55 inch tcl 6 has that weird cross-hatch pixels that looks a bit worse specially as a monitor. Vizio also has them. Get a 65 inch from both companies to get proper pixels.

Got cheap TCL 4 and there's an inherent low level of soap opera effect or quite some motion smearing that can't be turned off. Gamma shift and viewing angles quite took a hit. Our 8 year old IPS 1080p tv was superior other than size and deeper blacks.

Lower end Samsungs also have judder problems from 60hz if you're sensitive to that though I'm guessing you can force a PC to output 24p if needed.

That being said, check for deals now until new sets come in anywhere from march to july to possibly see clearance prices of 2018 tvs.

Be careful with Samsungs and check first if you can completely disable GLOBAL DIMMING. There's no consensus if fluctuating brightness depending on scene can truly be rid-off unless you start digging into service menus.

Google nu8000 and q6fn subtitle problems, see if that'll be an issue as well.

If one is anal retentive, maybe get a set with no local dimming or at least not a Samsung that can give you a hard time of completely turning of local and global dimming (2 different can of worms). Sony, Vizio, allows you to completely turn it off and no global dimming problems on their P series and X900F but best ask in av forums or check rtings to be sure.

RTINGS isn't perfect to do cross-references on owner forums and other reviews.
I actually have two 4k Samsung tvs. One is two years older than the other. The older one does have a little bit of ghosting with high contrast situations but the newer one is great. It doesn't have any of the issue you mentioned to any degree that I notice.

I know there is a lot of research of Gallium Nitride transistors as an actual replacement for silicon, so if they are set to replace silicon then couldnt the GaN LEDs used by Samsung MicroLED be manufactured and processed differently?
Nope. GaN is specifically for blue, but all of them are still semiconductor devices produced using semiconductor fab plants. They all start with silicon and grow from there.

Even quantum dots are still semiconductor fabbed, it's just trickery with the dopants and layout during deposition.

Even if you could make large-scale diodes using other techniques, you'd still need traditional fab plants like TSMC or Intel have in order to do micron-level pixels.

Good that you don't notice and don't even bother trying to look for it hard enough. Not worth it.

What models did you get?

It's gonna be my major warning for those sensitive to brightness fluctuations such as plasma/oled ABLs.

Don't check these vids as you're already an owner, these are for others I'm warning about samsungs specially edge lit or any edge lit for that matter (except X930E/940E legendary edge lit performers).
