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

Measurement And Calibration Methodology

To measure and calibrate monitors, we use an i1Pro spectrophotometer and the latest version of SpectraCal CalMAN software (v5.0.3).

For patterns, we employ an AccuPel DVG-5000 video signal generator. This approach removes video cards and drivers from the signal chain, allowing the display to receive true reference patterns. Connections are made via HDMI.

The AccuPel DVG-5000 is capable of generating all types of video signals at any resolution and refresh rate up to 1920x1080 at 60 Hz. It can also display motion patterns to evaluate a monitor's video processing capabilities, with 3D patterns available in every format. This allows us to measure color and grayscale performance, crosstalk, and ghosting in 3D content via the 3D glasses.

We realize that the On-Lap 2501M will not be calibrated by its typical user. This is, after all, a convenience product, not a performance-oriented one. Still, we feel it’s relevant to run any display through our battery of tests so that you know what image quality to expect. Except for gamma control, the On-Lap has the same calibration adjustments available on a desktop monitor. There are no picture modes, so you can’t toggle between different settings combos. The table below holds the settings that we used in our tests.

    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.
