You already received it, right? - I got a read receipt. If not, you need to straighten out your email, as previously instructed.

Hi everyone! I have a problem with my LG BN315 projector, which worked for about a year under Vista, but something happened and now it's recognized by OS as an analog display. Power strip shows me empty EDID and nobody wants to help me in LG support... Angry Please, guys, help me with this thing, I don't know where to get an EDID file

You need to get an EDID from LG or a fellow owner - you aren't likely to find one just laying around the net.

But its not going to help because even if LG replaced your PJ with a new one, the same thing is going to happen again.

You need to identify and fix *this problem* - the something that happened - or it will keep happening.

LG isn't going to help anyway. I have their warranty, but would like to solve this problem by myself - they'll identify the problem for a month or so. Is it anyway I can copy EDID from another user of BN315?

I can see raw data in registry by Moninfo. Am I able to make an EDID using this data? And if yes, by which program?

Hi, guys!

I'm encountering the same problem as the topic starter, with the same monitor (BENQ FP241W)... Mostly I cannot see even the BIOS POST messages on DVI-D. Only in very, very rare cases (if I reboot very often), DVI-D is working here. VGA is always working fine.

This time DVI-D is working, so I took the chance to run softMCCS on this device (vga is also active, attached to the same monitor, just in case that you also need that output). Does it seem like an EDID corruption? Also the "Timing string = Invalid data (2,85 kHz, 22,09 Hz)" looks odd to me. I'm really not sure if it's a failure of the graphics card or of the monitor Sad the graphics card just came back from an RMA.

Here's the log file:

The EDID is ok on both inputs, though its not clear why Benq recommends 640x350 on this display. The invalid numbers for timing data just mean Benq's firmware doesn't know how to respond to a GetTiming command - nothing you can do about that.

I would suspect the cable itself, and the cable connection - coupled with the fact that you have two inputs on the monitor connected to the same PC - with the DVI failures. Make sure the DVI cable is securely fastened at both ends, and - this is important! - disconnect the VGA cable from either the Benq or your PC, and you should be all set.

Thank you very much for your reply!

The additional VGA cable was, of course, only attached for running softMCCS ;-)

Btw. the dvi problem wasn't always there, can dvi cables suddenly be broken? If so, the current cable is a DVI-D 18+1 cable. Is it safe to buy another 18+1 cable or are 24+1 cables better? (If I recall correctly, the Benq FP241W only uses single link dvi, but I'm not sure about that).

Again, thank you very, very much! I guess, I can exclude the monitor from the failure search now! ;o)

I wouldn't spend any money - yet. Do this:

1. Power off the PC
2. Connect over your Benq DVI cable to the PC
3. Power off the Benq - diconnect the power cable
4. Ensure the DVI cable is securely fastened to the Benq
5. Power on the Benq
6. Swicth the active input to DVI
7. Power on the PC

Does the BIOS POST or logo appear on the Benq or not? If it does, but not always, then you may have an unsolveable problem. What happens is this: when the video card is powered up, it checks each of its inputs for a plug-and-play monitor (with an EDID). The order varies from one card to another, but for all of them if there is nothing detected (no monitor found), they default to outputting on the analog VGA port.

So if sometimes it works, and sometimes it doesn't, you may having a timing issue - depending on how you see things, either the monitor doesn't respond fast enough, or the graphics card doesn't wait long enough. See what I mean?

This didn't work, but then I bought a very expensive DualLink-DVI-Cable and now it works.... everytime! I'm not sure, I'm happy about that, though, cause I couldn't really found the culprit.

Thanks again very much for your help, I guess I would have RMA'ed my graphics card again, otherwise.
And to get a bit more on-topic: your software seems to be great, too!

Dear Support

The DVI input on my BenQ FP241W suddenly stopped working a couple days back. The Monitor however works in VGA (D-Sub) input. I had the same problem as BC, "When I connect only the Benq via DVI-D, the display remains black except for "no signal detected", then the green light on the display turns amber."

I have tried using different DVI cables as well and plugging in the monitor to another computer. It still does not work in DVI mode.

I am currently using an LGE L1750SQ monitor in the first slot using an analog cable, I have my BenQ connected in the 2nd slot. (PS I have two video cards connected, I have disabled Crossfire for now, both monitors are connected to the first video card)

Could someone please help me in this matter? I tried to follow the steps given to BC however the Update EDID selection is grayed out!

You have a corrupt EDID header on your DVI port. There is no documented way to fix this unless Benq provides you one.

However, you may be able to work around this via the OS and registry - do a search on the web for "EDID override".

I've researched the EDID override process however, it seems that I am unable to go that route because:

1. Im assuming that using the OS to manually override the display driver may allow it in windows however it will not fix the monitor in DOS on boot?

2. The process of updating the display driver for the monitor cannot be done since the benq cannot even be recognised in windows in the device manager.

correct me if I'm wrong.

EDIT: Can't I just use Powerstrip to fix the EDID header?

I have the 'trial' version of powerstrip at the moment however it does not detect the BenQ at all.... just the LG
