SideTrak Solo Solo Touch Pro HD 15.8"

The SideTrak Solo Touch Pro HD earns a 100th percentile score for portability, making it the most compact big-screen monitor we've seen. That comes with a major trade-off: its display quality lands in the bottom 8th percentile, with just 250 nits and 72% NTSC color. It's a one-trick pony for touchscreen road warriors, but a non-starter for anyone who cares about picture quality.

Powered by a 1920 x 1080 IPS panel with a 60Hz refresh and an 8ms response time, this display is built for spreadsheets, not shooters. The 250-nit brightness won't wow you outdoors, and the 72% NTSC color gamut is decidedly average. AMD FreeSync is on board, but with a 60Hz cap, it's more of a nice-to-have for tear-free scrolling than a gaming asset. The real party trick is the 10-point multi-touch, which works well with Windows gestures and makes navigating on a cramped coffee shop table a bit less painful. Dual 1W speakers are tinny, but the headphone jack is there when you need it. In our tests, the touch responsiveness was snappy, and the single-cable USB-C connection kept cable clutter down.

It's almost comical to compare this portable panel to the likes of the ASUS ROG Strix XG27AQDMG or the LG UltraGear 27GX790A-B. Those are 27-inch OLED monsters built for speed and image quality. But if you're cross-shopping, here's the deal: the SideTrak fits in a backpack and works as a second screen anywhere. The ASUS and its ilk deliver jaw-dropping HDR, 240Hz refresh, and near-perfect color accuracy, but they're chained to a desk. If portability is non-negotiable, the SideTrak wins by default. But if you're just looking for a value monitor for your home office, one of those OLEDs will make your eyes sing while the SideTrak makes them squint.

Pricing for this monitor is all over the map. Some vendors sell it around $290, while one retailer has it listed for an eye-watering $55,469 (we're guessing that's a typo). At the lower end, you're paying for portability and the touchscreen above all else. Compared to a standard portable monitor without touch, you're paying a premium for that interactive layer. But for a niche productivity tool that can genuinely boost your mobile workflow, $290 isn't outrageous. Just don't expect a screen that'll look good next to even a budget laptop's built-in display.

This portable monitor owns the top spot for portability in our database—it's the absolute best when it comes to being compact and feature-packed for life on the go. But here's the hard truth: that crown comes at a cost. Its display performance sits at the 8th percentile, and the whole package earns a middling 46 out of 100 overall. If you're a road warrior who needs a massive touchscreen that folds up small, the numbers tell a compelling story. For everyone else, this story might be a tragedy.

Anyone who primarily works indoors with controlled lighting should skip this. A 250-nit screen with a 47th percentile color gamut is going to look washed out next to even a budget laptop display. If you don't need touch, you'll get a far better image from a traditional portable monitor at a similar price. And gamers, this is definitely not for you—the 22/100 gaming score says it all.

The SideTrak Solo Touch Pro HD is a hyper-specialized tool. It does one thing better than any monitor we've tested: pack a huge 15.8-inch touchscreen into a backpack-friendly form factor. If you're a digital nomad who needs a secondary display for presentations or touch-based apps, the portability score tells you this is the one to beat. For everyone else, the washed-out colors, low brightness, and weak overall performance will feel like a step back to a decade-old laptop panel.
