Hardware / Displayport?
« on: August 05, 2022, 07:34:37 am »
So this computer I'm using has a Sandybridge/Ivybridge graphics controller with a VGA and a Displayport ports, monitor has VGA and DVI ports and supports 1920x1200 as its native resolution.
For quite a while I was simply using the VGA connection, everything worked fine but slightly blurry.
Then I came across a Displayport to DVI passive connector so I tried that.
While the graphics were sharper, especially text mode, I came across these limitations. The screensaver would put the monitor to sleep but it would not wake up, forcing a reboot to awaken it. Same with SNAP and Panorama. Nothing I tried helped here, worked fine under Linux, which reported a HDMI connection. The other thing was I tried using Xfree86 using the VESA (VBE) driver, it simply did not find a graphics card at all, which was weird. Works fine with the VGA connector and an older Panorama/SNAP, newer ones seem to have done something to support UEFI where switching back to the WPS fails, a bit of drawing and then a full hang.
Just wondering about others experience with Displayport and OS/2. Perhaps a monitor that supports Displayport would be better, it seems that Displayport falls back to a DVI compatible protocol when used with a passive converter.
