So I just bought a laptop with a 4k display and have noticed issues with the SolidWorks UI. I'm using Solidwork 2016 SP3, and I noticed the text seems to be incorrectly sized. I have tried text scaling in windows as well as resizing the icons in SolidWorks to no avail. I've looked at other posts but no one seems to have the same issue where the text is incorrectly sized. Any help would be awesome, thanks.
Oh, yes I meant to say 2015 SP3. Thanks for answering my question though, I guess I'll just have to put up with my screwed up display or upgrade..
Cody,
There may be a few options. What OS scaling level are you using? Check Control Panel\Appearance and Personalization\Display. Also what is the monitor size?
We have the text size setting in 2015 under Tools>customize that may allow you to tweak things a little bit. 
Thanks! I tried that and while it made it lessened the issue, it still persisted. However... I was able to fix the problem by changing my computer DPI settings in the registry editor. Looks like I won't need to get 2016 after all.
Out of curiosity, What did you change in the registry? Usually you can change the dpi through control panel.
Hopefully someone else find this useful as well:
Start -> Type in regedit and press enter -> Go to HKEY_CURRENT_USE\Control Panel\Desktop -> Find WIN8DpiScaling on the right side, double click, and set value to 1. -> Restart Computer.
I did try changing settings first through Control Panel to no avail, but this seemed to do the trick for me.
Hi Cody,
That registry key controls this setting: "Let me choose one scaling level for all my displays." You probably don't have to hack the registry to get it to work through Control Panel.
That setting is interesting, in that Windows tries to scale each of your monitors independently based on what it thinks is the best size. Sometimes odd results can happen. SOLIDWORKS 2016 should play better with this setting, but it seems like you have a decent workaround for 2015 for now.
Thanks for posting.
This Worked for me with slightly blurred Font.
Great workaround!
As you experienced, the font is slightly blurred on the 4K laptop screen. However, I don't notice it on the 22" dual monitors that I use at work (but they are old 1080 displays). I thought a 4K display would be a nice addition to our new company laptops, but it's more of a pain in the a$$ than I would have ever imagined. This laptop is about to go back, because nobody should have to find a workaround for new technologies that are being shoved down our throats like they are the next greatest thing. SolidWorks should have addressed this issue long ago. They have too many customers on a maintenance plan that should have funded this fix immediately after the first 4K monitors came into existence 5 years ago.
Hi Cody,
Your screenshot is from 2015, did you mean 2015 SP3 or 2016 SP3? Unfortunately, 2015 can be a bit unforgiving in that regard. 2016 has significant changes to make text and icon scaling work much better on high density displays (as 4k displays often are).
