Within the category of LCD monitors are three main panel types, each offering some advantages and disadvantages: TN, VA and IPS.

Liquid crystals have a natural relaxed state. When a voltage is applied they rearrange themselves to block certain light waves. If left with the same voltage for an extended period of time (e.g. displaying a pointer or a taskbar in one place, or showing a picture for an extended period of time), the liquid crystals can develop a tendency to stay in one position. This ever-so-slight tendency to stay arranged in one position can throw the requested color off by a slight degree, which causes the image to look like the traditional "burn-in" on phosphor based displays.

The cause of LCD image retention is different from phosphor aging as in CRTs, but the visual phenomenon is the same: uneven use of display pixels. Slight LCD image retention can be recovered. When severe image retention occurs, the liquid crystal molecules have been polarized and cannot rotate in the electric field, so they cannot be recovered.

If you're looking for the best monitor for your eyes, you'll want to look for features like backlight flickering prevention and Low Blue Light (LBL) technology. LBL is high energy, low wavelength light on the visible light spectrum that can cause eye strain and damage your retinas over time. Additionally, LBL can impact your Circadian rhythm (your body's internal clock), affecting your ability to fall asleep at night. Many modern computer monitors have a low blue light filter, but it may be called "Eye Saver" or "Reader" mode.

The cause of this tendency is unclear. It might be due to various factors, including accumulation of ionic impurities inside the LCD, impurities introduced during the fabrication of the LCD, imperfect driver settings, electric charge building up near the electrodes,[1][2] parasitic capacitance,[3] or a DC voltage component that occurs unavoidably in some display pixels owing to anisotropy in the dielectric constant of the liquid crystal.[4]

Another important factor in reducing eye strain is viewing angle availability. Height and swivel adjustments go a long way in increasing viewing angles. You could also purchase an arm mount to ensure you can position your monitor optimally.

Although nearly all LCD monitors have LED backlighting today, here are the pros and cons of older CCFL-lit LCD monitors vs. LED LCD monitors for comparison's sake.

QLED monitors use nanoparticles called quantum dots that act as color and light filters. Millions of quantum dots can produce stunning displays of brightness and color. They are LED monitors, but the quantum dots allow for richer color and finely adjustable brightness. QLEDs offer full color saturation even in brightly-lit rooms. But the downside is that QLEDs have to dim their backlights for dark colors, which makes it difficult to produce a pure black effect like on an OLED. QLED monitors are also best viewed from dead center, so they might not be the best choice for workspaces that need wide viewing angles

Image persistence, or image retention, is a phenomenon in LCD and plasma displays where unwanted visual information is shown which corresponds to a previous state of the display. It is the flat-panel equivalent of screen burn-in. Unlike screen burn-in, the effects are usually temporary and often not visible without close inspection. Plasma displays experiencing severe image persistence can result in screen burn-in instead.

What's the difference between LCD and LED monitors? Which is better for your eyes? Which better for gaming? Here's how to decide which is right for your needs.

Liquid Crystal Display (LCD) monitors feature a layer of liquid held between two pieces of polarized glass. The LCD monitor does not produce its own light. The electric current aligns the crystals in the liquid layer, which allows or blocks light, depending on what color it's supposed to display. LCD monitors historically have CCFL backlighting but commonly have LED backlighting today.

Monitors with full-array lighting have diodes evenly distributed behind the monitor, providing even lighting across the entire screen. Monitors with edge lighting only have LEDs around the perimeter of the monitor and the light is spread with a sheet of plastic to distribute the light evenly, which saves money for the manufacturer and ultimately for you.

As you try to make the best choice for your professional and personal monitor needs, consider what features are necessary and most important to improving your work space and/or your gaming space. In most cases, an LED monitor holds the advantage due to its longer lifespan, better picture quality, thinner design, fast response time and more environmentally friendly construction. These qualities offset the higher initial price point that might have you considering an LCD option. But if you are looking for something cheaper just to get you through a workday with some spreadsheets, the LCD could be for you.

Finally, some monitors adjust their brightness dynamically according to the ambient lighting in the room. For instance, if there is low light, the monitor will decrease its brightness automatically, which helps reduce eye strain. Monitors from some brands also have brightness settings you can adjust depending on what you're using the monitor for (work, movies, gaming, etc.).

When it comes to gaming, LED LCD monitors also win against CCFL LED monitors. However, what type of LED LCD monitor you should get depends on the main genre of gaming you're looking to do (and how competitive you are).

LED monitors use LEDs (light-emitting diodes) to light up the screen, which are basically very small bulbs, like mini Christmas lights. The arrangement of the LEDs behind the screen varies--monitors feature either full-array LED backlighting or edge lighting. Some high-performance, modern monitors have mini-LEDs, which allows for even finer lighting control.

Image persistence can be reversed by allowing the liquid crystals to relax and return to their relaxed state, such as by turning off the monitor for a sufficiently long period of time (at least a few hours). For most minor cases, simply continuing to use the computer as usual (and thus allowing other colors to "cover" the affected regions) or turning off the monitor for the night is more than enough. One strategy for users looking to avoid image persistence artifacts is to vary the activities performed on a computer to avoid static colors and hide elements on the screen which are displayed perpetually (such as an OS's Taskbar). Another strategy is the usage of a screensaver to help during times the computer is left unattended. Covering the entire display area with pure white for an extended period of time is also a useful proactive solution.[5][6]

Image persistence can occur as easily as having something remain unchanged on the screen in the same location for a duration of even 10 minutes, such as a web page or document. Minor cases of image persistence are generally only visible when looking at darker areas on the screen, and usually invisible to the eye during ordinary computer use.

Comparing LED (light-emitting diode)  to LCD (liquid-crystal display) monitors directly is a misunderstanding of their definitions. "LED" and "LCD" refer to different aspects of monitor technology (the backlighting and display, respectively). If you're short on time, your takeaway should be all monitors that have LED backlighting are LCDs, but not every LCD uses LED technology to illuminate the screen.

Want to get more granular in your choice of LEDs? New screen technology typically hits the TV market first, but trickles down to computer monitors in short time. Two new such monitor types are OLED — Organic Light Emitting Diode — and QLED — Quantum Light Emitting Diode.

Between LED LCD monitors and CCFL LCD monitors, LED wins hands down in almost every respect besides cost. However, you'll probably end up coming out ahead with an LED LCD monitor in the long run due to their longer average lifespan.

Every pixel in an OLED monitor is its own miniature LED light. Unlike regular LED monitors, OLED monitors aren’t technically backlit because each pixel produces its own light and color. If an individual pixel doesn’t receive electricity, it will appear dark. OLED technology offers amazing picture contrast as a result. And because each pixel is individually lit, OLED has an incredibly low response time — 0.1 millisecond — that is great for crisp images and gaming.

In the past, most LCDs were backlit with cold cathode flourescent lamps (more commonly known as CCFL backlighting). Now, most modern LCD monitors are lit with LEDs. LED-lit LCD monitors are significantly thinner, lighter and use less power than their CCFL predecessors. Additionally, LED diodes last longer than CCFL bulbs. You won't see a huge impact in image quality with CCFL LCDs vs LED LCDs, though, but you may notice LEDs light the screen more evenly than CCFL.

Some computer monitors, known as LCD HDR (high dynamic range) displays, feature local LED dimming. This capability allows you to dim parts of the screen depending on what's being shown. This gives you inky blackness and brighter, more dynamic color, rather than the entire screen being evenly backlit all the time. With mini-LED monitors, this capability is enhanced since the diodes are about 1/5th the size of standard LEDs, giving you more precise dimming capability.

If you are spending a lot of time in front of a monitor, it is important to make an informed decision when purchasing a new one. High-quality monitors can relieve eye strain, improving employee experiences or getting you further in your favorite game. So, as your system needs to be updated, the question becomes: is an LED or LCD monitor better? Which monitor is better for eyes? Which monitor is better for gaming? What is the difference between LCD and LED monitors, if any? Consider these key points to determine which technology makes sense for your computer use.

A full-array LED LCD monitor with an IPS panel is best for the broad swath of gamers out there due to the great color accuracy, dimming capability and ample available viewing angles. Even better if you can afford an HDR monitor or a curved monitor!

However, if you're a hardcore FPS gamer who wants to compete on a high level, you should consider purchasing an LED LCD monitor with a TN panel. When it comes to FPS gaming, response time matters. You'll find that LED monitors with TN panels have the lowest average response times (some even under 1ms), which means the shortest amount of time the screen takes to shift from one color to another. When your enemy is peeping around the corner, every millisecond counts.
