raised a common question about keeping Windows form controls positioned correctly across different resolutions. Replies from (centering tips) and (automatic-scaling reference) are useful starting points. A pragmatic, reliable strategy is: prefer layout-managed placement (anchors/dock, TableLayoutPanel/FlowLayoutPanel) for structure, then enable DPI-aware scaling for differences in pixel density and font settings. (learn.microsoft.com)

Use layout panels instead of absolute coordinates. Example pattern (construct at runtime or configure in the designer):

var table = new TableLayoutPanel();
table.Dock = DockStyle.Fill;
table.ColumnCount = 2;
table.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 50F));
table.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 50F));
table.RowCount = 1;
table.RowStyles.Add(new RowStyle(SizeType.Percent, 100F));
button1.Dock = DockStyle.Fill;
table.Controls.Add(button1, 0, 0);
Controls.Add(table);

This keeps controls proportional as the form resizes and avoids pixel-by-pixel repositioning.

For pixel-density differences, rely on Windows Forms automatic scaling and modern DPI features rather than manual math. Set AutoScaleMode to Dpi (or Font if the UI is font-driven) and target a runtime that supports per-monitor DPI behavior when needed. Recent Windows Forms improvements are opt-in (application manifest/app-config + targeting .NET Framework 4.7 or later) and include helpers like LogicalToDeviceUnits and bitmap-scaling helpers for images. Test at 100%, 125%, 150% and on multi-monitor setups. (learn.microsoft.com)

For new projects, prefer WPF (device-independent units) or a modern UI framework: WPF measures in device-independent pixels (DIPs), which makes resolution/DPI handling simpler out of the box. For bitmap assets, supply vector icons or multiple raster sizes to avoid blurriness when Windows or the app scales UI elements. (learn.microsoft.com)
