I just got an Asus ROG Strix XG27ACDNG OLED monitor and I'm having trouble getting the refresh rate above 180Hz. My PC is a bit dated, equipped with a 3GB GTX 1060 running Windows 10, but I thought I should still be able to hit 360Hz. The advanced display settings only show a max of 60Hz, even though it feels like it's running higher. In the NVIDIA control panel, it's stuck at 180Hz. I've made sure I'm using the DisplayPort cable that came with the monitor and it's connected to the GPU, not the motherboard. I also confirmed that DSC is enabled, Display Streaming is set to 1.4, VRR is on, and G-Sync is activated in the NVIDIA panel. However, when I switch to 1080p resolution, I can select 240Hz and 360Hz, but not at the native 1440p resolution. Is my aging GPU holding me back?

Your GPU supports DisplayPort 1.4a, which unfortunately can't handle 240Hz at 10-bit color in 1440p. Are you considering a new GPU? That would definitely help.
Honestly, it's kind of surprising you got a new monitor without upgrading your GPU. The GTX 1060 can only manage up to 240Hz at lower resolutions, so you're definitely going to hit some limits there with 1440p. Might be time to think about a full system upgrade!
For OLED displays, I would recommend using HDMI since it can handle more bandwidth, especially for higher refresh rates. However, DisplayPort is also solid for high-res and fast video. Just be sure you're using the correct cable!
Actually, I’ve read that DisplayPort is designed for higher resolutions and refresh rates. I’m building a new PC soon, but I didn’t want to wait for half the parts to arrive. Just trying to troubleshoot any issues ahead of time. I know my current rig won’t consistently hit 360Hz in games, but I thought I could still see it as an option.
