BenQ PD3420Q

The PD3420Q lands in the 95th percentile for color accuracy with 98% DCI-P3 and 100% sRGB coverage, making it one of the best creative monitors we've tested. The 34-inch ultrawide gives you 33% more workspace than a standard 16:9 panel. Just don't expect gaming performance, the 60Hz refresh rate puts it in the 23rd percentile there.

Let's be honest about what this panel does well and what it doesn't. The color performance is genuinely top-tier. 98% DCI-P3 and 100% sRGB coverage with 10-bit depth means gradients render smoothly and colors look accurate out of the box, especially if you're on a Mac and using BenQ's ICC sync through Display Pilot. That one-second profile sync is a small thing that saves real time if you switch between color spaces regularly. The IPS panel also keeps colors consistent across wide viewing angles, which matters when you're showing work to a client sitting next to you.

The refresh rate is where this thing shows its age. 60Hz and 5ms response time put it near the bottom of our performance charts. For photo editing, illustration, and video work, that's a non-issue. But if you're coming from a 120Hz or 144Hz panel, even moving the cursor around will feel slightly less smooth. The 350-nit peak brightness is fine for a controlled office or studio, but in a bright room with windows, you'll wish for more headroom.

Stacked against the competition, the PD3420Q occupies a very specific lane. The LG UltraGear 45GX950A-B and ASUS ROG Strix XG27AQDMG are gaming-first OLEDs with much higher refresh rates and better HDR, but they're not aimed at color-critical work in the same way. The MSI MAG 271QPX and Samsung Odyssey G60SD are also fast OLEDs that will crush this BenQ in motion clarity and contrast. Where the PD3420Q wins is color accuracy and the ultrawide form factor for productivity. If you need a monitor for editing, design, or coding, the BenQ makes a stronger case. If you want to game, any of those competitors will run circles around it.

Pricing is all over the place right now. We're seeing this monitor listed between $600 and $834 depending on the vendor, which is a $234 spread. At the low end, especially if you can find a refurbished unit, the PD3420Q starts to make a lot of sense for a color-accurate ultrawide. At the high end, you're getting into territory where you could start looking at newer panels with better HDR or higher refresh rates. If you're buying, shop around. The refurbished route through Memory Express is worth a look if you're comfortable with that.

The BenQ PD3420Q is a color-first ultrawide that lands in the 95th percentile for color accuracy in our database. That's the headline here. You're getting 98% DCI-P3 coverage, 100% sRGB, and true 10-bit color on a 34-inch IPS panel, which puts it ahead of nearly everything we've tested for creative work. The 3440 x 1440 resolution gives you 33% more horizontal room than a standard 16:9 display, and for video editors or designers juggling timelines and toolbars, that extra space is genuinely useful.

But this is not a gaming monitor, and the numbers make that clear. It's locked at 60Hz with a 5ms response time, which lands it in the 23rd percentile for performance. If you're editing photos or grading footage, that's fine. If you're trying to play anything faster than a turn-based strategy game, you'll feel the ceiling. The 350-nit brightness and DisplayHDR 400 rating are also pretty modest, so don't expect HDR to knock your socks off.

Gamers should look elsewhere, full stop. The 60Hz refresh rate and 5ms response time put this monitor in the 23rd percentile for performance, which means anything fast-paced will feel sluggish and blurry compared to even budget gaming monitors. If you want HDR, the 350-nit brightness and DisplayHDR 400 certification are also weak points. This is a color-accurate workhorse, not an entertainment display. If your workflow doesn't involve color-critical work, you're paying a premium for capabilities you won't use.

The BenQ PD3420Q is a purpose-built tool for creative professionals, and it nails that job. The color accuracy is among the best we've measured, the ultrawide aspect ratio is a genuine productivity boost, and the USB-C connectivity with KVM support makes it easy to integrate into a Mac or PC setup. The 60Hz refresh rate and weak HDR are real limitations, but they only matter if you're trying to use this monitor for something it wasn't designed to do. If you're editing video, retouching photos, or designing layouts, this is one of the best color-focused ultrawides you can buy right now, especially if you find it at the lower end of that price range.
