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

Nvidia as far as I know is not supporting 1920x1080@120 via 3DTV Play yet. I'm pretty sure that they haven't increased the pixel clock for their HDMI output either. So you might try the pixel clock unlocker by ToastyX, but it breaks HDCP if it matters to you. Another thing you might try is a DP to HDMI converter. http://www.amazon.com/Accell-B086B-007B-2-Active-Adapter-Packaging/dp/B00F90H77A/ref=sr_1_sc_6?s=electronics&ie=UTF8&qid=1401383882&sr=1-6-spell&keywords=accel+display+port+to+hdmi Of course if the PJ doesn't support HDMI 2.0 and the EDID doesn't reflect the necessary timing and resolution, the adapter may not do the trick.

I'm sorry guys, I have been really busy, between work, planning my proposal, and fixing broken things in my house I have been without time. I didn't even get to play with that projector much more. I did however pick up an EH501 in the mean time, unfortunately with what seems to be the same limitation. I still have not had time to write up a tutorial, but I believe I found a couple on the web that might help in the mean time. I also have the maximum timings that were able to be reached with both the EH500 and EH501, though I have some additional testing to do on the EH501 when I get time, there is a thread on AVS forums with my current testing results.

[quote="Nasugo"]http://www.epson.com/cgi-bin/Store/jsp/Product.do?sku=V11H561020 The Epson 2030 is a great projector, and it claims to support 1080p 3D at 60hz. However, I keep getting an hdmi compatibility warning when trying to do it from the hdmi port on my 780 ti to the first hdmi port on the Epson 2030. When I e-mailed Epson, they said to make sure I was using a 1.4 cable. I have tried http://www.bestbuy.com/site/rocketfish-12-in-wall-hdmi-cable/3721001.p?id=1219093275244&skuId=3721001 (Rocketfish 12' hdmi) as well as a smaller Rocketfish one (6') adapted to another brand, both the cheapie ones they sell "for consoles" (that also claim to be "class 2 and 3D ready" and whatnot. Would I have to use a Displayport to HDMI adapter to go from the Displayport on the 780 ti to the HDMI on the Epson 2030? [/quote] I also forgot to comment on this. 3D TV play does not support any 3d mode other than 720p @ 120hz, or 1080p @ 24hz. These are the HDMI 1.4a 3D Mandatory Frame Packing formats. If you want to test 3d modes outside of these requirements you will require an EDID override as discussed earlier in this thread. I know I am late to respond to any of this, but for anyone that comes on board. You will need the pixel clock unlcoker mentioned above if you want to try anything through an HDMI port that normally would require a Dual Link DVI, plus you will need the EDID override using any projector or monitor profile that is Nvidia 3D Vision compatible, not 3D Play. You can find a list of compatible monitors and projectors on the Nvidia website. So, in short, you need. 1: Toasty Pixel Clock Unlocker (unlocks nvidia HDMI ports to handle higher than 175MHz pixel clock) 2: EDID override of any 3D Vision capable display (one is posted on here earlier in the thread) 3: Create custom resolutions for your EDID using CRU or use Nvidia Control Panel if you just want to test if you can hit the resolution. Nvidia Control Panel is great for testing the resolutions, you can create a custom resolution with custom timings and refresh rates, it is how I got the results above. However, if you want to use those custom resolutions for 3D gaming you will likely have to embed them in the EDID. The reason is, if the EDID already has a resolution; let's say 1920x1080 @ 60hz, and you want to create a custom resolution, let's say 1920x1080 @ 120hz, when you open a game and set the resolution to 1920x1080 the game will automatically use the 60hz version. However, if the EDID has both the 120hz and 60hz timings described above built in, 3D Vision will auto switch to the 120hz version to enable 3D. Most of your common timings will be built into a monitor profile EDID, such as the one posted earlier on here, so you won't have to make any changes; however, if you are like us and have a projector that can't reach 1920x1080 @ 120hz, and need to use an odd timing like 1600x900 @ 112hz, a custom EDID needs to be made. If your Epson does indeed work properly @ 120hz 1080p then you should have no problem with the EDID posted earlier on this thread. That EDID will allow the HDMI cable to be read by 3D Vision as a DVI cable (without a DVI adapter) and should allow you to reach your desired resolution if the projector can handle the pixel clock. EDIT: I should have mentioned. HDMI revision is never the problem, unless you are back on HDMI 1.0... HDMI 1.3 and 1.4 all revisions (a,b,c) have a maximum pixel clock of 340MHz. Like DVI, believe it or not, there is a single link and dual link version of HDMI, however, HDMI Dual link can support a pixel clock of 680MHz, which is far beyond what we need. For all purposes of this conversation, single link is more than enough and likely what is in your devices. Any cable, HDMI 1.3 and newer, regardless of quality will support everything we are discussing, as a matter of fact, there is no difference between an HDMI 1.3 cable and an HDMI 1.4c cable, all revisions within this time frame take place at the port and firmware level, not the cable. I may have mentioned some of this earlier, but figured would repeat for the purpose of this conversation. Now, Nvidia limited their HDMI to a pixel clock of 175MHz, this may have changed in newer drivers, I am not sure, regardless, this is where Toasty comes in. The pixel clock unlocker allows the NVidia card to output HDMI @ a pixel clock higher than 175MHz. This said, it is important for the simple reason 1920x1080 @ 120hz has a pixel clock 369MHz, but with reduced blanking only 285.5MHz much higher than the 175MHz, but still within the range for HMDI itself. Bottom line, as mentioned above, if that Epson can handle the pixel clock, your card can output to it with whatever HDMI cable you have 1.3 or newer, it just needs to be tricked into doing so.

Some projectors have limits built into their software that will display an "out of range" message. Typically this is only on the HDMI connection, so try VGA if this happens. I've achieved 1920x1080@96 on a Frame sequential Projector via VGA, but it was too unstable for whatever reason. I suspect it was the circuitry used in the projector.

I may try the VGA cord then. I'm able to achieve 1440x900@120hz and 1600x900@100hz via hdmi on the Benq w1070 but frame sequential is grayed out when I try to activate 3D. I was able to get 1440x900 frame sequantial active with certain timings but I didn't write them down and tried tweaking them. Now I can't get framesquential to reactivate now matter what I do. I think I may have switched from my Displayport to hdmi adapter back to the normal hdmi jack. I will experiment more tonight, most likely.

Since the Benq 1070 & 1080ST's are 1080P native there's a distinct 'clarity' difference between 1080P and 720P 3D. While I've often thought my rig has enough 'umph' to attempt some sort of 'super down sampling' (somehow faking the games to run at higher than 1080P and down sampling to 720P) I've never had the time or energy to see if it could work or provide a better game play image. Maybe, just maybe getting 3DVision to operate at something slightly better than 720P might do the trick. Here's hoping that it does.

I think this is a lost cause with the w1070. Maybe I wasn't seeing things right when I thought frame sequential was an option at one time with 1440x900 120hz. I can't seem to replicate it for the life of me. Also, every custom resolution that is successful results in red "error unsupported 3D resolution" messages when testing 3D anyhow. Kinda frustrating because the projector is clearly capable but the firmware does not allow me to turn on frame sequential at 1600x900 100hz, which is my aim. That said, I do have more flexibility with the 1.08 firmware than I had with 1.06.

So you can get the W1070 to 1600x900 100hz, but with red text? Is the red text coming from the projector or the graphics card output? CaptainTaco, how significant is the visual improvement?

Yes, 1600x900 100hz with red text from graphics card output. It doesn't matter though as it seems the projector only enables frame sequential at 120hz. CaptainTaco's timings actually work for the w1070 at 100hz, can't hit the same 112hz he got on the eh501.

So what's displayed? Two images? A 2d image? Because that red text can be disabled. If it needs to hit 120hz, could the resolution be lowered a little more to achieve this? What pixel clock have you been using?
