The specification sheet of the the CSV-1460 mentions single screen setup 5120 × 2880 @60 Hz.
Does it also support single screen setup 5120 × 2160 @60 Hz?
They are less pixels so I would say yes it should support it.
CSV-1460: single screen setup 5120 × 2160 @60 Hz supported?
Maybe not. The CSV-1460 uses DisplayLink which is limited to HBR2 link rate.
I think 5120x2880 refers to dual cable 5K displays where each 2560x2880 half of the display uses a separate DisplayPort 1.2 HBR2 x4 connection.
5120x2160 displays don't have a dual cable mode unless it's through a Thunderbolt port (where the Thunderbolt port carries two DisplayPort HBR2 x4 connections - one for each 2560x2160 half of the display). Exactly which display do you have?
5120x2160 60Hz only requires 693 MHz pixel clock which should be doable with HBR2 x4 at 8bpc but I don't think DisplayLink supports widths greater than 4K. Actually, https://support.displaylink.com/knowledgebase/articles/525038-displaylink-display-resolution-support says DisplayLink can do 5120x1440 60Hz. Maybe it can do 5120x2160 60Hz then (if it allows 8bpc)?
I guess first you should determine if the display will do 5120x2160 using HBR2 link rate from a normal GPU.
