Big, blurry content on external screen with MacBook Pro Retina 15" running Win7

Problems with big and blurry content on external screen when plugged in to a MacBook Pro Retina 15" running Windows 7.

I'm running Windows 7 (bootcamped) on my MacBook Pro Retina 15", using a resolution of 2880x1800 on the laptop – plus one extra monitor (a SyncMaster 245B), with its maximal setting of 1920x1200.

I’m using the option "Make text and other items larger or smaller" to make the laptop experience more comfortable for my eyes, setting it to 150%. Sadly, that also makes the scaling on the external screen blurry and ridiculously blown out of proportion – as that monitor can't handle the scaling.

This is not a problem if I'm using MacOS; it's just Windows not getting it. I haven't yet found a way to solve this (well, apart from only using MacOS, but I can't do that). Is there some setting to be hacked or some kind of program I can run to make the external monitor and the laptop look okay at the same time? Or is there a monitor I can get, that won't have this problem? Or anything, really... I'm so tired of looking at this large and blurry content.

Ridiculously large text on external monitor when the retina is set to scale to 150%.

(And no, it's not that I'm "used to the retina and just imagine the blurriness".)

The resolution used.

I'm "extending" the screen, if that's what you mean. I use the recommended resolution for each monitor.



I think, as I wrote, that it's the scaling that's confusing the drivers. Two different resolutions are completely manageable. But there isn't an option for two different scalings. (And running 100% on the rMBP is really not an option for my eyesight. )

Was hoping someone had come up with an upgrade, addon, hack or something to solve this...

(Thanks for moving my post, btw. )
