What defines a Gamer monitor?
- Gamer monitors can have a different design, with elements such as RGB lighting.
- High screen refresh rates (120Hz, 140Hz, 240Hz) are also common features in Gamer monitors.
- The goal is to show the differences between monitor types.
- A comparative analysis will be made between three different monitors.
Types of panels
- The three types of panels analyzed are:
- TN Panel
- Painel VA
- IPS panel (the most popular)
Difference Between LCD and LED in Monitors
The difference between LCD and LED in monitors.
- All monitors mentioned are LCD.
- LED technology is present in the backlight of LCD monitors.
- Backlight is responsible for generating light to illuminate the monitor’s liquid crystal.
Monitor panel construction layers
The monitor panel construction layers.
- Backlight: LED layer that generates light to illuminate the liquid crystal.
- Polarizing layer: twists light to flow horizontally or vertically.
- TFT (Thin Film Transistor) layer: contains transistors that control the energy applied to the liquid crystal.
- Liquid crystal: material that modifies the passage of light based on the applied voltage.
TFT layer function and color control
The function of the TFT layer and how it controls the colors on the monitor.
- The TFT layer is responsible for managing the energy that powers the liquid crystal.
- This layer allows you to control colors and the passage of light on the monitor panel.
Passage of light through rods
How light passes through the rods in the liquid crystal.
- Rods are molecular structures present in liquid crystals.
- They allow light to pass between the polarizing plates, controlling its direction.
Functioning of polarizing plates
How polarizing plates work and how they twist light to allow it to pass through or block it.
- The polarizing plates have the function of twisting the light and making it fit into the second polarizing plate, thus allowing the image to be viewed.
- The twisting of the polarizing plates is responsible for directing the light appropriately so that it is possible to see the desired image.
Liquid Crystal Display Layers
The layers present in a liquid crystal display and their function.
- After the polarizing plates, there is a layer of liquid crystal that receives an electrical voltage to twist the light.
- Next is an RGB color filter layer, as liquid crystal is gray and needs this filtering to display colors correctly.
- Finally, there is a finishing layer of glass that protects the monitor. This combination of layers allows you to view images on the monitor.
Different Types of LCD Panels
T he three main types of LCD panels (TN, VA and IPS) and their distinct characteristics.
- TN (Twist Nematic) panels have faster refresh rates and are popular among gamers. However, they have disadvantages regarding color fidelity and viewing angles.
- VA (Vertical Alignment) panels offer better color reproduction and wider viewing angles, but may have lower refresh rates.
- IPS (In-Plane Switching) panels also have good color reproduction and wide viewing angles, as well as better response times compared to VA panels.
Monitor refresh rate
The concept of monitor refresh rate and its importance for different audiences.
- The refresh rate is measured in hertz (Hz) and represents the number of times an image is displayed per second.
- Os gamers geralmente procuram monitores com taxas de atualização mais altas para obter uma experiência mais suave.
- Profissionais que trabalham com design gráfico, fotografia e edição de vídeo valorizam monitores com maior fidelidade na reprodução das cores.
Painel TN – Vantagens e desvantagens
As vantagens e desvantagens do painel TN.
- O painel TN possui taxas de atualização mais rápidas, sendo preferido pelos gamers. No entanto, apresenta desvantagens em relação à fidelidade das cores e aos ângulos de visão.
- Ao visualizar o monitor a partir dos lados ou em ângulos diferentes, ocorre distorção nas cores, resultando em uma experiência visual menos precisa.
Diferenças entre os tipos de painéis LCD
As diferenças entre os três principais tipos de painéis LCD (TN, VA e IPS).
- Os painéis TN têm taxas de atualização mais rápidas, mas apresentam desvantagens em relação à fidelidade das cores e aos ângulos de visão.
- Os painéis VA oferecem melhor reprodução de cores e ângulos de visão mais amplos, mas podem ter taxas de atualização mais baixas.
- Os painéis IPS possuem boa reprodução de cores, ângulos de visão amplos e melhores tempos de resposta em comparação com os painéis VA.
Visão geral dos painéis de monitor
Os diferentes tipos de painéis de monitor e suas características, como ângulo de visão, taxa de atualização e fidelidade de cores.
Painel TN
- Os painéis TN são comumente usados em jogos competitivos.
- Eles têm um ângulo de visão limitado, geralmente entre 70 a 80 graus.
- Possuem alta taxa de atualização para melhor desempenho em jogos.
Painel VA
- Os painéis VA oferecem melhor ângulo de visão e cores do que os painéis TN.
- Têm uma taxa de contraste mais alta, o que resulta em imagens mais nítidas.
- São adequados para trabalhos relacionados a foto e design gráfico.
Painel IPS
- Os painéis IPS possuem o melhor ângulo de visão e reprodução precisa das cores.
- São amplamente utilizados em trabalhos que exigem fidelidade nas cores, como design gráfico.
- Geralmente têm menor taxa de atualização do que os painéis TN.
Comparação entre os tipos de painel
São comparadas as características dos diferentes tipos de painel, incluindo contraste, amostragem de cores e taxa de atualização.
Painel VA
- Possui melhor contraste do que os painéis TN e IPS.
- Tem boa amostragem de cores, mas não tão precisa quanto os painéis IPS.
- Geralmente tem menor taxa de atualização do que os painéis TN.
Painel IPS
- Oferece o melhor ângulo de visão e reprodução precisa das cores.
- Tem contraste semelhante ao dos painéis TN, mas pior do que os painéis VA.
- Geralmente tem menor taxa de atualização do que os painéis TN.
Painel TN
- Possui alta taxa de atualização, adequada para jogos competitivos.
- Tem menor ângulo de visão e reprodução menos precisa das cores em comparação com os painéis VA e IPS.
Considerações adicionais sobre os painéis
São abordados outros aspectos a serem considerados ao escolher um monitor, como preço e avanços tecnológicos.
- High refresh rate IPS monitors are becoming more common on the market.
- IPS monitors can have the same refresh rate as VA or TN panels, but they are often more expensive.
- Technology is advancing rapidly, making some features traditionally associated with certain panel types less relevant in practice.
Monitor TN
- The TN monitor has limited ability to display colors and color gamut.
- Shows 96% of the colors of the sRGB standard.
- Shows 76% of the colors of the P3 standard.
- Shows 71% of the NTSC standard colors.
- Shows 74% of the colors of the Adobe RGB standard.
Monitor with VA Panel
- The VA panel monitor shows a significant improvement in color reproduction compared to the TN monitor.
- Shows 100% of the sRGB standard colors.
- Shows 87% of the colors of the P3 standard.
- Shows 77% of the NTSC standard colors.
- Shows 82% of the colors of the Adobe RGB standard.
Monitor IPS
- The IPS monitor is considered the best type of panel for color sampling and fidelity.
- Shows 95% of the colors of the sRGB standard.
- Shows 76% of the colors of the P3 standard.
- Shows 70% of the NTSC standard colors.
- Shows 74% of the colors of the Adobe RGB standard.
Contrast Between Monitors
The differences in contrast between monitors.
Monitor TN
- The TN monitor has greater contrast in dark windows, but the black quality is not as intense.
Monitor VA
- The VA panel monitor presents even greater contrast in dark windows, with deeper blacks.
Monitor IPS
- The IPS monitor also has good contrast, but the blacks may be less intense compared to the VA monitor.
Response Time and Motion Blur
Monitor response time and its impact on motion blur.
- Response time is the time it takes for each pixel to change color.
- The GTG (gray to gray) scale is used to measure response time.
- The shorter the GTG response time, the less motion blur there will be.
- In addition to the GTG scale, there is the MPRT (motion picture response time) scale, which measures motion blur in moving images.
- It is important to check that the information provided by the manufacturer about the MPRT scale is accurate before making a decision about which monitor to choose.
Considerations
- Monitor specifications are more advanced today, taking into account factors such as refresh rate and response time.
- There are significant differences in color reproduction and contrast between different panel types (TN, VA and IPS).
- Response time and motion blur are important factors to consider when choosing a monitor.
- It is essential to obtain accurate information about the GTG and MPRT scales provided by manufacturers before making a decision.
