4K resolutions are upcoming and I've heard several people with such monitors complain about the chat (character/font) size being too small.

My own monitor is an old HD-ready TV and is showing the opposite issue, but either way, having the ability to increase (and decrease) the chat-size would be greatly welcomed by a large portion of the player-base.

This thread is welcoming additional cheering as I find it strange I found no similar thread on the forum (using the google trick described on the forum elsewhere).

Yea having the ability to manually scale the UI with a slider or something would be very nice. especially on larger resolutions which are slowly becoming more common. I support this suggestion 100%
