Any reason the Optoma EH500 couldn't do 1080p 60hz 3D over displayport?

Thanks, CaptainTaco. I'm very curious about the results. I'll be in the market for a projector later this year. 3D Vision in 1080p at 60hz would be worth a few extra $ to me.

I'm still interested in this discussion as well. The Vivitek D910HD also seems a candidate for an Edid override in order to display 1080p 60hz HD and is not as pricey as the Optoma. It says straight away that it accepts 120hz frame sequential from a computer and has a displayport.

Well I will try testing tonight, but I have to make the EDID override, and it has been a while since I have done that. Need to find an INI that I can use, as I am not good at just modifying the stock ini file (such as using Phoenix to modify the stock EDID to include the proper modes and installing/creating with moninfo) I am at work right now and don't have a lot of free time here, so if anybody has a valid INF I could use as an override, I would be highly appreciative, would make testing tonight quicker and more successful.

That said, another possibility for a projector would be the EH501, as it has the newer DC3 chip, which is more likely to support 120hz (as it is one of the few that can support 144hz), however, I have found little info on 3d FS @ 60hz for it, it seems nobody knows how to test these things. The issue with that one is it does not have a VESA Sync on it, yet in the manual it claims you can turn Active 3D on and off (not just DLP Link) so not sure how that would work... But I figured I would start with the EH500 since I have one, and it does have a 3D vesa. That said, I need an INF/EDID that will trick 3D vision into thinking it is a 3D Ready display (not 3D Play) as we need to run the tests with Frame Sequential, NOT frame packing) Plus, as it seems Nvidia disables their emitter when 3D Play is being used, without tricking 3D Vision into going into regular 3D Vision frame sequential mode I would need a new emitter (which I don't have and would take several days to get in) [quote="CeeJayII"]I'm still interested in this discussion as well.

Plus it is DLP Link only, as specified in the specs, with the projector already being 1,700 lumens dimmer, and DLP link dropping brightness by 3 times or more on top of that, you would end up with a very dim display) This is why I prefer active glasses over DLP link, at least your brightness only gets cut in half with active glasses.

Here is an INF for the VG248QE which supports 3D vision over displayport. You have a 3D emitter, correct? You'll need it at least connected to the computer if memory serves. If you can find a VG278HR inf then you may be successful without an emitter. [url]https://drive.google.com/file/d/0BzmwA3ZUF9stMWlkX1ZnSFhEVTQ/edit?usp=sharing[/url]

Alright... So here is the deal so far. As far as I can tell, 1920x1080 @ 120hz is pretty much out of the question. The issue here seems to be the pixel clock. Regardless of whether I am hooked up via Display Port or HDMI, whether I am using an EDID override, or not, I can only reach resolutions/hz up to a certain pixel clock. The good news? It is possible to get beyond standard 720p 120hz (1280x720). Making custom timings (basically using reduced blanking) I am able to easily hit 1366x768 @ 120hz. Which doesn't seem like a lot... but it is. Furthermore, I am able to hit 1600x900 @ 100hz, which with some additional modding should still allow 3D if you have an emitter that supports 100hz timings. I do not, as I have the nvidia emitter, and they like 120hz or nothing. Basically, the max pixel clock rate (normally HDMI 1.4a and below would have a limit 165Mhz) I can hit is 178Mhz, anything above that and the projector claims out of range. This may be a limitation of the DC2 DLP chip, or may be a limitation of the Display Port / HDMI inputs within the projector, hard to say. If anyone else has any other ideas (I already patched my graphics driver to remove the caps on pixel clocks of HDMI/Display port on the PC end) I would be happy to try them, but I will be busy all day tomorrow, business meetings and dinner and carp... Tonight I will be up for a bit (east coast time) and will continue working on it. At the very least, I should be able to hack apart the stock INF and mash it with the right bits to enable frame sequential @ 1366x768, though I know this is not acceptable for most. Nor is it for me really, but Running out of options. The highest frame right I was able to get 1920x1080 to was 75hz using reduced blanking.

For what it's worth, I have been able to run as low as 85Hz using the pyramid emitter. This one is old, from 3D Vision 1, and they might have changed. But, I ran 85Hz with a CRT years ago, without any trouble.

Okay, second update... I mashed up the ini's until there was basically nothing left, and started from scratch using a 3D Vision compatible ini (the one provided above). I removed all resolutions and capabilities and starting building it anew... I found, over HDMI I was able to reach 110 and 112hz @ 1600x900, for me this is an acceptable resolution to play games at (while 1280x720 I can't bare... too much loss of detail). Is 1600x900 ideal? Of course not, I would much rather 1920x1080, but seeing as 75hz was the highest I could get that mode, and the next 16:9 resolution down from that is 1600x900, I have to work with the cards dealt. To answer previous questions, nope, 1920x1080 @ 120hz is still very much out of the question, so whomever's friend claimed they reached 1080p 60hz 3d (120hz 2D) was lying his pants off... That said, I have a few more cables on the way, including some Display Port 1.2 cables (though I doubt this will help any) just to eliminate any such "well you didn't try everything's." So while, yes, I didn't try the latest and greatest display port cable yet (which is highly unlikely to be the port within the projector, it is more likely DP1.1) I still call fibber to the friend in question... Now, for those of you that find playing games at 1600x900 acceptable, I will continue working out the kinks in the driver I'm building, as there are a bunch still. For one thing, adding back in the 1080p @ 24hz 3D for movies. Me personally, I don't notice the reduced refresh rate in 3d movies, they are filmed at 24fps, you shouldn't need anything faster than 24hz (as the DLP chip itself refreshes the frames at 144hz in this mode, taking care of any motion blur that might be noticeable on an LCD @ 24hz) I was watching a movie at 24hz (not 3d, just forcing 24hz for motion comparison) and did not notice a difference... games were quite obviously quite a different story... Current bugs to be worked out still for me: Nvidia shows the nice "You are outside a valid 3D resolution" in bold red at the bottom of the screen, I need to modify it to get rid of that (had to do it with my Mitsubishi DLP TV too back a few years ago) it is a pain, but doable. Add the other resolutions back in Get new cable in (Thursday or Friday), test modes to ensure I indeed cannot go beyond 173.2Mhz Pixel Clock. I should add, 3D games @ 1600x900 via 112hz looked absolutely amazing... Ideally I would like to have a resolution that is a multiple of 120hz or 144hz, but again, beggers can't be choosers. As I said, it still looked great, significantly better than my DLP TV which used to run Checkerboard 3D @ 1080p 60hz (essentially a slightly higher resolution than 720p 60hz 3D). Significantly better. Any additional questions or suggestions, tests, etc. you would like me to answer/try let me know. I will post updates if anybody cares.

If you can achieve improvements over HDMI, is there any chance this could be made to apply to my W1070?

I salute you, CaptainTaco! Your testing is invaluable. I think the discovery of a 3D 1600x900 112hz projector is quite significant on its own. I'm curious if you could comment on the projector's brightness and picture quality, aside from resolution.

So... now I have been up entirely too late, I just love puzzles... Got rid of the annoying red text at the bottom, though it took modifying the Nvidia driver a little (just removing a font layer from a DLL and replacing it with 100% black (in this case, transparency). Everything is looking good, so I decided to test this projector without using the VESA Sync output of the projector. So instead of having the Nvidia emitter hooked up to both the PC via USB and the projector via 3D VESA Sync, I wanted to see if it would work all on its own (just hooked to the PC via USB.) Lo and behold, it does! This is interesting to me as I have always been told DLP NEEDS the vesa sync... well, that is clearly a false statement, I have been living a lie. The nice thing about this, the EH501 (which doesn't have a VESA Sync 3din port) can theoretically also do 3D via 3d vision with some modding. The EH501 claims it has the ability to turn on "VESA" in the menu, which is actually fairly irrelevant as the EH500 I have here did 3D fine via the NVIDIA emitter even when I switched the 3D Mode to "DLP Link" other than obviously changing the color and brightness, it had no effect, 3D still worked fine using Nvidia's emitter and glasses. So basically, as long as you plan on using it solely for 3D content on the PC (Which I do, I don't use 3D blu-ray or the sort, just the PC to watch 3D movies) it is good to know the 3D vision is entirely segregated from the projector, it does all the syncing... yay... Because of this find, I'm pretty sure I am going to pick up an EH501 to play with lol, after all, it is 400 lumen brighter than the EH500, has longer bulb life expectancy, and has the newer DC3 DLP Chip (which means better, color better contrast, happier Rob (that's me). Perhaps I'll get that projector for the office as well and "try it out" before I buy one of my own... Or as far as that goes, I could buy it myself and keep which of the two I like better, as the office already bought the EH500... And on that note I am off, should have been off hours ago... meetings in the A.M. lol, sleepy, sleepy meetings... WITH A PROJECTOR! Oh... also managed to get 3D working at 1080p... it is just awful... 80hz was the best I could crank 1920x1080 up to, so it was 40hz 3D, just terrible... very flickery, seemed like the Nvidia emitter could figure out what the heck I was doing @ 40hz, it wanted to be higher or lower lol. Will play more.
So... now I have been up entirely too late, I just love puzzles... Got rid of the annoying red text at the bottom, though it took modifying the Nvidia driver a little (just removing a font layer from a DLL and replacing it with 100% black (in this case, transparency).

[quote="Airion"]I salute you, CaptainTaco! Your testing is invaluable. I think the discovery of a 3D 1600x900 112hz projector is quite significant on its own. I'm curious if you could comment on the projector's brightness and picture quality, aside from resolution.[/quote] Tough to say as far as color goes at this point, I am quite literally projecting onto a painters drop cloth I draped over my DLP TV lol. As far as brightness goes... it is amazingly bright, was using it during the middle of the day with my windows open and screen door open, was not having a problem. This is whilst projecting on the drop cloth (which absorbs more light than it reflects...). Of course this was at full brightness. However, on ECO+ mode, it is still SIGNIFICANTLY brighter than my WD-92840 (92" Mitsubishi DLP), and A LOT more crisp. I am currently projecting an image size I estimate to be around 100-110 inches (basically the entirety of the 92inch TV including the bevel. Sound might be your only concern. On eco+ mode it isn't too loud, it is currently sitting about 3 feet from my head, and it sounds no louder than your average PC. However, crank it up to full brightness and it pretty much doubles in volume. That fan can move air! If the projector was going to be 6 feet or more from your head (if you have a high ceiling, mine is only 7.2 feet) or if it was going to be further back in the room, you should be fine, even on brightest modes, especially if you have sound playing, such as a movie or a game. It is only when you sit in silence typing... as I am now... that you start to hear it. But my PC has been that loud for years (only just recently built a water cooled PC) so I am used to it... and hey, put all that effort into making a silent PC now, why not negate it with a projector louder than the PC?! [quote="Pirateguybrush"]If you can achieve improvements over HDMI, is there any chance this could be made to apply to my W1070?[/quote] The same techniques could be used, the issue here is the testing. Each display is different, I might not be able to hit 112hz on yours, so if I was to make a modded EDID for your display, it may just fail anyways. What I can do is post some tutorials later on what it is I did to complete my testing and compile the file, including applications and resources used. This would help you recreate the same testing environment for yourself. Most of the stuff isn't hard if you have all the applications and a quick explanation of what you need to/want to change within them, and what each timing means and does. I can work on that this weekend if you'd like (might not finish it until weekend following) EDIT: Oh, I should also mention, I can definitely post the blank template I created from the ini kindly posted above (the Acer posted by CeeJay above). This way you have a nice 3D vision capable EDID to start with, ready to have resolutions added to it. (I will include a 1024x768 resolution in it to start with so you don't just end up with a blank screen)

If you do get time to write up a guide, that would be amazing. The W1070 isn't 3d vision ready, but 3d tv play - would that make a difference?
