Do backlight strobing/scanning features like 'LED Motion Plus' affect meter profiles? - Page 3 - AVS Forum

Yes. LightBoost. See above post.

And to lesser extent, Sony's new interpolation-free "Motionflow Impulse". This works great for 60fps material -- computer graphics & console games & sports motion on TV. The Sony Motionflow Impulse is a strobe backlight on Sony that outperforms scanning backlights. It comes very close too without needing to use interpolation, but it has dimness/flicker disadvantage. Do not forget to disable the ambient light sensor because it can excessively dim the image -- Motionflow Impulse becomes too dim when the ambient light sensor is enabled. Sony HDTV's in the series HX920, HX923, HX925, HX929, XBR950, W905A, W802A all now has this interpolation-free plasma-competing strobe mode, which shines during HTPC 60fps video game.

However, LightBoost is still the world's LCD motion clarity champion but is currently limited to computer usage.

Hey Mark, Today I received the 4H Ultra HD Sony 55X9005 here smile.gif

I have already performed a lot of motion resolution tests using reference 1080p Blu-Ray Disks, With Impulse Mode Enabled, the motion resolution is clearer vs any other LED/LCD I have ever seen, and it's better from LG 1080p Plasma which I did direct comparison becasue i have a media streamer here with 5 HDMI Outputs.

The negative thing I noticed is that the Impulse mode leaves one long trail, (no multiple trails) one trail at a long distance from the moving object, but the resolution of the object remain superior and very accurate at motion - no details loss. It's like you see a copy of the original image with ~20% opacity, far from the original object....the distance maybe is 3cm long from 1.5m viewing distance.

I will perform a lot of new test soon.

As for Static Resolution Performance using 1080p Patterns, it's failed to reproduce any 1-Pixel White or Black Checkboard, with various background colors, Like AVSHD Sharpness Pattern or my Disk's Advanced Sharpeness Pattern:



I believe that is an upscalling problem, but soon i will try to upscale the image from a 2160p Blu-Ray Player, bypassing the internal upscalling...



In a few days I will have the Samsung 4K Ultra HD here to do direct comparisons.

So, are you an early adopter for 4K displays or is this more of a review/evaluation?

Sony UltraHD arrived to my workplace and I will have it here for months, we can't sell it, it's a display model. wink.gif

Early next month I will have the Samsung UltraHD Model also there.

For the history, I'm working to a company which is distributor here of some Hi-End Audio Companies but we have a separate place with Video Division with almost 80 different TV's, which I have access to them daily. wink.gif

cool, that explains how you have access to such a wide range of displays... have you seen any OLED displays up close yet?
