Hi,

I have just purchased a new monitor, it is generally very nice, but, in a few areas, it is not doing what I expect.

It is an LG 27GS85Q. It's specifications include


Refresh Rate - 180Hz (or 200Hz if overclocked)
Colour Pallette - 10 bit (8bit + FRC)
AMD FreeSync

All sounds great but when I connect it up to my 9060XT using DisplayPort and looking at Windows and the AMD Adrenalin Suite I don't see this

Refresh Rate - the highest option is 144Hz, initially I was using my old DisplayPort cable so I thought that might be the cause, so I swapped it out with the cable that came with the monitor - made no difference.
Colour Pallette - adrenalin reports 8 bit, technically that is correct but I would be more reassured if it reported 10 bit or 8 bit + FRC.
AMD FreeSync - Adrenalin reports that AMD FreeSync is not supported

All this sounds like I have a different monitor than sold, or that LG are fibbing about their specifications, but I doubt that, I imagine there is some configuration/tweaks that I have done and don't know how to do.

Appreciate any advice and assistance to get the monitor working as sold.
 
Is your PC perchance using the old monitor's INF file?

And - hopefully a silly question - but have you set the monitor to 180 Hz?
 
All sorted.

Did a reset of the monitor.

Then turned on overclock and the monitor switched to 200Hz. Checked windows and 180Hz was available so switched to that. Turned off overclock and the 180Hz option remained.

On the monitor, found that adaptive sync was not enabled, when I did this then AMD FreeSync became available, but the refresh rate switched to 144Hz. Turns out that my monitor only has AMD FreeSync Standard which only supports up to 144Hz, if you want to run higher then you need a more expensive monitor with AMD FreeSync Premium or Premium Pro.

Also, I noticed after doing all this that the colour palette was showing 10 bit.

I'll have to decide whether I want AMD FreeSync and run the monitor at 144Hz or turn it off and run at 180Hz.

It was a cheapish monitor, I assume that is pretty standard until you start spending substantially more. Or is AMD FreeSync Premium more common than that. I think of all the monitors I considered, they all just said AMD FreeSync, none said what grade.

Nah, I think LG have just cheaped out on it by the sounds of it.

The competiting Asus monitor (XG27ACS) has FreeSync Premium so you get it all the way from 48hz-180hz - as well as LFC now.

Weird that LG only included standard FreeSync - also weird that standard FreeSync only works to a max of 144hz too. I hadn't even though about that being a thing until I saw this:

 
Who the hell releases a monitor that has a 200Hz refresh rate but doesn't support the VRR tech at that refresh rate? Jesus Christ, LG. I would return this monitor just on principle alone if that's true.

Have you tried contacting LG and confirming the situation? This doesn't seem right to me. Their product page doesn't mention any limitation about this.

Especially because the version before, the GP850, was 165hz (OC to 180hz) and supported VRR all the way up to 180hz!
 
This is the AMD FreeSync specifications from the AMD Website

What's more difficult is knowing what tier of FreeSync the monitor has. I've not seen it specified in any of the monitors that I have looked at.

So much for all these fancy 240Hz monitors - they're all stuck at 200Hz or less if they want to use AMD FreeSync.

I would be more than pleased to know that I am wrong, I'm just going with what I read in that table and what happens on my monitor when I enable FreeSync.

But I do note that the table has a greater or equal sign - but that is odd specifying a maximum value with a minimum.

Actually, I could be telling porkies. I have it turned on now and the refresh rate has stayed at 180Hz.

In my defence, when I did it earlier it did seem to switch to 144Hz, also when I first saw the table above I was looking on my phone and didn't notice the >= signs.

Think it might be okay.
