Size

The diagonal is the number used to describe the size of the screen. The most popular sizes are 24 and 27 inch screens.
Response Time (GTG)

The time it takes for a pixel to change from one shade of gray to the next. A low response time provides faster response to our actions (input lag) and a cleaner image (less ghosting) which are important in gaming. Response times below 5ms are considered acceptable, but for gaming, monitors with 1ms are recommended.
Connection Type

DisplayPort

Modern way of digital transfer of image, sound and data, compatible with HDMI and DVI cables through an adapter.

HDMI

The type of connection used by popular gaming consoles such as Playstation 4/5, Xbox X/S, Nintendo Switch, etc. (Support for HDMI 2.1 is required for high fps and 4K resolutions.)
Refresh Rate

Refers to how many times the screen image is refreshed per second. Screens with a high refresh rate offer a competitive advantage as their image is clearer (less motion blur).

2. Typically, for office applications and simple gaming, 60-75Hz is common. In recent years, screens with 120, 144, and even 240Hz have emerged, mainly aimed at competitive gaming.
Type

The technology used by the screen to display the image.

IPS

IPS panel screens offer vivid colors, wide viewing angles (the image does not distort much when viewed from the side), and are energy efficient. Suitable for video and image editing.

Purchased solely for use with PS5.
For a budget IPS 4K, it's just what you need.
User-friendly menu, you learn it quickly.
Sturdy stand, you can move the screen up and down, as well as left and right.
Extremely satisfied with the purchase and overall experience.

After about 9 months, the lighting on the left side randomly goes out. I have tried both HDMI and DP with and without an adapter, but the issue is with the monitor. Disappointing. Look into DELL instead, I have had one for 7 years and it hasn't had any issues.

Quite good screen, good colors, fast response and the fact that it is tilt, pivot (although I haven't used them yet) is a big plus.

I deduct one star because in very sunny conditions the clarity is not as good, but it is not a problem

It is a sleek and very user-friendly screen. It has a very beautiful image and I bought it because it has very good color representation and it is 4K. Don't forget, of course, that you also need speakers, it doesn't come with them!

This specific monitor is one of the best options for budget 4K IPS. When I read texts on the computer, I switch it to reader mode to make it more comfortable for the eyes.

Obviously, with 300 nits brightness, it is not a good choice if you want HDR, but to some extent, it is satisfactory (for HDR, use the HDR Effect from the monitor settings, not the Windows settings).

It has 2 cables included, one HDMI High speed and one DP (1.4). Both are capable of 4K 60fps (Although personally, I bought a new 3m HDMI cable because the one it comes with is about 1.40m if I remember correctly).

Important note: The difference between this and the LG 27UL500 is *only* in the monitor stand. The 550 has height adjustment and tilt up to 90 degrees, while the 500 only has tilt forward and backward at 5 and 15 degrees respectively. If you find them at the same price, get the 550. Something similar applies to the 600 and 650 models, except these have 350-400 nits brightness (not 300).

It is amazing, I have nothing more to say than the previous reviews.
I use it daily for over 8 hours. The only negative is that you can't see well if there is sunlight behind you.. Otherwise, it's amazing!

I was looking for a monitor for the PS5 and since I had it in the living room on a 4K TV, I didn't want to settle for 1080p resolution because it would "bother" my eyes...
If the PS5 supported 1440, I would definitely go for that to have good resolution and 1ms for gaming, but luckily this monitor is amazing and I don't regret it at all!
Imagine 4K resolution on a 27-inch screen, incredible image!!!
You can navigate the menu in 10 seconds, you know it by heart!!!
The stand is everything and the plus is that the screen rotates!!!
It may not have built-in speakers, but it has a 3.5mm mini jack input and you can use any speakers you want!!!
If I notice anything wrong with the screen, I will come back!
Update 24/9
Everything is perfect with the screen, no issues at all!!!
Update 18/12/22
It works without any problem or issue!!!
Flawless, just like in the beginning!
Update 24/10/23
The screen works perfectly like the first day!
But I will go for something newer with 1ms, 144Hz, and 4K!!!
Note that not all monitors support 120Hz on the PS5!
I'm not saying this, Sony itself says it!
You can call Sony and ask!
It's good to research thoroughly and not spend money on something that won't reach 120Hz!
