Hardware / Re: Resolution Assistance
« on: May 23, 2023, 03:23:54 pm »I don't have an M93p, but I'm using a lot of Lenovo machines with a 4K monitor with DisplayPort and HDMI inputs. With all the machines, I get 3840 x 2160 resolution for DisplayPort, and 1024 x 768 for HDMI.
I'm using Panorama. I think I tried SNAP, but it didn't do any better. I tried with ArcaOS 5.0.7 and ArcaOS 5.1 beta. Panorama offers what the monitor tells it to offer. Perhaps if you had a better DP-HDMI converter, things would work better. I plan to try the only VGA-DP converter on the market, and I'll report that when it arrives.
It would be nice to have a real video driver for monitors like this one. DisplayPort and HDMI carry Audio as well as Video, and we lack this capability. In practice, I can also use 1920 x 1440, which looks nicer than expected on the monitor.
Thanks for the update, I used your site in configuring it.It may be the adapter itself then // it looks wider on the HDMI (monitor side) so I probably have an active conversion going the wrong way and failing back to passive? Not sure, probably could try some others.
I ended up using a VGA to HDMI converter that has a USB to carry sound as well, have not tested the sound yet.
My resolution now can get up to 1920x1080 but fails when I try the full 4K.
Do you have a link to the DP to HDMI cables you are using? I would love to return this $50 cable and get one that supports 4K.

My Monitor has a DisplayPort input. I use that. I have not found a real working VGA to HDMI converter, but I'm more focused on getting VGA to DisplayPort to work.
My other find, which may or may not be helpful was a Lenovo branded USB-C to DisplayPort adapter. This makes my Lenovo and Dell laptops work well with the monitor.
Sound is also an issue. Without a driver that combines audio and video, I suspect I need a real mixer to do the job.
