What causes motion blur/juddering on PC monitors?

[zeock9]

It drives me crazy to see fast moving objects in videos appear blurry on my PC monitor,
so what exactly causes such motion blur during video playbacks or on Youtube clips?

And which spec. do I need to pay special attention to to minimize such motion blur and juddering while watching video on my PC, higher refresh rates? or lower GtG response time?

thanks

"Juddering" is generally from low framerates. Most videos are recorded at ~24fps, and motion blur is added to help with the juddering. In Asia, most TV is recorded at 50-60fps so you don't get that, but it's American tradition that 24fps looks "cinematic" and 60fps looks "cheap".

Motion blur is when your monitor can not change color fast enough(response time). Juddering and tearing is when your gpu output is out of sync with your refresh rate.All 3 of the things you mention are important to a smooth gaming experience. GtG response is a marketing term, what counts more is dark to light and color to color. You'll see some monitors advertise a low gray to gray response but are horrible in actual real world scenarios.
Post your specs including monitor and we'll tray and help. But really you need all 3, higher framerates, lower response and synced output to enjoy a better view.

Motion blue from the monitor, and motion blur in a recorded video are two very different things with different causes.

Depends what kind of monitor you use. If you are using an HDTV they often have software that tries to make up for missing frames or a frame rate that is too high for the incoming video. Frame rates on some video is only 30 frames a second, but your video may be capable of 60, 120, 240 or higher. This can cause rough looking video. However, you may consider turning down the correction that your HDTV is doing.

Often I have noticed when the video is starting to do this, often there is a Windows 10 update that is downloading. Microsoft is too stupid and allows this update downloading during prime time when people come home from work and try to watch video.

I'm thinking about getting Acer XF270HU model which has a 144hz refresh rate but slower than my current monitor's response time of 4ms due to it being an IPS panel,
so I'm wondering if its 4ms response time could cause blurring or ghosting effects on fast moving objects during video playbacks or gaming, in which case I'd choose the 1ms TN panel variant.

thanks again

What is your gpu/cpu combo?

 

[Yuriman]

The advertised response times are mostly nonsense. You can't trust them. Most screens have a real response time in the range of 14-35ms, despite claims of 1-2ms.

I have haswell-e i7 K on the X99 mobo and a GTX970
