The RTX 4090 GPU from NVIDIA, known for its premium price tag, has earned a reputation for unparalleled performance, securing its place as the ultimate “halo card” for many enthusiasts.
On the other side Odyssey Neo G9, with its colossal 57-inch curved display, had garnered substantial excitement within the gaming community for its extraordinary capabilities. Supporting an ultrawide resolution of 7680×2160, the monitor promised an unparalleled gaming experience. However, recent tests have demonstrated that the GeForce RTX 4090 falls short of delivering on this potential.
Reviews conducted by QuasarZone, a reputable source for gaming hardware evaluations, shed light on this unexpected limitation. It was discovered that, regardless of whether a DisplayPort 2.1 or HDMI 2.1 connection was employed, the GeForce RTX 4090 struggled to unlock the Neo G9’s full potential. Instead of the anticipated 240Hz refresh rate, the monitor was capped at 120Hz, presenting a significant discrepancy from its advertised specifications.
This revelation has left gamers and tech enthusiasts puzzled, as the GeForce RTX 4090 is widely regarded as one of the most powerful graphics cards on the market. Its impressive specs, including massive VRAM and exceptional computational capabilities, had positioned it as an ideal companion for cutting-edge gaming hardware, such as the Odyssey Neo G9.
One plausible explanation for this limitation may lie in the intricacies of data transmission. Another explanation is also provided by Reddit user.

Samsung’s Neo G9, essentially comprising two 4K 240Hz displays amalgamated into one, demands an extensive bandwidth to function optimally. Transmitting uncompressed video at this resolution and refresh rate necessitates a staggering 109.68 gigabits per second (Gbit/s) of bandwidth. Presently, the highest available bandwidth through a single display connection is 77.37 Gbit/s using DisplayPort 2.1 or 48 Gbit/s via HDMI 2.1. This discrepancy calls for the utilization of Display Stream Compression (DSC) technology.
DSC enables the compression of images to 8 bits per pixel (bpp) without any discernible loss in quality. For the Neo G9, with DSC enabled, a theoretical bandwidth requirement of 36.56 Gbit/s is projected—well within the capabilities of HDMI 2.1. However, complications may arise in the form of fixed-size segments or slices in the uncompressed video frame, as well as potential optimization issues within certain hardware or software implementations.
The exact reasons behind the GeForce RTX 4090’s limitation remain speculative. It remains to be seen whether this issue can be addressed through software or firmware updates. In the meantime, it appears that the Odyssey Neo G9’s optimal performance can only be realized with AMD’s Radeon RX 7000-series graphics cards, which have been shown to handle the display’s demanding specifications without issue.
This unexpected development serves as a reminder of the complexities that can arise when pushing the boundaries of gaming hardware, and underscores the importance of comprehensive testing and evaluation in the pursuit of the ultimate gaming experience.
