Iiyama releases a trio of G-Master FreeSync displays

At least on 1080p yeah you'd think that. Must be AMDs standard for FS or something. Adaptive Sync certainly is capable of going lower.
 
Any LFC enabled FreeSync monitor can go below its rated FreeSync range(To half, so in this case 20 fps) while maintaining FreeSync. I don't believe LFC goes as far as frame tripling(Since below 20fps the input lag and gameplay experience would be fairly grim regardless).
 
No it doesn't. It starts frame doubling. Meaning it displays same frame multiple times to reach a higher framerate. You'll still notice it looks bad. Sure you're displaying the variable framerate but it's not exactly the same thing
 
Still not 30-144.

BenQ's XL2730Z that came out 3+ years ago has a Freesync range of 40-144Hz, You'd think newer monitors would improve on that.

TBH with FreeSync LFC this is a non-issue, G-Sync monitors do the same thing. If the framerate is below the display's minimum each frame will be displayed twice to offer an identical user experience.

The only difference in AMD and Nvidia's implementation is that AMD's is done on the driver side and Nvidia's is thought to be done on the G-Sync module.
 
I see it as a non issue because not all FS displays are LFC compatible and 4k screens with a range of 40-60 is just useless. So I disagree it's a non issue.

That's a different argument; I was talking about 40-144Hz displays. Lowering the minimum doesn't matter in that case, with non-LFC compliant displays the issue is entirely different.

My 4K monitor is a Iiyama G-Master GB2888UHSU with a 40-60Hz VRR window. I agree that this isn't ideal, but it is better than a display with no VRR window. Though another problem with FreeSync at 4K is the fact that AMD doesn't have anything more powerful than the RX Vega 64.

This is why a lot of display makers are focusing their future panel designs on higher refresh rates, as increasing the upper limit for VRR seems easier than decreasing the lower limit (not quite sure why). With VRR coming to HDMI 2.1 this will be a huge factor for future televisions, at least for gamers.
 
Not a different argument. The whole point is NO MONITOR is at 30hz. It should be

Yeah, but by raising the upper limit LFC can eliminate the issues of the lower limit. There must be a technical reason why variable framerates are having trouble with lower framerates.

Even G-Sync displays have the same problem, where framerate doubling, tripling etc is required for lower framerates. Move forward a few years and we will have higher upper limits on most displays and this issue will be gone.

I agree that lowering the minimum will also help solve the problem, but there must be a reason why that hasn't been done yet.

The article linked here predates LFC, so ignore the fact that the FreeSync monitor, in this case, doesn't go under 40.

The best minimum freeSync range that I have seen is 35Hz outside of LFC supported displays.
 
Gsync is already and always has been at 30hz.

It's still a problem. You can make the argument that doubling solves it but it doesn't. Displaying multiple frames only solves the stutter problem. It's still not smooth and can still tell a difference.

It's just annoying it's taking forever for FS which is why I think it's a standard they set.
 
Putting Freesync aside IIyama are very very good monitors. the calibration you get with their menu is second to none I have the B2783QSU but use it with my GTX 1080 no complaints with it at all after 2 years of using it.
 
Frame doubling is used for both FreeSync and G-Sync at below 40Hz with LCD panels(Not always, but most of the time), it is often the only way to do sub-30(And with most panels sub-40) variable refresh rates, an absolute necessity due to the limitations of LCD technology itself. LCDs need to maintain a minimum true refresh rate to avoid blanking(very very few LCD panels can maintain a true freshrate of lower than 30Hz and this generally has to come at the cost of maximum framerate and/or panel latency.

Frame doubling only exists to force the monitor to display the same image a period of time longer than it can naturally "hold" that image without it fading or blacking out. It is technically what happens whenever you run a monitor at a fixed refresh rate(IE without VRR/FS/GS) but have a variable input rate(Any game with V-Sync disabled) or a set rate below the monitors physical refresh rate(IE a 24 FPS film). There is NO perceivable difference between a monitor pushing 30FPS VRR through frame doubling and a monitor pushing 30FPS VRR natively. The end result is exactly the same. If it doesn't feel smooth, it's because the frame rate is low.

To be clear: LFC only exists to solve one issue, which is the only real issue with VRR/G-Sync/FreeSync below 40/30Hz, which is flickering from the screen blacking out due to the panel attempting to display the same image for too long.
