Anyone else figure this out? The monitors are working well but i can't get the HiDPI resolutions i want. Basically the only options presented that are at full 5K are 5120x2160 (which is 1:1 and everything is too small on the monitor for practical everyday use) or 2560x1080, which puts the monitors into 5120x2160 full rez mode but doubles the scaling on everything. This looks good, but everything is too large (scaled up) for my taste- i dont want such a small "looks like" resolution.
The sweet spot for these monitors is a HiDPI scaled 3440x1440 resolution, where the image is processed at some 6K+ (i think 6880 x 2880 is the resolution it renders the desktop at) and then downscales to 5120x2160 and scaled as though it was 3440x1440. I dont understand why the full HiDPI modes (and even the typical HiDPI scaled menu in system preferences->Displays) is missing. If i plug my real MacBook pro into the monitor i get the proper resolution options i am after (with the typical HiDPI scaled menu options for "more space" or "larger text". But on my hackintosh i don't get these options. i have tried with a 1080ti in 10.13.6, then a Vega64 in mojave and now using a radeon vii in 10.14.5 and the issue persists regardless of the setup.
Thanks,
