so it just doesn't work on the LG 27UD68? What model of Mac do you have (Macbook Pro mid-2013?)?

I have a MacBook Pro 15" mid-2012 and a LG 27UD68 and this patch didn't work, still running at 30hz. =( Funny thing is, I can get 4k 60hz if I boot Bootcamp (Windows 10), but not while running El Capitain. I'm using the HDMI cable that came with the monitor. Any thoughts?

Eu só instalei o FreeTDS, tiny_tds e o activerecord-sqlserver-adapter e coloquei isso no meu database.yml

erp_development: adapter: sqlserver mode: dblib dataserver: 10.211.55.6 database: mydatabase username: sa password: root timeout: 5000

E funcionou. =]

This is the server message:
SystemStackError (stack level too deep):

app/controllers/application_controller.rb:31:in `method_missing_without_create_or_update'

I included this in the ApplicationController and didn't worked. I mean, the server was complaining about the Stack been too long.
I'm using:

authenticate_or_request_with_http_digest(realm) do |username|
User.find_by_username(username).try(:password_check)
end

And something is conflicting. Has to delete the last past:

"def method_missing_with_create_or_update(method_name, *args)
if match = method_name.to_s.match(/create_or_update_by_([a-z0-9_]+)/)
field = match[1].to_sym
create_or_update_by(field,*args)
else
method_missing_without_create_or_update(method_name, *args)
end
end

alias_method_chain :method_missing, :create_or_update "
