The Honest Answer

Yes, some people are having problems—but it's not universal. Since the Galaxy S26 Ultra launched, there's been a noticeable number of complaints about Privacy Display causing eye strain, headaches, and even nausea. But scroll through any Reddit thread about this, and you'll also find plenty of people saying "works fine for me."

So what's actually going on?

What People Are Experiencing

The complaints have shown up on Reddit, Samsung's community forums, and in reviews from TechRadar and Tom's Guide. Users describe:

• Eyes feeling tired or strained after using Privacy Display
• Headaches that develop during or after use
• Some people literally feeling nauseous or dizzy
• Text looking "fuzzy" or weirdly sharp
• A general sense that something's "off" about the display

One Redditor put it bluntly: "The new display is making me nauseous."

Why This Happens (The Technical Explanation)

The Flickering You Can't See

The S26 Ultra uses PWM dimming at 480Hz. To make the screen dimmer, it actually flickers on and off 480 times per second.

For most people, that's way too fast to notice. But some people's eyes or brains pick up on it anyway, causing problems. Here's the issue: competitors like HONOR run at 3,840Hz or higher, and OnePlus lets you turn PWM off entirely with DC Dimming. Samsung hasn't included that option.

Privacy Display Adds Complexity

When Privacy Display is on, the screen restricts viewing angles through additional processing. This can create subtle changes in how colors look and how text renders—especially near the edge of the "safe" viewing zone. Sensitive users pick up on these shifts.

What Samsung Says

Samsung has acknowledged the complaints but says most users are fine. They're not planning to add flicker-reduction features to the S26 series.

If You're Having Problems

A few things that help:

• Increase brightness – Higher brightness actually reduces how much the screen flickers
• Use Privacy Display selectively – Enable it only when genuinely needed, not all day
• Take breaks – Especially during extended use
• Test before buying – If you're sensitive to screens, test Privacy Display in a store first

The good news? With Privacy Display off, the S26 Ultra's screen is excellent with none of these issues. It's specifically the privacy feature that triggers problems for sensitive users.
