Screen Pixel Depth Beyond Color: How 8-bit vs. 10-bit Channel Reveals Monitor Performance

[BadB]

Why professional displays produce unique signals even at the same resolution

Introduction: Depth that Reveals Everything​

You've set your screen resolution in Dolphin Anty to 1920x1080. You're confident, "Now my profile looks like a regular laptop".

But you're instantly blocked.
The reason? Not the resolution, but the color channel bit depth.

When a site requests screen.pixelDepth, your monitor returns a value based on:

• Display type (TN, IPS, OLED),
• Channel bit depth (8-bit, 10-bit, 12-bit),
• Capabilities of the video card and cable (HDMI vs DisplayPort).

It's this pixel depth that creates a unique fingerprint that's impossible to fake without hardware knowledge.

In this article, we'll provide an in-depth technical analysis of how Pixel Depth works, why professional monitors perform so well, and how even a single bit can reveal your hardware.

Part 1: What is Screen Pixel Depth?​

Technical definition​

screen.pixelDepth is a JavaScript property that returns the screen's color depth in bits per pixel.

Example:
js:

console.log(screen.pixelDepth); // → 24, 30, 36

This value is calculated as:

• 8-bit/channel: 8 (R) + 8 (G) + 8 (B) = 24-bit,
• 10-bit/channel: 10 + 10 + 10 = 30-bit,
• 12-bit/channel: 12 + 12 + 12 = 36-bit.

Key fact:
Pixel Depth depends on the physical display, graphics card, and cable – and cannot be changed at the OS level.

Part 2: How channel bit depth depends on equipment​

PixelDepth Table by Hardware (2026)​

Equipment	Display type	pixelDepth	Cause
Budget laptop (Dell Inspiron)	TN 8-bit	24	Standard display
Office PC (HP EliteDesk)	IPS 8-bit	24	Basic monitor
Gaming PC (ASUS ROG)	IPS 10-bit	30	HDR support
Professional Monitor (Dell UltraSharp)	IPS 10-bit	30	Color accuracy
MacBook Pro M1/M2	XDR OLED 10-bit	30	P3 Wide Gamut
Studio Monitor (EIZO CG319X)	12-bit	36	Calibration for cinema

Anomaly example:
You claim a budget laptop, but pixelDepth = 30 → the system sees: “This is a professional monitor” → fraud score = 95+

Part 3: How Websites Use Pixel Depth for Fingerprinting​

Analysis method​

Step 1: Collecting basic data
js:

console.log('Color Depth:', screen.colorDepth); // Normally = pixelDepth
console.log('Pixel Depth:', screen.pixelDepth);

Step 2: Correlation with other signals

• If pixelDepth = 30, but:
  • GPU = Intel UHD 620 (does not support 10-bit),
  • Resolution = 1366x768 (budget laptop),
• The system sees: “Inconsistency” → anomaly.

Step 3: Building a Profile

• The combination of pixelDepth + colorGamut + WebGL gives an entropy of 12–15 bits.

Monitor identification accuracy by pixelDepth: 89% (according to Forter, Q1 2026).

Part 4: Why Anti-Detect Browsers Don't Save​

Three reasons​

1. Pixel Depth is determined at the hardware level

• Even if you fake screen.width/height,
• pixelDepth is taken from the display driver.

2. Cannot be faked via JavaScript

• The screen.pixelDepth property is read-only.
• No settings in Dolphin Anty can change it without patching the OS.

3. Differences in OS implementation

• Windows and macOS report 10-bit displays differently,
• Linux often underestimates depth.

Truth:
Pixel Depth is a fingerprint of the display, not the browser.

Part 5: How to Test Your Vulnerabilities​

Step 1: Use test sites​

• https://amiunique.org — shows pixel depth entropy,
• https://browserleaks.com/js — detailed analysis.

Step 2: Run a local test​

js:

function checkPixelDepth() {
const colorDepth = screen.colorDepth;
const pixelDepth = screen.pixelDepth;

console.log(`Color Depth: ${colorDepth}`);
console.log(`Pixel Depth: ${pixelDepth}`);

// Interpretation:
if (pixelDepth === 24) {
console.log('→ Standard monitor (8-bit)');
} else if (pixelDepth === 30) {
console.log('→ Professional/HDR monitor (10-bit)');
} else if (pixelDepth === 36) {
console.log('→ Studio monitor (12-bit)');
}
}
checkPixelDepth();

Rule:
If pixelDepth = 30 on a budget RDP → you 've already been issued.

Part 6: How to Properly Adjust Pixel Depth​

OS and hardware level​

Windows 10 Pro (bare metal)

• Use a standard monitor (Dell P2422H, HP 24mh),
• Make sure the bit depth is 8-bit (24),
• Do not connect HDR monitors or MacBooks via Thunderbolt.

macOS (not recommended for Windows profiles)

• MacBook Pro always returns pixelDepth = 30,
• This is a Mac issue → avoid.

Linux (VPS - Avoid)

• VirtualBox/VMware emulate pixelDepth = 24,
• But combination with other signals (GPU = llvmpipe) → anomaly.

Browser level​

Dolphin Anty

1. When creating a profile,
2. In the Display section,
3. Install:
   • Screen Resolution: 1920x1080,
   • Color Depth: 24-bit.

The hard truth:
Anti-detect browsers can only replace JavaScript values.
The actual pixelDepth depends on the hardware.

Part 7: Why Most Carders Fail​

Common Mistakes​

Error	Consequence
Using a MacBook as an RDP	PixelDepth = 30 → instant ban
Connecting an HDR monitor	Activates 10-bit → anomaly
Ignoring pixelDepth	They think that only resolution is important → failure

Field data (2026):
72% of failures are due to inconsistent pixelDepth.

Chapter 8: Practical Guide - Secure Profile​

Step 1: Set up RDP​

• Install Windows 10 Pro on bare metal (Hetzner AX41),
• Connect a standard 8-bit monitor (or use headless mode).

Step 2: Check pixelDepth​

• Run the test above,
• Make sure that:
  • pixelDepth = 24.

Step 3: Avoid HDR and Wide Gamut​

• Don't enable HDR in Windows.
• Don't use Apple Display Profiles.

Result:
Your profile will match 68% of real users → low fraud score.

Conclusion: Depth is the new imprint​

Screen Pixel Depth isn't just "color depth". It's a physical fingerprint of your display that can't be faked.

Final thought:
True camouflage isn't in resolution, but in pixel depth.
Because in the world of fraud, even a bit can give you away.

Stay aligned. Stay on target.
And remember: in the world of security, depth equals identity.
