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-percent 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 the monitor is receiving a video signal. 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 actually appears 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.
Here’s the screen draw result.
Playing games on a giant screen is undeniably cool. But if you demand the highest speed from your rig, the V801 is not quite fast enough. It measures about the same as the other IPS-based monitors we've tested. Though it's probably not quick enough for the most competitive gamers, the panel does a good job of keeping motion blur and smearing to a minimum.
Here are the lag results.
We expected the Pioneer to do better in the input lag test, but it only scored slightly better than the rest of the pack (except for Asus' 144 Hz screen, of course). The V801 was a little below average compared to other IPS desktop monitors. We did play a few console games on it using an Xbox 360. Since its output is limited to 60 Hz, we had no trouble keeping up in fast-paced shooters and first-person titles.
