Despite the GeForce RTX 4090 is the most modern and powerful card on the market for gamers, it does not have all the latest technologies. In fact, for example, NVIDIA has decided to stay on the “older” standard DisplayPort 1.4a instead of upgrading to the latest 2.0, limiting the video output to a maximum resolution of 4K at 120Hzor 8K at 60Hz. Although these are decidedly high resolutions and frame rates and barely achievable with triple A titles at the highest level of detail (although certainly not impossible), the fact remains that the integration of DisplayPort 2.0 ports would have been very welcome.
Recall that the DisplayPort 2.0 standard allows you to reach incredibly high resolutions and refresh rates, such as 10K at 60Hz, 8K at 120Hz or 4K at 240Hz without any color compression, thanks to three times the data transfer rate (from 25.92 to 77.37 Gb / s). For comparison, DisplayPort 1.4a maxes out at 4K 144Hz with Display Stream Compression on.
The GeForce RTX 4090 is a very powerful card that can already generate over 120fps on eSports titles at 4K resolution, so the DisplayPort 1.4a limits this possibility. Obviously, we also need monitors capable of making the most of the Display Port 2.0 connection and, currently, they are not yet present on the market. In fact, 4K monitors rely on Display Stream Compression or connecting multiple Display Port cables to achieve refresh rates above 120Hz.
It will be necessary to wait several months before seeing monitors equipped with DisplayPort 2.0 connectors in circulation and, most likely, NVIDIA will have taken this factor into consideration to choose to keep DisplayPort 1.4a also on its brand new flagship of the Ada Lovelace family. According to the latest information released on the net, it seems that AMD has instead chosen to use DisplayPort 2.0 ports on its next series of cards. Radeon RX 7000 based onRDNA architecture 3.
