So, I'm going to answer the OP more directly, and hopefully this will be a 'nice reference'
for everyone ...

Again, here in the US, LG offers a G-sync

That said ...

The RTX2070 supports ...

DVI-D Dual-Link (DL)Which brings me to this 'super-list' of standards ... SIDE NOTE: I'm purposely leaving out the 64/66b or 8/10b 'encoding' discussions on Gbps/MHz, as well as TDMS and other 'signaling' limitations (long story, affects 'usable' throughput).

7.92 Gbps -- 1920x1080@144Hz, 1920x1200@120Hz, 2560x1200@60HzDVI-D DL was used for the early 120-150Hz 3D (60-75Hz each eye) lenticular filtered panels for 3D Shutter Glasses, often which could do 120 and 144Hz without glasses as well

You must have:
Graphics card with capable port
Monitor with capable port and standard-support
Spec cable required to push bandwidthSIDE NOTE: On notebooks that have an integrated Intel GPU, the discrete GPU still uses the RAMDAC or eDP of the integrated Intel GPU, and is as the mercy of its limitations. E.g., 500 series Intel GPUs are limited to 2.5K@60Hz, and it requires a 600 series to use 4K@60Hz, even if the discrete nVidia GPU is more than capable.

The OP message was from 2019 March, but now that the RTX 2070 Super is here, that's probably the best buy out there -- price-performance, unless one can tolerate a RTX 2060 series or lower, of course.
