Thanks Omar for your help, the 27 inch you mentioned is a FHD, we have VG271U (27inch QHD) in India at approx 24.5K INR ($330) is a decent one, I have added it in my Amazon wish-list, waiting for more options further.

@BrutalBubu oh wow, guess prices really are totally different in india, yes all of those I mentioned are around $300 before shipping and taxes in the US (except the 27GP850, as I said that one just got released a few days ago and isn't readily available yet).
 
HP X27i is one of the cheapest 27" QHD IPS screens around here, but you have to lower your expectations a little with that budget, at least as far as 27" QHD goes.
 
So here are some 23/24" FHD suggestions instead (10bit, HDR and high color accuracy are not common in this category, so I'll skip those requirements):
Gigabyte G24F (the 24" FHD variant of the M27Q) or MSI Optix G241 (they seem to be almost identical)
LG 24GN600
Acer has various models that only have small differences between them: XF3 XF243YP, VG0 VG240YSbmiipx, XV0 XV240YPbmiiprx
 
Most, if not all of them are actually 6bit panels with FRC to get 8bit colors, but they still have close to or over 100% sRGB and DCI-P3 ratings, true 8bit IPS panels at that size don't seem to be able to do 144Hz or low response times. VA isn't really common at that size either, at least not with all the requirements and the price range.

This one is 2k https://pcpartpicker.com/product/8HF48d/acer-vg270u-pbmiipx-270-2560x1440-144-hz-monitor-vg270u-pbmiipx for 270$
Or for 1080p https://pcpartpicker.com/product/gByqqs/acer-vg270-pbiip-270-1920x1080-144-hz-monitor-umhv0aap02 200$

I'll just throw in some 27" QHD recommendations to keep this short:
 
Gigabyte M27Q is considered one of the top 27" QHD screens on a budget, but only 8bit.
LG 27GL850 seems to meet all your requirements, there's a newer version as well LG 27GP850, but that one just got released and is still a little bit more expensive, or the 27GN800, which is a budget option that is slightly worse on color accuracy, but still good for gaming.
 
All of these are IPS, on VA it's not that easy to get 1ms response times, but most VA panels still perform really well, and if you want curved, you're stuck with VA anyway, there are no curved 27" IPS panels. The Gigabyte G27QC is considered one of the best 27" curved monitors.
 
I wouldn't care too much about HDR, it doesn't work really well in Windows, I tried it a couple days and it caused many issues for not much of a difference so I keep it off for now.

The search for a monitor for many people ends in 2 ways:
 
They purchase a monitor seen on a retailer site based purely on specs and advertisements, and are done.
or
They come to a technology forum and ask for advice.
 
The latter usually results in them asking if monitor A or B is best, or what specs they should look for, and then people reply with suggestion usually based on the same advertised specs seen at retailers and/or 1st or 2nd hand subjective opinion.
 
The problem with this is that the display industry has a hidden world of details that are very important for those who want to make an informed purchasing decision, but seldom few ever get to know these details, details that directly relate to the quality of the display and its true capabilities beyond the usual fluff marketing material. These hidden details are known to enthusiasts who know of the few competent, thorough reviewers out there that can provide those details. But being in the minority this results in advice from such individuals possibly being missed by those who need that advice.
 
This is a guide on what information to look for, and where to find it, beyond the basic and often misleading ‘specs’ advertised by the manufacturers, retailers, and many of the self-proclaimed ‘reviewers’ seen online, so that you may make an informed purchasing decision on your own, for the most part.
 
Let’s start off with an important notice:
Any suggestions given to you for any monitor should be accompanied by a thorough tested review source, if it isn’t then such suggestions will be based purely on subjective opinion, often based on specs alone, which, as stated, can and usually are very misleading and missing lots of important information.
 
Now let’s move onto the ‘guide’.
 
Do not rely on advertised specs, and do not compare advertised specs. If its not a reviewed monitor, you're taking a gamble.
As will become evident as you go through this guide and follow the links to reviewers, the advertised specs can be and usually are very misleading. You can use them to glean basic information like resolution, size, frequency, number of ports etc, but things like 'response time' should be taken with a massive grain of salt.
 
Price:
 
Display Size/Viewing Distance/Resolution
 
Quality:
 
Panel Types:
 
Uniformity:
 
Pixel response speed (Response time):
 
Input lag:
 
Colour gamut and coverage:
This is a section I will not be getting into.
The simple reason being that if it’s an important aspect to you, you should already know everything that needs to be known for your given hobby or profession.
 
For the vast majority of people you won't need to know what things like the Adobe-RGB coverage or DCI-P3 coverage mean and are used for.
It is however tested for by most competent reviewers and so you can look there if interested.
 
Colour Accuracy:
As with above this is most important for professionals and certain hobbyists, however this is still somewhat relevant for everyone in my opinion.
 
HDR and SDR:
 
 
Where to look:
 
Now that we have gone through some of the most important 'hidden' aspects of Monitors, where do you find this information ?
 
As mentioned, reviewers. However, you will need to find those who test objectively, display the results, and ideally also inform you of their testing methodology so you can compare displays across different reviewers.
 
Here are a few places you can check.
 
Why isn’t LTT included?
I like LTT as much as the next person, however, when it comes to display reviews they lack details, and are for the most part halfway between a ‘overviewer’ and a proper ‘reviewer’.
Some of their videos will include information like colour accuracy and gamuts, they may even attempt a basic ‘blur’ amount test, but they are not currently at the level of Rtings or Hardware Unboxed. If you see a monitor on a LTT video and you think it looks good, I would still suggest you check the above sources first before purchasing.
Update: 17/12/22
LTT labs is now capable of providing detailed reviews of displays, keep an eye out for future reviews.
 
TVs as a monitor?
This ‘guide’ isn’t for TVs however a quick word on them
 
 
Why should you trust the above information to be true?
 
Display manufacturers are tight lipped when it comes to specific information about their displays that are not included in their advertisement material. And for good reason, no one wants potential customers to know the faults of their products.
 
However, statements like "the response time spec is massively misleading" can be tested, and has been. Every reviewer who tests pixel response speed comes out with an average pixel response speed that is different from the advertised specs, some even go so far as to try and replicate the advertised spec, and that is where we find out how the manufacturers get away with advertising these figures. They are 'technically' not a lie, just hugely misleading.
 
This is the same for all the above information, reviewers that have shown their testing method can confirm all the tested information they have gathered and it can be replicated, within panel variance, and thus confirmed to be true.
 
With the above information in hand, and links to a few reviewers where further more detailed information can be found, you should have all you need to make an informed purchasing decision when looking for a monitor.
 
 
 
If anyone thinks I should add any information to this post, do feel free to speak up.
 
Thanks to @Glenwing for help with format and error checking.

might see up to 5% effect in minimum frame rates, not something you notice when actually playing the games.
 
idk. After enabling XMP, set the frequency to 2666 and see if it gives as lower timings settings. Usually it does, but I'm not sure how low it will go.
Then I prefer the H370 Gaming 3. Asus one only sells you AURA sync and the brand name, while it cost more and lacks WiFi (which is good when you're trying to sell it in the future).
 
Any chipset can handle RAM voltage much higher than that, it's not an issue.
