Everything works fine and I'm really enjoying learning Plan 9, however some= monitors don't detect any signal. That is, if I plug into a ~10 year old Vizio tele= vision everything works fine at a reasonable resolution (1280x1024? I haven't yet= figured out which utility to use to query display properties), but if I plug it int= o a Dell S2817Q the monitor says "No signal detected." I've successfully plugged th= e Pi back and forth between the two displays several times and the behavior is consis= tent: everything works fine on the smaller, older Vizio tv, but "no signal" on th= e Dell. Has anyone else experienced anything like this? Any suggestions for things= to try? I would prefer using the Dell monitor to the Vizio tv, but I'm not concerne= d about the resolution. That is, I would happily prefer running Plan 9 on the Pi a= t 640x480 on the Dell rather than the higher resolution on the Vizio. (Ideally, of c= ourse, I would like to run at the highest resolution possible on the Dell, but for t= he time being I'd just be happy with anything working on the Dell) Thank you in advance! ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T295835c4cafb6d4f-Mb8abe= c25c192665db0434e0f Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
