Blurry text since Creators Update.

I know about that, it can be compensated when correctly calibrated.

The critical information you seem to be missing here is that this is a reproducible software bug, specifically with the current Windows 10 Creator's Update preview build. Nothing is wrong with his monitor or its calibration.

Not even all of the text that is being output is gonna be blurry. All the software that's rendering with the correct disposition (edit: which is only some of it, which is the problem) is going to turn out fine, including text on web pages in Chrome as far as I've seen. Changing the calibration or ClearType mode isn't going to help, as some of it will always be wrong (and Windows does not have a grayscale AA mode).

You obviouly know more than me.
I'll stick to my calibrated monitors, using the correct tools, and you can stick to using Windows crappy color management.

I mean, sounds good to me. Calibrating monitors very carefully will indeed get you good looking pixels, but they'll be real sharp jaggy pixels all over your text (without ClearType or its ilk). The only way to get properly subpixel-rendered text is to actually render it in subpixel. If you're outputting hard edges, it's not gonna look good.

I mean, this isn't a color management tool. it's the subpixel font rendering engine (which is screwing up, and making text look worse instead of better half the time).

I've had the exact same issue with my new laptop, installed latest version of Windows - aka CU. Text was blurry here and there. The only solution I've found was the following:

Right click on desktop, select Display Settings, under Scale and layout, I've set 100% (was at 125% by default) to 'Change the size of text, apps and other items'. Hopefully this wont be a long term fix and Windows does something about it.
If you do not see an immediate effect, log off or restart.

Here was my issue with that non-sense issue. File names inside File Explorer got all blurry for no reason. Took forever to figure this one out.

Go to Device Manager > Display adapters > Right click on your graphics card (mine is NVIDIA GeForce GT 710) > Properties
Under the Driver tab, press the Roll Back Driver button. Hopefully you can press that button. If not, uninstall the driver and delete all the files for the update (whenever you see that check box) and reinstall that driver.

If all of that worked, try to search online to ban Windows Update from updating your computer drivers.

If it gets to uninstalling a display driver, go ahead with this:
Go to Device Manager > Display adapters > Right click on your graphics card (mine is NVIDIA GeForce GT 710) > Properties
Under the Driver tab, press the Roll Back Driver button. Hopefully you can press that button. If not, uninstall the driver and delete all the files for the update (whenever you see that check box) and reinstall that driver.

If it gets to uninstalling an external GPU driver, go ahead with this Display Driver Uninstaller Download version 17.0.6.5
Completely removes all traces of the driver, unlike the uninstall option.
As for stopping Windows from downloading the drivers, you would need to skip on connecting to WiFi during the installation of the OS or set your connection as metered.

After the Creators Update (CU) I could barely read any text on my external 2560x1440 monitor (laptop has 1920x1080). I tried 3 different Microsoft support people (one suggested clean boot, no better, other two suggested new drivers, no better). All text was really bad, desktop, apps, browsers, even the icons on the taskbar looked bad, but nothing helped. I asked in MS Windows forum, and received suggestions but no solution. I rolled back CU and everything worked, but then installed it again to try the MS tech ideas.

Today, with a headache from trying to read my screen I decided to drop the monitor to 1920x1080 to see if that would be better. It looked a little better, but I lost a lot of screen real estate, so I tried each higher resolution in turn. When I get back to 2560x1440 everything is crisp and clear, not fuzzy. I can't believe this, so I reboot, and everything is OK.

Sounds like a stupid fix I know, but it worked for me...
