[LAU] a question reading linux on stage

Hey all, I've been reading with interested that some of you use netbooks/small form factor pc's/rasberry pi's on stage for live performance. I'm currently developing an LV2 plugin and am wondering what the lowest common denomination screen resolution I should be shooting for. During performance, what if anything, do you actually need to see apart from what the the current preset is? Is there a use case for making all parameters for a synth plugin (for example) available/accessible on screen, or using midi learn to hide/unhide parameter tabs etc. Examples of current programs plugins would be great. cheers, Brendan
