OLED burn-in is real but rare on the 2025 Samsung S90F. Modern QD-OLED panels combined with Samsung's automated panel care features handle most use cases. Here's what actually moves the needle on burn-in risk — and what's marketing.

Quick answer

Pixel Shift: Settings → All Settings → General & Privacy → Panel Care → Pixel Shift ON
Logo Brightness: Settings → All Settings → General & Privacy → Panel Care → Adjust Logo Brightness ON
Pixel Refresh: runs automatically when TV detects 4+ hours of use; don't unplug during the cycle
Screen Saver: Settings → All Settings → General & Privacy → System Manager → Screen Saver: 5 minutes
OLED Care reminder: appears every ~2,000 hours of use; do not skip — let it run the full 8-minute Panel Refresh

Real-world risk on the S90F

Samsung's QD-OLED panel uses red, green, and blue subpixels (no separate white subpixel like LG's WOLED). Blue OLED material degrades fastest. In normal mixed viewing — sports, movies, streaming, gaming — burn-in is essentially nonexistent on a properly configured S90F over 5+ years.

The risk increases sharply when:

The same static logo (news ticker, channel watermark, sports scoreboard) is displayed for 8+ hours daily
The TV runs at OLED Brightness 100 with peak HDR content for extended periods
Game HUD elements (minimaps, health bars, ammo counters) sit at the same screen position for 100+ hours of gameplay
The TV is unplugged before automatic Pixel Refresh cycles can complete

Settings that actually matter

Pixel Shift (essential)

Settings → All Settings → General & Privacy → Panel Care → Pixel Shift: ON

Pixel Shift moves the entire image by 1-2 pixels every few minutes. You won't notice it. Static elements (logos, HUDs) get distributed across multiple subpixels rather than burning into one. This is the single most effective burn-in prevention feature. Leave it ON permanently.

Adjust Logo Brightness (essential for cable/sports viewers)

Settings → All Settings → General & Privacy → Panel Care → Adjust Logo Brightness: ON

The TV automatically detects static logos in the upper corners (network watermarks, sports scoreboards) and dims them slightly. Visually subtle; meaningfully reduces uneven wear on those pixels.

Screen Saver timeout

Settings → All Settings → General & Privacy → System Manager → Screen Saver: 5 minutes

After 5 minutes of paused content, the TV displays a moving screensaver. Critical for streaming services that pause indefinitely (Netflix's "Are you still watching?" screen sits at full brightness for ages).

OLED Brightness in HDR

Settings → All Settings → Picture → Expert Settings → Brightness: 35-45 in HDR

Counterintuitive: HDR doesn't need maximum OLED brightness. The S90F's Filmmaker Mode and HDR10+ Adaptive auto-tone-map already; cranking brightness to 50 (max) just accelerates panel wear without improving picture quality.

Standby Pixel Refresh — let it run

When you turn off the S90F via the remote (not unplug), it runs background pixel calibration cycles for 5-10 minutes. After every ~2,000 hours of use, a longer 8-minute Panel Refresh runs automatically.

Critical: if you unplug or kill power before the cycle completes, the panel can't compensate for accumulated wear. If you're going on vacation, leave the TV plugged in. The standby draw is under 0.5 watts.

Settings that don't matter (or matter less than you think)

Energy Saving

Setting Energy Saving to "High" reduces overall brightness and looks bad — but doesn't actually meaningfully reduce burn-in risk vs. a properly tuned brightness level. Skip this; tune OLED Brightness instead.

Picture Mode

"Standard," "Movie," "Filmmaker," "Game" — these affect picture quality, not burn-in risk. Pick the mode that looks best for your content. Filmmaker Mode runs at lower brightness by default but it's not a burn-in prevention feature.

"Pixel Cleaner" or third-party screen-shifters

Don't install third-party utilities. The S90F's built-in panel care is more sophisticated than any third-party tool, and external utilities can interfere with the TV's wear-tracking algorithms.

Gaming-specific advice

If you game 4+ hours daily on the S90F:

Vary your games. Different titles have different HUD positions. Switching games once a week distributes wear.
Lower OLED Brightness in Game Mode to 40-50. Reduces blue subpixel stress without visible quality loss.
Hide the HUD when possible. Some games (Cyberpunk 2077, Red Dead Redemption 2) let you fade or disable static UI elements.
Take 10-minute breaks per hour. Lets the panel cool and reduces continuous wear on bright HUD pixels.

Streaming-specific advice

If you watch a lot of news or sports with static logos:

Use the picture zoom or 4:3 crop occasionally. Shifts the watermark position.
Don't pause indefinitely on Netflix/YouTube static screens. The 5-minute screen saver handles this if you've enabled it.
Avoid running cable news as background "ambient TV" for 8+ hours. This is the single highest-risk usage pattern for any OLED.

What burn-in looks like and what to do

Early burn-in shows as ghost images of static elements (a CNN logo faintly visible on white screens, a video game minimap visible during cutscenes). It's typically visible only on flat color backgrounds.

If you see early signs:

Run Panel Care → Pixel Refresh manually (Settings → All Settings → General & Privacy → Panel Care → Pixel Refresh). This runs an 8-minute calibration that can clear mild image retention.
Vary your viewing habits for 1-2 weeks.
If retention persists after multiple Pixel Refresh cycles, contact Samsung warranty support — burn-in is covered for 1 year on most S90F purchases (verify your specific receipt and retailer warranty terms).

Don't unplug during a Pixel Refresh

The single most common preventable burn-in cause is interrupted Pixel Refresh cycles. The TV runs them automatically when you power off via the remote, but only if it's still receiving power.

If you have your TV plugged into a smart plug or power strip that you turn off at night — stop. Plug the TV directly into a wall outlet (or a surge protector that stays on) and let the standby cycles complete. The energy savings are negligible; the panel wear cost is significant.

FAQ

Is QD-OLED more or less prone to burn-in than WOLED (LG)? Both are vulnerable to similar mechanisms. Independent long-term testing (RTINGS) suggests QD-OLED's red and green subpixels wear at slightly different rates than blue, producing different burn-in patterns than WOLED. In normal mixed-content viewing, both technologies are reliable for 5+ years.

Will Samsung warranty cover burn-in? Samsung covers burn-in for 12 months on most retail S90F purchases as of 2026. Verify with your specific retailer; extended protection plans may extend this to 2-3 years.

Should I leave the TV on at low brightness when I'm away? No. Power it off via the remote so the panel care cycles run. Leaving it on at low brightness adds wear without benefit.

Can I disable Pixel Shift if I see the image moving? You shouldn't be able to see it. If you do, the setting may be misconfigured — try toggling it off and on again. Don't leave it disabled long-term.
