Not exactly the 48'' but I got the 55'' C9 for desktop usage.
It's very nice. The image quality is something else.
The voice control stuff is actually quite nice as well.
The speakers are mediocre, even compared to my lowly 50EUR microlab Solo 6Cs. So just like a monitor.
4K is quite usable...
With the news of 120hz BFI, these are just no-contest, really. If the NVidia Gsync thing last year didn't tip us off, Especially seeing how LG had the 48'' hooked up to a literal gaming rig at CES, it's pretty telling that they're absolutely aware of who's gonna be getting these.
The latter...
Keep in mind, they can't satisfy the TV demand yet, either. I'm still not sure if making these TVs so attractive to monitor enthusisiaists is genuinely two markets starting to overlap or them cheekily testing the waters.
Mobile OLEDs have smear. My note 9 smears worse than VA when at low brightness :/
I understand that this is more of a TFT issue rahter than an OLED issue though.
in terms of competitive advantage over 120/144, it's probably still going to be the case though.
In terms of percieved smoothness, obviously 240 looks better
I'll make the case for waiting until next year to get that HDMI 2.1 spec, unless you're okay with going OLED, which is a whole debate on it's own..
Otherwise yeah, samsung's VRR sets eliminate input lag almost completely with VRR on and have some cool new goodies like FALD/X-Wide Viewing...
The monsters at LG have dropped the 3.5ms MPRT along with 120hz BFI Support >:(
Other than that though, if 4k120 does 7ms lag like 1440p120, then this is next level.
