I suspect the answer is no, but:
Does anyone know if any Intel integrated graphics can drive a DisplayPort 1.2 single stream (SST) monitor at 4096 x 2160, 60 Hz, 10 bits/channel (30-bit colour)? I'm asking as I have a 30-bit monitor of that res. on its way (LG 31MU97Z).
What I have found so far:
Anyone with way more knowledge on this than me who can weigh in?
Does anyone know if any Intel integrated graphics can drive a DisplayPort 1.2 single stream (SST) monitor at 4096 x 2160, 60 Hz, 10 bits/channel (30-bit colour)? I'm asking as I have a 30-bit monitor of that res. on its way (LG 31MU97Z).
What I have found so far:
- DisplayPort 1.2 supports CVT-R so I'm calculating data below based on those timings, and VESA's downloadable timing calculator spreadsheet.
- The limiting factor seems to be CDCLK (pixel clock) of the GPU
- Haswell is either 540 MHz (can do UHD @ 60 Hz/24-bit) or 450 MHz (maxes out at ~ 50 Hz) depending on TDP
- Broadwell supports 4096 x 2304 @ 60 Hz from Intel's docs so they seem to have bumped the CDCLK to somewhere past the 605 MHz needed for that res/refresh, but I can't find out what the actual CDCLK is.
- I can't find anything on Skylake.
- Using VESA's timings calculator, it looks like 4096 x 2160 @ 60 Hz/30-bit colour would need a pixel clock somewhere north of 710-715 MHz (fudging the value since there's no bit depth parameter)??? Or is the required pixel clock independent of bit depth?
