How to compare graphics results after changing display scale
Compare Graphics Test scores before and after changing display scale, keep conditions consistent, and separate a real GPU change from normal variation.
You changed display scale and now want to know whether your graphics performance changed too. A score can move slightly between runs, so one result before and one after may not tell the whole story.
Use the Graphics Test to compare its shading and fill rate results under controlled conditions. The test runs in your browser and reports a score out of 100. The goal is to change display scale while keeping the other factors that affect a browser test as similar as possible.
Compare the graphics results
- Open the Graphics Test on the display you plan to use. Note the display scale, resolution, browser, and whether the computer is plugged in.
- Close games, video streams, and other demanding apps. Keep the computer on the same power setting, then run the test and note the score, shading power, and fill rate.
- Change only the display scale. On Windows 11, open Settings › System › Display › Scale. On a Mac, open System Settings › Displays and choose a different scaled option, such as Larger Text or More Space, if available.
- Return to the same browser and display, then run the Graphics Test again. Record the new results and check that the display resolution, browser, and power setting have not changed.
- Repeat each measurement two or three times at both scale settings. Compare the typical scores, not just the highest result from one group.
Changing the scale may make menus and text larger or smaller without changing the physical pixels on the display. Keep the display resolution fixed if your operating system allows it. On some Mac displays, choosing a different scaled option also changes the logical desktop size, so note which option you used.
What the result means
The scores are close at both scale settings
A small difference is usually normal run-to-run variation, not evidence that the graphics hardware became faster or slower. The Graphics Test measures shading power and fill rate at 1080p, so a desktop scale percentage is not itself a GPU performance setting. If repeated results overlap or vary by a few points, treat the performance as broadly similar.
The score changes once, but later runs do not repeat it
A one-off high or low score can happen if the browser was busy, the computer was warming up, or another app briefly used the graphics processor. Run the test again under the same conditions. A single score out of 100 is not enough to show a lasting change.
Scores stay lower after the scale change
If several runs at the new setting are consistently lower, something about the test environment may have changed along with the scale. Check whether the display resolution changed, the browser is using a different window or monitor, or the computer is running on battery. A browser graphics score also cannot tell you how much video memory your graphics processor has. For that distinction, see what a browser graphics score cannot tell you about VRAM.
The score improves at the new setting
Repeat the comparison before concluding that the scale caused the improvement. A browser test can be affected by background activity, temperature, and graphics acceleration. If the improvement appears repeatedly, report it as a result observed in that browser and setup, rather than a general increase in the graphics processor's capability.
How to make a fair comparison
- Keep the resolution fixed. On Windows 11, check Settings › System › Display and make sure Display resolution has not changed. On macOS, note the selected option in System Settings › Displays. Do not compare a scale change and a resolution change as if they were the same adjustment.
- Use the same display and browser. If you have more than one monitor, run both sets of tests on the same one. Keep the browser window in the same state, and use the same browser version where possible.
- Wait for the computer to settle. Let updates, file copies, and other heavy work finish before testing. If a laptop is warm after a game or video export, give it time to cool before either set of runs.
- Keep power conditions consistent. Use the same power source and power mode for both comparisons. A laptop may limit performance on battery or when it is set to save power.
- Compare repeated results. Write down each score and the shading and fill rate values. If the difference is smaller than the spread between repeated runs, the test does not show a reliable performance change.
Why display scale can affect a browser test
Display scale changes how the operating system lays out text and interface elements. Browsers also use display information when sizing pages and drawing content. The Graphics Test uses a 1080p workload, but browser behavior, graphics drivers, and the display setup can still influence a browser-based result.
That is why a controlled comparison matters more than trying to predict whether a particular scale should raise or lower the score. If results change only in one browser, repeat the test in the same browser first and check that its graphics acceleration settings have not changed.
