Good for what I wanted, but...
It's exactly what I wanted; I had a 32" tv that had been reliable for a few years, however I noticed with it being perched on a tv stand on top of an already tall table, looking up to view the whole screen (solely for playing games I wouldn't know if it was good for anything else) I was getting consistent neck pain. I know easiest solution was changing chairs but I also wanted to downsize because well, 32" is veeery much not necessary. Down to the actual review and not the reason I purchased this monitor. It's a nice size, I know I went for 24" and curved (I don't know if that's a problem but I think because it's a smaller screen size it's decent) I can see the whole screen without having strain my neck upwards which is really nice. I noticed a lot of reviews mentioning about the image being grainy and I don't see any issues so far? (I've not had it long and even if I say I'll update later chances are I probably won't) It's a lot more crisp and vibrant than my old tv was so I give it a thumbs up. Everything was intact and packaged in the box - which leads me to my gripe. My sibling bought this monitor at the same time, same day, but it arrived a day before mine. That's not the issue so don't go there. They received incorrect parts for the monitor. In the diagram of the manual it states the base needs an M5 bolt?? I'm not too knowledgeable about the definitive term but what arrived for them was a rounded head plastic screw. And if it's SUPPOSED to be in the base of the monitor, it's not going to sit firmly on a flat surface. (I am aware it has the option for brackets to be adhered to the wall or a bracket but that also wasn't available in the box either.) So I've bought some M5s for reserve but I am not happy about that I've had to funnel more money for something that was supposed to come with the product as stated in the manual. But because it wasn't my delivered product I didn't mark it down in overall review. The tilt discourse is something I do agree with, it doesn't tilt nearly as much as the image suggests but it doesn't bother me much at all. And for the price of this product at the time of purchase, I can't grumble too much.

Great quality curved was a plus wouldn’t have anything else now LG is the best at a price point
This is the monitor. I thought I should’ve bought the first time around., but didn’t wish I had .. the Colour saturation and everything about the monitor is exceptional

Wasn't exactly as expected
The monitor itself is good but I'll remove 1 star as it feels like somehow a false advertisement. The way it was presented with all the different options were not clear and I expected to be able to change its height but not. Also it comes without speakers but this is mentioned in a kind of hidden place. I don't know if this is the monitor or the different usb cables I tested but using it to charge the laptop doesn't work (event with fast charge cables)

Great Value
I got this for around £75 - remarkable value I think. Connected to my MacBook, albeit using the HDMI lead to a dongle as the USB C didn't want to connect, but might just be me. Tried Windows laptops and all connect easily with HDMI cable. Happy to recommend.

Resolution only 60Hz not 100Hz
The monitor is good but the resolution is not 100Hz as advertised, its only 60Hz....also USB-c cable not included as stated only HDMI....also its not high adjustable so if you want it higher you cant adjust it....

Very Good monitor
Very good LG monitor/display. Colour and sharpness are very good. It does not have speakers but the PC speakers are good enough for me. One issue is related to the stand/base fitting a bit wobbly that is why I gave 4 stars.
