What’s actually slowing this PC down?

Usually, no: leave HDR set to On When Supported (or the equivalent automatic mode) so SDR games stay in their native format. On PS5, Always On converts every non-HDR game and app to HDR, which can look better or worse depending on your television’s tone mapping and calibration. Xbox Series X|S can apply Auto HDR selectively to supported older games, so HDR capability is worth leaving available there—but it is not a guarantee that every SDR title will improve.
The practical answer
HDR is not a universal picture-quality upgrade. It is a different brightness and color pipeline. An SDR game contains an SDR image; forcing that image through HDR conversion changes how the console and display interpret luminance, highlights, shadows and color. The result depends on the game, the console’s conversion behavior and the TV or monitor.

Use this baseline:
- PS5: choose On When Supported. Non-HDR games remain SDR. Test Always On only for a specific game if you prefer its converted image.
- Xbox Series X|S: leave HDR10 capability enabled if you want Auto HDR to enhance supported backward-compatible SDR games, but evaluate each title independently.
- Any console: if SDR becomes dramatically lighter or darker, loses shadow detail, develops gray blacks or black bars, return to native SDR and correct the display settings.
There is no published statistic proving that one setting is best for every console game and every screen. The reliable recommendation is conditional: preserve native SDR by default, then make a controlled comparison when a console offers an enhancement such as Xbox Auto HDR.
What changes when SDR is sent as HDR?
Standard dynamic range and high dynamic range use different assumptions about peak brightness, reference white and available luminance. When an SDR signal is displayed natively, the game’s original mapping determines its mid-tones, black level and highlights. A forced HDR mode must reinterpret those values for an HDR output space.

That reinterpretation can produce a pleasingly brighter image, but it can also make the picture look washed out, overly dark or unnaturally saturated. A display then performs its own tone mapping: it compresses HDR luminance and color into the range the panel can actually show. Two televisions receiving the same converted signal can therefore produce visibly different results.
Microsoft’s Advanced Color documentation defines SDR reference white as the brightness at which diffuse white appears inside an HDR scene. The documentation notes that desktop HDR monitors are commonly set around 200 nits (Microsoft, 2022). That reference point, the panel’s peak brightness and its tone-mapping curve all affect how an SDR game appears after conversion.
PS5: On When Supported versus Always On
PS5 exposes the clearest choice between preserving SDR and forcing conversion. Sony describes the modes this way:

- On When Supported: “If you select On When Supported, games and apps that aren’t HDR-compatible display in SDR (standard dynamic range).”
Those statements describe behavior, not a quality ranking. Always On does not add HDR artwork or HDR lighting data that the game never authored; it transforms the existing SDR output. Whether that transformation is attractive is a display-and-game question.

Why On When Supported is the safer default
Native SDR keeps the game’s authored brightness relationships intact and avoids an extra conversion step. It is the appropriate starting point for games that were not designed for HDR, especially when you want consistent black levels and neutral mid-tones across a large library.
When Always On is worth testing
Some players prefer the visual character of the converted image: brighter menus, stronger apparent contrast or more vivid colors. Test it only after recording how the same scene looks in On When Supported. Keep the setting if the converted picture preserves highlight detail, maintains genuinely black shadows and does not make skin tones or neutral surfaces look exaggerated.
PS5 comparison table
| PS5 setting | Non-HDR game output | Potential benefit | Potential problem | Best use |
|---|---|---|---|---|
| On When Supported | SDR | Preserves the game’s native SDR mapping | Does not apply HDR conversion to SDR titles | Default for accuracy and predictable behavior |
| Always On | Converted to HDR | May look brighter or more contrasty on a well-calibrated display | Can clip highlights, raise or gray blacks, crush shadows or look excessively bright | Only when a particular game looks preferable after direct comparison |
| HDR disabled | SDR | Removes HDR output from the chain entirely | HDR-authored games will not use their HDR presentation | Troubleshooting a defective or badly calibrated HDR setup |
Xbox Series X|S: Auto HDR is selective
Xbox describes Auto HDR as follows: “Auto HDR automatically enhances SDR games that pre-date HDR technology, enabling them to deliver brighter, more colourful worlds.” The important word is automatically in the supported-title sense, not “every SDR game.” The feature is applied selectively to compatible backward-compatible games; unsupported titles remain SDR.
For that reason, leaving HDR10 capability available on an Xbox Series X|S can be useful even when you play older SDR software. It gives the console permission to use Auto HDR where Microsoft has enabled it. It does not mean that every title receives the same treatment, nor that every display will show the enhancement naturally.

How to judge an Auto HDR title
Use a repeatable scene rather than a title screen. Compare a dark interior, a bright sky or lamp, colored foliage and a neutral gray or white surface. Look for preserved detail at both ends of the range. If the sky becomes a flat white patch, dark rooms lose texture or the entire image appears hazy, the conversion is not helping on your screen.
Do not infer quality from saturation alone. Stronger color can be the result of clipping or an aggressive display preset rather than additional image information.
Six criteria for deciding which mode looks right
Evaluate the same game, scene and TV input while changing only the console output mode. Score each criterion separately:
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →- Native SDR accuracy: Does the image resemble the game’s intended brightness and contrast without a gray veil or crushed blacks?
- Highlight detail: Can you still distinguish clouds, lamps, snow and bright reflections, or do they merge into white?
- Shadow detail and black level: Do dark surfaces retain texture while blacks remain black?
- Mid-tone brightness: Are faces, roads and walls comfortably visible without looking flat or overexposed?
- Color neutrality: Are skin tones, grays and whites natural, or has conversion made them tinted or unnaturally saturated?
- Compatibility and convenience: Does the mode behave correctly across your library, and does it require repeated calibration changes?
A mode that wins only on vividness but loses highlight and shadow detail is not an upgrade. A slightly less dramatic image with intact detail is usually the more faithful choice.

A controlled PS5 or Xbox test
Make the comparison before changing several picture controls at once. If the display supports separate SDR and HDR presets, note both sets of values so you can return to them.
- Start with the console’s automatic or native behavior: PS5 On When Supported; Xbox with HDR capability enabled.
- Choose a game and a scene containing a bright highlight, a dark area and neutral-colored objects. Pause in the same location if the game allows it.
- Disable aggressive dynamic contrast, vivid color enhancement and similar automatic processing temporarily. These features can hide what the console conversion is doing.
- On PS5, switch to Always On and return to the identical scene. On Xbox, compare the Auto HDR presentation with the game’s ordinary SDR presentation when the title and system provide both options.
- Check highlight clipping, black level, shadow texture, mid-tone brightness and neutral colors using the six criteria above.
- Re-run the console’s HDR calibration after changing the television’s picture mode. Calibration values made for one preset should not be copied blindly into another.
- Keep the mode that preserves detail and looks consistent across several real gameplay scenes, not merely the one that appears brightest in a menu.
Why the same setting looks different on two displays
HDR output is constrained by the panel. A television with higher peak brightness may preserve highlights that another set compresses. A monitor configured near the 200-nit SDR reference-white example in Microsoft’s documentation can make an SDR-to-HDR conversion appear very different from a living-room television using a brighter or more aggressive tone map.
Input-specific picture presets add another variable. Many displays store separate brightness, gamma and color settings for SDR and HDR. Switching the console mode can therefore switch the entire preset, making the image seem dramatically lighter or darker even before tone mapping is considered.
For a neutral comparison, use a standard or game picture mode, turn off dynamic contrast and vivid processing, and let the display switch between its SDR and HDR presets. Once you select a mode, you can re-enable processing deliberately if you prefer its appearance, but document the change so troubleshooting remains possible.

Troubleshooting bad SDR results
SDR is much lighter or darker after enabling HDR
Microsoft’s XR-131 guidance treats “The SDR image is significantly lighter or darker than the HDR image” as a failure example. First revert to native SDR or PS5 On When Supported. Then check the television’s input-specific SDR brightness, gamma and black-level settings, followed by the console’s HDR calibration.
Black bars, a smaller image or an incorrect aspect
XR-131 also identifies a smaller image and black bars as failure conditions. Confirm that the display is using the console’s normal aspect ratio and that no overscan, zoom or compatibility mode was enabled for that HDMI input. If the defect appears only after forced conversion, keep native SDR for that game and investigate the display input separately.
Gray blacks, crushed shadows or clipped highlights
These symptoms indicate a mismatch between the converted signal and the display’s tone map or black-level range. Compare the same dark and bright scenes in native SDR. If detail returns immediately, do not keep the conversion merely because colors look more intense.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsOnly one game looks wrong
Game support is not uniform. On Xbox, Auto HDR is limited to supported titles; on PS5, Always On applies conversion broadly. Treat the problem as title-specific: keep the global default that behaves correctly for most games and make an exception only when a particular title survives the comparison without visible defects.
Recommended settings by situation
| Your situation | Recommended starting point | Reason |
|---|---|---|
| You want the most faithful SDR image on PS5 | On When Supported | Non-HDR games remain in SDR as authored |
| You enjoy a brighter converted look on one PS5 game | Test Always On for that game | Conversion is a preference choice, not a universal improvement |
| You play backward-compatible games on Xbox Series X|S | Keep HDR capability available | Supported titles can receive Auto HDR enhancements |
| Your display shows washed-out SDR with HDR enabled | Return to native SDR and recalibrate | Washed-out output signals a tone-mapping or preset mismatch |
| You switch between several displays | Use each display’s own SDR and HDR presets | Panel brightness and tone mapping vary by model |
Bottom line for PS5 and Xbox owners
On PS5, leave HDR on On When Supported unless a direct, scene-by-scene comparison proves that Always On looks better on your display without losing detail. On Xbox Series X|S, leave HDR capability enabled if you want Auto HDR for supported older games, but judge each title rather than assuming every SDR game benefits. Native SDR remains the dependable baseline; conversion is an optional display preference whose success depends on the game and the screen.
