HGFRTEE Portable Monitor vs SIBOLAN 15.6: A Real Comparison

The 5 inches of screen is the whole story here. One of these fits in a backpack pocket and runs off a single USB-C cable; the other is a real second monitor you'll actually want to work on.

I bought the little HGFRTEE first for a work trip, then grabbed the SIBOLAN a few months later when the small one started feeling cramped. Both have lived on my desk and in my bag, so here's how they actually shook out.

Where the HGFRTEE wins

Size and weight, full stop. This thing disappears into the front pocket of my backpack next to a notebook, and I genuinely forget it's there until I need it. On a four-day trip to my sister's place over the holidays, I propped it next to my laptop on her tiny guest-room desk and ran my Slack and email on it while I worked on the main screen. There wasn't room for anything bigger — the desk was maybe 24 inches wide and shared with a lamp. The 10.5-inch panel also sips power, so on the train ride down I ran it off a battery pack that was already charging my phone, and neither device complained. For a Raspberry Pi setup, a camera field monitor, or a glanceable second screen for chat apps, the small size is the entire point. At $38.59 it's cheap enough that I didn't baby it, which is half the reason I actually brought it places. The expensive gear stays home.

Where the SIBOLAN wins

You can do real work on it. The 15.6-inch panel is close enough to a normal laptop screen that I stopped thinking of it as an "accessory" and started treating it as my actual second display. I edited a spreadsheet across both screens for an afternoon and never felt like I was squinting, which is something the small one can't claim — anything dense like a spreadsheet or a code editor gets uncomfortable on 10.5 inches fast. It's also the better gaming screen by a wide margin. I plugged a Switch into it on the couch and the bigger panel made handheld games feel like a proper TV session, where the small monitor felt like I'd just zoomed out. Colors looked richer too, though I'll admit I didn't measure anything, I just noticed games and video looked less washed out. If this is going to be a screen you stare at for hours, the extra five inches matters more than the price gap suggests.

The honest differences

• The SIBOLAN is a better monitor, but the HGFRTEE is the one I actually pack — and a screen you bring beats a screen you leave at home.
• The small one runs off a single cable and a phone battery; the SIBOLAN wanted its own power brick when I pushed brightness up, so "one cable" turned into two on my desk more often than I expected.
• Text is sharper on the SIBOLAN because the pixels are spread across a sane size, while the HGFRTEE's higher-density spec sounds nice but cramps everything into a space too small to enjoy it.
• For gaming the SIBOLAN wins easily, but the HGFRTEE survived being tossed in a bag with zero protection three trips running, and I'd never do that with the bigger one.
• The price difference is about nineteen bucks, which is less than I expected for five extra inches — though once you factor in the bigger one occasionally needing a power adapter, the "cheap" gap closes a little.

Which one I'd buy

The SIBOLAN, if I could only keep one. It does everything the small monitor does and adds the one thing the HGFRTEE can't fake: enough screen to work and play on without your eyes filing a complaint. The roughly twenty-dollar premium is nothing compared to how often I reached for the bigger one once both were on my desk. I've left the HGFRTEE in a drawer for weeks at a stretch.

But I get why someone picks the other way. If your whole reason for buying is "I want a second screen that vanishes into a bag," the HGFRTEE wins on that single trait and nothing the SIBOLAN does changes it. People doing camera work, Pi projects, or constant travel on cramped tables will be happier with the little one — it's the difference between a tool you carry and a tool you have to plan around. My buddy who shoots video grabbed the HGFRTEE on my recommendation specifically because it clamps onto his rig without throwing off the balance, and a 15.6-inch panel would've been useless to him.

So: SIBOLAN for a desk and a couch, HGFRTEE for a bag and a job site. I bought both and don't regret either, but if you forced the choice, the bigger screen is the one I'd hand to most people.

One last thing worth saying — both of these have been reliable for me, no dead pixels, no flicker, no weird port issues, which I half-expected at these prices. Cheap portable monitors used to be a gamble. These two weren't. The decision really does come down to those five inches and where you plan to put them, so figure out whether you're buying a travel screen or a work screen before you spend a dollar. Get that part right and either one will treat you fine.
