Pros & Cons

Pros

  • ✓ Male-to-female HD15 extends a VGA cord you already own, no full re-run
  • ✓ Handles 1080p plus SVGA, XGA, UXGA, and WUXGA 1920x1200 modes
  • ✓ Integrated ferrite cores cut crosstalk, RFI, and EMI over the 10ft run
  • ✓ Hex nuts mate with existing thumbscrews so the joint will not drift loose

Cons

  • ✗ Not male-to-male, so it cannot connect a PC to a monitor on its own
  • ✗ Will not work on DB9 serial ports despite the similar D-sub shell
  • ✗ Analog only, capped at 1080p/WUXGA, no digital or 1440p+ support
  • ✗ 10ft is the listed length, so longer runs need chaining or a different cable

Manufacturer description

The Cable Matters VGA Extension Cable solves a specific problem: your existing VGA cable is three feet short of where the monitor needs to sit. This 10-foot male-to-female HD15 extender plugs into the end of a VGA cord you already own, letting you move a display across the room, reach a projector ceiling mount, or route cable behind a desk without pulling the whole run. It carries analog video up to 1080p, and supports SVGA (800x600), XGA (1024x768), UXGA (1600x1200), and WUXGA (1920x1200) modes, which covers most CRT and early LCD panels as well as modern LED-lit monitors running a legacy…

SpecPicks Verdict

SpecPicks scored Cable Matters VGA Extension Cable using a rating × review-volume × price-fit model applied to published specs and reviews across the display & crt accessories category. Cable Matters's display & crt accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for display & crt accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Can I use this to connect my computer directly to a monitor?

No. This is an extension cable with a male end and a female end, so it lengthens an existing VGA cord. A direct PC-to-monitor run needs a VGA male-to-male cable, sold separately.

Will this work with a DB9 serial port?

No. Cable Matters states explicitly that this 15-pin DB-15 cable is not compatible with DB9 serial ports, even though the D-sub connectors look similar.

What is the maximum resolution it supports?

Up to full HD 1080p, including 800x600 SVGA, 1024x768 XGA, 1600x1200 UXGA, and 1920x1200 WUXGA. It carries analog video only, so there is no digital or 1440p-and-above path.

Does it reduce picture quality over the extra 10 feet?

Integrated ferrite cores are built in to minimize crosstalk and suppress RFI and EMI on the run.

Will it screw into my existing cable and monitor securely?

Yes. The female end carries hex nuts that mate with the thumbscrews on a standard VGA cable, so the two lock together rather than relying on friction.
