Another spec that is worth paying attention to is response time. Also measured in milliseconds, it refers to how fast pixels on the display switch from one color to another. Faster response times result in better viewing experiences during fast-paced scenes, while slower response times can result in ghosting or blurring of the image.
Response time relates closely to the type of panel technology used in displays: twisted nematic (TN), vertical alignment (VA), and in-plane switching (IPS). While you do not need to understand their technical differences, it is worth mentioning their pros and cons for gamers. TN panels tend to have the best response times while trading off picture quality. IPS panels are the opposite with great colors and viewing angles but slower response. VA panels offer the best of both worlds with good response times and color reproduction.
Overall, modern TVs have much higher response times than monitors, which might result in ghosting and worse picture quality. Casual gamers are happy with a response time of about 10 milliseconds, while competitive and professional gamers usually target something closer to 1 millisecond. Be sure to checkout the BenQ
Additionally, Xbox One supports a feature usually reserved for PC gaming called variable refresh rate. This technology, commonly found in the form of AMD FreeSync (or NVIDIA’s proprietary G-Sync), allows the video source and monitor to communicate and dynamically match the FPS of the source to the refresh rate of the display for smooth and tear-free gaming.
Gaming monitors like the BenQ EX2780Q support AMD FreeSync and a 144Hz refresh rate for smooth gaming free of screen tearing.
Most of modern televisions and monitors feature 4K resolution, meaning that they can provide sharper and more detailed images of 3840 X 2160 pixels. TVs are designed to be viewed from a far, with a lower pixel density. Thus, when viewed from a short distance, the image turns out pixelated. Gamers who use a display at a shorter distance to have a more immersive gaming experience, might want to pick out monitors with a higher pixel density. No one would like to play games watching images with low pixel density.
Last but not the least, a display which can offer you viewing comfort is also a feature you need to take into consideration as well. Low blue light and flicker-free are just the basic; a monitor with brightness intelligence which can be adapted to the ambient light will offer the gaming experience.
