Got it set up and comparing to my un40h5500.
Definitely VA, blacks are inline with the Samsung.
Input lag is awful if you don't use the game preset. And when you do, you only get basic picture settings. No 2pt and 20pt white balance, just a warm to cool color temp slider. Color settings get swapped for a +/-5 pt setting for sky, grass, and facial colors.
Red is a little off in this setting, leaning towards a dark orange. Green is green, but much darker green then the Samsung. Blue seems like it needs a few points of red added. With the limited options in this setting, there isn't a way to fix it.
There is a lot less ghosting/smearing then the Samsung, but not as good as some other sets I've tried recently (H6350, H7150, Visio P series). The h5500 is just really bad when it comes to this.
The pointer on the remote works well, first pointer remote I've tried this accurate. The one on the new UN65JU750D is far slower and less responsive. However, using the remote to adjust settings seems to be enough to bog the system down at times. Had it lock up twice, needing to be turned off and back on again.
Also have a pixel just right of center stuck on green.
Looks like my search for a new game TV continues.
