My dream computer monitor that can be possible next year (2018)

[GrindyGamer]

According to Wikipedia. vesa is working on an improvement of  their diaplayport 1.4  so it can handle 40 Gbit/s bandwidth that can come as early as Q1 2018 . (https://en.wikipedia.org/wiki/DisplayPort#1.4) so what do i want with this bandwidth .

34 inch , 21:9 , 5120 X 2160 , 120 hz , 8 bit (10 bit with FRC) , HDR . (comes at 39.81 Gbit/s )

This comes just below the bandwidth. check this calculator: https://k.kramerav.com/support/bwcalculator.asp.

This give you ultrawide at the 4k resolution level of PPI and the 120 hz refresh rate . all these specs at the point of  severe diminishing returns so it is perfect to get most bang out of the bandwidth.

Make sure to use the tool above and tell me how you want the bandwidth to be utilized.

this an ad for that tool or something?

sigh. even if i was associated with this website which i am not. do you see any ads on it. so what would i gain. just found it and it makes my life easier rather than doing the calculations manually so i thought i would share geez.

Bandwidth is not all available to be used for data bits, as some bits of the bandwidth are used for encoding purposes to keep the transmission in sync and operating properly.  What you need to look at is the data rate, which is the amount of data that can be sent over the connection, which is only a portion of the bandwidth.

 

DisplayPort 1.2 for example has 21.6 Gbit/s bandwidth, but only 17.28 Gbit/s (80%) of that is used for representing data. If DP continues using the same encoding scheme then 40 Gbit/s bandwidth will give 32 Gbit/s data rate.

 

The Wikipedia page does note this in the same paragraph:

Quote

According to a roadmap published by VESA in September 2016, a new version of DisplayPort should be launched in 2017. It improves the link rate from 8.1 to 10 Gbit/s, a 24% increase.[25][26] This will increase the total bandwidth from 32.4 Gbit/s to 40.0 Gbit/s. It is unclear whether or not the new version will continue using the 8b/10b scheme for transport encoding like previous versions, but if so, the maximum data rate for video will be 32.0 Gbit/s.

 

You can also just use this for data rate calculations

EDIT: It does look like the calculator you used does include encoding overhead, though it still does not account for other things like blanking intervals which increase the bandwidth requirements.

 

But anyway, I'm not much of an ultrawide guy so personally I'd like to see a 4096×2560 (16:10) 10 bpc monitor

thanks for the reply. even if there is not enough bandwidth i will go for 100-110 hz instead of 120 hz . no bigge
