Acer XR382CQK 37.5 INCH Ultrawide Monitor

I really hope the advancement of 34" models aren't left behind in the pursuit for an even bigger display... 37.5/38" 21.9 is just too much imo, even 34" is pushing it for wideness to my eyes...

I don't think that's something we need to worry about too much, While I've yet to confirm it someone replied to my post on the video claiming the Freesync working range is from 48 to 75 hz, The 38" LG also had a similar range so I don't think they've perfected doing this size panel yet, just like they haven't sussed the 144hz 4k panel, so it'll be a few years before this is anything but a niche product.

I must admit that after owning an X34 and now the 38UC99 I have to agree. Hopefully Freesync2 will fix its shortcomings.

I think you'll find it's that particular monitor's Freesync support that is lacking not Freesync itself.
Because Freesync is open source adaptive sync it is up to the monitor manufacturer to use components with good quality Freesync compatability,
After looking across LG's entire Freesync range it seems that they do not use the right panels,
Add to that how at the moment the 38" panels do not seem to be capable of supporting the full Freesync range and a poor experience is to be expected.
I had my heart set on a 29" LG ultrawide before Freesync was a thing and once Freesync was announced I decided to wait for that before buying an ultrawide monitor.
When the first LG Freesync ultrawides appeared I held off because the working range did not go low enough.

Today's LG Freesync monitors are lacking in the two most important ways.
One is how wide the Freesync working range is and the other is supporting LFC (Low framerate compensation).

You bought a monitor with a small working range and no LFC.
In comparison if you had bought the 34" Acer Freesync equivalent to your Acer G-sync monitor you would have got a much better experience with a range that starts at 30 hz and supports LFC.
It seems that the 38" panels are not yet capable of providing the full Freesync experience.

If you scroll down this page and pick the monitor option in the box you'll see the relevant data

This is how the Freesync tech on the LG 38", Acer 38" and Acer 34" compare


This graph shows the important points mentioned.

Range
LFC support?

LG 38"/ ACER 38"/ ACER 34"


52-75/ 48-75/ 30-75
No/ No/ Yes


In my opinion these are the two most important features for Freesync,
It is where G-sync has total control of a G-sync monitor and where Freesync is at the mercy of the monitor manufacturer.
As we can see both the 38" Acer and 38" LG monitor's are in the same boat with a working range which does not go low enough,
That along with having no LFC when the fps in a game drops below the working range is why your Freesync experience is not how you hoped it would be.

Good info, thanks.

Don't get me wrong, in the main it's a fantastic monitor I just wish it was a touch better of a gaming panel. Guess you can't have it all!! :D

(coming from the X34 probably didn't help, excellent for gaming that)

The Freesync Acer XR34 is a great gaming monitor too,


IIRC, the freesync range isn't down to the panel but the scaler used. The gsync module replaces the scaler, which is why gsync monitors only have display port (as well as HDMI with the newer version)

I'm only guessing at why both LG and Acer haven't released 38" models with better ranges, I was only pointing out why the experience of Freesync on such a monitor won't be as good as it could be.
If it's just a scaler and there's no panel limitation in play with these new 38" panels it's odd that Acer out of all of them would now do a top of the range model without the full available range and LFC when they've been doing the best Freesync Ultrawides to date,

I've had a 144hz 2560x1080 VA and a 75hz 3440x1440 IPS from Acer. I've also had a 2560x1440 Asus Dominator, That was a horrible monitor that didn't even run Freesync beyond 90 even though it was a 144hz monitor.
 
The only LG UW with freesync worth considering is the 34" 2560x1080 144hz gaming monitor, it has a very wide range. But yeah the 29" is a 75hz panel with something like 20hz freesync range. So really limited choice. 29" for better sharper PPI and probably best res for the size, only 75hz poor freesync range, but too small vertically. 34" LG 144hz good freesync range but at the size low PPI despite being able to have good FPS

I haven't had a proper look at that one yet, It sounds a lot better than the other models.

Probably down to the price i.e. the better the scaler, the higher the cost will be.

It could be but personally if I'm spending over a grand on monitor I'd prefer to spend an extra few hundred for a decent scaler to get the wider range and the LFC,
From what I read, for a Freesync monitor to support LFC it's minimum working range (hz) needs to be under the maximum working range (hz) when doubled,
LFC's a newish addition to Freesync which work in a similar way to G-sync when framerates drop below 30 fps, It does so by doubling up on the available frames.

If I've got any of this wrong I'd appreciate getting corrected :)
