StarTech 2569-PRIVACY-SCREEN 25-Inch 16:9 Monitor Privacy Filter

The StarTech 2569-PRIVACY-SCREEN is a 25-inch, 16:9-format monitor privacy filter designed for workstations where on-screen data needs to stay visible only to the person seated directly in front of the display. At 21.8 x 12.3 inches and weighing just 3.5 oz, it attaches to the front of the monitor without tools, making it a practical fit for open-plan offices, security operations centers, financial workstations, and any shared-space environment where visual eavesdropping is a concern.

Overview

Privacy filters work by limiting the viewing cone of the display. The 2569-PRIVACY-SCREEN restricts visible content to a ±30-degree horizontal viewing angle — meaning anyone seated more than 30 degrees off-center from the screen sees a darkened, unreadable surface. That narrow cone is the core security mechanism here, and it does its job without requiring software configuration or network integration. Attach it once, and the physical layer of screen privacy is in place for every session. For organizations managing surveillance workstations or sensitive data terminals, this is a cost-effective and low-maintenance complement to logical access controls.

Key Features

• ±30° Viewing Angle Restriction: Anyone outside that 30-degree cone from center sees a blacked-out screen — not a degraded image, but effectively no image. In an open-plan security operations center or a finance desk in a busy office, this eliminates shoulder-surfing without any IT configuration.
• 21.8 x 12.3-Inch Panel Sizing: Precisely cut for 25-inch 16:9 displays. Correct sizing matters — a filter that overhangs or underlaps the active display area leaves gaps where screen content can be seen from the side. Verify your monitor measures 25 inches diagonally at 16:9 before ordering.
• 60% Light Transmittance: At 60%, the filter passes enough backlight that the display remains comfortably readable at normal brightness settings for the direct-view user. Lower-transmittance filters darken the screen significantly for the primary user too — 60% is a reasonable midpoint between privacy and usability for most commercial monitors.
• Anti-Glare Surface: The matte anti-glare coating reduces reflections from overhead lighting and windows — a common issue on glossy monitors in bright office environments. This is separate from the privacy function but practically useful in any deployment with mixed or strong ambient lighting.
• Blue Light Reduction: The filter includes blue light attenuation, which reduces the high-energy visible light emitted by LED-backlit displays. For operators who spend long shifts at a security console or trading desk, this can reduce eye strain over the course of a workday.
• Front-of-Monitor Attachment: Installs directly to the front bezel of the monitor — no drilling, no permanent modification. At 0.4mm thin and 3.5 oz, it adds no meaningful weight or depth to the display setup. Removal and re-attachment is straightforward if the monitor needs to be repositioned or replaced.
• 2-Year Manufacturer Warranty: StarTech backs the 2569-PRIVACY-SCREEN (often searched as 2569 PRIVACY SCREEN) with a 2-year warranty, which is standard for this product class and appropriate for a passive optical accessory with no moving parts or electronics.

Integration and Compatibility

This is a passive optical accessory — there is no software driver, no firmware, and no network component. It is compatible with any 25-inch 16:9 monitor regardless of brand or operating system. The only compatibility check required is physical: confirm your display is 25 inches diagonal at a 16:9 aspect ratio. Ultrawide (21:9) and other non-standard aspect ratios will not fit correctly. The filter is well suited for use with NVR and VMS workstations, financial terminals, HR systems, legal workstations, and any screen handling personally identifiable information (PII) in a shared or public-facing space. For organizations deploying IP camera systems with live-view monitoring consoles, pairing privacy filters with operator workstations adds a simple, non-IT-dependent layer of operational security. If you are equipping multiple workstations, review the full StarTech accessory catalog for size variants covering other display dimensions.

Frequently Asked Questions

Q: What monitor size does the 2569-PRIVACY-SCREEN fit?

A: It is sized for 25-inch diagonal monitors with a 16:9 aspect ratio. The filter panel measures 21.8 x 12.3 inches. Ultrawide (21:9) or other non-16:9 monitors of the same diagonal measurement will not be correctly covered.

Q: How wide is the private viewing zone — can a nearby colleague still see the screen?

A: The filter restricts the visible viewing angle to ±30 degrees from center. Anyone seated or standing more than 30 degrees off-axis will see a darkened, unreadable screen. A colleague seated directly beside you at less than 30 degrees offset may still have partial visibility depending on exact positioning.

Q: Does the filter noticeably darken the screen for the primary user?

A: The 2569-PRIVACY-SCREEN has a 60% light transmittance rating, meaning it passes 60% of the display's backlight. The primary user will notice a moderate reduction in brightness compared to using the monitor unfiltered, but most commercial monitors have more than sufficient brightness headroom to compensate by adjusting the display's brightness setting.

Q: Does it require any tools or adhesive to install?

A: No. The filter attaches to the front of the monitor bezel without tools, adhesive, or permanent mounting hardware. It can be removed and reinstalled as needed without leaving residue or marks on the display.

Q: What is the warranty on the 2569-PRIVACY-SCREEN?

A: StarTech provides a 2-year manufacturer warranty on this product.

Q: Does the blue light filter affect color accuracy for design or imaging work?

A: Blue light reduction filters alter the color temperature of the display, shifting it slightly warmer. For security monitoring, finance, or general productivity use this is generally a non-issue. For color-critical work such as photo editing or graphic design, the color shift may be undesirable and a non-tinted privacy filter would be more appropriate.

The spec that drives every purchasing decision on the 2569-PRIVACY-SCREEN is the ±30-degree viewing angle. In practice, that means anyone more than roughly an arm's length to the side of the primary user — at typical desk spacing — sees nothing usable on the screen. For security operations centers running live camera feeds or case management software, that is a meaningful physical control that does not depend on IT policy enforcement or user behavior.

Technical Highlights:

• ±30° Viewing Angle: Translates to a tight privacy cone for open-plan environments — effective shoulder-surf prevention with no configuration required.
• 60% Light Transmittance: High enough that the primary user does not need to push monitor brightness to uncomfortable levels to compensate, which matters on long-shift monitoring stations.
• 3.5 oz / 0.4mm Profile: Virtually no added weight or depth — relevant when monitors are on articulating arms where balance and extension limits are factors.

Deployment Considerations:

• Confirm your monitor is exactly 25-inch diagonal at 16:9 before deploying — the 21.8 x 12.3-inch panel is sized specifically for this geometry, and an incorrect fit leaves edges of the active screen unprotected from side viewing angles.
• The 60% transmittance will noticeably reduce perceived brightness compared to an unfiltered display. Budget for a monitor with at least 300 nits peak brightness in a well-lit office environment to maintain comfortable viewing for the primary user after the filter is applied.

The 2569-PRIVACY-SCREEN is the right fit for a staffed security operations console or an HR/finance workstation in an open-plan office where visual data exposure is a compliance concern — not the right choice for a color-critical imaging workstation where the blue light shift would interfere with accurate display work.
