@designs-by-Lucht recommend to use VA monitor. Best contrast , so real black during night and high white during day.

*Both TN and IPS panels tend to have a contrast ratio around 1000:1, although in my testing I have noted some differences. TN panels tend to have the lowest contrast ratios when calibrated, with an entry-level panel sitting between 700:1 and 900:1 and good panels pushing up to that 1000:1 mark. IPS has a larger range, I’ve seen some as low as 700:1 like TNs, however the very best tend to push up higher than TN, with 1200:1 as the upper range for desktop monitors and some laptop-grade displays reaching as high as 1500:1.

Neither TN nor IPS get to the range of VA though. Entry-level VA panels start with a contrast ratio of 2000:1 from those that I’ve tested, with the best easily exceeding 4500:1, although 3000:1 is a typical figure for most monitors. TVs make extensive use of VA panels and there contrast ratios can be even higher. It’s not unusual to see over 6000:1. So if you want deep blacks and high contrast ratios, you’ll need to go with something VA*

What’s the smallest display I could reasonably use?
