GeChic On-Lap 2501M 15.6" Battery-Powered Monitor, Tested

Features
By published

Do you ever wish you could watch video on something larger than a smartphone when you're on the road? GeChic thinks it has an answer with the On-Lap 2501M portable monitor. We benchmark the display to see if its performance matches its convenience.

Results: Pixel Response And Input Lag

Pixel Response And Input Lag

To perform these tests, we use a high-speed camera that shoots at 1,000 frames per second. Analyzing the video frame-by-frame allows us to observe the exact time it takes to go from a zero-percent signal to a 100% white field.

The pattern generator is placed at the base of the monitor so that our camera can capture the precise moment its front-panel LED lights up, indicating that a video signal is being received. With this camera placement, we can easily see how long it takes to fully display a pattern after pressing the button on the generator’s remote. This testing methodology allows for accurate and repeatable results when comparing panels.

We’ve returned the data from our past TN-based monitor reviews to the charts so that comparisons can be made between IPS and TN technology.

The On-Lap is slower than other TN monitors in the response time test. It’s also takes a hair longer to draw a full-white screen than the 27-inch IPS panels we’ve recently tested. Let’s see how the overall input lag affects the numbers.

The On-Lap is still at the back of the pack for absolute input lag. This is not a screen for hair-trigger gamers with Jedi-like reflexes. It’s certainly fine for slower-paced mainstream games, though. With two HDMI inputs, you can hook up a laptop or even a console to it for a truly portable gaming experience.

    So even though the hardware itself is excellent, the final product is too niche-y to sell ?

    A portable monitor at the conveniently low price of an entry level tablet or chromebook... I see real utility here.

    It is an industry artificial block in my opinion. All they would have to do is include a little extra circuitry to the existing pads for an HDMI input and viola, you could use your pad as a monitor to another device. Most pads have at least that resolution on some even better. I would never buy this item unless it was under $150 or less. It is a one trick pony with a low resolution screen.

    I'd love to have one of these portable monitors. I've go a bunch of headless PC's that I need to check every once in a while and don't want to lug a regular monitor around nor hunt for a power socket for the test monitor. If only the price were a little lower...

It may only have a niche use, but it is clearly better suited for that niche use than a tablet screen would be.

    Senor Kalyanhttp://us.aoc.com/monitor_displays/e2251fwuNice product, except it doesn't have its own power supply and can only take a USB signal over a DisplayLink driver. Makes for a nice quasi-mobile secondary monitor for computers, but it won't connect to most types of mobile devices like the GeChic will.
