AOC E1659FWU And GeChic On-Lap 1502I: Portable Monitors, To Go
AOC and GeChic recently introduced a pair of portable, USB-powered displays. GeChic’s On-Lap 1502I boasts a 1920x1080 resolution and 10-point multi-touch. AOC’s E1659FWU delivers simplicity and a low price. We compare their display performance today.
Results: Pixel Response And Input Lag
To perform these tests, we use a high-speed camera that shoots at 1000 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 our camera can capture the precise moment its front-panel LED lights up, indicating that a video signal is being received by the monitor. 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.
Here’s a shot of our test setup. Click on the photo to enlarge.
The brighter section of the camera’s screen is what will actually appear in the video. You can see the lights of the pattern generator in the bottom of the viewfinder. We flash the pattern on and off five times and average the results.
Unfortunately, we weren’t able to connect AOC's E1659FWU to our pattern generator for this test, so we’re only able to show results for GeChic's On-Lap 1502I.
The On-Lap’s screen draw performance matches that of other IPS panels we’ve tested. Our historical data shows clearly that resolution and screen size do not affect the results. All the IPS monitors we’ve tested this year complete a full black to white transition in 20 to 24 milliseconds.
Next up are the lag measurements.

There are no major differences here either. All of the IPS monitors we’ve measured refresh at 60 Hz, and they all exhibit input lag between 52 and 94 milliseconds. It seems the only way to significantly improve this metric is to increase the refresh rate.

g-unit1111 Interesting, I'm interested in getting one of the USB displays but the resolution is keeping me from purchasing one. I'd like to see how the AOC monitor compares to the ones being offered from Asus, HP, Dell, and so on and so forth.Reply -
mathew7 So....I am looking for a few years for a small (15" would be limit) portable VGA+HDMI monitor (as in not a bulky stand). I don't need FullHD resolution, but it should accept it.Reply
In a related note, I have been thinking about a laptop-styled monitor+keyboard (and maybe mouse/touchpad) but to be plugged into a desktop PC. You know...when you receive a PC case (or go to someone) and have to debug it. But again, 15" is already big (I'm using a 12.5" thinkpad when not at my gaming/workstation PC). -
ceberle You can connect the On-Lap to a phone or tablet via its HDMI/MHL port. The AOC will only work via USB.Reply

One of the most funded projects on kickstarter. These guys make portable monitors that are HD and really cheap. Unfortunately, they still have their flaws (the circuit board is exposed and not attached to the screen) but you cannot beat the price/performance. -

I have to say after reading about these that I do want one. When my laptop's primary display is 1920 x 1080, why would I want to add a second monitor that's 1366 x 720? -

I'm sorry, I mistyped. The monitor is actually a FHD (1080p) display, and it comes in 15.6 and 17 inch screens. I hope this helps. I'm ordering mine soon to use with a LAN box.
