If you are in the market looking for a new computer monitor, you may have across the terms IPS (in-plane switching) and AH-IPS (Advanced High-Performance IPS).
This is what this post is about.
I will cover what are IPS and AH-IPS monitors and the differences. Let's get into into it.
The Difference Between AH-IPS and IPS Panel Technologies
The difference between AH-IPS (Advanced High Performance IPS) monitors and IPS (in-plane switching) is that AH-IPS is a type of IPS technology that was launched by LG in 2011. When you see a monitor marked AH-IPS panel type it means the display is by LG.
AH-IPS panel type is not just found on LG monitors, Its also found on other monitor brands such as AOC, ViewSonic, ASUS, Lenovo among others. Apart from AH-IPS, other variations of IPS technology include:
- H-IPS, E-IPS, and P-IPS by LG
- S-IPS - by Hitachi
- Plane to Line Switching (PLS) – Samsung’s form of IPS
- AHVA – AUO form of IPS
- IPS-ADS - by BOE
Here are a few ah-ips monitors
AH-IPS is an upgrade version IPS panel technology by LG. IPS is one of the four main types of panel technologies. The other types of include TN (Twisted Nematic), OLED, and VA. All these panel types are part of the widely known LCD panel technology.
But does it matter what panel technology a monitor has? Yes, it does.
A monitor’s panel technology is a key element since it highly affects what it can do and the uses it is best suited for. Moreover each monitor panel has its fair share of pros and cons.
However, choosing the right type of monitor to purchase largely depends on personal needs and preferences as well as your intended use. After all avid gamers, programmers, graphic designers, office workers and writers all have different needs. This is the reason why each type of display is designed for a different usage scenario.
So between AH IPS and IPS, which panel is the best for you?

IPS or in-plane switching panels were designed to handle the limitations of the TN panels, which were quite popular in the 1980s. The limitations included low production of quality color and dependence of strong viewing angle.
IPS technology involves leveraging liquid crystals by arranging and switching them in a parallel form between the glass substrates to produce rich colors. In addition, the panels can shift horizontally to create ultra-wide and better viewing angles as wide as 178 degrees. They are certainly incredible when it comes to expansive viewing angles and color performance.
IPS monitors remains to be among the best display panel of choice for people looking for consistent and accurate color. So if you are a CAD engineer, graphic designer, a pro photographer, or video editor you can never go wrong with an IPS monitor.
The super-wide viewing angles are designed to produce exceptional color even when viewing from different angles without the image shifting in terms of contrast and colors.
IPS monitors can be categorized into different variations S-IPS (Super In-Plane Switching), H-IPS (Horizontal In-Plane Switching), e-IPS (Enhanced In-Plane Switching) and P-IPS (Performance In-Plane Switching) and PLS (Plane-to-Line Switching).They are all known as IPS-type panels since they are relatively similar with slight differences. They all deliver major benefits that come with IPS monitors including super-wide viewing and outstanding color. Let’s have a look at the most sought-after features including image quality, response time and refresh rate.
Image Quality for IPS monitors
This involves the colors that the monitor can display, viewing angle as well as the contrast between dark and light. IPS monitors have a high color gamut, which means that they produce realistic graphics thanks to the wide viewing angles. As a result, they give sharp images even if you are not in front of the monitor, for instance when several people are using the screen at the same time.
The only downside when it comes to image quality is the IPS glow. This is mostly experienced when watching dark content and images in a dark room. In this case, you can spot glowing light at the corners of your monitor, which is caused by excess light that passes through the IPS panel. On the flip side, the glow is tolerable and can only be distracting in some rare cases as a result of poor quality control.
In addition, IPS panels have a low contrast. For example, a standard IPS screen has a contrast ration of 1000:1.
Refresh rate for IPS monitors
This is the number of frames per second that a monitor can compute, indicated in Hz. Most common gaming monitors have a refresh rate ranging from 75Hz TO 144Hz, although a higher numbers delivers smoother images. However, IPS displays tend to have a low refresh rate but with new innovations IPS screens with up to 144 Hz refresh rate are now in the market.
Response time for IPS screens
This is the time taken for a black pixel to change to white and back again. A screen with an extremely high response speed can experience ghosting also known as motion blurring especially when playing fast-paced games. You can notice this when vague streaks move behind a fast action object.
IPS screen have a response time of 4 milliseconds, which is hard to notice so you don’t have to worry about motion blur and ghosting with IPS panels unless you a hardcore FPS player. And since the panels keep on getting better, response times have advanced such that you can now find IPS screens with two or one milliseconds response speed. As a result, they have become more popular among gamers.
Another impressive feature of IPS is their ability to work seamlessly with professional color techs such as Adobe RGB because the monitors can deliver more display colors which enhances color accuracy.
- Exceptional color consistency and accuracy
- Best and maximum viewing angles
- Offers higher resolutions
- Offers sufficient response times for most users
- eliminates color and contrast shift
- Static contrast ration is below average (for example, black colors tend to appear grayish)
- High consumption of power
- Can potentially produce white glow when watching dark content, which is common with low priced IPS monitors
AH-IPS (advanced high-performance IPS) panel technology is a modified version of IPS monitors by LG that was launched in 2011. AH-IPS is an upgrade designed to boost saturation by up to 30 percent to make colors more vibrant.
They are high-performance thanks to the advanced technology, which helps deliver extra-wide viewing angles. As a result, you can view the screen from any angle up to 178/178 degrees, which is ideal for users sitting in different postures.
Unlike standard IPS panels, AH-IPS panels offer incredibly crisp image with crystal-clear colors. This makes them perfect for web browsing, photos, and movies as well as for professional applications that require more accurate and consistent color representation.
Besides that, AH-IPS panels only consumes energy when displaying dark or bright images, thus helps reduce power consumption. The panels also have increased resolution to create impressive contrast, while reducing the level of blinking to almost zero. This way, users have lower chances of developing eye aches, watery eyes even after using the monitor for prolonged hours.
Verdict IPS vs. AH-IPS
Choosing the best panel between AH-IPS and IPS can be a difficult task. Each panel have its fair share of advantages and drawbacks. Before making the final decision, you need to carefully think about the intended use of the screen. If you are a gamer, graphic designer or your profession requires colo-critical application, you can never go wrong with AH IPS panel. This panel has a quick response time, give clear images. So if you are looking for a high resolution monitor, AH IPS is your perfect fit.
On the other hand, if you are looking for a panel ideal for higher-level business purposes or for home use, you can go for IPS panel. It has almost all the features of the AH IPS but at a lower cost.
