Lenovo Legion Pro 7 Gen 9 Display Overscan Fix
Display overscan on the Lenovo Legion Pro 7 Gen 9 appears as a cropped desktop on an external TV or monitor — the edges of the Windows desktop are cut off and hidden behind the screen border. This happens when the display output signal is larger than what the monitor is showing, and is caused by the display’s overscan setting or the AMD GPU scaling configuration.
Disable overscan on the TV or monitor Most effective
On the external TV or monitor, open its menu and look for settings labeled Picture Size, Aspect Ratio, Zoom, or Screen Fit. Change the setting from Auto or Zoom to Just Scan, Native, 1:1, or Screen Fit. These display settings disable overscan at the panel hardware level, showing the complete Windows desktop without cropping.
Fix overscan in AMD Software Adrenalin Edition
Open AMD Software: Adrenalin Edition (right-click desktop → AMD Software). Go to Display tab and find the HDMI Scaling or GPU Scaling slider. Set it to 0% overscan. The AMD RDNA 3 GPU in the Ryzen 9 8945HX uses HDMI Scaling to compensate for TVs that overscan — setting it to 0 tells the GPU to output pixel-perfect with no scaling adjustment needed.
Enable GPU scaling in AMD Software
In AMD Software → Display, enable GPU Scaling and set Scaling Mode to Full Panel. With GPU Scaling enabled, the AMD GPU takes control of resolution scaling instead of the display panel, bypassing the monitor overscan circuit and delivering a pixel-perfect image on TVs that cannot disable overscan natively.
Change the output resolution to match the display native resolution
In Windows Settings → System → Display, set the resolution of the external display to match its native resolution (e.g., 3840×2160 for 4K, 1920×1080 for Full HD). A mismatched output resolution forces the TV to scale, which often triggers overscan. Exact native resolution output eliminates scaling-induced overscan on the Legion Pro 7 Gen 9.
Update the AMD Radeon driver
Go to Lenovo Support, find Legion Pro 7 Gen 9, and download the latest AMD Radeon Graphics driver. Install and restart. AMD driver updates occasionally improve HDMI signal metadata handling that affects how connected TVs interpret the signal boundary, which can resolve overscan that appears after a driver update.
Common questions
Does overscan affect the internal Legion Pro 7 display?
No. Overscan only occurs on external displays (TVs and some monitors) that apply it. The internal 2560×1600 display on the Legion Pro 7 Gen 9 always shows the full desktop without cropping.
Why does overscan only happen on HDMI but not USB-C?
HDMI was originally designed for consumer TVs which applied overscan by default. DisplayPort and USB-C DisplayPort connections typically do not trigger TV overscan modes. If overscan is an issue on HDMI, try the USB-C to DisplayPort adapter output from the Legion Pro 7 Gen 9.
Will using HDMI 2.1 cable fix overscan on the Legion Pro 7 Gen 9?
Not directly. Overscan is controlled by the display settings or GPU scaling, not the cable version. However an HDMI 2.1 cable ensures the signal metadata is transmitted at full quality which can improve how the TV interprets the aspect ratio boundaries.
Does the Legion Pro 7 Gen 9 HDMI port support 4K 144Hz?
Yes. The Legion Pro 7 Gen 9 includes an HDMI 2.1 port supporting up to 4K 144Hz on compatible TVs and monitors. This is one of the few gaming laptops that provide full HDMI 2.1 bandwidth for high-refresh-rate large-screen gaming.
Kamal, Johor Bahru: “My 4K TV showed the Windows desktop cropped on my Legion Pro 7 Gen 9. Setting the TV picture size to Just Scan and the AMD HDMI Scaling to 0% in Adrenalin Edition fixed the overscan instantly.”
Frequently Asked Questions
What does the Lenovo Legion Pro 7 Gen 9 internal display resolution support?
The Lenovo Legion Pro 7 Gen 9 internal display is a 2560×1600 IPS panel at 240Hz. The WQXGA 16:10 aspect ratio provides more vertical space than standard 16:9 1080p or 1440p panels, which is beneficial for productivity and gaming. The internal panel never exhibits overscan as it is driven by the AMD GPU at its native resolution.
Can the Legion Pro 7 Gen 9 run games on a 4K TV via HDMI?
Yes. The HDMI 2.1 port on the Legion Pro 7 Gen 9 supports 4K at up to 144Hz for gaming. The AMD Radeon RX 7900M GPU handles 4K gaming at high settings. After fixing overscan, enable Game Mode on the TV to reduce input lag and set the display to its Gaming or PC Input mode for the lowest latency connection.
Does AMD FreeSync work on external TVs connected to the Legion Pro 7 Gen 9?
Yes, on TVs that support AMD FreeSync Premium or HDMI VRR (Variable Refresh Rate). Enable FreeSync or VRR in the TV menu under Game settings. In AMD Software Adrenalin Edition, enable FreeSync for the connected display. Fixing overscan first is recommended, as some TV modes that disable overscan (like Just Scan) also activate VRR support simultaneously.
Why does the Legion Pro 7 Gen 9 show overscan only at some resolutions?
Many TVs only activate overscan at specific resolutions and frame rates, particularly at 1080p 60Hz (a common TV broadcast resolution). At native 4K or 1440p, the same TV may display the full image. Set the output resolution to the TV native resolution in Windows display settings to avoid the overscan-triggering resolutions.
