LG 34UM67: UltraWide FreeSync Review
by Jarred Walton on March 31, 2015 3:00 PM ESTLG 34UM67 Display Uniformity
Given the size of the display, creating good uniformity can be difficult. Most of the display does reasonably well, with the corners tending to vary a bit more the center. The left side of our sample in particular looks a bit dim, but it’s only something you really notice when you look for it.
Starting with white uniformity, the center ends up being close to the brightest area, when most other sectors dropping off slightly. The center portion along with the bottom are all within 10%, which is a good result, but the top left and right corners fall off by up to 15%. Professionals would appreciate better uniformity overall, but for gaming the LG 34UM67 works well.
Black uniformity interestingly is a bit of a reverse from the white, with many areas showing slightly higher black levels than the center. However, our i1 Pro is not the best device for measuring black levels and the actual difference between 0.315 cd/m2 and 0.387 cd/m2 isn’t all the great when looking with your physical eyes, even though it’s a 23% difference. There’s a lot of variability in the charts, but mostly the corners seem to be the biggest outliers.
Compared to our earlier calibrated results, or uniformity contrast measurements have all fallen off quite a bit. Our measured contrast this time ranges from 465:1 on the bottom-right corner to as high as 662:1 just above the center, but I think most of the black levels were measured too high so the contrast results are only moderately useful.
Delta E shows similar uniformity again. The top-left edge and top-right seem to have the greatest variance, but for a non-professional display most of this discussion is academic.
The short summary is that uniformity on the LG 34UM67 is good but not exceptional. There will obviously be differences between panels, so where we had problems primarily on the corners and left/right edges, other displays may show more or less issues. Perhaps the most telling aspect is that prior to testing uniformity, I looked carefully over the display with a variety of solid background images to see if I could detect any problems. There are some very minor discolorations that show up primarily when viewing pure white, but the size of the display makes the corners more of an acute viewing angle so it often feels like that’s as big of a problem as display uniformity.

So freesync is low fps sunk.Another amd failure, no surprise there.
Plus high fps sunk.
Just a tiny near worthless middle ground - again...
Now you know why nVidia actually made technology happen with new hardware, while amd claimed it is everyone else's job to do it, to make it work for amd.
Freesync is only free for amd, no one else.

Don't forget it doesn't work with most games because the aspect ratio is wrong.ROFL
Epic failure # xxx for amd.
I can hear it now- "It's not amd's fault"... blah blah blah blah - yeah they sure "worked with" the "industry" didn't they. There's probably a boatload of unresponded to emails and phone messages sitting in the mad to do box - well too late again amd.
It's someone else's job, right...

So... because this one monitor isn't to your liking, FreeSync is an "epic failure" for AMD? That's some stellar logic right there.Those not hopelessly poisoned by fanboi-ism will note that there's no lack of released and pending FreeSync monitors running a wide range of sizes, aspect ratios, refresh rate ranges, and panel technologies.

Whats wrong with 21:9 aspect ratio? All but the oldest games have no problem taking full use of this aspect ratio. Have managed to enable it on may of my old favorites and new games have no trouble with it whatsoever. So 21:9 aspect is nothing to be afraid of.bizude - Thursday, April 2, 2015 - link
You're an idiot. 99% of games out there work flawlessly with 21:9 monitors.AnnonymousCoward - Saturday, April 4, 2015 - link
"flawlessly"? No, 99% of the games listed here are not Hor+ Native. http://www.wsgf.org/mgl?page=1bizude - Sunday, April 5, 2015 - link
And that list is flat out wrong. For example, it lists AC 1 & 2 as not supporting ultra-widescreen, but both of them work with ultrawidescreen resolutions "out of the box". If you'd like, I can take screenshots for you.AnnonymousCoward - Saturday, April 4, 2015 - link
Jarred,-Watch out for overdrive. I think on the older Samsungs with it, it made input lag horrendous. Overdriving might always require at least 1 extra frame of buffering/processing.
-For gaming, I think the higher the color gamut the better. Allowing a full range of saturated colors is more realistic for your eyesight. I see it as ok for 3D rendering, which is different from viewing pictures saved on a reduced gamut space.
-It's inexcusable to have no height adjustment on a huge monitor like this one.
-For general desktop use, the AOC Q2770PQU 27" 2560x1440 seems better. Vertical space is too important.
