Subject: Cursor remains extremely small on 27-inch 4K monitor despite all available scaling settings

I would like to report a HiDPI scaling issue in Adobe InDesign 2026 that affects usability on professional 4K monitors.

My setup consists of two displays connected to the same Windows PC:

• ASUS ProArt PA279CRV – 27-inch, 3840 × 2160 (4K)
• KOORUI 27-inch – 1920 × 1080 (Full HD)

When InDesign is displayed on the KOORUI Full HD monitor, the text cursor (insertion point) appears at a normal and comfortable size. However, when I move the exact same InDesign window to the ASUS ProArt PA279CRV 4K monitor, the cursor becomes extremely small and difficult to see.

I have already tested all available scaling-related options without success:

• Windows display scaling at multiple values, including 100%, 125%, 150%, 175%, 200%, and higher available settings.
• InDesign Preferences → User Interface Scaling → UI Sizing set to Large.

• Windows Compatibility settings:

  • Application
  • System
  • System (Enhanced)

• Restarting InDesign after each change.

None of these settings significantly improve the cursor size on the 4K display.

It is important to note that the Windows cursor itself scales correctly and remains clearly visible throughout the operating system. The issue appears to be specific to InDesign’s text insertion cursor. The behavior can be reproduced instantly by simply moving the InDesign window from the Full HD monitor to the 4K monitor, without changing any other settings. This indicates that the problem is related to how InDesign handles HiDPI scaling on 4K displays.

Because both monitors are 27 inches, the physical size difference is not caused by screen size but by the much higher pixel density of the 4K display. As a result, the insertion cursor becomes disproportionately small compared to the rest of the interface.

I would also like to emphasize that reducing the monitor resolution is not an acceptable workaround. I specifically purchased the ASUS ProArt PA279CRV for professional graphic design, catalog production, image editing, and color-critical work at its native 3840 × 2160 resolution. Lowering the resolution defeats the purpose of using a professional 4K monitor.

I kindly request that Adobe review and improve the scaling behavior of the text insertion cursor in InDesign on HiDPI and 4K displays, or provide a dedicated option to independently adjust cursor thickness and visibility.

Thank you for your time and consideration.
