The Consumer Electronics Show (CES) has usually been a hub for unveiling of new television technology, usually led by South Korean manufacturers LG and Samsung. This year, LG announced that some of its new televisions will support Nvidia’s G-Sync technology for improved gaming on televisions.
“As the first TV manufacturer to offer NVIDIA G-SYNC® Compatibility, LG is expanding this capability in 2020 to 12 OLED (Optical Light Emitting Diode) TVs to provide a flawless PC gaming experience without screen tearing or other distracting visual artifacts," the company said.
This means the television will support variable refresh rates of up to 120Hz at 4K resolution for gamers. Refresh rate is the number of images a screen can display in a second. Since video is nothing more than “moving pictures", higher refresh rates allow smoother and more natural video playback.
The 12 new Nvidia G-Sync capable TVs in LG’s lineup range from 48-inch to 88-inch screen sizes. According to reports, Advanced Micro Devices’ (AMD) FreeSync software is also supported.
G-Sync and FreeSync are the same technologies but from different manufacturers. Both avoid screen tearing while gaming, which is a result of a graphics card (CPU) outputting higher frame rates than a screen is capable of displaying. The technologies match the refresh rates so that screen tearing can be avoided.
Screen tearing is an effect where the GPU starts showing the next frame before the current one is over. It’s often visible in games, where part of an object seems to overlap itself or pull away from the rest of the body.
Traditionally, G-Sync and FreeSync have been possible on computer monitors only, that too when connected with compatible graphics cards. But by allowing it on TVs, LG is presumably preparing for the next generation of consoles. Both the Xbox Series X from Microsoft and Sony’s PlayStation 5 are expected to have GPUs compatible with these technologies.
Alternatively, if your TV supports such technology, it makes it more feasible to connect a gaming PC to the television for visual output. By allowing such technology on TVs, LG is effectively reducing the gap between gaming monitors and regular televisions, hopefully eliminating the need to choose between a TV or monitor when gamers are choosing components for their machines.
