The layout on a monitor with 100%:

After moving the form to a monitor with higher than 100% DPI scaling, e.g. 175% or greater:

Hello,

At the core of the problem is using:

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.None;

This will disable scaling logic and is not recommended at all, if you desire DPI scaling.

Instead use the recommended settings:

this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

or

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;
this.AutoScaleDimensions = new System.Drawing.SizeF(96, 96);

It is also highly recommended to have the same setting for all your controls/forms.

For more information on DPI scaling and good practices I suggest checking our updated blog out.

Hi,

In order to achieve better layout, the possible solution that I can suggest is to use a TableLayoutPanel with 3 columns and place the label, textbox and button in each of the columns. You can define fixed size for the first and last column and leave the middle column with 100% to fill the available space:

This improves the behavior on my end when moving the form between the monitors and switching the pages.
