Analyze your monitor's DNA. Our studio detects native hardware resolution, pixel density (DPI), and audits your panel for sub-pixel defects using high-contrast diagnostic cycles.

Identify Dead Pixels and backlight leakage before your warranty period expires, saving on expensive repairs.
In the digital age, your screen is the window through which you view the entire universe. But not all windows are built equal. From the microscopic sub-pixels of an OLED panel to the complex scaling algorithms of a Retina display, your monitor has a unique technical signature. At Trust My IP, we’ve developed this Display Forensic Studio to help you understand the "Visual DNA" of your hardware.
Understanding metrics like Native Resolution, Aspect Ratio, and Pixel Density is no longer just for hardware geeks. Whether you are a creative professional ensuring color accuracy for a print campaign, a software developer building responsive UI, or a consumer checking a new laptop for defects, this diagnostic hub provides the authoritative intelligence you need. We don't just show you numbers; we help you interpret them using the same standards used by monitor manufacturers and cybersecurity researchers.
In this master guide, we will deconstruct the physics of the pixel, explore the impact of DPI Scaling on web performance, and provide a clinical roadmap for identifying and (sometimes) fixing panel defects like stuck pixels and backlight bleed.
When our tool reports a resolution of 3840 x 2160, it is counting the individual "light-bulbs" (pixels) that make up your display. The Native Resolution is the physical number of pixel rows and columns hard-wired into your panel. Using any other resolution (interpolation) results in a "fuzzy" or "blurry" image because the computer has to guess how to spread the image across the physical pixels.
The relationship between width and height—the Aspect Ratio—defines your digital workspace. In 2025, three standards dominate the professional market:
In the past, one pixel on the screen equaled one pixel in the software. This changed with HiDPI and Retina Displays. Manufacturers started packing more pixels into the same physical space to make text look "Printed" rather than "Digital."
In our report, notice the Device Pixel Ratio (DPR). If it says 2.0x or 3.0x, your browser is using multiple physical pixels to draw one "logical" pixel. This prevents icons from looking tiny on 4K screens while providing ultra-sharp edges.
Our Fullscreen Diagnostic is designed to flush out hardware defects that are often invisible during normal use. To perform a professional audit, darken your room and cycle through the test colors:
These appear as black dots on white backgrounds. They occur when the transistor fails completely. Expert Tip: If your monitor has more than 3-5 dead pixels, most manufacturers are legally required to replace the panel under warranty.
These appear as a single bright color (Red, Green, or Blue) on a black background. They happen when a sub-pixel gets "frozen." Unlike dead pixels, these can often be fixed by "Pixel Exercisers" that cycle colors rapidly.
Use the Pure Black test in a pitch-black room. If you see white "clouds" or light leaking from the corners of the screen, you are witnessing Backlight Bleed. While common in LED/LCD technology, excessive bleeding can ruin the contrast ratio and is considered a hardware defect in high-end gaming and professional monitors.
| Common Name | Pixel Count | Ideal Use Case |
|---|---|---|
| Full HD (1080p) | 1920 x 1080 | Office / Budget Gaming |
| QHD (2K / 1440p) | 2560 x 1440 | Competitive Gaming |
| 4K Ultra HD | 3840 x 2160 | Cinema / Photo Editing |
| 8K Extreme | 7680 x 4320 | Future Hardware |
**No.** A dead pixel is an isolated hardware failure in a single transistor. If you see a growing spot or a line, it’s not a dead pixel—it is likely a failing Ribbon Cable or a cracked internal layer of the panel, which is much more serious.
This is usually due to Sub-optimal Scaling. High-resolution screens need Windows "Scaling" (e.g., 150% or 200%) to make text readable. However, some older apps don't support "HiDPI" and will appear blurry. Use our tool to verify your native resolution matches your OS settings.
**Sometimes.** Unlike truly dead pixels, stuck pixels can occasionally be fixed by using specialized software that flashes Red/Green/Blue colors rapidly at 60Hz. This "massages" the liquid crystals back into place. For OLED screens, avoid this, as it can cause burn-in.
It is a technique used by operating systems (like ClearType) to increase the perceived resolution by using the individual red, green, and blue components of a pixel. This is why text looks smoother than standard shapes.
