How to improve map and three map views?

[Akmatov]

Was just watching a video in hopes of learning how to play and the map was much much better than what I'm seeing in exactly the same scenario. I have flat green for woods, he had trees. He mentioned that he had improved his game somehow, didn't mention how. How can I improve the map from the 1980's? Also, zoom into the same mag, his game is clear and mine if blurry. Not good.

Went back to game and now there are THREE different maps I've seen:
1. Flat terrain with little NATO symbols in blue circles, FIXED
2. Flat terrain with big vehicle icons - no idea how that happened, just went back to the game, FIXED
3. Textured terrain with little NATO symbols - on video. PARTLY FIXED, NO IDEA HOW.

What is going on?

UPDATE:
Messed around with the various Graphic Options, never got what I wanted, exited and restarted a new game and the graphics of the map were much better. I lost the markers for the fords, but much better map AND not the map I got messing with the Graphics Options, but something new. No idea how this happened, so can't repeat it.

The 'Map detail distance' graphics option adjusts the zoom level where the detailed textures and the generated map image are switched.
