Thread: Dynamix LCD "no input signal"

Firstly, what are the parameters of the drive of the new mobo?
Resolution, frequency, color depth, refresh rate, etc.
You can make it display on the screen from the menu.

So, the old mobo was able to display pictures on the car monitor.
Please attach another LCD monitor to the old mobo and ask about the same signal parameters as mentioned.

Compare them.

Identical: you have right, there is something wrong about the signal. You need some electronics.
Non-Identical: I have right and there is something about the settings of the display, you just need to set the parameters.

it just sounds like the output of the new mobo is a resolution the screen cant handle, plug in your new mobo to a monitor that works, set the resolution really low, like 800x600 (lower if you can). re-attach it and see what happens

Unfortunately I sold the old mobo some time ago so I can't compare the old mobo vga setting with the new one.

Anyway, the car's lcd monitor (dynamix) works correctly with the vga output of my notebook and I can correctly expand my notebook desktop on the dynamix monitor. Can you please suggest me on where I can see the parameters are you mentioning?

I have just made some other test today connecting my crt monitor to the new mobo; I entered the bios and tried some random editing on "video function configuration". On every change I saved and rebooted and the crt always worked with apparently no changes in displaying the image; then I've connected the dynamix getting always the same boring message "no vga signal"

I've found a lot of settings in the bios, mostly unknown to me. FYI here's the group I've wrote down:

- boots graphic adapter priority {IGD, PEG/IGD, PEG/PCI, PCI/PEG, PCI/IGD}
- internal graphic mode select {DISABLED, ENABLED 1MB, ENABLED 8MB}
- aperture size select {128MB, 256MB}
- video function configuration
-- DVMT mode select {Fixed, DVMT, combo}
-- Boot display device {AUTO, CRT, TV, LVDS, CRT & LVDS}
-- Flat panel type {640x480 LVDS, 800x600 LVDS, 1024x768 LVDS, 1280x1024 LVDS, 1400x1050 LVDS, 1400x1050 REDUCED LVDS, 1400x1050 NON REDUCED, 1600x1200 LVDS}
-- Local flat panel scaling {AUTO, FORCED, DISABLED}

As I said, I've already tried vorious combination with no result; crt monitor always works good but dynamic lcd always stays on "no vga signal" message.

I hope you can help me to solve this issue!

P.S. You can see the dynamix monitor I own here: http://cgi.ebay.com/Dynamix-WideScre...QQcmdZViewItem

These BIOS settings are not affecting VGA signals.

Double right click on desktop. Properties/ settings/ resolution or color depth

It does not give any symptom of life during POST? Try it. Connect the car lcd before powering on.

No symptom of life during POST nor during OS loading. With the dynamix I'm totally unable to see anything. As already said it works well with my notebook VGA output, and it worked good for months with my old mobo (with integrated graphics too).
I'm suspecting it's a intel drivers problem.
Today I've connected the mobo to my 22" lcd home monitor and noticed that there's no problem during post and OS loading; I can see the image as expected. When the OS is loaded then the image disappear and my 22" goes to standby; really strange behaviour!
Mobo works without issues with CRT monitor, any resolution/color depth combination.
Anyway, I've read of someone using xenarc lcd monitor successfully with my identical mobo so, it's clear, it's some kind of incompatibility between vpower mobo (maybe intel 915gm chipset) and dynamix lcd monitor.

I tried also to install an old free version of powerstrip; it detect correctly bot video chipset and philips crt monitor but when I disconnect CRT, connect dynamics lcd and rescan, it says it's unable to communicate with the monitor

I'm really frustrated by this situation

Really, I'm going to change the mobo.... or maybe the lcd??? Moreover it's difficult to find these items here so I always buy from usa (sometimes china) and this complicates all

Well, in this case the root of the problem must be electronical.
I also think, you have to exchange a component.

Is there any refresh of the bios? What did the manufacturer of the mobo say?

I'm trying to contact the seller idotpc.com. I think it's a video issue of the i915 chipset; in fact it seems to function correctly only with a crt monitor connected. Yesterday tried my 22" pakard bell and today I tried another lcd (21" from fujitsu-siemens) with no success so my suspects now are fully on the mobo integrated video card, the i915GM chipset but I'm unable to solve the problems that I have. Do you have some advice on this?

Unfortunately, not. I think you have to wait for the result of the contact with manufacturer...

I'll wait. Thanks a lot for your help
