I can't believe Microsoft really still hasn't figured out multiple displays at sufficiently different resolutions yet. I fucked up, I shouldn't have gotten the 4K display on the Lenovo P50. Even with Windows 10, either the main display or the external displays end up blurry. For fucks sake.
1. If I leave the main display's resolution to 4K and scaling to 200%, it's perfectly usable (outside of occasional outdated programs that appear tiny, like Launchy). But the display is crisp.
However, my 1920x1200 external displays, which run at native resolution and 100% scaling, now look blurry. They're somehow affected by the fact that the laptop's display is scaled 200%.
2. If I instead set the laptop display to 100% scaling and change the resolution to 1080p (which folds perfectly into 4K in theory), the main display now looks blurry. But the external display is now crisp. Again, seemingly because the laptop is at 100% scaling.
So, there doesn't seem to be a solution where I get no blurriness. Either the laptop ends up blurry or external displays, and that's bullshit.
For comparison, my previous laptop's 1080p display and 1920x1200 external work perfectly fine together and look sharp because both run at 100% scaling.
Ughhhhhhhhhhhhhhhhhhhh. This is grounds for #artemsluck
law return of the whole system unless there's a solution. And to think that I paid $400 extra for the 4K screen (because it had better brightness, gamut, and viewing angle. Btw, it's not even as bright as my E6520's 4-year-old screen).
There's also another issue which causes the P50 to fire up its fan whenever I close the lid and bring it up to the speed of a jet engine. It then starts turning off and back on hyper speed, and I can't figure out what's causing that right now. But the display issues are much more deal-breaking.
