Since you mentioned LG 27UP850, I assume you are eyeing on 60hz monitor. Then I recommend you this.
28 inch 4k 60hz - Asus VG289Q
One of my previous monitors. Nothing fancy about it. But it's working fine in office works/media/gaming. A very good budget friendly 4k monitor, which includes all the goodies such as versatile stand and speakers.

USB-C? Then the VG289Q is not for you since it doesn't have one.

Based on your budget, the one you are looking for is Dell 27 4K UHD USB-C Monitor - S2722QC

I see. Then I guess your eyes somehow cannot adapt to IPS panels. Yes, it's a thing when it comes to IPS monitor. Try to search in google. A lot of users have the same eyes problem with IPS monitor.

If that's the case, the same problem may come back even if you buy that LG monitor you mentioned above, since it's also an IPS monitor.
Therefore, your choice will be very limited. Either go for VA or TN panel. VA is better than TN. So go for that.

Unfortunately, there's no 27 inch 4K VA monitor available. Technically speaking, it doesn't exist.

So here's my suggestion. How about going for 32 inch monitor? If your desk is big and deep enough, I recommend you the Eyecare monitor BenQ EW3270U. Also one of my previous monitors. 4K VA panel. Got USB-C port. I did compare it to my another IPS monitor. And yes. This VA panel is very comfortable to eyes. Good for office works and media consumption.

Here's the review.

It's good for everything, except for gaming.  If you are using the monitor for office use, especially for long hour usage. then this is highly recommended.

Here, this is the seller I bought the monitor from.

Thanks for your reply. I will check on the price of LG 27UP850N again.  I will get one and try. Thank you.

Yes, i also got one at similar price. So far so good when connected to my macbook and windows laptop.

i think the price was good considering the specs with USB-C (90W power supply).
You should receive yours anytime soon. Thinking of getting a monitor arm.

This one?

I ordered the NB F100A. The existing LG monitor stand doesnt allow the monitor to adjust to the left and right. I need this function to held meeting in small room.
