If you’ve opened Nvidia Control Panel and stumbled onto the “Perform scaling on” setting, you’ve probably noticed it does something but couldn’t say exactly what. It controls where image scaling happens when your game or video runs at a resolution that doesn’t match your monitor’s native resolution. The choice is GPU, Display, or a mix of both, and it has real consequences for input lag, image sharpness, and whether black bars show up around your picture.
This matters more than people expect. If you run an older game at 1080p on a 1440p or 4K monitor, or you’re using DSR/DLDSR for extra sharpness, or you’ve got a console-style setup with a TV, this setting decides how that image gets stretched to fill your screen.
What the setting actually does
When the resolution you’re rendering at doesn’t match your display’s native resolution, something has to scale the image up (or letterbox it). There are two places that scaling can happen: the GPU itself, or the display’s internal scaler chip. Nvidia Control Panel lets you force this choice instead of leaving it to whatever the monitor defaults to.
- GPU scaling: The graphics card stretches the image before sending it to the monitor. This adds a small amount of processing on the GPU side but is generally fast and consistent across different monitors.
- Display scaling: The monitor’s own scaler handles it. Quality and speed depend entirely on how good that scaler chip is, which varies wildly between monitors.
- No scaling: The image is shown at its native pixel size with black bars filling the rest, or it gets centered without stretching.
There’s also an “aspect ratio” option that keeps proportions correct instead of stretching a 4:3 image to fill a 16:9 screen, which matters if you play older titles.
Why you’d actually touch this setting
Three situations come up repeatedly:
Old games on modern monitors. A lot of games from the 2000s and early 2010s only support 4:3 or lower resolutions than your current monitor runs natively. Without proper scaling, you’ll either get a tiny image surrounded by black, or a stretched, distorted picture. GPU scaling with aspect ratio preserved usually gives the cleanest result here.
DSR and DLDSR. Nvidia’s dynamic super resolution renders at a higher resolution than your monitor supports, then downsamples for extra sharpness. This process relies on GPU-side scaling to work at all, so if you’re using DSR, you’re already using GPU scaling whether you set it manually or not.
Latency-sensitive competitive play. This is the one that actually matters for buying decisions. Display scalers add processing time, sometimes a full frame or more, before the image reaches the panel. If you’re playing competitively and running a non-native resolution for performance reasons, GPU scaling is almost always the lower-latency choice because it skips the monitor’s scaler chip entirely.
| Scaling Mode | Added Latency | Image Quality | Best For |
|---|---|---|---|
| GPU Scaling | Very low | Consistent, sharp with proper filtering | Competitive gaming, older titles, DSR/DLDSR |
| Display Scaling | Varies, often higher | Depends on monitor’s scaler quality | Casual play, monitors with strong built-in scalers |
| No Scaling | None | Native pixels, black bars | Retro accuracy, pixel-art purists |
Monitor scaler quality is the wildcard here. A high-end gaming monitor often has a scaler that’s barely noticeable in both speed and quality. A cheap budget panel might have a scaler that blurs the image and adds a frame or two of lag. If you don’t know how good your display’s scaler is, defaulting to GPU scaling removes the guesswork.
How to actually set it
Open Nvidia Control Panel, go to “Display” then “Adjust desktop size and position.” You’ll see radio buttons for the scaling mode and a dropdown for how to perform the scaling (GPU vs Display). There’s also a checkbox for “override the scaling mode set by games and programs,” which you’ll want checked if you’re trying to force a specific behavior rather than let individual games decide.
One practical note: some games ignore this setting entirely and handle their own internal scaling through in-game resolution and upscaling options like DLSS. In those cases, the Control Panel setting only kicks in for the desktop compositor or for games that don’t manage scaling themselves.
Does this affect what hardware you should buy
Scaling settings are software, not hardware, but they do interact with your hardware choices. If you’re shopping for a new monitor and plan to run older games or lower resolutions often, check reviews for scaler lag specifically, not just response time. Monitors marketed for competitive gaming tend to have better scalers because manufacturers know this audience cares about input lag. If you’re monitor shopping, browsing gaming monitors with published input lag numbers at non-native resolutions will save you guesswork later.
On the GPU side, scaling itself is a trivial workload, even a mid-range card handles it without breaking a sweat. You don’t need to buy a more powerful GPU just to get better scaling. If you’re due for an upgrade anyway, any current Nvidia RTX graphics card will handle GPU-side scaling identically well, from the lowest tier to the flagship. Where it does matter is DSR and DLDSR specifically, since those techniques render at higher internal resolutions, which does cost real GPU horsepower. If you want to use DLDSR regularly at 4K, you’ll want enough headroom that the extra rendering load doesn’t tank your frame rate.
If you’re building around older or budget monitors without great scalers, it’s worth checking whether a 1440p gaming monitor with a modern scaler chip is a better long-term investment than relying on GPU scaling to compensate for a weak display indefinitely. A good monitor fixes the problem at the source; GPU scaling is more of a workaround.
FAQ
Should I just leave this setting on default?
For most people, yes. The default usually lets the display handle scaling, which is fine on decent modern monitors. Only switch to GPU scaling if you’re noticing lag, stretching artifacts, or you’re specifically using DSR/DLDSR.
Does GPU scaling lower my frame rate?
No, not meaningfully. The scaling operation itself is cheap. Any frame rate impact you see from DSR or DLDSR comes from rendering at a higher internal resolution, not from the scaling step itself.
Why do my old games look stretched and blurry?
Likely because the display or GPU is stretching a 4:3 image to fill a 16:9 screen without preserving aspect ratio. Switch to “aspect ratio” scaling in Nvidia Control Panel instead of “full-screen.”
Does this setting matter for AMD or Intel GPUs?
The concept is the same, but the setting lives in a different place. AMD has an equivalent in its Adrenalin software called “GPU Scaling,” and Intel Arc has similar options in its Arc Control app.
