Unable to achieve 1440p at 360Hz on your ASUS ROG Strix OLED XG27ACDNG.
Unable to achieve 1440p at 360Hz on your ASUS ROG Strix OLED XG27ACDNG.
Hi there, I recently purchased this monitor but still can’t get the 1440p 360Hz to function properly. It only lets me reach up to 180Hz in NVIDIA Control Panel and Windows Advanced Settings. There’s an option to switch to 1080p 360Hz, though. I’ve confirmed DSC is enabled in the monitor’s settings and attempted a reset via there. I’m probably making a mistake, but I’m stuck on what’s wrong. For more details, I’m using an ASUS RTX 1060, which should support higher refresh rates based on online reviews. I’ve tried both DisplayPort and HDMI—DisplayPort supports up to 180Hz while HDMI only offers a max of 144Hz. The monitor was sold as a demo and returned by the previous buyer. They claim it’s tested and working correctly. Am I overreacting, or did I buy a faulty unit? Please help me understand. Thanks in advance, Mikkel
Based on the information available, you'll likely need a GTX 16-series or RTX 20-series card for DSC over DP and a 30-series card for DSC over HDMI. The GTX 1060 doesn't meet these requirements. It supports only DP 1.4a (up to 25.92 Gbps) and HDMI 2.0 (up to 14.4 Gbps). Without HBR3 support, achieving higher refresh rates would be challenging.
Sure thing! Basically, you're asking if upgrading your PC will solve the problem you're facing. You tried using a monitor from before and checked with an older setup (1060), and AI suggested it should work in DP 1.4a. However, you think the AI might have been wrong about 1080p. Thanks for sharing the details!
Just a quick note, AI summaries can help with some topics but they’re usually unreliable for detailed computer hardware details. They often pull incorrect information from various sources. If you want accurate specs, it’s best to check the official documentation or trusted sites. This should apply to other areas like cars or tools too—AI tends to mix up details a lot.
It's achievable via DP 1.4a using DSC, though your card doesn't appear to back it up. Both the GPU and monitor must be compatible. The card compresses data, while the monitor decompresses it again. Uncompressed 1440p at 360 Hz demands 39.37 Gbps. DSC lowers the bandwidth needs, allowing use with ports and cables that support lower rates. Still, it must work on both ends of the connection.
Sure, glad to hear that! As long as everything functions smoothly after the new PC arrives, I’m all set. I wasn’t expecting it to be compatible right away—hoping the setup feels good. I thought the machine might be outdated, but the details were a bit unclear, which is understandable since I’m not always the most tech-savvy. Thanks again for the helpful advice; your insights really make a difference!
Absolutely, that's correct. During the planning phase, I realized it wasn't worth relying on hardware specs without more details. I didn’t want to commit to something I couldn’t properly investigate, so I asked about compatibility with a 1060 and got a clear response. I usually stay cautious with AI, but in this case, @Eigenvektor gave me the right information.
