Q: Secondary monitor blurry only when primary scaled
I've scoured the forums looking for a solution to this but have had no luck.
My 2015 Macbook Pro (ATI R9 model) is hooked up to an external 1080P monitor via hdmi. The retina is my primary display, with the external monitor as an extended desktop.
I've been trying to get the display settings adjusted to a workable level under Windows 10 bootcamp, to no avail. What Ive observed:
- With my primary monitor (retina) scaled at 200% (via display settings), my extended monitor (scaled at 100%) is blurry. It is subtle, but there, and causes eye-strain especially with text,
- With my retina display scaled at 100%, the external monitor is sharp. Fonts on the retina are of course too small at this scale to be useable.
Note that in both cases, the scale on the external monitor is not changing - always 100%. I'm only adjusting the scale on the primary monitor.
I've tried every setting I can think of but I always get the same result. For example, just running firefox on the external monitor, the "search or enter address" text is slightly blurry in the 1st case, but noticeably sharper in the 2nd. It seems like a bug: scaling the main display should not affect the secondary one but it does.
Has anyone come across this? Is there some kind of fix or workaround, or am I just doing something wrong? I've ruled out the monitor as a problem given the tests above.
