LG shows IPS monitors with a response speed of 1ms

LG showed off two new IPS monitors for gamers at the E3 game fair in Los Angeles. It concerns a 27″ and 38″ model that both have high refresh rates and, according to LG, achieve a response speed of 1ms.

LG reports that the stated response speed of 1ms is the gray-to-gray response time. According to the manufacturer, this applies to both the 38GL950G and the smaller 27GL850. With such a responsiveness, these panels can compete on paper with monitors equipped with tn panels in terms of responsiveness.

Besides the difference in screen diagonal, the 27GL850 has a resolution of 2560×1440 pixels and therefore an aspect ratio of 16:9, while the 38GL950G has a 21:9 screen with a resolution of 3840×1600 pixels. The 27″ monitor achieves a maximum brightness of 350cd/m², while the larger 38″ screen achieves 450cd/m². There’s also a difference on the refresh rate front: the smaller of the two doesn’t go beyond 144Hz, while the larger one can be overclocked from 144Hz to 175Hz.

There is also a difference when it comes to adjusting the refresh rate on the output of the gpu of a connected computer. The 38GL950G supports G-Sync from Nvidia, while the 27GL850 has G-Sync Compatible status. The latter means that the 27″ monitor supports adaptive sync from VESA, which is also known as AMD’s FreeSync. With the G-Sync Compatible label, Nvidia guarantees that the screen can also adapt to the output of Geforce GPUs, without any interference. there is flickering or artifacts LG does not mention within what range the monitors can adjust their refresh rates to the frame rate that the gpu of a connected computer squeezes out.

The mentioned difference in maximum brightness has consequences for the assignment of a DisplayHDR label by VESA. The standardization organization has, among other things, created the DisplayHDR 400 label for monitors that can produce a certain minimum level of HDR. For this, the maximum peak brightness must be at least 400cd/m². The 27GL850 falls outside because of its value of 350cd/m². This 27″ monitor does support HDR10, but given the lack of a DisplayHDR label, will not be able to generate a convincing HDR experience. Incidentally, DisplayHDR 400 is the lowest category that VESA assigns to HDR monitors. Both LG screens can Display 98 percent of the dci-p3 color space.

Both monitors will be available from July. In the United States, the 27GL850 will be available for pre-order starting July 1. LG says that this screen is “expected to be for sale in a limited edition in the Benelux” in the course of July. The 38GL950G will come to the Benelux in the third quarter of this year. Prices have not yet been announced.
