Used 20 Inch LCD Monitor: Top 7 Buying Tips and Best Deals for 2025

If you are looking for a cost-effective and space-saving display solution, a used 20 inch LCD monitor remains a highly practical choice in 2025. These monitors offer a balance of adequate screen real estate for office work, basic graphic design, and point-of-sale systems without the premium price of larger or newer models. This article provides a comprehensive guide to help you evaluate, purchase, and get the most value from a pre-owned 20 inch LCD monitor.

1、used 20 inch LCD monitor price

Understanding the current market price for a used 20 inch LCD monitor is crucial for making a smart purchase. As of 2025, the price range for these monitors varies significantly based on brand, condition, resolution, and included features. On average, a standard 20 inch LCD monitor in good working condition with a 1600x900 resolution can be found for between $30 and $60 on secondary markets like eBay, Craigslist, or local recycling centers. Higher-end models from brands like Dell, HP, or Lenovo, especially those with an IPS panel or a DVI input, might command a slightly higher price, often ranging from $50 to $80. Monitors sold as "refurbished" or "grade A" by certified sellers typically cost more, around $60 to $90, but come with a warranty and guarantee of no dead pixels. It is important to compare prices across multiple platforms and check for shipping costs if buying online. For bulk purchases, such as for an office upgrade or a school computer lab, the per-unit price can drop significantly to around $20 to $35 per monitor. Always factor in the cost of a power cable and a VGA or DVI cable, as these are sometimes not included with used units. The price also drops if the monitor has minor cosmetic scratches or a slightly yellowed bezel, but the panel itself should be free of burn-in. Setting a budget of $40 to $60 will generally secure a very reliable 20 inch LCD monitor for general use.

2、refurbished 20 inch LCD monitor

A refurbished 20 inch LCD monitor offers a middle ground between a brand-new unit and a strictly used one. These monitors have typically been returned to the manufacturer or a certified refurbisher, inspected, repaired if necessary, and tested to meet original specifications. Purchasing a refurbished 20 inch LCD monitor is often a safer bet for businesses and individuals who need reliability but want to save money. Refurbished units usually come with a warranty, often 90 days to one year, which is a significant advantage over buying a used monitor "as-is." They are also cleaned and repackaged, often looking nearly new. The price for a refurbished 20 inch LCD monitor is generally 20-30% higher than a comparable used model but still 40-60% less than a new one. For example, a refurbished Dell 2007FP, a classic 20 inch 4:3 monitor with an IPS panel, can be found for around $70 to $90. It is important to buy from reputable sources, such as Dell Outlet, Newegg Refurbished, or Amazon Warehouse, to ensure the refurbishing process was thorough. Beware of sellers who label a used monitor as "refurbished" without any certification or warranty. When buying a refurbished 20 inch LCD monitor, always check the return policy and the specific grade (A, A-, B) which indicates the level of cosmetic wear. Overall, a refurbished 20 inch LCD monitor provides excellent value for those who prioritize performance and peace of mind over the absolute lowest price.

3、cheap 20 inch monitor used

Finding a cheap 20 inch monitor used is entirely possible if you know where to look and what to accept. The term "cheap" in this context usually means a price under $30. At this price point, you are likely to find older generation monitors, often from around 2005 to 2010, with lower resolutions like 1600x900 or even 1440x900. These monitors typically only have VGA inputs, which are still compatible with most modern computers via a VGA port or an adapter. The cheapest options are often found on local classifieds like Facebook Marketplace, Craigslist, or at local thrift stores and electronic recycling centers. You can often pick up a basic HP or Acer 20 inch LCD monitor for $15 to $25. However, when buying a cheap used monitor, you must carefully inspect the screen for dead pixels, stuck pixels, or backlight bleeding. Also, check that the buttons on the bezel work properly and that the stand is not broken. Many cheap monitors are sold "as-is" with no returns, so testing it on the spot is highly recommended. Bringing a laptop with a VGA output to test the monitor before purchasing is a smart strategy. For businesses needing many monitors for a low budget, buying a pallet of cheap used 20 inch monitors from a surplus auction can bring the cost down to $10 per unit. While a cheap used monitor may not have the best color accuracy or the thinnest bezel, it is perfectly adequate for secondary displays, surveillance camera feeds, or basic office tasks.

4、20 inch LCD monitor VGA

A 20 inch LCD monitor with a VGA connection is one of the most common types found on the used market. VGA, or Video Graphics Array, is an analog video standard that has been around for decades. While it is an older technology, it is still widely supported on many motherboards, projectors, and older computers. For a used 20 inch LCD monitor, the VGA port is often the primary or only input option. This is particularly true for budget models produced before 2010. When choosing a 20 inch LCD monitor VGA model, you should be aware that the analog signal can be susceptible to interference, leading to a slightly softer image compared to a digital connection like DVI or HDMI. However, at the 1600x900 resolution typical of a 20 inch monitor, the difference is often negligible for everyday use like web browsing, email, and document editing. Many users pair a used 20 inch LCD monitor VGA with a laptop or a desktop that has a built-in VGA port, requiring no adapter. For modern graphics cards that lack VGA, a simple and inexpensive VGA to HDMI or VGA to DisplayPort adapter works perfectly. When inspecting a used VGA monitor, check that the VGA connector is not bent or missing pins. Also, test the monitor with a known good VGA cable to ensure there is no flickering or color distortion. In summary, a 20 inch LCD monitor with VGA is a reliable and affordable choice for basic computing needs.

5、20 inch monitor DVI used

A used 20 inch monitor with a DVI connection offers a significant step up in image quality compared to a VGA-only model. DVI (Digital Visual Interface) provides a pure digital signal from the computer to the monitor, resulting in sharper text, more accurate colors, and no analog interference. This makes a used 20 inch monitor DVI model ideal for graphic design, photo editing, and any task where visual clarity is important. Most high-quality 20 inch monitors from brands like Dell, Samsung, and LG from the mid-2000s to early 2010s include a DVI-D (digital) or DVI-I (digital and analog) port. The resolution on these monitors is typically 1680x1050 (widescreen) or 1600x1200 (4:3 aspect ratio). The Dell 2007FP and 2007WFP are legendary examples of excellent used 20 inch monitors with DVI that are still highly sought after. When buying a used 20 inch monitor DVI, check that the DVI port is not damaged and that the monitor includes the DVI cable, as these cables are slightly more expensive and less common than VGA cables. DVI is also backwards compatible with HDMI via a simple passive adapter (for DVI-D to HDMI), allowing you to connect modern devices like a game console or a streaming stick. However, DVI does not carry audio, so separate speakers are needed. For users building a dual-monitor setup, two used 20 inch DVI monitors can be an excellent and affordable configuration. Overall, a used 20 inch monitor DVI is a high-value purchase for anyone wanting a crisp, digital display without spending much money.

6、buy used 20 inch monitor

Deciding to buy used 20 inch monitor is a smart financial decision, but it requires some due diligence to ensure you get a good unit. The first step is to determine your primary use case. For office work, any model in good condition will suffice. For gaming or video, look for a model with a DVI input and a faster response time (5ms or less). Once you know what you need, the best places to buy used 20 inch monitor include eBay (with buyer protection), Craigslist (for local pickup and cash deals), and Facebook Marketplace (for local deals). Certified refurbished sellers on Amazon or Newegg are also excellent options, offering warranty and return policies. When you find a listing, always ask the seller for a photo of the monitor turned on, displaying a solid color (like white or blue) to check for dead pixels. Also, ask about any scratches on the screen, the condition of the stand, and whether the original power adapter is included. For local purchases, always test the monitor before handing over the cash. Bring a laptop or ask the seller to demonstrate it. Check that all the buttons work, that the screen is bright enough, and that there is no noticeable yellowing or burn-in. Finally, consider the brand. Dell, HP, Lenovo, and Samsung are generally reliable. A used 20 inch monitor from these brands can easily last for several more years. By following these steps, you can confidently buy used 20 inch monitor that meets your needs and budget.
