Pros / The touchscreen on this monitor uses edge-lit LED lighting and a projected capacitive technology. You can touch the screen in 20 places at the same time and receive a response for each touch. Additionally, you can recline the screen to 15 degrees or rest it flat on a table.

Cons / This touchscreen monitor isn't meant for high-end gaming, so if you were to use it for that purpose, you would notice the slower response time of 12 milliseconds.

 Verdict / This touchscreen computer monitor has a nice picture and a sleek design. The screen is made to adjust to your arm so that you can comfortably use it and still have a great view with the wide viewing angles.

While touchscreen monitors have nifty features, they are generally uncomfortable to use. The Planar Helium PCT2485 gets closer to solving this problem than most other touchscreens. Its large, almost 24-inch display and touch-enabled screen make it a little easier to navigate through desktop programs, and its slim design makes it more attractive than a lot of the other available models.

Touchscreen Performance

The Planar Helium PCT2485 has a tilt range of about 55 degrees, which is slightly wider than our top pick's, the Acer T232HL, but Planar's monitor is also slightly thicker and heavier. The display surface is edge-to-edge glass, and the rim of this large touchscreen display is reminiscent of a tablet. 

The wide bezels lift the display off your desk, though not quite as high as other models. Still, it’s high enough that it’s easy to find a place to comfortably rest your hands, which is a problem with some of the other touchscreen monitors we reviewed.  The Planar comes with a U-shape stand that pops up. When it’s down, the monitor lies flat on your work surface, which is a nice feature.  


The Planar PCT2485 has the same seamless bezel design as the Acer model we reviewed, but its OSD surface touch controls are in the bottom right corner. We gave preference to monitors that house the OSD controls away from the touch surface because bumping the buttons and triggering the display control menu interrupts workflow. While there’s an option to lock these buttons on most devices, more thoughtful designs had them in a more convenient location on the touchscreen.

This is the only multi-touch monitor in our review that has a webcam. Interestingly, this makes it feel even more like a giant tablet, though the camera captures images at odd angles because the monitor reclines.

This touchscreen display uses more energy on average than others in our comparison. Its large screen is likely the reason why, but our top pick is almost as big and only uses 20.9 watts compared to the Planar Helium’s 35 watts. Overtime, it might be a little more expensive to run than other monitors in our review.


We’ve already pointed out that this 1080p touchscreen’s size is impressive, but it’s worth mentioning how immense it looks on a desk compared to other touch monitors. Planar makes a version of this monitor with all the same features and a viewable screen size of just under 27 inches.

One of the features that’s a bit of a letdown is the Planar PCT2485’s slow response time of about 14 milliseconds. The response time measures how quickly individual pixels change from light to dark or from gray to gray, which impacts colors and images on the screen. Monitors with longer response times might have noticeable ghosting – the after effects of the pixels taking too long change, which causes images from previous frames to linger.

It’s a problem that you might not notice unless you use the monitor for high-end gaming or watching fast-paced action movies, but 14 milliseconds is really slow by today’s standards. Most monitor’s response times are under 10 milliseconds, and some are even as low as one millisecond.

The pixel pitch, or the distance between individual pixels, is slightly larger too. Because of this, the image isn’t as sharp as on other monitors we reviewed.


The ports sit close to the bottom of the monitor, which can put pressure on the cables and can make port adapters difficult to use. Still, the U-shape stand does make them easier to access than some of the solid stands we saw.

This monitor has both a DisplayPort and an HMDI connection – an improvement over the Acer with its single digital-audio port. Unfortunately, Planar still uses USB 2.0 ports, so the data transfer rate is significantly slower than monitors with USB 3.0 connections. 

Help & Support

Planar has a three-year warranty and a great support system, which includes email, live chat, downloadable documents and a phone number. You can’t reach the company 24 hours a day, but its representatives are very responsive and knowledgeable about its products. We had some of our best customer service interactions with Planar’s team.


Though it’s a sort of hybrid between the two, a touchscreen monitor should be designed and used differently than either a tablet or a regular desktop monitor. The large and slim Planar Helium PCT2485 looks and feels just like a large tablet fitted with an A-frame stand. Even though its tablet-like design doesn’t solve every problem, this monitor is still much more functional than the touchscreens that look like old-fashioned upright monitors, which consequently have limited range and flexibility. It’s just not quite as imaginative or forward-thinking as our number one pick. Even so, there are a lot of reasons to consider the Planar PCT2485, including its high quality and interesting touchscreen design.
