No, sadly. On linux boxes, I tend to just increase the resolution of the display window. On my machine, I can get sizes in excess of the monitor resolution by having the window hanging off the edge of the screen *before* the "display resize" command.

Think I've worked it out, but can't try it out until at my workstation in a couple of days. Generate the frames using Tachyon and can I then feed the .dat file to TachyonL-OptiX in some manner?

So now having a go at generating a 360 3D animation. Following
instructions at> I can make
one. Looks neat. However, it renders it at the resolution of the
display window, how do I get it to a higher resolution? I must be
missing something simple here ....

With previous 3D animations I would render using Tachyon with the
Movie Generator, render both left and right stereo views separately,
then run Tachyon on the command line with the .dat files to get higher
resolution images, join into videos with the left/right views joined
together. Worked well.

Since using Tachyon-Optix as the renderer, it doesn't output the .dat
file that Tachyon does, just the stereo 360 images that then stitch
together into the video.
