Problem Altering Text Size W10

Hi, I'm not sure which forum I need so if this is wrong place please advise me where to post instead.
I altered the text size on my screen W10. The choice was 100 to 500. I picked 400 to try but it is too big and now I cannot access the login bar.
It opens to the login page and shows the 3 logos for internet, ease of access and power. Shows my picture and name but there is no login space. I need to log in to change it again.
Please can someone advise?

 

Right-click the Desktop and click Display settings.

 

You've created a bit of a problem here Jan. I suggest, even though the login box isn't showing, that you try typing in your password followed by Enter or your PIN to see if that gets you in. There are warnings in Settings that if you set text size too high you may have difficulty reverting it.

@Eldon - this is not desktop, it's the sign-in screen and doesn't respond to anything other than signing in.

 

Sorry about that.
I couldn't edit my post and ended up with 4 posts!

 

Thanks Eldon but that won't work.

 

Thanks Earthling
I have tried putting PIN in anyway but there is no box for it and it didn't work.
I'm open to any other suggestions please.
It did say 500 not recommended but that's all. I tried 400 having no idea of the scale involved.

What happens when you select Ease of Access?

 

Thanks everyone but I have managed to fix it. I'm not sure how but after it had been closed down overnight the log in box showed up when I turned it on today. Very large but I was able to alter it back.
Thanks for helping. Jan
