So you get home with your shiny new OLED TV, slap it on the wall way too high, and fire up your favorite movie. Your jaw drops from the impressive image quality, but then you move to the side of your room and immediately notice it: an ugly green shift in the picture. OLEDs are supposed to have fantastic viewing angles, so what's going on? Is it defective?
The good news is that there's no need to adjust your set; this is, unfortunately, somewhat normal. Although this issue has been more widely reported this year, it's not new and has been noticeable on so-called WOLED panels made by LG Display for many years. These panels have found their way into OLED TVs by brands like Sony, LG, Vizio, and Panasonic.
Not much is known about this issue. LG Display confirmed to us that minor variations in the manufacturing process cause it, so it varies between each individual unit. There were significantly more reports of this issue in 2024, though, so are the latest panels more susceptible to this? We need your help to get to the bottom of this issue!
If you've purchased an OLED TV in the last few years, we want to hear from you. Using this form, we want to know what you bought, when you bought it, and how noticeable the green tint is on a scale from 0-10, with 10 being the worst. We also invite you to share pictures of your green tint by uploading them to an image-sharing site and sending us the link!
We've bought and tested over 50 TVs with OLED panels in the last few years, and as part of our regular viewing angle testing, we measured the color shift from 0° to 70°. You can see the individual results for all TVs using our table tool, but we can already see a few interesting trends from that data. First, you'll notice that none of the eight QD-OLEDs we've tested show any green shift, even at extremely wide viewing angles. It's also consistent with what we've heard from the community, as we haven't seen any reports of a green tint on QD-OLED panels.
There are also three WOLED TVs that show no color shift. Interestingly, these three TVs all have an additional MLA brightness-boosting layer. Again, this is consistent with our expectations, as LG Display also told us that MLA panels shouldn't have this issue. In this case, the community experience appears slightly different, as a quick Reddit search shows many reported issues, even with the most recent LG G4. It's worth pointing out that many of the original posters of those threads appear to be confusing standard uniformity issues with the off-angle green tint we're looking into here. Still, some of those threads appear to show this issue as well.
So, eliminating the QD-OLEDs and MLA panels from our results leaves us with ~40 OLEDs that we've tested over the last five years. What do our measurements tell us about the green shift on these panels, and is there any pattern?
The above chart shows the range of angles at which the green tint appears, sorted by year. Higher numbers are better, as it means the green tint appears at a wider angle. Looking at this chart, the data definitely shows a wider range of green tint in 2024, but since higher numbers are better, it actually looks like 2024 models are better, on average, than previous years. We only have one unit for each model, so these results are far from representative.
So, if the 50+ OLED TVs we've tested over the years aren't representative, how can we determine how widespread the issue is? Well, we need your help.

The goal of this test is simple: we're looking for any pattern in the severity of the green tint issue. We'd also like to confirm if the issue is actually worse this year and if certain models or manufacturing batches are more likely to experience it. We quite possibly won't find any pattern, which would confirm LG's claims that it simply varies between panels.
It's worth noting that this experiment is far from perfect. Ideally, we'd have measurements showing the exact green shift like in our reviews. Unsurprisingly, most people don't have colorimeters and spectroradiometers at home to take these measurements, so we have to rely on your subjective impressions.
We've just started collecting data, so we don't have any results yet. Check back often, as we'll post tables and graphs with our data as it comes in.
