Windows 10: Fonts really blurry on one monitor

Have a user with a Sony vaio laptop, 15" screen, 1920x1080. They also plug an HDMI cable into a 23" dell widescreen monitor for a second display. This 23" monitor is also 1920x1080. They are complaining that fonts on this second monitor are blurry. They tried to live with it a week but they said can it be made clear again like it was when they had Windows 7?

Are you familiar with the possibility of fonts being blurry only on one monitor if they are both set to the native?

I'm asking them to see if they change the font dpi to 100%, logoff and on if its any better. For whatever reason that seemed to work for my laptop (another Sony Vaio), but my concern is they will be disappointed at legibility on the laptop screen (it makes everything tiny).

windows 10 two monitors

When I hook a second monitor to windows 10, desktop icon fonts become blurry.

One of the icons is remote desktop. The fuzzy font is then also on the remote desktop after logging on to it.

Run WINVER to see exactly which build number you have. 16299.192 is current.

Is this a problem with the whole monitor or with specific applications?

What types of GFX does this laptop in question have? I know I had problems with my Sony Vaio laptop, basically used it a as home cinema system. Plugged into a 32" TV in the bedroom. I had the same issue with texts on web pages, but the video on fullscreen was perfect.

If I remember rightly a latest driver update for intergrated graphics that worked for me but a friend just told me who I am working with right now that, go into the control panel and check the MHZ of the 2nd Screen and check if they are below 60mhz, if thats all fine try changing the resolution downscaling it, then put it back up to 1980 x 1020.

Hope it Helps.
