Samsung lately launched its new Odyssey Neo G9 show. It’s a high-resolution show: 7680 x 2160, i.e. double UHD, all at 240 Hz. However, when you have an NVIDIA RTX 40, you received’t have the ability to take pleasure in this decision at this frequency. For this, an AMD RX 7000 is required.
Odyssey Neo G9 RTX 40 – not a superb match!
At current, there are not any 36 options if you wish to take pleasure in your Samsung 240 Hz show in its native decision. Indeed, in accordance with assessments by our South Korean colleagues Quasarzone, solely AMD’s RX 7000 are able to operating on this display. Unfortunately, neither the Intel Arc nor the RTX 40 are in a position to run at 7680 x 2160 @240 Hz.
Indeed, on this decision, even an RTX 4090 was unable to show a clean picture. To obtain this, the show frequency needed to be lowered to 120 Hz, regardless of the usage of HDMI 2.1. Although HDMI 2.1 supplies the required bandwidth for this configuration, it appears that evidently the issue goes deeper than that.
Apparently, in accordance with a redditor, the issue stems from an issue with DSC, a picture compression system, and the variety of RTX 40 pipelines. Without compression, such a decision at this frequency would require a bandwidth of 109.68 Gbit/s, whereas DisplayPort 2.1 permits a bp of 77.37 Gbit/s, in contrast with 48 Gbit/s for HDMI 2.1. So when the RTX 4090 tries to show 7680×2160@240 Hz, a compression bottleneck happens, and it doesn’t work properly.
Of course, that is the shortened turbo model, however Tom’s Hardware explains the issue in additional element.
In absolute phrases, you may say it’s an issue with out being an issue, since de facto, it’s unlikely to play at 7680 x 2160 at 240 fps… But it’s nonetheless a disgrace not to have the ability to take pleasure in your display within the situations it was designed for.
