Yikes, my last laptop purchase was in 2010. I'm sad to hear the accountants have taken over.

Oh I forget to mention - RAM prices have gone up by an absolutely stupid amount in the last 18 months (scroll down and look at the "Price History" chart).

Heck, even SSDs with their historically ever-cheapening flash memory have gone up a bit in price over the same period (again, scroll down and look at the "Price History" chart).

...not surprisingly, with memory manufacturers increased demand from mobile and servers yet having taken no action to actually increase overall supply, people are becoming suspicious of price-fixing as such a thing already occurred in the past with computer memory.

LG has quality issues with their backplane technology or TFT manufacturing process. The proof is, that even their IPS LCDs have image retention. The emitter material is driven by the TFT backplane and showing every fault in the backplane and the TFT voltage compensation software. OLED is 100-1000 times more accurate than LCD with an backlight system and slowly pixel response time. Near black, vignetting, banding, image retention etc. - It´s all about the IGZO backplane. Samsung using different backplane technology (LTPS). IGZO is high responsive (great for higher resolution) but also very sensitive to voltage differences. LG´s biggest issue with their WOLED manufacturing process was and is IGZO, but it´s also their key of success.

LG has a collabortion with IGNIS to avoid such issues:

It´s not easy to make an OLED TV, so please stop this nonsense about second-tier status. Where is the Samsung OLED or real QLED-TV (has the same TFT issues like OLED and no blue QDot can reach the lifetime of an blue OLED emitter material) and which TVs winning the shootouts?

What evidence exists that the TFT backplane issues are responsible for the burn-in that lasts several months, that I and others have seen on their TVs? I don't see anything that you've linked in that post, or your others posts, that makes the connection between these TFT-backplane issues and burn-in. I can accept short term image retention and uniformity issues, possibly. The burn-in we're experiencing gets slowly progressively worse over time, and when the offending content is stopped, and only random content is displayed in its place, the screen appears to even out a bit making the burn-in less noticeable. We're talking in terms of months here. That to me, sounds like differential aging of pixels (or emitters).

Regarding your post in the other thread, that red has the highest longevity (3-4 times blue), keep in mind that longevity and efficiency are not the same thing. Red may have 3-4 times more longevity as blue, but red may require 5x, as an example, current in order to produce the same light output as blue. So while the red material may inherently last longer given the same current as blue, it may output a lot less light than blue at that same current, thereby requiring more current to output the same light level as blue. Again, longevity vs efficiency.
