Detailed Reviews
LG UltraFine 4K — Best Overall iMac Companion
Key Specifications:
- 24-inch 4K IPS display (3840 x 2160)
- 99% sRGB color coverage
- Single USB-C connection with 85W power delivery
- Built-in speakers and webcam
- Height, tilt, and pivot adjustments
The LG UltraFine 4K remains the gold standard for iMac external monitors, and there’s a good reason Apple sells it directly. This monitor was designed in collaboration with Apple, ensuring perfect color matching with your iMac’s display.
The single USB-C connection handles video, data, and power delivery up to 85W — enough to charge a MacBook Pro while connected. The color accuracy is exceptional out of the box, with no calibration needed for most users. The 218 PPI pixel density matches Apple’s Retina standards perfectly.
The integrated 5MP webcam and microphone array make this an excellent choice for video calls, though the camera quality doesn’t quite match the latest iMac’s built-in camera. The speakers are adequate for casual listening but won’t replace dedicated audio equipment.
Dell UltraSharp U2723QE** — Best Value 4K Option
Key Specifications:
- 27-inch 4K IPS display (3840 x 2160)
- 95% DCI-P3 color coverage
- USB-C with 90W power delivery
- Built-in KVM switch and USB hub
- Factory color calibration
Dell’s UltraSharp line has earned respect among professionals, and the U2723QE delivers exceptional value for iMac users. The 27-inch screen provides significantly more workspace than the LG while maintaining sharp text and images.
The monitor comes factory-calibrated with a color accuracy report, ensuring consistent colors right out of the box. The 95% DCI-P3 coverage makes it suitable for photo and video work, though it doesn’t quite reach the LG UltraFine 4K’s color precision.
What sets this monitor apart is its connectivity. The built-in KVM switch lets you seamlessly switch between your iMac and another device, while the USB-C hub provides multiple downstream ports. The 90W power delivery can charge most MacBooks, making cable management simpler.
Samsung M8 — Best Smart Monitor with Built-in Features
Key Specifications:
- 32-inch 4K VA display (3840 x 2160)
- 99% sRGB color coverage
- Smart TV platform with streaming apps
- Magnetic 4K webcam included
- Height and tilt adjustments
The Samsung M8 breaks the mold by functioning as both a premium monitor and smart display. When your iMac is off, you can stream Netflix, browse the web, or video chat using the monitor’s built-in operating system.
The 32-inch screen provides ample workspace, though the VA panel doesn’t match IPS displays for color accuracy and viewing angles. However, the 99% sRGB coverage is sufficient for most productivity tasks and casual photo editing.
The included magnetic webcam is a clever touch, attaching securely to the top of the monitor when needed. The camera quality is decent for video calls, and it stores neatly when not in use. Smart features include AirPlay support, making it easy to mirror or extend your iMac’s display wirelessly.
The glossy screen finish looks premium but can be problematic in bright environments. This monitor works best in controlled lighting conditions.
BenQ SW271C — Best for Creative Professionals
Key Specifications:
- 27-inch 4K IPS display (3840 x 2160)
- 99% Adobe RGB, 95% DCI-P3 coverage
- Hardware calibration support
- USB-C with 85W power delivery
- Dedicated color mode hotkeys
Professional photographers and video editors will appreciate the BenQ SW271C’s exceptional color accuracy and calibration capabilities. This monitor covers 99% of Adobe RGB and 95% of DCI-P3, providing the wide color gamut needed for professional work.
The hardware calibration support sets this monitor apart from consumer options. Using BenQ’s Palette Master Element software with a compatible colorimeter, you can achieve precise color calibration that’s stored in the monitor’s hardware rather than software profiles.
Physical hotkeys on the monitor’s bezel provide quick access to different color modes (sRGB, Adobe RGB, DCI-P3), eliminating the need to dive into menus constantly. The build quality is exceptional, with a sturdy stand and minimal light bleed.
The premium price reflects its professional focus — casual users won’t need this level of color precision, but creative professionals will find it worth the investment.
Apple Studio Display — Best Premium Apple Integration
Key Specifications:
- 27-inch 5K IPS display (5120 x 2880)
- P3 wide color gamut
- 600 nits brightness
- Thunderbolt 3 with 96W power delivery
- 12MP Ultra Wide camera with Center Stage
The Apple Studio Display offers the ultimate iMac companion experience, with a 5K resolution that surpasses standard 4K monitors. The pixel density matches the 24-inch iMac exactly, ensuring consistent text rendering across displays.
Color accuracy is superb, matching your iMac’s display perfectly without calibration. The 600 nits brightness easily handles bright office environments, while the anti-reflective coating minimizes glare without sacrificing image clarity.
The 12MP Ultra Wide camera with Center Stage automatically keeps you centered during video calls, matching the functionality found in newer iMacs. The six-speaker sound system delivers impressive audio quality that rivals dedicated desktop speakers.
The premium price and limited adjustability (tilt-only on the standard stand) make this a luxury purchase. However, users who prioritize seamless Apple integration and don’t mind the cost will find it unmatched.

Buying Guide: What to Look for in an iMac Monitor
Display Technology and Size
IPS panels offer the best color accuracy and viewing angles for iMac users, closely matching your iMac’s display characteristics. VA panels provide deeper blacks but sacrifice color accuracy and viewing angles. Avoid TN panels entirely — they can’t match your iMac’s color quality.
Size matters for productivity. 24-27 inches works well for most users, providing substantial screen real estate without overwhelming smaller desks. Larger 32-inch displays offer more workspace but require sitting further back to view comfortably.
Resolution and Pixel Density
4K (3840 x 2160) is the sweet spot for most iMac users, providing sharp text and images without requiring scaling adjustments in macOS. Higher resolutions like 5K are nice-to-have but dramatically increase cost.
Pay attention to pixel density (PPI). Monitors around 160-220 PPI will look sharp and match your iMac’s Retina display quality. Lower pixel densities may appear pixelated after using a high-resolution iMac display.
Connectivity Options
USB-C with power delivery simplifies cable management and can charge your MacBook when switching between devices. Look for at least 65W power delivery, with 85W+ preferred for MacBook Pro models.
Thunderbolt 3/4 provides maximum bandwidth and daisy-chaining capabilities but costs more than standard USB-C. HDMI and DisplayPort inputs offer flexibility for connecting other devices.
Color Accuracy
Look for monitors covering at least 99% sRGB for general use. Creative professionals should consider displays with 95%+ DCI-P3 or Adobe RGB coverage. Factory calibration reports indicate the manufacturer takes color accuracy seriously.
Avoid monitors without color coverage specifications — they’re likely using cheap panels with poor color reproduction that won’t match your iMac’s display quality.
Build Quality and Adjustability
Sturdy stands with height, tilt, and pivot adjustments improve ergonomics and reduce neck strain during long work sessions. Look for monitors with minimal bezels and quality construction that matches your iMac’s premium aesthetic.
VESA mounting compatibility provides flexibility for desk setups and monitor arms. Check the VESA pattern (usually 100x100mm) if you plan to use an aftermarket stand.
Frequently Asked Questions
Can I use any monitor with my iMac?
Yes, but results vary dramatically. While any monitor with compatible inputs will display an image, color accuracy, scaling, and overall experience depend heavily on the monitor’s quality. Cheap monitors often look washed out or pixelated compared to your iMac’s built-in display.
Do I need a 5K monitor to match my iMac’s display?
Not necessarily. 4K monitors at 27 inches or smaller provide sharp images that look great alongside iMac displays. 5K offers slightly better text clarity but costs significantly more. Most users will be happy with high-quality 4K displays.
Will monitors drain my iMac’s performance?
External monitors do require graphics processing power, but modern iMacs handle multiple displays well. The M1 and M2 iMacs can drive one external 4K display without performance issues. Intel iMacs generally support multiple displays depending on the graphics configuration.
Should I calibrate my external monitor?
Professional-grade monitors often come factory-calibrated and may not need adjustment. Budget monitors usually benefit from calibration using macOS’s built-in Display Calibrator Assistant or dedicated hardware like the X-Rite i1Display Pro for precise color matching.
What’s the best way to connect multiple monitors to an iMac?
USB-C and Thunderbolt provide the cleanest single-cable solution with power delivery. For multiple displays, consider Thunderbolt hubs or docks that can drive several monitors from one connection. Check your iMac’s specifications for maximum supported displays and resolutions.
Do I need special cables for 4K monitors with my iMac?
Most modern iMacs include the necessary cables or adapters for 4K display output. USB-C to USB-C cables work for newer monitors, while older displays may require USB-C to HDMI or DisplayPort adapters. Ensure cables are rated for 4K 60Hz to avoid bandwidth limitations.
Conclusion
The LG UltraFine 4K remains our top choice for most iMac users, offering excellent color matching, simple connectivity, and reliable performance. Its collaboration with Apple shows in the seamless integration and consistent quality.
Budget-conscious users should consider the Dell UltraSharp U2723QE, which delivers professional-grade color accuracy at a more accessible price. The larger screen size and extensive connectivity make it versatile for various workflows.
Creative professionals working with color-critical content will find the BenQ SW271C worth the investment, while those wanting the ultimate Apple experience should consider the Apple Studio Display despite its premium pricing.
Whatever you choose, prioritize color accuracy, build quality, and connectivity that matches your workflow. A good external monitor should enhance your iMac experience, not compromise it.
