LG shows IPS monitors with response speed of 1ms
LG has shown two new IPS monitors for gamers during the E3 game fair in Los Angeles. It concerns a 27″ and 38″ copy, both of which have high refresh rates and, according to LG, achieve a response speed of 1ms.
LG reports that the specified response speed of 1ms refers to the gray-to-gray response time. According to the manufacturer, this applies to both the 38GL950G and the smaller 27GL850. With such responsiveness, these panels can compete on paper in response speed with monitors equipped with tn panels.
In addition to 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. In terms of refresh rate, there’s also a difference: the smaller of the two doesn’t go beyond 144Hz, while the larger one from 144Hz can be overclocked to 175Hz.
Furthermore, there is a difference in adjusting the refresh rate to the output of the GPU of a connected computer. The 38GL950G supports Nvidia’s G-Sync, 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 label G-Sync Compatible, Nvidia guarantees that the screen can also adapt to the output of Geforce GPUs without there is flickering or artifacts LG does not mention within which 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 this range due to its value of 350cd/m². This 27″ monitor does support HDR10, but in view of the lack of a DisplayHDR label, it will not be able to generate a convincing HDR experience. Incidentally, DisplayHDR 400 is the lowest category that VESA assigns to HDR monitors. 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.
