I didn't try going lower as this suits my needs well. With this on, I can't think of going back to freesync less gaming anytime soon. This is a completely different experience and one that you have to have yourself. No one can describe. Such are the experiences when your eyes are tricked. Think of magic tricks! wink.gif

I don't think I even need 40-75, just 55 seem a little high, something like 48 would be perfect, I was never dropping below this anyway without adaptive sync technology, so won't need to do this now probably. I am planning to get fastest card possible in early 2017, I don't think that you buy one to play at 40 FPS.

You used this right?: http://www.guru3d.com/news-story/owners-of-freesync-monitors-can-enlarge-hz-range-with-simple-hack.html

Can you point me to where you read people saying about hacking 34UC98/88?

I have made official thread for 34UC88 and 34UC98 here: http://www.overclock.net/t/1597604/lg-34uc88-34uc98-monitors-thread

Post any info there.

PC games have been really badly optimized lately, so I've been having a hard time getting them to run in the "official range", that's why I lowered the minimum. [EDIT] No one buys gaming cards to play at 40fps, nor is that the point of FREESYNC. I lowered the range for those unforeseen dips that you may encounter when a large area loads, or there's too much happening on the screen or you're playing XCOM 2. For such circumstances you need the lowest min possible, so that you don't get jarred by that tearing/stuttering.

However, I'm glad to know that things work out for you, even without freesync ON.

The link that you posted is way too complicated, what I did was a single step simple hack using CRU, you can find out here: http://nils.schimmelmann.us/post/133778060542/modded-asus-mg279q-drivers-with-60-144-hz-freesync

Also here's where you can find the link for 34UC98 35Hz hack, has a pretty neat review of the monitor as well: https://www.reddit.com/r/ultrawidemasterrace/comments/48t11w/brand_new_lg_34uc98w/

[EDIT] Actually that's the thread from where I read that you can use CRU to easily modify the range. Else I was looking into that earlier link that you posted as well.

Thanks for links, will try it once I get AMD card in future. It will be also useful info for some who reads this thread I made for 34UC98 and 88. I posted this info there.

Just got a 34UC88 and I'm really happy with it. Is it real that you managed to enable freesync and get 75hz? Forgive-me but this is a bit absurd for me. I managed to get up to 70hz with HDMI cable but tested for frame skipping and it was a big mess. Tested with Displayport and got up to 80hz but also failed on frame skipping tests. Maybe Displayport 1.3 will be the solution, I don't know. If you have results about this overclocking please let me know, I'll be the happiest person in the world if I can manage to overclock this monitor to 80hz. Anyways, for working this monitor ROCKS.

From my experience with 34UC98, effectively the same panel as UC88:

-you can enable FreeSync even on Nvidia card and this will give you access to 75Hz through control panel, but it will result in frame skipping
-even on AMD card you need to enable FreeSync to get 75Hz option
-overclocking past 60Hz on Nvidia cards is not possible due to intentional limitation applied by manufacturer*
-overclocking past 75 Hz on AMD cads is not possible due to intentional limitation applied by manufacturer*

* - I cannot find any other explaination to those frame skipping thing, for me it means that monitor is intentionally blocked and secured not to operate over supported refresh rates and cannot be overclocked

Thanks for the reply. You seem to be right, as much as I search for more information, so far this is exactly what I believe as well. I exchanged the 34UM58 (1080p) for the 34UC88 recently, and with the 58 I was able to overclock to 75 with no frame skipping (tested with UFO), you actually notice on gameplay. Unfortunately that's not the case for the 88-P, since even creating custom resolution of 2560x1080p @75hz it was skipping frames. This is definitely intentional limitation, and it piss me off because the 15 extra hz does make some difference for gaming (as I recently tested with both monitors). Hope NVidia do something about it, but I don't believe it will be a simple driver update, so my GTX 1080 won't be the solution for that frown.gif

Nvidia cannot do anything about because they have no right or will to do so, and also this is not their thing to do. Those are limitations set by manufacturer to certain product so it cannot be used outside of supported spec and no other manufacturer can change it.

As for difference from 60Hz to 75 Hz... On desktop and for general mouse smoothness it is huge difference and switching back to 60 Hz on desktop is a serious hit, but in games I didn't notice much difference. For fast paced FPS games maybe I would, but I don't play them, and in games like Witcher 3 there was very little difference, and in games like American Truck Simulator it was hard to say if I am running at 60 or 75 Hz.

Anyways, or further discussion about LG 34UC88/98 please visit this therad: http://www.overclock.net/t/1597604/lg-34uc88-34uc98-monitors-thread/110

Well after getting sick to death of the goddamn AUOptronics crap panels frown.gif sigh want high refresh rate, Wanted to get an ultrawide but higher than 60hz refresh rate but without qc issues like acer x34 and upcoming PG348Q. Inc LG's newest panel in the 34UC88. Free sync 55-75Hz Panel.



So Here's the monitor ( It's a mess since I just set it up and doing testing.


So I saw 2 reviews of this panel it was the 34UC98 ( only diffrence that one is white with thunderbolt and this one is pure black without tb and $200 cheaper, one from Tech of tomorrow <- did a piss poor job btw says locked @ 60hz my ass smile.gif Will explain.



1.So I get the monitor and boot it up and im like, what? NO blb? yeah that's right LG has virtually eliminated all BLB it's easily 10000000000X Better than the Predator XB271HU I can't see any glow at all in the corners smile.gif


2. The curve of this panel is more than the older 34UC97 series.


3. So I get in windows (Using 980ti's) and look at the refresh rate says 60hz ok, no biggy right? Let me see if I can scroll down and see 75hz nope. Okay maybe I need a custom resolution? ok set to 75hz without touching pixel clock and any other settings it works? Okay try 85hz? Okay works but haha I get a stupid popup from LG saying "Out of range" anyway. So I Fiddle around with the monitors menu and find a Free sync option and I turn it on (using Nvidia GPU) and bam instant Native 75HZ comes up in the Nvidia control panel with 6-8-10bit color dept. This is where I am so far. Yeah this is a hap hazzard update but I'll continue to do tests on this monitor and at night take some more shots to see how good the BLB really is or is it just fooling my eyes atm.


Will update

Would like an update on this monitor... If you had to create a custom resolution to get to 75 Hz, you almost certainly lost FreeSync, which never seems to work with custom resolutions. Check with the Windmill FreeSync demo. And you can try extending the FreeSync range with "CRU - Custom Resolution Utility". I have an LG 27UD68, and I was able to extend it from 40-61 Hz to 33-61.

I have this monitor, and out of the box it was factory calibrated, and looks beautiful. The only thing is the slight BLB in the bottom left corner. It's not bad, though. DO NOT buy the samsung ultrawide with the VA panel. It was TERRIBLE.

But, how do you even enable freesync? I have a GTX 1070 though. But I heard you can't even do more than 60hz without freesync turned on in the monitor. And I heard nvidia users just get really bad frame skipping anyway..
