What Is IPS Glow And How Can I Reduce It?.. Do we know?...
Wondering why your newly bought IPS monitor seems to be glowing? This means you are experiencing a widely-known phenomenon called IPS glow. This is one of the very few disadvantages of buying this otherwise-great monitor. While you may enjoy how beautiful the pictures appear on your new screen, you might also notice this unfortunate effect. Some models might have worse cases of IPS glow while others are almost undetectable.
What is IPS Glow?
IPS glow is different from backlight bleeding. As the name suggests, this is a problem common with IPS monitors. It looks like the light is “glowing“ in some spots. It may appear that colours are distorted in these areas. However, the effect changes based on the angle you are looking at the screen, as well as how far you are from the monitor. This is directly due to the technology the monitors use, and the severity of the glow differs between different models.
On the other hand, backlight bleed is due to the light source found behind the monitor’s screen. Normally, an LCD blocks the light when it is not needed, leading to a black screen. When it is not blocked thoroughly, light bleeds through. This is called backlight bleeding and is usually seen around the edges of the screen. It will be like the screen has some light patches instead of a fully dark screen.
Both problems can be annoying, but it shouldn’t stop you from buying an LCD or IPS monitor. This is because the issue does vary from model and brand and it is most visible when the room is dark (and the brightness settings are set way up). The glow also seems a bit brownish, yellowish, greyish, or light bluish, but it may differ between individual units.
Can You Test A Monitor For IPS Glow?
Because this can be a problem common to IPS monitors, how can you be sure that your new screen will not have this problem? After all, if it is a serious issue, you can immediately return it instead of being stuck with a new IPS monitor with bad IPS glow.
To test it, open a full black screen on the monitor and dim all lights in the room (lamps, as well as light from outside). The darker the room is, the better you will be able to detect the IPS glow. You can also test the monitor in normal light, because some models have really serious issues with IPS glow that you can even see it when the room is brightly lit. When you see the glow in these conditions, then you really should consider having the monitor replaced or refunded.
What Happens When Your Monitor Has IPS Glow?
It happens very often that owners notice the IPS glow too late to return the monitors or have it replaced. Plus, in many cases, the glow is not that severe that you cannot do anything about it. Does your monitor have a mild case of IPS glow? Then you can try out these tricks to reduce it.
1. Increase The Ambient Lights
The darker the room, the more obvious the IPS glow appears. So the easiest thing to do is to brighten the room where the screen is being used. Plus, you can view the black levels of the gaming monitor, and the contrast appears more prominent.
2. Make The Right Monitor Adjustments
If you use your IPS monitor in a dark room, then you have to use the right monitor adjustments. This means to set it up at the right height and tilt. The best thing you can do is to open a test video in a darker environment, then adjusting the height and tilt until you find the right position where the glow is least visible.
3. Lower The Brightness
Many people set their screens at the highest brightness settings (or higher than 80 in the OSD) but setting this lower can have the biggest effect on IPS glow. The ideal setting is somewhere around 120 cd/m. It will be a change in the beginning, but you will easily get used to the new settings. Plus, your eyes will find a lower brightness better, and the contrast will improve.
4. Massage The Screen With A Microfiber Cloth
While this is not a proven fix, some people online promise that it helps. All you need is a microfiber cloth and massage the screen’s edges for about 20 to 30 minutes. It might not work on everyone, but trying it out wouldn’t hurt.
5. Set The Monitor A Little Bit Further
Increasing the distance between you and the screen may lead to the panel appearing smaller, but this is a good step if the IPS glow is really bothering you. You can even try mounting the monitor on the wall or just leaning back in your chair. For best results, go for a distance between 80 and 120 cm away from the monitor. The farther you are, the less you can see the glow.
6. Loosen The Panel Frame Construction
This is the most challenging step and should be done very carefully. And never use credit cards to loosen the panel frame to avoid making these two mistakes. The first is that you might end up losing the inner panel frame out of the metal, leading the outer panel frame (which is made of plastic) to push the inner panel against the outer one. The second possible mistake is that your credit card may lose some pieces of plastic, and these might get stuck in the inner panel frame. This may lead to more pressure on the panel and lead to backlight bleeding.
Should you have to live with IPS glow? Ideally not, especially if you end up buying a new screen with a bad case of that issue. You should always test any new monitor for defects and contact the manufacturer or seller as soon as possible while you can still return it or it is still under warranty. But if you do not have any major issues in the first weeks, then you might have a model that has no or an almost undetectable IPS glow. If it does come up, then you can try out these tricks to reduce it.
