Monitors

I have the WM UHD420 and it's fantastic. I should get around to doing a small review of it sometime in the near future.

No issues? I was looking at Amazon and in the product description they have

*This monitor may have up to 5 dead pixels*
*AH-IPS panel has Little Light Bleeding*

I assume all monitors have a certain number of dead pixels and its not just LG specific, since it has over 8 million of them. Unless Amazon is selling re-manufactured or returned items.

Disclaimer: This is a very quick reply and not a full review by me or anything like that. There wasn't much proofreading.

Amazon isn't actually selling them, and it's a third-party seller who sells them direct from Korea. I bought mine off of eBay about two months ago and was well aware of the mess that I might end up getting myself into, but the overseas Korean monitor market has been around for awhile, and a large majority of peoples' experiences have been nothing but positive over the years. These monitors are not ultra-perfect grade A panels and that's why they're a lot cheaper, and while I don't have a specific link handy at the moment to describe exactly where the monitors come from, I'd recommend reading up on these types of monitors on forums like overclock.net (here's a link to the UHD420's OC thread).

You pretty much always take a risk with dead pixels on any monitor/display since every manufacturer has their own dead pixel policy for what is allowed and what isn't, and it's generally in the fine print. However, my UHD420 arrived with zero dead pixels on it. I also talked both crum1515 and Kicksome into buying a WM UHD420 from the same guy on eBay, and while crum1515's had a small cluster of dark pixels which he claims is hardly noticeable unless he's looking at something very bright, Kicksome's display doesn't have any defects. For the record, crum1515 got some money back from the eBay seller because of that discrepancy, but could have asked for a replacement (he just didn't want to wait).

As for the light bleeding, I imagine they're referring to "backlight bleed," which I'm not even entirely sure I know what that is. If you Google backlight bleed you're met with a range of different images and people trying to explain what they feel it is, and then you've got others talking about how "IPS glow" is completely normal—So, who's right?

Either way, here's what I can tell you about the IPS panels I've owned over the past year...

If I eliminate every light source in my entire apartment and make it pitch black, and then put a fullscreen motionless black image on the screen... there is some glowing around the edges, but it's certainly not anything I ever notice during actual use of the display in any normal, everyday environment.

Here are some other reviews/unboxing of the WM UHD420:

PCPer
Tek Syndicate (just watched this today and it's pretty spot on)

Now, there's one issue with this display that neither of those reviews talk about, and it's the fact that there is a slight portion of the monitor that looks as if it's "cut off" when viewing it from an angle (video). To be completely honest, I was not ready for that when I purchased the display, and if there was anything about the display that made me regret the purchase... that was it. However, I initially adjusted my desktop resolution through the nVidia Control Panel (no idea how to do it on AMD), and everything was perfect after that, but a few weeks ago I reverted back to the full 3840x2160 resolution and I'm totally fine with the edges of the display being a bit weird. In fact, I barely notice it at this point, and if it was to ever become a problem, then I'd just switch back to my 3802x2138 resolution and everything would be 100% perfect again.

I should probably work on an actual review sometime this week or something since there seems to be more people interested.

Thoughts on ultra wide monitors 21:9? I have often thought of going back to single monitor boxing.

I have been looking at a few 34" ultra wides

My 8-year-old Doublesight DS-263N (which was pretty awesome for ~$650 when I bought it in 2008) in a pitch-dark room:

My Asus PB278 (you can see the edge of the DS screen next to it):

And that's with the DS brightness at ~20% and the Asus at 0%. The Asus is an LED-backlight versus the fluorescent backlight of the DS. Off-axis viewing greatly pronounces the corner "bleed" on both. The DS wasn't that bad when it was new, and it actually had the best black levels of any of my displays; the LED backlights are a ridonculous improvement, especially in bright rooms.

There is an ISO standard for pixel defects in flat panels. https://en.wikipedia.org/wiki/ISO_92..._pixel_defects

Of course any manufacturer seller can specify their own policy and do not have to abide by the ISO standards at all, but certainly when the older ISO standard was in force, https://en.wikipedia.org/wiki/ISO_13406-2, and the LCD market was young, it was quite common for a brand new expensive LCD panel to have pixel defects under the ISO standard, and the monitor would not be replaced, especially if the defects were not in the "centre" area of the screen.
