You may have connected it the wrong way round, as I did. With this cable it really depends :)
Odyssey G7 works 240 Hz and 1ms, this is not a problem for DP 1.4 and 2m.
No, unfortunately anything higher than 85Hz did not work for me. The screen remained black in each case. I think the cable meets the DP 1.1 specifications with 10.8Gbps. This one, on the other hand, worked: Lindy DP-DP M-M (7.50m, Midrange)
Unfortunately, the cable only supports 60hz at 4k.
According to the manufacturer, 4k/60hz is only supported up to 3 metres. I am not currently aware of any cable that transmits 4k/60hz over 20 metres, so you will probably need a repeater for such a length.
So these 3m DisplayPort cables have DisplayPort version 1.4, so they support 1440p at 240Hz. With your 1.5m cables, of course, I can't tell which version they have. The length makes no difference here (at least under 10 metres), it depends on the bandwidth or the DisplayPort version.
