LG 24GM79G Review

LG 24GM79G Review: The LG is a 144Hz Gaming Monitor revision of the LG 24GM77G with LFC support, Freesync, and some other small changes.

 

Introduction

Yay! The previous "older" model LG 24GM77G had already been a very good choice when considering a Full HD 144 Hz monitor with Freesync. So the LG 24GM79G, but as all monitors, the LG also has some slight disadvantages to competing monitors in this Freesync tournament. So, is it worth to buy? Yes, definitely. But it also depends on the price in your region. What is new on the LG 24GM279G? 1. Freesync 2. LFC (Low Framerate Compensation Support) 3. A matte foot stand 4. and some slight differences within the OSD. Watch the video review on YouTube to see what's in the new LG monitor.

IMPORTANT(!) Updates and new information about the LG24GM79G can be found at the bottom of the article or in the table of contents (if available). Also available within the forum (click here).

Review Updates:

1)
Regarding the Horizontal + moving scanlines from bottom to top. Only visible @ uniform mid-bright image content like gray 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.

Pros & Cons

 

Pro:

Very good image quality out of the box (you have just to set the black equalizer to 0 and gamma mode to your personal preference) "Gamma Mode 3" is recommended
- A Very good price performance (Depending on your location/country)
- Excellent homogeneity (no clouding, no backlight bleed)
- Freesync with a range from 48-144 Hz
- Excellent blacks for a TN panel
- Excellent contrast
- Good gamma settings
- Very good colors for a TN panel
- USB Hub with 2 x USB 3.0 
- Good build quality
- Good foot stand & cable management
- Easy OSD navigation & overview
- Black Equalizer
- Good overall settings
- Flicker-Free


Neutral:

- Backlight Scanning causes ghosting/crosstalk on the upper and lower screen (check the UFO-Test)
- Gamma presets don't has a smooth grayscale but still better than having no gamma settings
- Matte panel coating (Still better than the Asus PG278QR for example)
- Moving vertical lines in mid bright uniform colors

 

Cons:

- A little bit of fewer details in blacks because of the gamma curvature

When comparing the LG 24GM79G to the Viewsonic XG2401, this is 5ms GTG response whereas the Viewsonic is 1ms GTG. Is there any difference visually? Must 1ms MBR be on to achieve similar performance?
Answer from Lim's Cave - February 4, 2018 2:11 pm

No, I don't know why LG has stated 5 ms response time (maybe without overdrive settings or for marketing reasons because of the 1 ms blur reduction) many people are simply confused.

Hey Lim! I have this monitor with a Nvidia GPU and Windows 10. I did the OSD set up just as you explained. LG's website provides "drivers" for this monitor which is a folder that includes, among other files, an ICC profile (file with .icm extension). Should I install/use this in Windows color management? Also, on Nvidia Control Panel, on the tab "Adjust desktop color settings", should I select "Other aplications control color settings" or "Use NVIDIA settings"? Thank you so much in advance. I've been searching online for an answer but can't make sense of this confusion.
Answer from Lim's Cave - February 5, 2018 9:55 am

You can try to install the ICC profile and check how you like the overall image quality (mostly color temperature and gamma since color accuracy within ICC profiles are not "enabled" on the desktop, only with software which is compatible with ICC profiles and can read them like Photoshop etc.)

Regarding the Nvidia Control Panel, I would use the standard settings and only change Gamma if you cant deal with the LGs gamma curvature (details in blacks) but you should note that the overall image quality will suffer then. According to saturation I wouldn't use this option - So leave everything on standard and use only OSD monitor options to calibrate your own preferred color temperature (Warm, neutral, cool)

I just bought this monitor. How did you calibrate it to get 2,2 gamma? Thanks.
Answer from Lim's Cave - March 27, 2018 11:09 pm

Oh mate, I missed your comment.

 

You simply have to choose the "right" gamma settings in the OSD (Gamma Mode 4) and change the gamma within the graphics card settings or simply through windows calibrating. However, the difference between 2.1 and 2.2 is pretty slight + results can also differ a bit in each unit(!)

So if i set the response time to normal i will have 5ms and in order to achieve 1ms do i have to set it to fast? I am a little bit confused. Can you explain?
Answer from Lim's Cave - March 5, 2018 2:19 pm

Just for the understanding: LG is using the same panel as all other manufacturers also are using. ALL TN panels with a stated 1 ms GtG response time will achieve this only when setting overdrive settings to the highest settings. So you will NOT observe any differences when comparing the LG with another TN panel (of course also depending on your individual unit while individual units differ a bit, even in terms of the responsiveness and pixel inversion artifacts etc). LG has stated 5ms probably because of its backlight scanning "1ms blur reduction" feature. Why they did it? We all don't really know :)

I have just bought this monitor, and the horizontal "scan lines" seem really annoying, is there any way to reduce them or eliminating them completely? Thanks
Answer from Lim's Cave - March 12, 2018 10:05 am

No, unfortunately, you cannot remove them. As I also have learned is that the amount of scanlines also differs within each individual unit. My unit was pretty good in terms of scanlines but still with weird moving horizontal scanlines from bottom to top (do you mean these) if so, did you also have tested another DP cable?

6    KindOldRaven    Sunday, 25 Mar 2018 - 2:01 pm
Please note: the horizontal gray scanlines *can* be removed using a custom resolution made with CRU (Custom Resolution Utility). I've tried this on two seperate models of the GM79 and it works. I noticed no change in gamma, contrast or input latency by doing it. I can post a screenshot of the settings to make this work on the forums if needed. It involves setting your refresh rate to a few decimals below 144 or 120 herz (whichever one you're experiences the lines on) and increasing the VTOTAL to 1500. I can't say for sure if this may or may not increase or decrease input latency, but it cannot be felt in any way. Just saying that that's one thing I can't measure from my home.

Thanks KindOldRaven : I also have added this in the LGs forum thread. A Screen for the forums would be awesome for owners of the LG :)

Hey lim, I noticed you said freesync instead amd freesync. So does nvidia able to use this feature?
Answer from Lim's Cave - April 5, 2018 8:14 am

No Freesync always is from AMD. If this monitor would offer simply "adaptive sync" then it would work usually.

Hey, I have owned a c24fg73 monitor from Samsung but sadly I broke it :( I am looking for a new monitor. Which 1080p 144hz monitor would you really recommend? Should I get maybe this one or the Samsung or maybe something completely different. My budget is about 350 euros but it would be great if the monitor were under 300 euros.
Answer from Lim's Cave - June 13, 2018 11:11 am

If you had the Samsung, you are used to those quantum dot colors so you have to keep in mind that every other 1080p 144hz monitors will be weaker in terms of the colors and image quality. I would suggest you the Viewsonic XG2401 if you want a TN and you do not need backlight strobing. If you need backlight strobing (like "fast" and "faster" on the Samsung) then pick the LG. Just that the Samsungs strobing works a bit better with fewer strobe crosstalk and inverse ghosting. So I would stick to the Samsung or the Viewsonic XG2401 in your case probably (:
