MacPro monitor setup with LG 34" problem.
I bought a Macpro and decided to use a 34" LG monitor which is ultra wide and has a thunderbolt port. I couldn't get the monitor to work depite connecting via the thunderbolts. I tried connecting via the HDMI ports too but the screen doesn't boot. I can change settings of the monitor and it looks like it's ok. the LG monitor was advertised as MacPro ready so I bought it rather than the very expensive 4K monitors. I'd appreciate any help or suggestions. Thanks.
