LG 38UC99 - 37.5'' 24:10 3840x1600 75Hz IPS FreeSync Strobing Backlight

If Vega was already out I'd probably go down to OcUK tomorrow morning and buy one of these on the spot!!! Shame Fury won't power it sufficiently :( (I am NOT going back to AMD Crossfire, it's ****!!)
 
I'm just wondering if I can live with the strobing setting at 75Hz with me having nVidia cards. I just can't go back to 60Hz tbh.

A Gsync *should* be out in a few months, but it might be looooooots more!!!

and I'm wondering if I should get a 1080 to tied me over until vega, to be fair the fury is not doing to bad and I should probably wait
 
Has anyone tried expanding the freesync range with CRU? I don't have any experience with it and am afraid to ruin something, but maybe there is not harm in trying?

Was able to get a range of 32-80 working however it would only work with the short cable that was supplied with it.

There was no frame skipping on the UFO test at 80Hz and gaming seemed fine when around the low range, not sure if there is a better test method for that as the windmill demo does not go that low?

That sounds great. Do you just edit the screen in CRU and then run the restart64? Could you potentially ruin the screen? Or risk that the image blanks out and you can't get back to windows?

Do you have a link to the test you use to see it working?

I created a duplicate of the existing profile and modified the parameters then restart64 and had to go into Display adapter properties to switch to the 80Hz profile.

It should default back to the 75Hz profile if anything is not quite right but do at your own risk please.
The test is: http://www.testufo.com/#test=frameskipping

Instructions are on the site, you will need a camera that is able to take pics at slow shutter speeds.

To test the low range I looked for the AMD freesync windmill demo, that goes down to 40fps and it was able to show smooth motion with freesync active and vsync off.

At 32 on the low range, LFC (low framerate compensation) should be working so I'm not sure there is any benefit trying lower than that.

I've heard brightness can effect freesync range, I normally have it set to 0 since I'm in a basement but it does seem to work at much higher levels.

Got the monitor more for work than play so I'm back to using it at default 75Hz settings, only have a 390 and playing the odd session of civ VI, will visit it again once vega shows up.
 
Sounds great I have to play with that when I come home. Hitting 30-75 or 32-80 would indeed open up for LFC so that would be great.

Googling I found that nvidia has a pendulum demo that can be downloaded, which should be able to go low on FPS for testing.

Sorry about the power brick Kleitus!!!!

We have some people over from HQ this week so I will mention it directly to them!

Great! Fun thing is the wire between monitor and brick is too short for the brick to go to the floor, and the wire is long enough to have to be rolled up somewhere behind the screen.

The only way the brick could make it to the floor would be if the wire went straight line from screen to floor behind the desk. As I (and most people I know) have a desk up against a wall, the wire would have to go along the wall to the side, and in that case the brick would be hanging mid-air and pull the wire. So only option is to put the brick up on the table, which is not pretty. My table has the same width as the monitor, so it's really tiny and still the wire can't make it to the floor...

If the wire was longer it would give flexibility to put the brick away somewhere.
 
Just tested CRU and it looks like I can make it run 32-80hz too! I just testet with AMD windmill demo and nvidia pendulum demo and both run fine, though they only test between 40 and 60 fps (looks like it dips into 30s too).

Need to test this further. Any risks of running like this all the time?
 
Has anyone managed to test the USB-C with a MacBook 12"?
I am loving the look of this screen and like the idea of having my workstation hooked up to it but also being able to plug my 12" mac in when I need to do something in OSX
