solderic.com VA (Vertical Alignment) panels typically offer deeper blacks and higher contrast ratios, making them ideal for dark room viewing, while IPS (In-Plane Switching) panels provide better color accuracy and wider viewing angles, reducing color shift and glow when viewed off-center. Understanding the differences between VA and IPS glow can help you choose the best display for your needs; read on to explore how these panel types impact your viewing experience.
Comparison Table

| Black Levels | Deep, true blacks | Grayish blacks with slight glow |
| Viewing Angles | Narrower (~150deg) | Wide (up to 178deg) |
| Color Accuracy | Good, but less consistent | Excellent, vibrant colors |
| Response Time | Slower (typically 4-8 ms) | Faster (typically 1-5 ms) |
| IPS Glow Effect | Minimal to none | Noticeable, especially in dark scenes |
| Use Case | Best for dark room viewing and contrast-focused use | Best for color critical tasks and wide viewing angles |
Introduction to VA and IPS Panel Technologies
VA panel technology offers deeper blacks and higher contrast ratios compared to IPS panels, making it ideal for dark room environments and multimedia consumption. IPS panels provide superior color accuracy and wider viewing angles, preferred for tasks requiring precise color reproduction such as graphic design and professional photo editing. Your choice between VA and IPS depends on whether you prioritize contrast performance or color consistency in your display.
What is IPS Glow?
IPS Glow is a visual effect commonly seen on IPS (In-Plane Switching) LCD panels where a soft haze or glow appears around the corners of the screen, especially visible in dark scenes or low-light environments. This occurs because of the way light leaks through the panel's layers at wider viewing angles, causing a slight luminance bleed that reduces contrast and color accuracy. While VA (Vertical Alignment) panels exhibit better contrast with deeper blacks, they do not suffer from IPS Glow, making the phenomenon a key differentiator between these two LCD technologies.
What is VA Glow?
VA Glow refers to a characteristic light leakage effect seen in Vertical Alignment (VA) LCD panels, where the screen exhibits uneven brightness or a subtle glow, especially in dark scenes or off-angle viewing. This phenomenon occurs due to the way liquid crystals align vertically and allow light to pass through unevenly when viewed from certain angles. VA Glow is distinct from IPS Glow in that it typically appears as a mild haze or light bleed around the edges, affecting contrast and black levels in VA displays.
Key Differences Between VA and IPS Glow
VA panels exhibit higher contrast ratios and deeper blacks but suffer from more pronounced glow, especially in dark scenes viewed at off-angles. IPS glow appears as a subtle halo around the edges of the screen, caused by the panel's liquid crystals allowing light leakage, affecting color accuracy and viewing comfort. Understanding these key differences helps you choose the right display technology based on your preference for contrast versus color consistency.
Causes of IPS and VA Glow Issues
IPS glow is caused by the way light leaks through the liquid crystal alignment at wide viewing angles, resulting in a noticeable silver or white haze around the screen edges. VA glow, on the other hand, stems from the inherent slow response and higher off-angle light diffusion of VA panels, causing dark halo effects and color shifting. Both glow issues are exacerbated by panel design and backlight technology, affecting image quality differently based on the LCD type.
Impact on Image Quality: VA vs IPS Glow
VA panels typically exhibit deeper black levels and higher contrast ratios, enhancing image depth and overall picture quality. IPS glow, characterized by a subtle haze around dark areas on IPS displays, can reduce perceived contrast in low-light scenes and affect visual clarity. The impact on image quality makes VA panels preferable for dark room viewing, whereas IPS panels excel in color accuracy and viewing angles despite the glow.
Viewing Angles: How Glow Affects Each Panel
Viewing angles significantly impact the perception of glow on VA and IPS panels, with IPS panels generally offering wider, more consistent viewing angles that reduce the appearance of glow. VA panels exhibit stronger glow when viewed off-center due to their narrower viewing angles, causing uneven brightness and color shifts. This makes IPS displays preferable in environments where screen visibility from multiple angles is critical, while VA panels may be better suited to direct, centered viewing.
Gaming Experience: VA vs IPS Glow
VA panels offer deeper contrast and darker blacks, enhancing immersion in dark gaming environments, while IPS panels exhibit IPS glow, which can reduce image consistency in low-light scenes. IPS glow may cause distracting glare around the edges during fast-paced games, whereas VA panels maintain more uniform brightness, improving visual comfort. Gamers seeking vivid colors and wider viewing angles might prefer IPS despite the glow, while those prioritizing contrast and reduced light leakage often favor VA panels.
Reducing Panel Glow: Tips and Tricks
Reducing panel glow on VA and IPS displays involves adjusting brightness and contrast to lower levels, which minimizes light leakage and enhances black depth. Using bias lighting behind the monitor can also reduce eye strain and make glow less perceptible by balancing ambient light. Applying software-based gamma correction tools or enabling dark mode in applications further helps to mitigate the impact of glow on image quality.
Which Panel is Right for You: VA or IPS?
VA panels deliver superior contrast ratios and deeper blacks ideal for dark room environments, while IPS panels provide wider viewing angles and more accurate color reproduction suited for graphic design and multimedia use. Gamers and movie enthusiasts may prefer VA displays for immersive visuals, whereas professionals who require color precision benefit from IPS technology. Choosing the right panel depends on your priorities: VA for contrast and depth, IPS for color fidelity and viewing flexibility.
