You may find this post and thread breeminator links to there (titled, “PSA: How to zoom out more with an Nvidia graphics card ” helpful:
From another thread, these all give the same view of the map:
1080p, non-enhanced, 100% zoom. Benchmark score 1229
1440p, non-enhanced, 50% zoom. Benchmark score 1229
2160p, enhanced, 75% zoom. Benchmark score 1179
IMO 1440p non-enhanced is the sweet spot for competitive use, as it avoids the performance hit of using enhanced, while giving good ability to zoom out. A 4k screen with enhanced both reduces performance and gives less ability to zoom out than 1440p non-enhanced.
As an example, I was able to achieve this on 1920x1200 using his PSA! Which is a LOT more than what I saw at the furthest zoom normally. This is very similar (or equivalent?) to the area that like 4K monitors might see:
