I observe different problems with OS/2 video output nowadays.

1) The BIOS decides which output is to be uses or not. Not used are sometimes switched off here. F.i. when  at boot the HDMI output is attached on my RX550 (?) the Display Port output is switched off. And vice versa. When both are attached I think DP is used and HDMI is switched off. But when something is attached to the internal Intel GPU (DP or HDMI or VGA) in parallel to the outputs of the extra graphic card, things go to complicated to describe very fast.
 
2) Integrated Intel GPU on my system does work but not with 4k. So it's kind of useless on my 3840x2160 Monitor. Needed to put in a extra graphic card and needed a ticket and work from David A. to get this card to work at full resolution.

3) Ryzen 7 integrated GPU does not work in 4k with ArcaOS too. Of course it works with the other OSes I've installed. No clue if David can fix this, need to create a ticket for that.

4) Output (DP or HDMI) is switched off when I switch the KVM to another source. But it is not switched on again when I switch back to ArcaOS. So you don't see any output anymore from your running system until reboot. Of course the other OSes switches back on the output (tested with DP and HDMI on Ryzen 7) when the KVM switches to that input.

There are even more problems with video on our platform I don't wanna go into detail. Some of them are nice to have things which result from the way we are used to work nowadays. But the above are the most annoying.

Eugene Tucker:
I just bought a 24 inch Asus VA24D and it is working fine. It has a display port and a HDMI port it also has a VGA port sorry no DVI port. I got the monitor from Amazon. I did get a Monitor from New Egg it was an LG and it only had HDMI ports. I sent it back as I use Display port. The video chip is in my AMD processor.

Per E. Johannessen:
I'm now testing;

GPU: Asus Geforce RTX 4060 Ti 16GB, (Nvidia).
Monitor: Samsung Odyssey G8 G80SD 32" 4K OLED.
Connection: HDMI

Max resolution offered by Panorama is 1280x1024.

Is there a "safe" way to get a higher resolution or do I simply have to experiment.

Change video cards? Nvidia is known to not be friendly with no way to patch its BIOS for higher video resolutions. You could open a ticket but I think you will be told the same thing.

My tests with a new system tought me to -
- better use AMD
- better use DisplayPort
- don't connect both (or 3) outputs at the same time (DP, HDMI, DVI VGA) especially from cold boot.
- don't disconnect output from monitor, don't use KVMs (no KVM works here reliable either DP nor HDMI)
- HDMI output here only offers 1400 x 1050 sometimes. When DP is connected too it magically offers full 3840x2160 but system traps when selected afterwards while boot.  Of course I use short high quality cables only.
- DP usually offers full resolution (or most complete list)
- Panorama with integrated AMD Ryzen only offers 2560x1440 altough the system runs 3840x2160 perfectly well with other OSes (except Win7 which only can do 2560x1440 cause Ryzen 7 is not supported anymore with AMD Win7 driver).
- AMD RX550 works better with Panorama (and Win7) then integrated GPU
- 3840x2160 on one system (UEFI) leads to trap 000e in VMAN while 2560x1440 works.

You can also look at the tickets in mantis to find the log file of video (gradxx?) which is written at boot up to see what Panorama driver has to say. Or look into 'testlog generic' output.
