Top 8 Best Monitors for CAD in 2023 – Reviews – 27″, 4K (3840×2160) Options

By | September 4, 2023

If you are operating CAD applications, you need specific kind of monitor that helps improve the cad workflow. Ordinary gaming or standard office monitors are not the best bet for cad applications.

For cad applications there are a number of monitor configurations to choose from, depending on personal taste. Some of the popular ones are:

1. A large 24-27" single monitor. Solidworks do recommend the BenQ 27-32" monitors.
2. A dual monitor setup for more screen space. For example 27"+27" or 24"+24"
3. An ultrawide monitor 2560x1080 / 34" / 21:9 for more space.

Since cad/cam is professional work you will often find yourself interacting with and managing multiple application windows. In which case its better to have an extra monitor or extra screen space to move the other windows aside while you work on the main cad app like solidworks or revit.

Higher resolutions will allow you to get a finer and clearer view of smaller parts in the cad model, however they come at a cost of increased graphical computation. So if you choose a 4k monitor, you will need to pair it with a more powerful gpu as well.

CAD/CAM applications can in general work good enough with 1080p resolution, but if the monitor is large you might want to be able to see the finer details in the models which would require higher resolution. In such cases 1440p or 2160p would be a good choice.

Problems of 4K Resolution

However, at 4K resolutions there are known issues with a lot of applications including Revit, where the user-interface is not able to scale properly, garbling up the display. These problems have been discussed on the forums over here and here.

The primary cause behind such problems is inconsistent dpi scaling across different applications and how microsoft windows handles it.

Other applications like Autodesk Autocad do not really stress much on the specifications of the display monitor, and anything with a resolution of 1080p and capable graphics card is deemed fit enough.

Best Option

Overall the 27" size with a resolution 2560x1440 can be considered a sweet spot. It's the perfect size and resolution for working at a desk. Grab a 3440x1440 ultrawide if you have less desk space, as it is smaller in size overall.

Dual Monitor Setup: Those who want more screen space will prefer a dual or triple monitor setup. First of all a dual monitor setup has a gap in the center if placed symetrically which a lot of users dislike. Whereas a triple monitor setup has 3 cables that need to be connected to the cpu or laptop what it is.

More displays increase the effective pixel count and resolution thereby requiring more graphics processing power. So you also need to invest in a decent dedicated graphics card that can handle this. An RTX 3060 has 3x display ports and can handle resolution upto 7680x4320 which is equivalent of 3x 2560x1400. So for a triple monitor setup this might be the perfect combination is you are ready to spend some good money.

At the current state of market, a dual setup fo 27" 2560x1440 monitors will cost more than a single ultrawide 3440x1440 monitor. However the 27" dual setup will offer signficantly more screen space, slightly better pixel density (108.79 ppi). making it an overall better choice.

If you are short in desk space, then a single ultra-wide is a better option.

Other Technologies:

HDR, OLED, Curved display are certain features that do not matter for cad/cam at all. HDR is for videography and video editing whereas curved display has its own separate audience. If you are looking to save some bucks on your next cad/cam monitor, better look for something that skips these features. Ultrawide monitors are available in flat profiles and would be cheaper than their curved counterparts, which are more useful for gamers and coders.

Freesync/Gsync are another bunch of un-necessary technology for cad/cam applications. Syncing is critical in games where the frames need to display in the right sequence and time without any tear or stutter. CAD/CAM applications do not suffer any such problems neither require any such technological solutions.

Our Top Picks for Best CAD Monitors

Here is our selection of the best monitors for CAD along with their specifications and features. Most of them have a display size of 27" or above and some of them have a resolution of 4K (3840x2160), which is best suitable for CAD work.

1. BenQ PD2700Q 27 inch 1440p IPS Monitor

The BenQ PD2700Q is one of our favorite monitors for running CAD programs for several reasons. It offers a varied selection of image presets and uses in-plane-switching (IPS) technology.

  • Split-screen function
  • Tilt adjustment range -2° to +15°


At 28 inches, the Samsung UE570 is perfectly-sized for a CAD workstation. It’s not too big that it takes up too much space, neither is it too small that you struggle to see the content.

But where this monitor shines is the 4K resolution. If your primary concern when purchasing a CAD monitor is resolution, this model’s 3840 x 2160 pixel is the best. Essentially, this translates to pictures that are bigger, better, and sharper.

The cherry on the cake is the monitor’s capability to support a billion shades of color. This means that not only are the pictures clearer but also vivid and realistic thanks to the improved color accuracy. This is a very welcome feature when you’re dealing with visual-intensive programs like CAD.

The only drawback is that the UE570 has a twisted nematic (TN) display. Now, although this does not offer the best viewing experience - as you’d expect from an IPS display- it’s decent enough for design work. Its horizontal and vertical viewing angles are rated at 170° and 160° respectively. As such, you’ll still be able to view your designs even when you’re observing from the side.

7. LG 29WK600-W 29" UltraWide 21:9 IPS Monitor

If you’re looking to invest in an ultra-wide monitor that will offer a seamless working experience, the LG 29WK600 is your best bet. The 21:9 aspect ratio means the screen doesn’t display the black bars at the top and bottom; hence providing more room to view your design.
