I’m trying to figure out if it might be possible to get NoMachine connecting to my Dell rackmount server running Windows Server 2022 with a better resolution than 1600×1200 – which is the maximum supported by the onboard/integrated iDRAC9 Matrox G200 video chip. Ideally, I’d connect at 4K (3840×2160) which is what my desktop system runs at.
I’m currently using the free NoMachine install on both my local workstation (a 64-core Arm system running openSUSE) and the server, but would be perfectly willing to pay for a different version (as long as it’s not thousands of dollars!) if it would let me connect using a higher resolution or have better graphics. I’ve also wondered about installing a PCIe graphics card in the server and disabling the onboard KVM VGA video: does anyone know if that might work, even if there’s no physical monitor attached to the card?
