That is important if you're willing to use this TV for 4K@120Hz content.
It's also kinda important if you're planning on using it with 4K@60Hz+HDR content.
VRR requires 120Hz support to work correctly. It's not just for 120 FPS games.
Typical televisions have a minimum refresh rate of 40Hz or 48Hz.
A range of at least 2.5× is required to use Low Framerate Compensation and stay active at frame rates below the minimum supported refresh rate.
- 40–60 Hz VRR = 40–60 FPS range.
- 48–120 Hz VRR = 0–120 FPS range via LFC.
This is because LFC can display 47 FPS at 94 Hz, 46 FPS at 92 Hz, and so on, with the second display.
Well until that patch for the x900h that is
The X900H does not compete with the C9/CX OLEDs. It is a mid-range TV not high-end.
It's not a bad TV at all, but in some regions the price is almost the same as OLED for the 55"/65" models. I can actually get a B9 OLED for less than the X900H where I am.
The C9 can decode DTS internally and has some higher bandwidth hdmi sockets which allow it to handle content beyond what it can otherwise actually display. The Cx appears to hold back a little on brightness too, so it's likely to be less prone to burn in.
So not a great deal.
- The CX has double the motion resolution of the C9 when BFI is enabled at its maximum setting in 60Hz.
- BFI is supported at 120Hz on the CX and not at all on the C9.
- The CX also has smoother gradation near black.
Note that enabling BFI will reduce the brightness and cause the image to flicker - that's just how it works.
Unfortunately LG's implementation of BFI at 60Hz is limited, so only the highest setting is useful - and that one cuts out the most light.
With a better implementation the low/medium settings could also have been useful (refreshing at 60Hz rather than 120Hz) but with more light output.
B9 has lower quality image processing - mainly seen as worse gradation near black compared to the C9.
But it's still an OLED, and is still going to beat something like the X900H.
I love my C9 but do wish it was brighter and I find it has a tinge of blurriness but that could be the content. Sometimes I'll spot an LED at work or in a showroom and I can more easily point out some small details in the picture.
OLEDs have the highest pixel-level contrast of any display. If the image is sharper on something else, it's probably image sharpening processing being applied by the TV rather than the display panel.
i play at my desk, but mount my tvs to the wall so they are about 3-4 ft away. ideally want a 40inch max. whats my best option?
There was some discussion here recently:
I’ll be sitting quite close to the screen so I don’t need anything bigger than 32” as it’ll just be too big for the distance I’ll be sat just about 3-4 feet away. I want a decent screen that will be hdr, 4k, low input latency, OLED and maybe (but not essential) hdmi 2.1 what are my options?

The short answer is that there's nothing really good until you get to the 48" CX OLED.
48" at a desk is difficult, but it's possible to make it work if you do things like getting a keyboard tray/arm to push things back another foot, and a chair which is made to be ergonomic while reclining.
