The limit to iterate over a collection on a visualforce page is 10,000 when readOnly attribute is set to true. You can go through the documentation for readOnly attribute to know more details: https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_controller_readonly_context_pagelevel.htm

You will have to implement pagination to work on records more than 10,000.

Yes, Agree by salesforce documentation we can use readonly as true, i used that one also,

Use 2 data tables with 2 different collections as value or

Use nested data tables with Map<Integer, List<DisplayValue>>- first data table iterates the map keys, 2nd iterates the list of display value. Make sure the size of list<DisplayValue>not exceeding 10,000. The next set of 10,000 values you can store in next map key, This way you can display upto 10,000*10,000 values.
