Something is was looking forward to for a while to utilize the full potential of my monitor even with devices that does not have a Displayport connection.
Check out the CAC-1331

HDMI TO DISPLAYPORT
https://twitter.com/pinkiesales_ is also selling their version of this for $100. I got mine months ago and it's still working fine I'm able to play on my Xbox one x at 4k 60hz through my up3218k monitor
I have tried the CAC-1331 with my Acer XV273K display and Radeon RX 580 (using CAC-2068 cable).
The CAC-1331 can do 4096x2304 but some timings cause a problem. For example, the native timing of the 21.5" LG UltraFine 4K display does not work through the CAC-1331 even though the XV273K can accept the timing from HDMI 2.0 or DisplayPort.
[email protected] 142.198kHz 593.82MHz h(8 32 40 +) v(1 8 57 -) 16:9
Some CVT-RB timings for 4096x2304 do work (50Hz, 51Hz, 53Hz, 57Hz, 58Hz) but some do not (52Hz, 54Hz, etc.)
Some timings have the wrong colors (3840x2160 594MHz has wrong colors but 3840x2160 at 533MHz is good).
I could not get any 5120x1440, 5120x2160, or 5120x2880 timings to work even with refresh rate set as low as 30Hz.
Kind of disappointing. I would expect any timing to work as long as the pixel clock is 600 MHz or less (the limit of HDMI 2.0 at 8 bpc and no chroma sub sampling). It would be cool if it could support higher pixel clock with chroma sub sampling (for example, 4:2:0 can do 1200 MHz with 8 bpc; DisplayPort 1.2 is limited to 4:2:2 which can do 1080 MHz at 8 bpc - good enough for 5K 60Hz).
