 1080p Ben Q and ran at 4K and shit was glorious.

One thing at that resolution my screen looks as if someone put a bright yellow filter over it .
is this damaging my screen ?

Hold the frigging phone!
Win 8.1 and relevant Nvidia drivers has netted me 4K on my U2711! Limited to 24Hz, though, although i'd probably be running round that area with most games anyway.
This is living.
Edit: Okay, Skyrim and TW2 are refusing to play ball

I wanted to play a game called Darkstar One on my PC but it crashes if you try to run it at my monitor resolution (1680x1050).
The fix is actually to UNDERsample the screen resolution to a single pixel less (1680x1049).
No idea why this is or why it was never fixed in the game, but it works!

Any 16:9 resolutions, honestly. I have a 1600x900 display on my laptop, and I can actually take that sucker to 2560x1440. It's an older laptop so performance begins to tank rapidly. There's no harm in trying a resolution. If it fails, you try a different one
I tend to stick to:
2560x1440
2880x1620
3200x1800
3840x2160
For Dark Souls, you set the internal resolution at the very top. That game will downsample for you, which is kinda nice. You can put in something crazy like 5120x2880 if you so desire.
