It's recommended that you sit as far as 3.4 ft to 3.6 ft away from a 27 inch monitor.
However I sit around 14 inches from my 27 inch monitor and that distance works well for me but some people want to sit a bit further.
The best resolution for a 27 inch monitor is at least 2560 × 1440 pixels (WQHD), preferably 3840 x 2160 (also referred to as UHD 4K).
1080p is worth it on a 27-inch monitor and there is no pixel door effect especially when watching media.
Although for 27" 1080p falls on the low side.
And if you work with any text and have sharp eyes it's suboptimal.
But for picture it will not "look bad".
But if you decide on going up on res, 27" would be a waste as you can go all the way up to 32".
165Hz is better than 144Hz especially if you're gaming.
Any game that runs at 165Hz will be smoother than 144z.
If you can't spend much or are on a tight budget or prioritize other monitor features, a 144hz monitor is a fantastic option.
But if you have a powerful graphics card, and don't mind spending a bit more, a 165hz monitor might be the way to go.
240Hz and 360Hz monitors also exist but they require incredibly high-end hardware to run such high frame rates.
165Hz hits a nice balanced sweet spot for buttery smooth gaming without cost or performance overkill.
Popular gaming monitors among professionals include ASUS VG248QE, a 24-inch monitor with a 1080p resolution, a 144Hz refresh rate, a 1ms response time, and a TN panel; BenQ Zowie XL2546, a 24.5-inch monitor with a 1080p resolution, a 240Hz refresh rate, a 1ms response time, and a TN panel; and LG 27GL850.
A curved monitor provides a more immersive experience than a flat monitor, which is why gamers prefer it.
When choosing a gaming monitor size, start with your anticipated distance from the screen.
24-inch monitors are best for distances of 3 feet or less.
27-inch displays work well for 3 to 4 feet.
If you are interested in a larger gaming monitor, 32-inch screens work best when sitting about 5 feet away.
The difference between a top-tier gaming monitor and a regular monitor can be significant, with top-tier monitors offering: Higher refresh rates, such as 240Hz or 300Hz, for a smoother gaming experience.
Faster response times, such as 1ms or 2ms, to reduce ghosting and blurring.
