The most common thing about the LCD monitors of old was the fact that they didn't have a great idea of movement in gaming, something CRTs did.
For those of a certain age and in the computer world over the past 20 years, CRT monitors have been able to unanimously adjust the refresh rate of each panel with the displayed solution without creating a blurry LCD even afterwards. OLED everything has changed.
Black Steel Fittings: a widely used technology to reduce invisibility
This technology, also known as BFI, has come naturally from different manufacturers, where each has called it a different and surprisingly, to take different but different approaches.
BFI is often confused or called backlight strobing, but unlike the first one it supports a single called PWM Flicker. Black Frame Installation Thus a technology with the same purpose as the so-called rear mounting lamps, that is, minimizes motion blurring through the dark period or the time between refresh view.
Logically, then, the term BFI, which attempts to be as synchronous to the light phases as the old CRTs do.
How and when does BFI work?
BFI incorporates a completely black frame between the monitor and the next frame refresh, indicating that the refresh rate is double, even though the same FPS is used for the rest of the GPU.
For a practical example, a 60 Hz monitor with BFI is capable of reproducing 120 Hz due to the darker layer they accumulate at each screen refresh. As we say, the monitor continues to refresh 60 times per second, but when it includes a black frame, the user's feeling is similar that the average of those same hertz doubles depends on the smooth.
The problem is that there are many products that this effect does not perform well, that is, managers integrate enough speed in the panel so that the BFI effect is more favorable than the problem.
If black frame (also called Dark Frames by many) does not change the situation before the level of the kiss begins, what is produced is a poorly crafted texture in the sculpture rather than a smooth feeling. In addition, the BFI sensation improves or worsens on the Hertz level of our monitor, unlike 24 Hz, and 25 Hz, like 120 Hz.
There are frequencies that are ready for this technology and with a few hertz variations you can see improvement, or on the other hand, an increase in image smoothness. This is especially the case with most TVs, which try to offer a very smooth X X rate for hertz, but instead the loss of smoothness causes the user to decide disable BFI technology the owner of your television.
