The new monitor doesn't just feature high pixel density; it also comes at a "high" cost, for which one could easily afford a good 4K OLED monitor.
ASUS Debuts ROG Strix XG27JCG, Boasting 5K@180Hz and 2K@330Hz Modes on a Fast IPS Panel
ASUS recently launched its flagship IPS gaming monitor, called ROG Strix XG27JCG, which is the world's first 5K@180Hz monitor. It's common to see 4K IPS panels with high refresh rates, but 5K resolution increases the pixel density incredibly to offer more vivid visuals. On paper, 4K to 5K resolution may look smaller, but you are getting a whopping 77% more pixels on a 5K panel, which should explain why it's impressive to see a 5K@180Hz display.
Nonetheless, it's in the enthusiast-grade segment and will cost a lot compared to conventional 4K IPS monitors. As per the specs, the ROG Strix XG27JCG brings an incredible 218 ppi (pixels per inch) using a 27-inch screen, and with a refresh rate of 180 Hz, it's ready for competitive/smooth gaming. Looks like ASUS has used an even advanced Fast IPS panel on this one, as we are seeing a very low 0.3 ms of GtG response time, which typically is around 1 ms on most Fast IPS monitors.
The monitor boasts a dual-mode configuration, offering either 5K@180Hz mode or the QHD@330Hz. So, users will have the choice to choose between high-fidelity and fluid gameplay. However, sustaining 180 FPS at 5K resolution is an exceptionally tough challenge for any GPU. It's going to be even difficult for the GeForce RTX 5090, considering modern Triple-A titles have become a lot more intensive. That said, the QHD@330Hz mode looks more ideal for most gamers and offers more fluidity.
ASUS has ensured the gameplay doesn't annoy users with screen-tearing and has equipped it with AMD FreeSync Premium technology as well as NVIDIA G-Sync compatibility. The contrast is also good compared to regular IPS panels, and we are seeing a 1500:1 ratio on this one. Color reproduction is also impressive, including 97% DCI-P3 color coverage and a color accuracy of Delta E < 2. The monitor supports HDR as well and can achieve 600 Nits Peak brightness in HDR mode.
Support for 5K resolution at up to 180Hz requires a compatible graphics card. Only NVIDIA GeForce 50-series GPUs and AMD Radeon RX 7600 or newer meet this requirement. Actual compatibility, performance, and feature availability may vary depending on system hardware, drivers, and software environment...

Moving to the connectivity, here we see it equipped with 2x HDMI 2.1 ports, a DP 1.4 port, and a USB-C (Alt DP) for display output. Unfortunately, we aren't seeing a DP 2.1 on this one, which is really required to have uncompressed visuals at 5K@180Hz mode. As spotted by Videocardz, ASUS doesn't recommend the GeForce RTX 40 series for the same, and only recommends either the RTX 50 series or AMD RX 7600 or higher AMD GPUs. Despite having an older DP interface, it still says that older GPUs than these are "not" compatible. So, quite weird.
It's disappointing to see the same old DP 1.4 on high-end monitors like these, particularly when you are paying a whopping $850 for this model, according to the Hong Kong retail listings. At this price, you can get the MSI MAG 321CUP QD-OLED panel that boasts a good 4K resolution with a 165 Hz refresh rate, offering far superior contrast and visual quality.
