2407WFP - left side brighter than right side

well dude, what i will say now is based on MY experiences on LCD displays...

i have also a 2407, i do "amateur" photo editing, and i find it amazing. when i say amateur, i don't mean i do a "bad photo editing" or "i don't need a good monitor", i just say i do it not professionally. I buy this one just because the need of a good monitor.

S-PVA, the panel inside this monitor, IS VERY GOOD. it have great COLOR ACCURACY (0,3 deltaE), great BLACK LEVEL and UNIFORMITY. Low "backlight bleeding", and good pixel response. the bad things about is a bit of "input lag" and is does not have the greatest viewing angles. the big problem about this monitor is not itself, but what people say about it, and about S-PVA. Everywhere, people always try to put S-PVA "down", say bad thing, only "focus" on the bad thing of this monitor, and the worst part, is the part where people say that S-IPS (another panel type) are the "god" of lcds and S-PVA are the lowest quality lcds, and almost the same quality as a TN monitor (TN monitor that are "really bad" for photo). Yes, S-IPS are GREAT panel, with very good viewing angles. very recommended for professional photo editing. But, look first a few things:

backlight uniformity:

this is considered a VERY GOOD uniformity. S-IPS normaly have MORE backlight beeding that causes more uniformity (this vary from monitor to monitor, but S-PVA have much lower number of bleeding issues).

color shift:

this show the level of color shift of s-pva panels. this is LOW variation. if you see, the greatest variation is in the darker levels. this is one of the "not good" specs of s-pva. is cause low gray shades to look different depending on viewing angle. S-IPS also have color shifting, lower than S-PVA, but still have. still, everywhere people say S-IPS are "PERFECT"... Remember the picture you post before, to test uniformity? the image is PERFECT. It have the levels that have the more variation, and have low contrast. And this is the point. You can find this image in a lot of foruns, and i can say: to me, this image is another way to "degrade" S-PVA. look this images:

you can see the same level of variation ? NO! and you can see, the images i posted, are much more "real life" images. if everyone use brighter, more colored images, the
difference from S-PVA to S-IPS will be lower. but, as i sayd, looks like everyone want to "kill" S-PVA and push S-IPS to "heaven" ;)

if i was you, i would calibrate it, and do a "real world" test. use it. if you find the monitor bad for your needs, try a S-IPS monitor. S-IPS WILL be better (not THAT much). if S-IPS still disappoint, get a good CRT display... and a pack of aspirin, for the headaches... ;)

i hope this helps other people too... and sorry for the bad english, im brazilian.. ;)

i get the photos from "print test photos", i didn't choose any, just pick random... ;)

more detail on left? you mean, more detail because of the brightness?

im moving my head around monitor, the only slight noticeable difference is on the picture 3, the rose with dark green back.

if you get a more than "slightly perceptible" variation even on my images, MAY BE a real problem with your monitor... non uniform backlight on s-pva is not common, but can happen.. ;) . my screen is very even, the right side is exactly as left... ive tested my monitor with tons of test patterns, and i found no variation, not counting the little dark shades variation of S-PVA ive talked before..

OT: i do too RAW editing.. ;)

as it should be a backlight problems, i guess they can't fix it...

only changing the monitor... is brand new?

AFAIK, you can replace your monitor with another new monitor or a refund until 21 days after receive it. after 21 days, you will get a refurbished monitor.

ChrisM can explain this better.... ;)
