LG 34UM95 and LG 34UM65 Owners Club - Page 123

post #1221 of 1296
Should I go for an RMA on this? Bought it via Newegg for $570 few days ago. Wondering if I exchange it I'll get the same issue. What is everyones thought on this? The image actually looks worst than it is. It's not bad except for the lower left corner which has obvious backlight bleeding. Let me know your thoughts everyone.

Pulled my info from various sites I get this calculation:

3440(+blanking)*1440(+blanking)*24bit*60hz*1,25 (for TDMS 8bit/10bit enconding) [the values for 3440+blanking and for 1440+ blanking can be looked up in the GPU driver when making a custom resolution and selecting CVT-RB for example)

3600*1481*24*60*1,25 = 9.596.880.000 bit/s or 9.6 GBit/s and DP 1.1 supports 10.8 GBit/s
Are you sure DP 1.1 supports 10.8 Gbps? I looked around a bit and though I do see one document showing high bit rate operation with four 2.7 Gbps channels (http://ftp.cis.nctu.edu.tw/csie/Software/X11/private/VeSaSpEcS/VESA_Document_Center_Video_Interface/DportV1.1.pdf),

most of what I see indicates DP 1.1 is limited to 8.64 Gbps, including the wiki article (https://en.wikipedia.org/wiki/DisplayPort#1.0_to_1.1),

and a presentation by VESA (http://www.vesa.org/wp-content/uploads/2011/01/ICCE-Presentation-on-VESA-DisplayPort.pdf).

hello i see LG released a win10 driver recently for the 34um95, do it fix the issue with standby ?

@atheus

I must be correct. Because I can set the monitor to DP 1.1 and can use 3440x1440 @ 60hz without problems.
8,64 is with overhead and 10,8 without.

10,8*0,8=8,64

Hi everyone.
I am looking to purchase either a 34UM95 or 34UM94.
I keep seeing people here say that they are identical monitors... I have some concerns though.
As we will be using this monitor for photo editing, the most important features to me revolve around color accuracy and calibration.

Here is what concerns me:
1) The 34UM95 is advertised as "Hardware Calibration Ready" but the 34UM94 does not have this distinction in the feature set.
2) The 34UM95 is also advertised as "Factory calibrated". The 34UM94 specifically says it is NOT factory callibrated in the technical specs on the LG website.
3) The warranty on the 34UM94 is better.

#1 is a fairly major concern for me. I really wan't to make sure that I can calibrate the monitor directly in HARDWARE. It is a more accurate way to calibrate.
#2 in itself is not a huge issue, but it gives me the feeling that the display for the UM94 may not have went through the same sort of quality inspection the more expensive UM95 did with its factory calibration.

i'm like 99% sure I got the 94 (through massdrop). It had a calibration sheet in the box, showing that it was calibrated, and you can buy a hardware calibrator to use with it from LG, or get one of the third party ones no problem. i'm actually probably gonna pick one up soon to use with my TV as well

Yes, we use a Spyder5 calibrator. The thing is, these calibrators and calibration software can store the curves in either the ICC color profile OR the LUT for the monitor, depending on whether your monitor supports hardware calibration.
My fear is that the UM95 actually stores the curves in the LUT... but if the truecolor software detects the UM94 it just dumps it in the color profile. To most users they would never know the difference.

Either way it works and you can get a calibrated image. I just like the idea of correcting the color AT THE MONITOR instead of compensating by skewing the signal coming from the computer via software.

I used an ICC profile when I went online to find a good profile, but you're right, I dont know the difference tbh
post #1229 of 1296
Basically, any monitor can be calibrated with calibration software. (maybe not effectively, but that's another story).
If the monitor supports hardware calibration the software will communicate directly with the monitor and make changes in the monitor to sort out the color. Otherwise, it will create a color profile that is stored in the OS which is used to offset the deficiencies of the monitor.

It's a matter of correcting the problem at the source, or compensating for the problem.
For color critical applications, hardware calibration is always preferred.

ahhhhh, makes more sense. yeah im not sure then, since i dont own a hardware calibrator
