Not all FreeSync monitors support LFC. FreeSync 2 certification makes LFC mandatory.
yes, but mandatory lfc alone is rather flimsy bonus for new version of freesync. as long as you keep an eye out for lfc support you'd probably get much better deals for old freesync monitors once new ones are out
The film he described in the video is real. It is caused by dynamic contrast ratio because the pixels let too much light from the backlighting bleed through. It's pretty obvious on virtually any movie: look at the letterboxing area at the top and bottom and note how it is gray, not black. That's a limitation of non-HDR panels.
non-black blacks like in that letterboxing is a limitation of lcd panels and has nothing to do with hdr.
not the point here but dynamic contrast ratio as such is evil and should burn in hell.
btw, hdr will make this even worse. the drive is towards larger contrast ratios and brightness is the easy way to go with lcd, black levels be damned.
The reason why FreeSync 2 certification is great is because even though a panel can accept 10-bit color and HDR data doesn't mean it actually produces it visually. FreeSync 2 certifies that not only do they accept the signal, they faithfully produce it.
amd has not said this.
well, in a typical amd fashion, there are very few real details available. wording in their presentation is very carefully about hdr support. support, not requirement.
if the standard really will require 10-bit, hdr and 2.5x min/max refresh rate, the monitors are going to be
VERY expensive. both models
And yeah, there are definitely standardization issues. The fact LFC isn't part of the VESA adapative sync standard is a problem. DisplayPort should also have HDR capability flags so that the graphics card can signal whether SDR or HDR content is in the tube so the display can adjust accordingly.
end-to-end 10-bit from pc to screen is problematic today. this, when not even looking at hdr.
latest displayport versions already have some hdr metadata in the standard and the data stream itself is just 10-bit data so nothing complicated about the data transfer.
processing the hdr data at both ends is going to be interesting for a while though.
i think lfc is beyond what displayport standard is supposed to handle. displayport is about transferring the data, after all. doubling the frames is implementation question for data processors at either end. currently gsync is doing that in hardware in the monitor, lfc seems to be doing that in software on pc.
