You’ve got a secondary monitor sitting there with just an HDMI port, but your laptop or PC only has DisplayPort out. It’s a classic problem, and I’ve spent hours testing nine of the top-rated adapters to find which ones actually work without dropouts, flicker, or weird color issues. These are all passive, unidirectional cables and dongles that convert DP 1.2 to HDMI 1.4 or 2.0.
Every product on this list had to meet three criteria: stable 4K output at 30Hz or higher, solid build quality that won’t break after a few plug-ins, and verified compatibility with common brands like Dell, HP, Lenovo, and AMD or NVIDIA graphics. I also prioritized products with strong user ratings and a clear track record of reliability.

How I Selected These Products
I focused on passive, unidirectional adapters that convert DisplayPort 1.2 to HDMI. Every candidate had to support at least 4K resolution and work reliably with common graphics cards from AMD and NVIDIA. I also checked for gold-plated connectors to ensure a stable signal path.
Value mattered too, so I compared build quality against price without recommending anything flimsy. Real-world usability like cable length, latch-free plugs, and compact size influenced the rankings. I wanted adapters that actually fit behind a desk without hassle.
Finally, I dug into thousands of user reviews to spot recurring issues like flickering or compatibility problems. Products with consistent 4.4-star or higher ratings and clear track records made the cut. I avoided anything with reports of early failure or signal dropout.

I’ve tested dozens of adapters, and the BENFEI 4K DisplayPort to HDMI Adapter is still the one I recommend most. It’s a simple passive dongle that converts DP 1.2 to HDMI 1.4, and it handles 4K at 30Hz without any flicker or signal drop. With over 65,000 ratings and 8,000+ bought in the past month alone, it’s clearly the crowd favorite for a reason.
This adapter is best for anyone who wants a no-brainer solution for a secondary monitor. My only gripe is that it only supports HDMI 1.4, so you won’t get 4K at 60Hz — but for a secondary display, 30Hz is perfectly fine for productivity work.
✅ Pros
- Proven reliability with 65,000+ ratings and 4.5 stars
- Gold-plated connectors for stable signal transfer
- Works with Lenovo, Dell, HP, and most passive setups
- Compact dongle design that won’t block adjacent ports
❌ Cons
- HDMI 1.4 limits you to 4K at 30Hz only
- No latch on the DisplayPort end can feel loose on some PCs
Best for 4K @ 60Hz

- WIDE COMPATIBILITY: Perfect for graphics card (AMD, NVIDIA), desktops (HP, Dell, Lenovo) with...
The Highwings 4K Display Port to HDMI Adapter is a step up if you need smoother motion on your secondary monitor. It uses HDMI 2.0, which means you get 4K at 60Hz instead of the usual 30Hz. The SR Anti-Break design and no-latch plug make it much tougher than most adapters I’ve handled.
This is the one to grab if your secondary monitor supports HDMI 2.0 and you want fluid video playback or light gaming. The downside is that the braided cable is a bit stiff, so you’ll need to route it carefully behind your desk.
✅ Pros
- HDMI 2.0 support delivers 4K at a smooth 60Hz
- SR Anti-Break reinforcement for long-term durability
- No-latch plug makes removal quick and easy
- Amazon’s Choice with 6,000+ bought in past month
❌ Cons
- Braided cable is stiff and harder to bend tightly
- Only 2,913 ratings — less proven than the BENFEI

If you prefer a cable over a dongle, the WARRKY 4K DisplayPort to HDMI Cable is my top pick. It’s a full 6-foot cable with a metal case and nylon braiding, so it feels premium and survives daily abuse. It’s still passive DP 1.2 to HDMI 1.4, giving you 4K at 30Hz, but the extra length is a lifesaver for monitors placed farther from your PC.
This is ideal for desktop setups where your secondary monitor sits across the desk. The trade-off is that the 6-foot length can create clutter if you only need a short connection, and the nylon braid isn’t as flexible as rubber cables.
✅ Pros
- 6-foot cable gives you plenty of reach for any desk
- Metal case and nylon braid for serious durability
- Amazon’s Choice with 26,558 ratings and 4.6 stars
- Works with NVIDIA, AMD, Dell, and Lenovo systems
❌ Cons
- Only HDMI 1.4, so 4K maxes out at 30Hz
- Nylon braid is stiffer and harder to manage in tight spaces

- 【Plug and Play】This DisplayPort to HDMI adapter works only from DisplayPort (DP, DP...
The IIABC Displayport to HDMI Adapter is the cheapest option on this list that still delivers solid performance. It’s a bare-bones dongle with 24K gold-plated contacts, and it handles 4K at 30Hz without any drama. With 3,878 ratings and 4.6 stars, it punches well above its price point.
This is perfect if you’re on a tight budget and just need your secondary monitor working. Just know the build feels a bit plasticky compared to pricier options, and the lack of a latch means it can wiggle loose if your desk gets bumped.
✅ Pros
- Budget-friendly without sacrificing 4K support
- 24K gold-plated connectors for corrosion resistance
- Compact size fits easily behind a monitor
- Works with Lenovo, HP, Dell, and more
❌ Cons
- Plastic housing feels less durable than metal options
- No latch on DP end — can disconnect if bumped

The KUXIYAN 4K DisplayPort to HDMI Adapter 2-Pack is a fantastic deal if you need to connect multiple secondary monitors. You get two passive adapters with 24K gold plating, and each one supports 4K at 30Hz. It’s an Amazon’s Choice pick with over 1,000 units sold in the past month.
This is the way to go if you’re setting up a dual-monitor secondary display or need a spare for travel. The catch is that each adapter only supports HDMI 1.4, so you’re stuck at 30Hz, and the rating count of 1,420 is lower than the top picks.
✅ Pros
- Two adapters for the price of one — great value
- 24K gold-plated for reliable signal transmission
- Works with HP, Dell, AMD, NVIDIA, and projectors
- Amazon’s Choice with 1,000+ bought in past month
❌ Cons
- HDMI 1.4 limits you to 4K at 30Hz
- Only 1,420 ratings — less proven than top competitors

The Amazon Basics DisplayPort to HDMI Cable is exactly what you’d expect from the name: no frills, but it gets the job done. It supports 4K at 60Hz, which is rare for a cable at this price point, and the 6-foot length gives you solid reach. With a 4.5-star rating from 3,378 reviews, it’s a dependable choice for a secondary monitor.
This cable is best if you want a simple, long-lasting connection without any extra bells and whistles. The downside is that it’s not as rugged as braided options, and the rubber jacket can kink if you bend it too sharply during setup.
✅ Pros
- Supports 4K at 60Hz for smoother visuals
- 6-foot cable length gives you plenty of flexibility
- Gold-plated plugs for corrosion resistance
- Solid 4.5-star rating from over 3,300 users
❌ Cons
- Rubber cable jacket can kink if bent too tightly
- No braided reinforcement for added durability

- SUPERIOR STABILITY: DisplayPort locking connector with latches prevents accidental disconnection...
The Moread 4K DisplayPort (DP) to HDMI Adapter is a tiny, passive dongle that I’ve found works reliably with HP, Dell, and Lenovo laptops. It’s gold-plated for stable signal transfer and delivers 4K at 30Hz without any fuss. With over 4,400 ratings and a 4.6-star average, it’s an Amazon’s Choice pick for good reason.
This is perfect if you need a compact adapter that won’t stick out far from your laptop’s DisplayPort. The limitation is that it’s HDMI 1.4 only, so you’re capped at 30Hz for 4K — fine for office work, but not ideal for video playback.
✅ Pros
- Compact dongle design won’t block nearby ports
- Gold-plated connectors for reliable signal quality
- Amazon’s Choice with 4,410 ratings and 4.6 stars
- Works with HP, Dell, Lenovo, and more
❌ Cons
- HDMI 1.4 limits 4K to 30Hz max
- No latch on the DP end — can disconnect if bumped

- High-Resolution Performance: Delivers crystal-clear visuals up to 4K@30Hz (3840x2160) 2K 1440p@60Hz...
The Mbiydeg DisplayPort to HDMI Adapter 4K 30Hz is the cheapest way to connect multiple secondary monitors. You get three passive adapters in one pack, each supporting 4K at 30Hz, and they work with laptops, PCs, monitors, and TVs. It’s an Amazon’s Choice pick with over 500 units sold in the past month.
This is the one to buy if you’re outfitting a whole office or need spares for different rooms. The trade-off is that each adapter only does 4K at 30Hz, and with only 230 ratings, it’s the least-tested product on this list.
✅ Pros
- Three adapters for an unbeatable per-unit price
- Supports 4K at 30Hz for office and streaming use
- Amazon’s Choice with 500+ bought in past month
- Works with laptops, PCs, monitors, and TVs
❌ Cons
- Only 230 ratings — less proven than competitors
- HDMI 1.4 caps 4K at 30Hz only

The UGREEN 4K DisplayPort to HDMI Adapter is a short, braided cable that’s built to last. It’s only 0.66 feet long, which makes it perfect for tight spaces where you don’t want cable clutter. It supports 4K at 30Hz and works with AMD and NVIDIA graphics cards, earning it an Amazon’s Choice badge with 855 ratings and 4.6 stars.
This adapter is ideal for connecting a monitor that sits right next to your laptop or desktop. The short length is a double-edged sword though — if your monitor is more than a few inches away, you’ll need an extension or a different product entirely.
✅ Pros
- Braided cable for extra durability and tangle resistance
- Ultra-short 0.66 ft length minimizes cable clutter
- Amazon’s Choice with 4.6 stars from 855 ratings
- Works with AMD and NVIDIA graphics cards
❌ Cons
- Only 0.66 ft long — too short for distant monitors
- HDMI 1.4 limits 4K to 30Hz max
What to Look for in DisplayPort to HDMI Adapter for a secondary monitor that only has HDMI input
Picking the wrong adapter can leave you with a flickering screen or no signal at all, which defeats the whole point of adding a second monitor. I’ve seen people grab the cheapest option only to find it doesn’t support their resolution or is an active adapter when they need passive. Here’s what actually matters when you’re shopping.
Passive vs. Active Adapters
For a secondary monitor with HDMI input, you almost always want a passive adapter. Passive adapters are cheaper, smaller, and simply convert the DisplayPort signal to HDMI without extra electronics. The catch is that they only work if your DisplayPort source can output a single-link DVI or HDMI signal — which most modern laptops and desktops can. If you’re using an older GPU or a dual-mode DisplayPort setup, a passive adapter is all you need.
Resolution and Refresh Rate
Check what resolution your secondary monitor supports and match the adapter to it. Most adapters on this list handle 4K at 30Hz using HDMI 1.4, which is fine for spreadsheets and web browsing. If your monitor supports 4K at 60Hz, you’ll need an adapter with HDMI 2.0 support — like the Highwings on this list. For a 1080p secondary display, pretty much any adapter will work, but don’t assume it’ll do 4K just because the box says so.
Unidirectional vs. Bidirectional
All the adapters here are unidirectional, meaning they only convert DisplayPort to HDMI, not the other way around. That’s exactly what you need for a secondary monitor that has an HDMI input. Bidirectional adapters exist but are more expensive and often introduce compatibility issues, so stick with unidirectional unless you have a specific reason not to.
Build Quality and Cable Length
Look for gold-plated connectors, which resist corrosion and provide a more stable signal over time. Braided cables or metal cases add durability, especially if you’re plugging and unplugging frequently. For cable length, measure the distance between your PC and monitor — a 6-foot cable gives you flexibility, while a short dongle around 0.66 feet keeps things tidy but limits placement options.
Compatibility with Your Graphics Card
Most passive DisplayPort to HDMI adapters work with AMD and NVIDIA graphics cards, as well as integrated graphics from Intel. But some older laptops or specific GPU models can be picky. I always recommend checking the product’s Q&A section on Amazon for your exact laptop or desktop model before buying. If you see multiple reports of compatibility issues, move on to another option.
Price and Value Per Adapter
You don’t need to spend a lot to get a reliable adapter. Single adapters are often competitively priced, while multi-packs can bring the per-unit cost way down if you need several. Just don’t sacrifice build quality for the lowest price — a flimsy adapter that fails in a month is no bargain at any price. Focus on products with at least a few hundred reviews and a 4.4-star average or higher.
My Shortcut Advice: If your secondary monitor is 1080p or 1440p, grab the BENFEI adapter — it’s the most proven option on the market. If you need 4K at 60Hz, skip the cheap stuff and go straight for the Highwings.
Frequently Asked Questions
What is the best DisplayPort to HDMI adapter for a secondary monitor?
I’d say the BENFEI 4K DisplayPort to HDMI Adapter is the best overall choice for most people. It has over 65,000 ratings with a 4.5-star average, supports 4K at 30Hz, and works reliably with Lenovo, Dell, and HP laptops. For a secondary monitor used for productivity, it’s the safest bet on the market.
Can I use a DisplayPort to HDMI adapter for 4K at 60Hz?
Yes, but you need an adapter that supports HDMI 2.0, not just HDMI 1.4. The Highwings 4K Display Port to HDMI Adapter is one of the few on this list that delivers 4K at 60Hz. Most budget adapters like the IIABC or KUXIYAN top out at 30Hz, so check the specs before buying.
What’s the difference between passive and active DisplayPort to HDMI adapters?
A passive adapter simply converts the signal without any extra electronics — it’s cheaper, smaller, and works with most modern laptops and desktops. An active adapter has a chip that actively converts the signal, which you’d need for older GPUs or specific multi-monitor setups. For a secondary monitor with HDMI input, a passive adapter like the ones on this list is almost always what you want.
Is a cable or a dongle better for a secondary monitor?
It depends on your setup. A cable like the WARRKY 4K DisplayPort to HDMI Cable gives you 6 feet of reach, which is great if your monitor sits farther away. A dongle like the BENFEI or Moread is more compact and won’t create cable clutter, but it leaves you with a short connection. Measure the distance between your PC and monitor first.
Will a DisplayPort to HDMI adapter work with any graphics card?
Most passive adapters work with AMD, NVIDIA, and Intel integrated graphics, but compatibility isn’t guaranteed for every model. I always check the product’s Q&A section on Amazon for my specific laptop or GPU before ordering. The BENFEI and Highwings adapters have the widest reported compatibility across Dell, HP, and Lenovo systems.
Can I use a DisplayPort to HDMI adapter for gaming on a secondary monitor?
Yes, but you’ll be limited to 4K at 30Hz with most adapters, which isn’t great for fast-paced games. If you want smoother gameplay, go with the Highwings adapter that supports 4K at 60Hz. For competitive gaming, you’d be better off connecting directly with a DisplayPort cable if your monitor supports it.
How many monitors can I connect with a single DisplayPort to HDMI adapter?
One adapter connects one monitor — it’s a direct one-to-one conversion. If you need to connect multiple secondary monitors, you’ll need either a multi-pack like the KUXIYAN 2-Pack or the Mbiydeg 3-Pack, or a DisplayPort splitter that supports multiple outputs. Just remember that each monitor gets its own adapter.
Do I need a gold-plated DisplayPort to HDMI adapter?
Gold-plated connectors help resist corrosion and provide a slightly more stable signal over time, but they’re not strictly necessary for most setups. The BENFEI, IIABC, and KUXIYAN adapters all use gold plating, and I’ve found it makes a difference in humid environments or if you’re plugging and unplugging frequently. For a desk setup that never moves, standard connectors work fine.
My Final Verdict
After testing all nine adapters, the BENFEI 4K DisplayPort to HDMI Adapter is my clear winner. It has the most proven track record with over 65,000 ratings, delivers stable 4K at 30Hz, and works with virtually every laptop I threw at it. The Highwings 4K Display Port to HDMI Adapter is the runner-up if you need 4K at 60Hz, and the WARRKY 4K DisplayPort to HDMI Cable is my pick if you prefer a 6-foot cable over a dongle.
If you’re still on the fence, here’s the simple rule: grab the BENFEI for a no-brainer reliable connection, or the Highwings if your secondary monitor supports HDMI 2.0 and you want smoother motion. Either way, you’ll have your second screen working in under a minute.
