Hi,
Thank you for sharing your question. I understand how confusing it is when you try to select text in Word 2024 and only one line appears highlighted even though the rest of the text is technically selected. It can be frustrating when the visual highlight doesn’t match what Word is actually doing, especially when you need to edit multiple lines at once.
This behavior usually happens when Word’s display settings or graphics acceleration features are not rendering the selection correctly. In many cases, the issue is caused by a compatibility problem with the graphics driver or a display mode that prevents Word from showing multi‑line selections. Turning off hardware graphics acceleration, updating your display driver, or switching Word to a different view (such as Print Layout) usually restores proper multi‑line highlighting, and repairing Office can also rebuild display components when they become corrupted.
To better understand the cause, does the issue happen in every Word document or only in a specific file, and has your device recently installed a Windows or display driver update? That will help narrow down whether this is a rendering issue or document‑specific corruption.
Feel free to follow up anytime, and I’ll be happy to guide you step‑by‑step until Word shows your full text selection normally again.
I hope this helps.
Best Regards,
Noel
