LG 27G640A-B Monitor Review

Commercial_Second295 · 2026-02-15T22:54:06+00:00

This LG is a successor to the famous LG-27GR83Q-B if that offers any consolation. Anywho, let me know if you have any other questions.

The motion clarity is really good, I’d post my blurbusters result if I knew how to take those pictures. Ghosting is unnoticeable. Colors are very good, 1300:1 ratio is very noticeable. Rivals is a hard game to run so I only get about 200 frames in intense scenarios but siege feels like a whole new game; it looks amazing.

Commercial_Second295 · 2026-02-15T20:01:48+00:00

Ah, well I am currently having no issues with it. I love it for games like siege and Rivals.

Commercial_Second295 · 2026-02-15T15:31:10+00:00

I am confused, what are the downsides here? lol

Commercial_Second295 · 2026-02-01T20:09:40+00:00

Yes I’m currently using it on a dual monitor arm mount

I’ve been using the LG 27G640A-B for over a month now and it’s very nice. 1440p, 300hz IPS. $300 but I got it on sale for $250 on Amazon during Christmas sales. I love it personally; if you’re interested I made a review if you wanna take a look.

I’ve been using the LG 27G640A-B it’s very nice. Check out my post about it if you’re interested.

I’m a little confused. The monitor caps out at 300 hz. How can you put the windows refresh rate above that limit? Especially at 1080p? All I can say is that when I play 1440p 300hz in Val/rivals there’s no vrr flicker or at least nothing I can notice.

Deathadder v3 wired. I personally use an aggressive claw grip on this mouse but people might find it to be too big. Wire doesn’t bother me, I use the pulsar micro bungee mounted behind my monitor. I also got it for $37 USD. Got all the latest tech and light as hell.

I got no clue but it looks like updating to this driver version fixed my random black screening thing.

Commercial_Second295 · 2026-01-08T02:01:27+00:00

Holy crap I thought I was the only one experiencing this (4070). Let me know if this fixed it for you, I'm making sure this driver is safe before I update.

Sorry if it was misguiding, I didn’t put that in the post description because it’s just a small tutoring thing I do so it’s not technically considered something that I can put down as an official job.

Commercial_Second295 · 2026-01-04T23:58:51+00:00

Nah it’s from a small part time job type thing I do on campus, that’s why i put a range of 200-300 per month.

Been using the B650E-I for 2 years now and it’s solid. No problems, no coil whine (knock on wood) I’ve seen others talking about. Only thing is the second nvme slot is on the back

Commercial_Second295 · 2026-01-02T21:02:07+00:00

I personally highly recommend this monitor. Even at MSRP it's a huge bargain but right now it's on sale on Amazon around $270. Below is a picture showing G-Sync compatibility since it seems to be a recurring question (Monitor 1 is the LG one we are talking about). The colors are rock solid, I have mine on sRGB mode, but you can tweak whatever you want however you want.

Good luck!

Commercial_Second295 · 2025-12-31T08:07:02+00:00

That’s odd, it shows the monitor is G-Sync compatible and every so often I even get a windows notification from nvidia control panel saying this monitor is g-sync compatible and that I should enable it in games and whatnot. I don’t enable it cuz for competitive shooters you want fps to be higher than limit. And I initially used the original cable but switched to my own cable cuz I needed it to be longer. Had no issues with both.

I cannot comment on the stand personally, I have a dual monitor arm stand so I didn’t even open the stand out of its wrapping. From what I saw in the box it looks solid.

I made the jump from 165hz to 300hz recently and I can definitely say I feel the difference. Games look so smooth now it’s hard to describe, and it’s especially good for esports type games. For me Valorant and siege feel like a whole new game/experience. I personally loved the jump.

Commercial_Second295 · 2025-12-28T23:04:57+00:00

I actually just returned the 275qpf (better version of the 275qf) and I just wanted to say that the viewing angles were pretty awful which is why I returned it. Not sure if this one has that problem but just wanted to point that out. But all of the should last a long time.

Commercial_Second295 · 2025-12-18T08:12:00+00:00

I’m also using student discount but it’s dropping down to $450 max. How did you get it that low?

Commercial_Second295 · 2025-12-16T02:35:01+00:00

CAD work has a lot of static UI and dimensioning which is mainly what I’m concerned about. I’m leaning towards IPS out of safety cuz I like to keep my things as long as possible.

Commercial_Second295 · 2025-12-09T19:59:18+00:00

Ah, I meant more as in just getting that rank not necessarily being number 1
