LG 24GM79G Review + Measuring Data / Optimal Settings and ICC Profile

#1
Scanlines-Fix: This CAN fix scanlines on the LG24GM79G. Thanks to KindOldRaven who has posted this in this forum thread: viewtopic.php?f=6&t=318&p=1299#p1299
Make a custom resolution:

I noticed I could see the lines @ 120hz and worse @ 144hz. The screen also has a standard 119hz mode though. I tested that and the lines were completely gone (verified by me, my girlfriend and another friend who can easily spot them). So I went into Nvidia control panel (you can also use Custom Resolution Utility, it's free!) and made a custom resolution.

The only thing I did was set 144hz mode, but change the actual refresh to 143 hz (you have to choose a decimal value between 143 and 144, I went with 143.00hz) and guess what... it's gone! I don't know if it transfers to games but it's a very obvious difference and I thought perhaps you (or others) could try this as well if you've got monitors with this 'issue'. I got the idea from what I noticed at 119hz vs 120 and read that some ASUS models could get rid of the issue by making custom resolutions as well.

This fixes all 'movement' of the screen including those lines whilst it doesn't affect image quality in windows at all.

Please let me know if I'm on to something here if you've got a monitor with visible lines lying around!

EDIT2: For some reason this only works with Blur Reduction off... If I turn it on, the lines are gone at 144hz, but visible at 143, tested 10+ times... Really strange, but true for some reason. Seems to have to do with the fact that Blur Reduction usually only works at 120 or 144hz, by turning it on through FPS1-mode it forces it on 143, causing visible lines.

This is a Freesync Torunament for 6 Monitors - to find out which of these is the best (also in price performance ratio):
Acer XF240H
Asus MG248Q
ViewSonic XG2401
Iiyama G-Master GB2488HSU-B3 Red Eagle
LG 24GM79G-B
Samsung S25GH50

Review Updates:

Regarding the Horizontal + moving scanlines from bottom to top. Only visible @ uniform mid-bright image content like grey and when looking very close to it (from a distance of approximately 30cm). I wouldn't say necessarily that this is a "real" disadvantage. It's by far not that visible like the scanlines from the CHG70 or the PG348Q for example. It also isn't possible to capture this on camera. These scanlines are not as usual "scanlines", they are like vertical thin "darker" bars traveling from bottom to top.

Yes, of course, IPS is better than TN, even 5+ years old IPS panels (mostly - when the contrast is not too bad) It is especially noticeable when switching from IPS to TN and even more noticeable when using an IPS panel for some longer time

For games, I still think the high refresh is the best gaming feature on a monitor. But I also think that you can get used to the TN colors after using it for some (few) days. Let us know :)

You should set the black equalizer to 0 because it also raises the overall black level @the LG.

My settings are here:

But I would not really recommend just to adapt my settings. You should set:
1. your brightness settings
2. color temperature (to your personal taste - warm around 5500-6200K, neutral "whitest white) around 6500k - cool above 6500k) There is not really an "optimum", especially for games
3. gamma
4. and again brightness (because brightness will change a little bit after changing the color temperature)

For CS I probably would increase the black equalizer or the gamma a bit so that you will lose some contrast but increase the visibility of your enemies. Overdrive set to normal. In terms of color temperature and brightness, there is not an "optimum": https://www.limscave.com/best-monitor-settings

If you like to use the Motion Blur Reduction feature (which I personally do) you can use LGs strobing (they call it 1ms motion blur reduction). This, however, is personal taste and you cannot use Freesync at the same time with this scanning feature enabled

By overdrive you mean response time set to normal instead of fast?

Re: LG 24GM79G Review + Measuring Data / Optimal Settings and ICC Profile

No, it doesn't help with input lag, only with the response time. When you coudlnt notice any artifacts then you can try to keep it on fast. However, in some games, you probably will see some artifacts when setting to fast. For black equalizer/gamma is not really an optimum for FPS or other games, this is just personal preference. And it also will not make you better when using settings from other "pro" gamers :)

Hi Lim, first sry for my bad eng i write using google translate :)
I like you review of this tournament.
Because of this i bought my monitor LG 24GM79G-b (ViewSonic was sold out).

So before i had Samsung 2235LW (TN panel) so i was hopeing this new monitor will be same or better looking at colors and image quality. But i was disappointed colors and image quality is worst then 10 years old TN.

But ok washed colors i will try to used to it but brightness is to strong especially on night when i am tired. So i will try to put LED strap behind monitor and i use night mode in windows to little kill white light.

So i copied you settings (i now it is not the same but i hope it will be at least 90% similar). Only difference is i put Gamma 3 and Brightness 0. (now i put color temp Medium to try).
Later i see all 144hz monitors have terrible colors and very strong Brightness.

So sorry for long intro but my question can you please do some test or how to make colors more deep or vivid i am using Nvidia card.

I ask you this because i game World of Tanks i see they have options to make color adjustment.
I will send you pics (they are bad because of cell phone) but you will see what i mean.
I like the mos Deep or costum better colors less white and easy for my eyes.
Ignore vertical lines they are impossible to see with eyes:

I cant post links so i try like this:

Hope you will not ignore my post and sorry for long one :)

Keep doing good rewievs

Did you have set the black equalizer to 0? This is pretty important

So sorry for long intro but my question can you please do some test or how to make colors more deep or vivid i am using Nvidia card.
You cannot do much, even with an ICC profile. If you like intense and pop colors maybe you should try https://reshade.me/ which also works for games. You can check simply some YouTube videos for this

I ask you this because i game World of Tanks i see they have options to make color adjustment.
According to color corrections for world of tanks, you should simply try it out - I am really not familiar with those options in this game, never played it before :P


Just I cannot imagine that the image quality is worse than your 10 years old TN model which probably will have a much worse contrast, especially while monitors (and displays) also looses contrast over time

Hi Lim,
thanks. for your reply.
I copy 100% your settings so i set the black equalizer to 0 and 1ms Motion Blur is on (when i turn it off to much bright) only difference in settings is that i put brightness 0 (you put 4)
My old Samsung 2235LW it had bad view angels but it was not this much bright so it was more pleased to watch and read.

You didnt understand me with my WoT example. I show you WoT settings (pictures) just to tell you what i like. I would like to have more deep color in Windows and everyday work. Because when i read this strong white and washed colors are killing my eyes, in games monitor works ok especially in dark games contrast is good
At this moment when i write you this i am looking at my keyboard not the screen :D

ReShade is for games and some games will ban you for using it, i would like to have stronger colors in Windows i dont expect IPS quality just a little deeper colors and less white.

Hope you understand. I cant take a photo because my bad cell phone and i see lot of horizontal lines (not visible with eyes).

As i was googleing before this monitor lots of people have same "problem" and for older LG 24GM77 there is lot of settings for OSD or driver and for this 24GM79G is only you :)
That is why i am asking you and you are a lot experienced in monitors calibration.

Thanks again.

Hi

thanks to your reviews i decided to buy the lg 24gm79g - 250euro at the time and cheaper than the viewsonic - so thats mostly why i got it to save some money.

I am pretty happy with the monitor itself - good design - the stand is better than its given credit for - i think. since i am coming from an eizo foris 2427bk (ips) i am having some trouble getting used to the colors as they differ alot. most troubling for me is how badly color shifts are represented. the lagom test seems "fine" but sometimes ingame in stuff like WoW or Farcry 5 stuff looks just wonky.

https://cdn.discordapp.com/attachments/ ... 194205.jpg

is an example - i hope people can click on it.

something seems off - maybe thats normal and i am just not used to stuff looking as "ugly" as this or its the monitor - or i was not really thinking when buying a tn panel cuz thats normal.

my settings are probably not optimal either - i am fiddling on a daily basis with it - brightness seems pretty high even on 40 gamma mode 4 and no strobing activated.

anyway - my rambling should stop - just wanna say thanks for the reviews again ~~

I'm not experienced in any of this but have the same monitor. Check the NVIDIA settings on the NVIDIA control panel. Go to Display -> Change resolution. In there make sure the output dynamic range is set to full and not limited.
Yes i did that, and now i put on Nvidia settings Contrast 60% and Digital vibrance 60%.
I am total noob for calibrating monitor and colors, i dont even now what is digital vibrance but now looks little better :D
Its hard to adjust something when you dont even now the meaning what is what, thats why i am asking for help :)

You see i am not the only one, only difference is that Yooi is comparing it with IPS and i just want little stronger colors with less white :)

Edit:
this is popular monitor and lot of people buy it because your review (i read on other forums).
And u said that this monitor have best colors and picture quality? Than i feel sorry for Samsung, Asus, Benq, etc.
If you still have this monitor can you look at it one more time?

Thanks.
