2560 x 1440 monitor with zero back-light bleed

Looking for a 2560 x 1440 monitor with zero back-light bleed. The screen should essentially look like it's turned off when it goes black. Any suggestions?

Good luck... Most monitors are going to exhibit some sort of "backlight" issue to some degree, even between two identical monitors. Lesser backlight-bleed issues can be mitigated by tweaking the settings to where it's negligible and in some rare cases, taken care of altogether.

Your going to get different opinions on multiple monitors from different posters on what's better/worse; i.e. model, manufacturer, panel tech, etc. which is par for the course on all forum Q & A.

However, your criteria is such that it may or may not exist (zero backlight bleed), even between two of the same monitors w/ same panel type.

Best bet is to hit these sites for their expert review to narrow down your option(s):

I'm afraid that those Samsung "Quantum Dot" displays are not truly quantum dot but are just using quantum dot LEDs as backlight and the panel itself is the same old TN. I just looked at specs of one of their QLED models LU28H750UQNXZA and they say:

Display Type: TN

and viewing angle degrees indeed are given as for TN panels and not at least those of IPS panels (which should be achievable with true QLED pixels).

So, it all gets so confused because of marketing. Essentially, the same story some years ago when manufacturers suddenly started adding LED to all of their monitors just because backlight was changed from CCFL to LED. But the main part - the dots themselves - stayed the same TN, IPS, PLS, VA whatever.

If QLED was really used for pixels, then this panel should have no backlight at all and thus exhibit no backlight bleeding at all, and colors should also be close to OLED.

VA panels have less issues with glow and bleed, but they have other issues - such as so called "black crush".
"Quantum Dot", as implemented, is the same thing as "QLED". It is a type of backlight used for LCD panels (TN, VA, or IPS). Typically it uses red and green quantum dots combined with a blue LED backlight, sometimes called "QLED". Quantum dot backlights may be used with TN, VA, or IPS panels, it is an entirely separate component from the LCD panel and is not better or worse than any panel technology. It is better than "LED" backlights previously used with TN, VA, or IPS panels.

Some people (articles) have used the term "QLED" to describe the concept of a display that uses quantum dots as pixels directly, but there are no commercial displays of this type in existence, and so far the usage of the term "QLED" by the industry has been to indicate quantum dot + LED backlights for LCD panels.

@OP for the display to look like it's off when showing a black screen, you need an OLED display. There aren't any OLED monitors yet, aside from a Dell model (U3017Q) that was discontinued a while ago.
