The pain of using a TV
I recently bought an LG 55" 4K passive 3D screen. I have been trying 1080p@24hz and there are many problems. First of all it is hard to get games to run at 24hz. It is a lot easier for movies to do so. No 24hz means no 3D. This means I have to settle with 720p which is not thaat bad as the reduced resolution can give better performance. I have used changed the EDID to play with interlaced graphics but that means you are stuck at native resolution to make it work. My single GTX 980 is not up for the challenge and performing dual 4K renders is far too demanding for my good old machine. I wish it was that simple in general. I have been unable to run Mirror's Edge in 3DTV Play. 3D never kicks in and I don't even get the red text about running the game in the wrong resolution. I wanted this game in particular to look at the issue of ghosting. The question is what am I complaining about when I can briefly place my ASUS VG278H in front of the TV and get native full HD at 60hz per eye again.

Thanks to everybody using my assembler it warms my heart.
To have a critical piece of code that everyone can enjoy!
What more can you ask for?

keep the TV. Eventually upgrade your rig to be able to play games in 4k. No reason to have a 4k passive 3d tv just to play 1080p@24hz. Might as well have bought a 1080p Active 3d Tv for that. Keep in mind that Passive 1080p is still lower resolution than 1080p. and if you are playing at 720p that must feel like 576 instead. You're just doing yourself a disservice. Get a better ring in the future and use your tv like its meant to be used (4k EDID with Line interlaced mode)

I never thought about this at this way, even my GTX 1070 have performance issues with geometry 3D at 1080p line interlaced on ultra (of course my slow FX 8350 doesn't help either), i am trying to get a 4k 3D TV, but now You made me think about it, If It is really a good idea. You can use It at 1080p SBS/TaB with 3D migoto and also try tridef or Reshade (SuperDepth3d) which have Very good performance...

Yep top and bottom is the key for you, you can play at whatever resolution you want

The others beat me to it Between TB/SBS and rescaling, you'll find a solution to performance issues almost every time. But there are other common sense reasons to keep the TV and be excited about it. 1. You're going to update your PC and hardware much more frequently than new display technologies appear. In a year or two max you'll have something so powerful that you won't have any performance issues. 2. You can play games, but also watch movies. There are 3D movies nowadays that are so good technically, that they approach "LEGO game style" convergence. They are very exciting to watch on a 3D passive TV, but absolute shit to watch on a 27' monitor (Guardian of the Galaxy 1 + 2, Thor Ragnarok, Star Wars 7, Doctor Strange, the Stassens movies like Sammy, Son of BIgfoot etc, Antman, Spiderman Homecoming, there are too many to name nowadays). You see one once, you'll never go back to anything else. 3. These TVs are technological marvels, and they are no longer possible to buy. It is very unlikely that something better will emerge soon (I'm not buying the recent discussions about ultra 8K TV etc). And even if something better does appear, you have not lost anything. You still have your TV, at least as a backup. 4. Is your TV an OLED or IPS? If it's OLED, then I don't even know why we're having this discussion. Maybe you've seen Bo3b's classification of display tech in order of their quality/impressiveness. Passive OLED was at the top, and he did this on the basis of other people's testimony, he did not even see this tech in action, I think. For me, the only reason I can even imagine why you think about getting rid of it is that: - You got a TV with filter problems, clearly visible with the rabbit test - You did not configure the TV properly, like color and dynamic range and the blacks are still grey and the whites dim - If you place a Passive OLED next to a TN panel monitor, and you still seem to prefer the monitor, then there are other issues maybe with your eyes :-) (Joking, of course) I hope it's an OLED, with no panel issues, and it will probably become one of the best pieces of technology you ever owned. I hope you will have it for many years, and will bring you a lot of enjoyment. For our household it was a game changer. Even 2D movies in 4K, HDR or even older, are a wonder to see. Have fun!

[quote="chtiblue"]Yep top and bottom is the key for you, you can play at whatever resolution you want[/quote] yeah, this is the key - need to play in top and bottom checkerboard mode. You can then play in any resolution full 60 FPS...I pretty much use 1440 for the tough to run games and 4k for the easier to run games. my old Sony passive TV could only accept 1080p tops for 3D signal...so my LG is such a step up, I love it.

As far as I'm aware, the best way to test for a filter problem, i.e. a misaligned FPR (filter) is just a simple black/white left eye right eye test. If the filter is misaligned, then you will see various sparkles etc. where the the pixels get through to the wrong eye. I don't think any device outside of a HMD will pass that test 100% but happy to hear other feedback. In any case, if you bought a high end LCD/OLED then hopefully you're future proofed and the positives outweigh the negatives. I've lost count of the number of reviews that say a particular device is crosstalk free. Outside of a HMD I'm thinking it's always there but they haven't tried hard enough to find it. Neither active or passive is 100% efficient in terms of blocking the alternate eye view.
