You connect your laptop or PC to a TV with an HDMI cable, and the picture appears, but the taskbar is cut off at the bottom and the Start button is hidden past the left edge. On other TVs the opposite happens, with a thick black border around a shrunken desktop. When the Windows 10 desktop doesn’t fit TV screen slot88 properly, the cause is almost always a feature called overscan.

Televisions were designed for broadcast video, where the edges of the picture often contained messy signal information. To hide it, many TVs zoom the image slightly, cropping a few percent from every side. That works for films but cuts off parts of a computer desktop.

Graphics drivers sometimes try to compensate by shrinking the picture, which creates black borders when the TV is not actually cropping anything.

The fix is to turn off the TV’s zoom and, if needed, adjust scaling in the graphics control panel.

What Might Be Causing It

The picture does not fit for these reasons:

• The TV applies overscan, zooming the image beyond the screen edges.
• The graphics driver applies underscan, shrinking the image and adding borders.
• The resolution in Windows does not match the TV’s native resolution.
• The HDMI input is labelled as a video source rather than a PC.

First Steps to Try

Start with the TV’s own picture settings.

1. Open the TV’s picture menu and look for Picture Size, Aspect Ratio, or Screen Fit.
2. Choose “Just Scan,” “Screen Fit,” “Fit to Screen,” “1:1,” or “Original,” depending on the brand.
3. Rename the HDMI input to “PC” in the TV’s input settings if that option exists. Many TVs then switch off processing automatically.
4. In Windows, open Settings > System > Display, select the TV, and set the resolution marked “Recommended.”
5. Adjust Scale if text looks too small; it does not change the fit.

If the Problem Continues

Adjust scaling in the graphics software.

1. On NVIDIA, open NVIDIA Control Panel > Adjust desktop size and position and resize the desktop.
2. On AMD, open AMD Software > Display and change the HDMI Scaling slider until the edges line up.
3. On Intel, open Intel Graphics Command Center > Display and adjust Scale or Custom Scaling.
4. Try a different HDMI port on the TV, particularly one labelled PC or HDMI 1.
5. Update the graphics driver from the manufacturer if the scaling options are missing.

If you see black borders instead of cut-off edges, set the driver’s scaling back to zero and let the TV handle the full picture.

Protect Your Data First

Changing display scaling does not affect files. Avoid using third-party resolution tools to force custom modes, since an unsupported mode can leave the TV with no picture until you reset it.

The Bottom Line

A desktop that does not fit the TV is usually caused by overscan. Set the TV to “Just Scan” or a PC input mode, use the recommended resolution, and fine-tune with the graphics control panel only if needed.
