AU Optronics and LG Display are already working on LCD panels with a refresh rate of 480Hz, according to reports from TFT Central. According to these, LG Display works on several models of panels, the first being with a diagonal of 24.5 inches and 1080p resolution And with a launch projection for 2022, so if all goes well, we’ll see the first 480Hz gaming monitors on the market at the end of next year.
The first 480 Hz LCD screens will only be Full HD
AU Optronics, meanwhile, is also developing a 1080p and 480Hz resolution panel, but in this case, they only said they intended to start serial production in 2022, without stating a quarter or any additional information. , so we can only elucidate what will happen with it (although it is true that the launch timing is most likely quite similar to LG’s).
At the moment, there isn’t much more information available, which isn’t particularly surprising given that the launch is still a long way off. Current 360Hz displays use an LED-TN panel, although it is true that the new AU Optronics 390Hz panels have switched to the AHVA panel type (IPS type), but we don’t know what panel type the newer monitors have. will use. Hz neither from LG nor from AU Optronics.
To be able to drive a panel with such a wide variable refresh rate range (30 to 480 Hz), you will need extremely powerful display driver logic. This chipset (or maybe just a very powerful one) will need to include very high performance image processing capability, a suitable overdrive processor, a very fast TCON (time controller) and a general purpose processor that will handle the operation of these units. In short, these monitors will have very powerful and advanced technology that will make their selling price quite expensive.
Too many refresh rates for current GPUs?
Regardless of our screen refresh rate, it is of little use if the graphics card is unable to match FPS with this value, even if you have variable refresh rate technology. such as FreeSync or G-Sync. Having said that, even if you have a 480Hz monitor if your graphics card is not capable of 480 FPS in games, in reality you are not only wasting the potential of the monitor but you could also experience stuttering and tearing issues if the technological variable refreshes rate does not work as it should.
For today’s 360Hz monitors, a high-end GPU is required and many times you just have to relax the graphics settings to be able to achieve those frame-per-second levels that allow for a smooth gaming experience, not to mention that At the moment they will only be available in 1080p resolution and ultra high resolution is not even taken into account.
Therefore, personally, it seems to us too early to launch 480 Hz monitors when current GPUs already have problems handling 360 Hz. It is true that the launch of these monitors might not take place for at least two years and by then we will have the new GPU generations from AMD and NVIDIA, but we still don’t have a lot of information on that and we don’t know what can happen.
