NVIDIA launches new technology to support graphics cards GeForce and the monitors G-Sync.
At the Computex in Taipei, NVIDIA had no new GPUs to highlight. The company has therefore bet on new technologies to make people talk about it.
ULMB back after 8 years
It was thus a question of evoking the ULMB2 which logically follows on from the ULMB1 presented in 2015 (an eternity ago, therefore), but which had had difficulty in convincing, due to constraints deemed prohibitive.
At the time, it was necessary in particular to do with a sharp drop in the brightness and the refresh rate of the screen to take advantage of this Ultra Low Motion Blur. As its name suggests, it must allow a very strong reduction of what is called motion blur, in other words the loss of sharpness linked to the movement of the camera and objects in the image.
Logically, the ULMB2 returns to the flaws of the 2015 technology while confirming its strengths. NVIDIA states that ” compared to the original, the ULMB2 offers a full backlight refresh rate, almost twice the brightness and virtually zero crosstalk “.
An “equivalent” to 1440 Hz?
In principle, the ULMB is a technology that aims to reduce all that is blurry surrounding the movement. In fact, we must end up with something clearer for more visual comfort. NVIDIA clarifies that to achieve this, “ the ULMB deactivates the backlight 75% of the time. That 25% duty cycle on a 300-nit max panel meant images would be clear, but less bright. »
The ULMB2 benefits from the progress made on monitor panels, but also from the integration of G-Sync, and is capable of ” provide this backlight strobing at the monitor’s optimal refresh rate “. The result is much brighter rendering and superior image quality. The idea is also to be able to adjust the response time of the pixels, so that the color change of the pixel does not occur at the moment when it must be turned off to preserve sharpness.
NVIDIA is obviously full of praise for its new technology, and it had fun talking about a motion clarity equivalent to that of a hypothetical 1440 Hz panel with a 360 Hz ULMB2 monitor. It will of course be necessary to check the rendering in practice. Note that the ULMB2 will be available through a firmware update for two monitors (Acer Predator XB273U F and ASUS ROG Swift PG27AQN). Others should follow…
