Set it to GPU. For most people, on most monitors, that is the whole answer. GPU scaling gives you more control over how the image is stretched, produces more consistent results across different screens, and offers modes like integer scaling that your monitor cannot do on its own. The cost is a delay so small that you would need lab equipment to measure it.
There is more to the story, though. This setting only does anything in one specific situation, a few competitive players still swear by display scaling, and some monitors handle scaling badly or refuse odd resolutions outright. This guide covers what the setting controls, when it actually matters, how the two options differ in image quality and input lag, and how to change it on both NVIDIA and AMD cards.
What does the scaling setting actually control?
Your monitor has a fixed grid of pixels. A 1080p screen has exactly 1920 pixels across and 1080 down, and that never changes. This fixed grid is called the native resolution.
When your PC sends an image that matches the native resolution, every pixel in the signal maps to one pixel on the screen. Nothing needs to be stretched, and the picture is as sharp as the panel can make it.
The problem starts when the image does not match. Run an old game at 1024×768 on a 1080p monitor, or drop your game resolution to gain frames, and something has to blow that smaller image up to fill the screen. That job is called scaling, and there are only two devices that can do it:
- Your GPU, which resizes the image before it leaves the graphics card. The monitor then receives a normal native-resolution signal and displays it as is.
- Your monitor, which has a small scaler chip inside it. The GPU sends the low-resolution signal untouched, and the chip stretches it to fit the panel.
The “Perform scaling on: GPU or Display” dropdown in the NVIDIA Control Panel, and the GPU Scaling toggle in AMD Software, simply pick which of these two devices does the work. The end result on screen is the same idea either way: a smaller image stretched to fill a bigger grid. What changes is who stretches it, how well, and with how much control.
Key point: scaling only happens when the image is below your monitor’s native resolution. If you run your desktop and games at native resolution, which most people do, this setting sits idle and does nothing at all. Do not expect any change in sharpness or speed at native resolution no matter which option you pick.
How GPU scaling works
With GPU scaling, the graphics card renders the frame at whatever resolution the game asked for, then resamples it up to the monitor’s native resolution before sending it out. As far as the monitor knows, it is receiving a perfectly normal native signal, so its own scaler never wakes up.
This has three practical benefits.
First, the result is consistent. The same card produces the same scaled image on any screen you plug in, so you know what you are getting. You are not gambling on the quality of whatever scaler chip happens to live inside your monitor.
Second, you get options. Because the GPU does the stretching, the driver can offer several scaling modes: keep the original shape with black bars, stretch to fill the whole panel, center the image without any stretching, or duplicate pixels cleanly with integer scaling. Monitor scalers usually offer one behavior, sometimes two, and cheap ones just stretch everything to full screen whether it distorts the image or not.
Third, it works with resolutions your monitor would reject. Some panels show an “out of range” or “input not supported” error when they receive a signal they do not recognize, especially old 4:3 or 5:4 resolutions. With GPU scaling, the monitor never sees those resolutions, so the problem never comes up.
How display scaling works
With display scaling, the GPU sends the low-resolution signal exactly as the game produced it, and the scaler chip inside the monitor stretches it to fill the panel.
How good that looks depends entirely on the chip. Higher-end gaming monitors and modern TVs often carry capable scalers, and a few do a genuinely nice job. Budget monitors usually apply a basic stretch that leaves the image soft and slightly mushy. There is no way to know which kind you have without trying it, because scaler quality almost never appears on a spec sheet.
Control is also limited. Many monitors offer a small aspect ratio menu in their on-screen settings, with choices like “wide” and “4:3”, but plenty offer nothing at all and simply stretch every input to fill the screen. If a 4:3 image getting smeared across a 16:9 panel bothers you, and it should, a monitor with no aspect control gives you no way to stop it.
The one traditional argument for display scaling is speed. A hardware scaler is a dedicated circuit doing one simple job, so it can shave a small slice of time off the pipeline compared with asking the GPU to do the resize. How small? That is the next section.
Does the choice affect FPS or input lag?
For frame rate, no. Resizing a finished frame is trivial work for any modern graphics card. It happens in the display pipeline after the frame is rendered, and the performance cost is so small that benchmarks cannot separate it from run-to-run noise. You will not gain or lose FPS by switching between GPU and display scaling.
For input lag, the honest answer is: barely, and it can go either way. Display scaling is often the faster path on paper because the monitor’s dedicated chip adds almost nothing, while GPU scaling inserts one extra processing step. The measured difference is typically around a millisecond or less. For scale, a single frame at 240 Hz lasts about 4.2 milliseconds, and total click-to-photon latency in a well-tuned competitive setup still lands somewhere between 15 and 30 milliseconds. A sub-millisecond difference disappears inside that.
It can also flip. Some monitor scalers are slow, and a sluggish chip adds more delay processing a non-native signal than the GPU would have. On those screens, GPU scaling is both better looking and faster.
There is one more wrinkle worth knowing. A monitor fed a native-resolution signal can sometimes skip parts of its internal processing entirely. Because GPU scaling always outputs a native signal, it keeps the monitor on that fast, predictable path regardless of what resolution your game runs at. That consistency is part of why frame pacing often feels smoother with GPU scaling even when the raw latency numbers are a wash.
When GPU scaling is the right pick
For most setups, most of the time. These are the situations where it clearly earns its keep.
Old games with square-ish aspect ratios. Titles built for 4:3 or 5:4 look wrong stretched across a widescreen panel. Faces widen, circles become ovals. Set the scaling mode to aspect ratio and the GPU keeps the original proportions, filling the leftover space with black bars. Everything on screen looks the way it was drawn.
Pixel art and retro emulation. Integer scaling duplicates each pixel by a clean whole number, two times, three times, four times, instead of blending neighboring pixels together. The result is razor-sharp instead of smeared. It is a GPU-only feature on both vendors: NVIDIA offers it on GTX 16 series and RTX cards (the Turing generation and newer), and AMD requires GPU Scaling to be switched on before integer scaling becomes available. A 1080p image on a 4K panel is the perfect case, since 3840×2160 is exactly double 1920×1080 in both directions.
Stretched resolutions in competitive shooters. Plenty of Counter-Strike players run 1280×960 or 1024×768 stretched to full screen because wider player models feel easier to track. GPU scaling with the full-screen mode makes this work reliably, and the “override the scaling mode set by games and programs” checkbox in the NVIDIA Control Panel stops individual games from quietly switching the behavior back.
Monitors with weak or missing scalers. If lowering your resolution turns the picture into soup, or the screen goes black with an unsupported-signal message, GPU scaling routes around the monitor’s limitations completely.
Anyone who values predictability. One setting, one consistent result, on every screen you own now or buy later.
When display scaling can make sense
It is not useless. Two situations justify it.
The first is competitive play on a monitor with a known fast scaler. If you are the kind of player who caps background processes and buys a mouse for its click latency, and your specific monitor handles non-native input quickly, display scaling recovers a fraction of a millisecond. Whether that fraction is worth giving up aspect control and integer scaling is a personal call, and for most players it is not.
The second is troubleshooting. On rare setups, GPU scaling misbehaves: a brief black screen when switching resolutions, a conflict with a specific refresh rate, or an interaction with adaptive sync that causes flicker. Switching the work to the display is a quick way to test whether the GPU-side path is the problem.
If neither applies to you, there is no reason to choose it.
How to change the setting on an NVIDIA card
- Right-click an empty spot on the desktop and choose NVIDIA Control Panel. On Windows 11 you may need to click “Show more options” first.
- In the left pane, under Display, click Adjust desktop size and position.
- On the Scaling tab, find the Perform scaling on dropdown and choose GPU or Display.
- Above it, pick a scaling mode: aspect ratio, full-screen, no scaling, or integer scaling.
- If you want your choice enforced everywhere, tick Override the scaling mode set by games and programs.
- Click Apply. The screen may blink once while the change takes effect.
NVIDIA documents each mode and the GPU-versus-display behavior in its Control Panel scaling guide, which is worth a skim if an option is grayed out on your system, since availability depends on the GPU generation and the connection type.
How to change the setting on an AMD card
- Right-click the desktop and open AMD Software: Adrenalin Edition.
- Type “Display” into the search box and open Display Settings.
- Set GPU Scaling to Enabled. The screen going blank for a moment here is normal.
- Choose a Scaling Mode: preserve aspect ratio, full panel, or center.
- To use integer scaling, enable it on the same page once GPU Scaling is on.
AMD’s own GPU scaling support article covers the requirements: the feature works over HDMI, DisplayPort, and DVI, and the display itself should be set to its native resolution and refresh rate in Windows.
One note for AMD users on current versions of Windows: the operating system sometimes handles desktop resolution changes through its own composition layer, keeping the actual output signal at native resolution regardless of the toggle. When that happens, the GPU Scaling switch mostly matters for exclusive full-screen games and for turning on integer scaling, not for the desktop.
The scaling modes, explained
Both vendors offer the same core behaviors under slightly different names.
| Mode (NVIDIA / AMD) | What it does | Best for |
| Aspect ratio / Preserve aspect ratio | Enlarges the image as far as it can without changing its shape, adds black bars where needed | Old 4:3 games, anything where correct proportions matter |
| Full-screen / Full panel | Stretches the image to cover the whole screen, distorting the shape if it must | Stretched-res competitive play, hiding black bars at any cost |
| No scaling / Center | Shows the image at its true size, centered, with a black border all around | Maximum sharpness when a smaller picture is fine |
| Integer scaling | Multiplies each pixel by a whole number for a perfectly crisp enlargement | Pixel art, emulators, 1080p content on a 4K screen |
Aspect ratio is the safest default. Switch to full-screen only when you specifically want the stretch, and to integer scaling when you want retro content to stay sharp.
This is not the same as Windows display scaling
One naming collision trips people up constantly. Windows has its own setting called display scaling, found under Settings, System, Display, with values like 100%, 125%, and 150%. That setting changes the size of text, icons, and windows so they stay readable on high-resolution screens. It is DPI scaling, it lives in the operating system, and it has nothing to do with your GPU driver.
If your goal is bigger or sharper text on a 1440p or 4K monitor, adjust the percentage in Windows Settings and leave the GPU driver alone. If your goal is controlling how lower-resolution games fill the screen, that is the GPU and display scaling covered in this article. The two settings do not interact, and changing one will never fix a problem caused by the other.
Frequently asked questions
Does GPU scaling lower my FPS?
No. Resizing a finished frame is a tiny amount of work for a modern graphics card, and it happens after the frame is rendered. Benchmarks show no measurable frame rate difference between GPU and display scaling, so pick based on image quality and features, not performance.
Does this setting matter if I always play at native resolution?
No. Scaling only activates when the signal is below the panel’s native resolution. At native, every pixel maps one to one, nothing is stretched, and both options behave identically. You can still set it to GPU so the right behavior is ready when you do drop resolution.
Which option is better for CS2 or Valorant?
GPU scaling for almost everyone. It makes stretched resolutions work reliably, and the latency difference against display scaling is around a millisecond or less, a fraction of a single frame at 240 Hz. Only a monitor with a proven fast hardware scaler makes display scaling worth testing.
Why do lower resolutions look blurry no matter which I choose?
Because standard scaling blends pixels together to fill the gaps, and no scaler can invent detail that was never rendered. For clean results, use integer scaling with resolutions that divide evenly into your panel, like 1080p on a 4K screen, or simply stay at native resolution.
Do I need GPU scaling turned on to use a stretched resolution?
Usually, yes. Set scaling to GPU, choose the full-screen (or full panel) mode, and on NVIDIA tick the override checkbox so games cannot switch the mode back. Without GPU scaling, the result depends on your monitor, and many panels either add black bars or reject the resolution.
Conclusion
Choose GPU scaling and pick the aspect ratio mode as your default. The setting only becomes active below native resolution, and when it does, the GPU gives you a consistent image, proper aspect control, and integer scaling, all for a latency cost under a millisecond. Reserve display scaling for a monitor with a proven fast scaler or for troubleshooting. A good result looks like this: native resolution stays untouched, old games keep their shape, and low-resolution content stays sharp instead of smeared.
