Is this too much backlight bleed?

post #1 of 4
Thread Starter 
I just recently ordered an Acer X34 Predator. I have 30 days to return it so I'm wondering what I should do. I'm offered a free refund so I think it's worth taking.

the photo is overexposed mate. Try 1/8s exposition time and lower the ISO until it looks like IRL. Also turn off the light and do it in complete dark.

That's with all the light's off lol. I would have to wait until tonight in order to take a new picture of it. Personally it's fine except the bottom left corner is a little more than I would like.

Is that supposed to be a black background? Because the colours seem to be very off and not uniform. If not, try with a black background. You can use this site to generate a black background: http://tft.vanity.dk/MonitorTest_pureHTML.html. Go into full screen (F11 in Firefox) and scroll down a bit to hide the toolbar.

You might have to calibrate your gamma and brightness/contrast ratio as well. For that, I recommend you this: http://www.lagom.nl/lcd-test/gamma_calibration.php. To do a proper gamma calibration you need to adjust the RGB values with your monitor by matching the striped parts with the uniform parts at 2.2 value. You might not be able to come as close that they blend perfectly as your monitor is not designed for perfect colour rendering but it has an IPS panel so it's pretty good.

Also, if you don't want to waste too much time, read this review as TFT Central is one of the best in the industry and they also calibrated the monitor: http://www.tftcentral.co.uk/reviews/acer_predator_x34.htm#calibration. Oviously you can't just copy those values and have a perfectly calibrated screen as every panel is a bit different and even moving the screen a tiny bit could result in decalibration but you should come pretty close to ideal and from there you just adjust it slightly. Also you should let your screen on for 10-15 minutes at least to warm up before doing calibration.
