Widescreen Gaming Forum

Followed the instructions on the website and the new resolutions aren't showing up like they should. I have an ATI HD 4870, so they should be supported.

1440x900 shows up in the dual head section, but not in the triple head section of the Powerdesk software. I have updated the firmware and software exactly as the instructions stated. Help?


Thanks


Uninstalling and reinstalling the Powerdesk software had no effect. If I have the correct firmware and correct software, why wouldn't they show up? On the troubleshooting information screen, it shows "Matrox Cable: Detected" And "Dual-Link DVI Support: Yes". I am using the cable that came with the TH2G.

Thanks again.

I don't know what to say ... mine worked just fine apart from not getting the single screen res of 1920x1200.
I can live without that ... it is no big deal for me.

EDIT ... maybe your issue is an ATI one ... I take it you have the latest ATI drivers ?
Edit #2 ... when you did the firmware update did everything appear to go Ok ?

I don't think reinstalling just the PowerDesk software would be enough.
Did you backup the previous firmware ?
Maybe you should go back to that backup and try again ?

I am not too sure about the 4870's compatibility with the new firmware as the card might be just too new.

Notice this in the footnote of the firmware download page:
1 Available only with certain NVIDIA® (triple 1440x900 at 60Hz and 1680x1050 at 57Hz) and ATI™ (triple 1440x900 at 60Hz) GPUs.

I wonder why ATI only goes up to triple 1440 x 900 while Nvidia cards can go up to 1680 x 1050 ? Nvidia has better drivers?

Hmm, maybe the 4870 isn't tagged as supported because of how new it is. I had an 8800gts but it died a week or two ago, so I got a 4870. My 19" LCDs are 1440x900 native, so that's all I really need.

I do have the latest ATI drivers. I also backed up the old firmware. I'm not really sure what putting the old firmware back on and then reinstalling the new one would accomplish, but I'll give it a shot. I didn't get any errors throughout the process, either. Everything went smoothly, the new resolutions just aren't available for me to choose.

I should also mention that I am running Vista Ultimate 32-bit in case that matters. I'm still running in 3x1280x800 for the time being :(

For my sanity's sake, has anyone gotten this working with an HD 4870?


Thanks

At Matrox site, their GXM Compatibility test shows that ATI HD 4000 series should support the new resolution of 3 x 1440 x 900.

Yeah, the compatibility tool shows 3x1440x900 as my max supported, but the Powerdesk software won't show that as a selectable resolution. I've tried everything I can think of at this point. Reinstalling firmwares, reinstalling software, hacking the registry, using custom monitor inf drivers from Powerstrip... nothing works. I just don't get it.

Ok, I have a 3870x2 and had the EXACT same problem, but I fixed it.
When I first got my TH2GO I had this same problem, just with different resolutions. It would only show standard res and not widescreen.
So I just went through the same steps as I did before and all is well!

1. Uninstall all matrox software. Reboot if it asks you to before going to the next step.

2. While leaving your computer on, unplug your TH2GO from the usb and the DVI port going to your computers gfx card.

3. Then plug in the monitor of your choice directly into your computers gfx card, bypassing the TH2GO. Your screen should be working now(after it makes the usb DING sound).

4. Uninstall all ATI software through the uninstall utility in Control Panel and Reboot.

5. Install the video card drivers and reboot.

6. Once it's rebooted, check in the display properties to see if the correct monitor driver is installed. If it is not, install and reboot if necessary.

7. With the computer still on, unplug your monitor from your gfx card and setup your TH2GO like you had it at first(with all 3 screens plugged into the TH2GO and the TH2GO plugged into the GFX card).

8. Install the GXM drivers and reboot.

Note that the correct modes won't be listed in the GXM software(at least mine weren't) but it IS availible in the desktop properties. Hope yours works after trying this.

Ok, I have a 3870x2 and had the EXACT same problem, but I fixed it.

Thanks, I'll give this a try tomorrow.
