In that case I am not sure. I would have to know more about how the RGB backlights actually work, and I can't seem to find a diagram or image of one. If they have some sort of array of RGB leds behind the panel itself the dispersion effect from your glasses could be more severe because the light source itself is already spatially separated; however there is a lot going on optically in an LCD and there might be some sort of diffuser involved with the backlighting, so I really can't say. All I can tell you is that the index of refraction and dimensions of your glasses definitely are not changing, so it must be something to do with the light source itself.

Its a GB-LED backlight. http://pcmonitors.info/articles/the-evolution-of-led-backlights

"Rather than using a blue diode coated in yellow phosphor, the backlights combine blue and green diodes with a red phosphor. "

Found this thread due to just hooking up a Dell 2412M as an accessory for my 3x Dell 2713H and the color difference is astounding.

I tried playing around a bit but with very little luck.

Wondering if by chance anyone on here whom has already done the legwork or is more experienced in such endeavors has some settings they want to share? The 27's and the 24 are all at factory defaults.

I am in love with the 27's.. just couldnt afford another one of them as an accessory monitor lol.

Does everyone in this thread understand that this is a monitor aimed at high-end professional graphics work, not for playing games or watching movies? You can't have the best of both worlds. The wide colour gamut is for working with photos and designing prints in Adobe RGB space, rather than being limited to the sRGB colour space. Your colours are looking inaccurate and horrible because they are only using about 60% of the monitors total colour range, which is what happens when you view something designed in sRGB on a wide-gamut monitor. The monitor is expecting a wider range than what you're giving it, so it doesn't use it's full display capabilities.

If you want a good gaming experience, don't bother with IPS, wide-gamut or 10-bit colour. Just aim for high-resolutions and high refresh rates. These types of monitors just simply aren't designed with games in mind. Even for office work and scrolling through documents, you'd have a much better result with a much cheaper monitor.

My partner just bought this monitor (Dell U2713h) for her professional design/photography/print work, and if you've attempted that sort of thing yourself, you may know how it's an absolute pain to print something out, and get it to look the same on screen. Usually you lose lots of shadow detail, colours are over saturated, bright colours are greyed out etc. However a few print tests gave very good results, resulting in much better colour accuracy and detail in the shadows/highlights. This of course saves time and money on corrections and having to do various print tests, as well as resulting in a much better final product. We also calibrated it with a hardware calibrator, and ended up with a brightness level of 5, instead of the factory default of 50 for print-ready editing. This is typical for pre-print editing, as paper does not emit light so you want to be emitting as little light as possible from your monitor so it closely resembles the paper. The monitor has to still be able to display a full, and consistent colour range even at 5% brightness. Monitors like this one do need to be calibrated specifically for the job they are intended to do, and also viewed in light-controlled environments and used in a colour-managed workflow.

I had to do extensive research to find an appropriate monitor for my partner's work (As I'm the more tech-savvy in the couple), and this was the best choice for our budget. Sorry if this post came off as aggressive or cynical, I'd be happy to discuss it further with anyone or if anyone here with photo/print experience wants to point out anything I may have gotten wrong, feel free.

Looking at buying a Dell 2713H which is supposedly better than the 2713HM, except for having more lag, so websites are suggesting the HM for gaming purposes. Does this lag affect stuff like gaming which is fast or will it even affect slow moving video which is what this will be used for?

Planning to use this monitor to watch surgical videos.

The U2713H suffers from very obvious overshoot ghosting which shows up when scrolling text and moving windows slowly, as well as slow movements in movies and games. The input lag is not high enough (30ms when not using the game mode which has very inaccurate colours since it uses the wrong colour space for consumer media=games, movies, tv, web photography, ect) to cause issues in movies, but the overshoot and fact that it is a wide gamut monitor are. Since you obviously do not know what a wide gamut monitor is, you should be running away screaming from the U2713H, especially when intending to use it for watching surgical videos.

The U2713HM is superior in every way unless one needs a wide gamut monitor which they will calibrate with an appropriate colorimeter (250$ i1 display pro) and use with programs which support colour management...but it still sucks compared to the Viewsonic VP2772 which is the only sub 900$ wide gamut monitor which does not suffer from very obvious overshoot ghosting and has more accurate colour presets than its competitors (Asus PA279Q and Dell U2713H).

PS, I know you are new, but if you had read the first few pages of this thread, then you would have needed to ask these redundant and already answered questions.
