LG 27GX790A-B stuck at 10 Gbps/lane with RTX 5060 Ti - should it be 13.5?
Posted: 03 Sep 2026, 15:09
I’m having a weird issue with my LG 27GX790A-B and RTX 5060 Ti and wanted to see if anyone here has run into the same thing.
GPU-Z is showing:
Current Link Rate: 10.0 Gbps
Max Link Rate: 10.0 Gbps
Lane Count: 4
So it looks like the monitor is only running at UHBR10 / 40 Gbps instead of UHBR13.5 / 54 Gbps.
I’m running 2560x1440 at 480 Hz, 8-bit RGB. G-SYNC is off, Windows HDR is off, and DAS is on.
Right now I’m using a 6.6 ft IVANKY DP80 cable that is supposedly VESA certified:

I also ordered a shorter 3.3 ft Silkland DP80 cable that should arrive later today:

I’ve updated to the latest NVIDIA driver, checked MSI’s support page and don’t see any VBIOS/firmware update for the card, and the GPU otherwise seems to be working normally.
I also ordered the USB-A to USB-B cable for the monitor so I can check LG Switch for any monitor firmware updates.
Is this a known issue with this monitor and RTX 50-series cards, or does it sound like something specific to my setup?
If anyone has this monitor with a 50-series GPU, what link rate does GPU-Z show for you? And if you were stuck at 10.0 Gbps, was there anything that fixed it?
I'm hoping to run the monitor without needing DSC.
