Display settings lost on reboot

doveman · Mar 30, 2009, 04:20 PM

I've been trying to help my friend who has a PC with an 740XL card. I've installed the latest driver and CCC and I can set it up so that his CRT is the primary display and his LCD displays the desktop in Clone mode but after rebooting, it resets to just the CRT and I have to re-enable Clone mode again.

I'm sure it shouldn't be forgetting the setting like this and he finds it rather annoying, so I'd appreciate any help working out how to get it to stick.

First up, welcome to the forums.

I can't say for sure what's wrong as I haven't come across this myself, but I have seen something similar where it will always clone to both displays on reboot even though it was set to extended beforehand, or where it will always chose the other display as the default, and not show anything on the other one. If I had to guess to what's happening in your case I'd say that it's probably that the graphics card (or rather CCC) is not automatically detecting one of the displays (in this case the LCD), probably due to a timing issue, and since it doesn't see it Windows defaults to single display mode. I do have a couple questions and suggestions though:

1) Try reversing the monitors, making the LCD the primary, and the CRT the secondary. If it holds it could be a matter of the driver detecting

2) Try switching the headers on the video card that the monitors use. So, if the CRT is on the header closest to the top, switch it around so it uses the other, and vice versa for the LCD.

3) Try changing the way the CCC handles detection of monitors, and how it outputs DVI signals. If you have any of the monitors hooked up by DVI there are 2 specific options to try changing which will be under the Digital DVI listing: "Reduce DVI frequency..", and the other is "Alternative DVI timings". By default the latter one is on.

4) How do you have the LCD hooked up? Via the older VGA D-Sub, or by DVI directly? Also, does either monitor have multiple connectors, such supporting both DVI and VGA D-Sub, and if so, does it automatically cycle between them when the PC is turned off/rebooting? I know in the case of Samsung their monitors will cycle the connectors whenever a signal is lost until it finds a signal again. This can cause the system to think that it's disable when it reboots if that monitor is the secondary one. To overcome this you have to change a setting in the monitor so that it always stays on whatever connector you are using (with Samsung it's just a matter of chainging "Auto Source" to "Manual" from it's default of "Auto").

Hi Tipstaff, thanks for the welcome and the tips.

I'll have to check but the TV is a 32" LG which I believe's got 2 * HDMI and a D-SUB and I think the PC's hooked up to HDMI-1 with a DVI-HDMI lead. The CRT monitor's definitely D-SUB only. I don't recall the TV cycling through the inputs, I think it stays on HDMI-1 and shows "No signal".

In this case, it sounds like tip 3 might be worth trying first so I'll give that a go and then try the others if that doesn't help. I'll let you know how I get on.

Ahh... I'm glad you clarified that it's an LCD TV. TVs have issues of their own when it comes to dual output. Some TVs have to be on before you turn the computer on for it to be detected by the video card, while some have to be turned on after the computer is up and running, in which case you will always have to setup dual output each time you startup your computer.

Of note, there is a section in the CCC that deals with HD TVs that you should look into that includes options about forcing the dection of HD TVs.

Yeah, sorry I didn't make that clear in my first post.

You're right about TV's being strange. I'm currently running a Nvidia card (but planning on getting a 4850 for my new PC, so expect to see more of me around here

) into my CRT HDTV via DVI and it remembers the settings even if I unplug the TV from the wall but not if the DVI cable is disconnected at either end!

Thanks for the tip about the HDTV section of CCC, I'll take a look at that.

One thing to try would be saving the settings you need as a profile in the CCC, however, save the profile as "Default". The CCC will always load the default profile no matter how many you have, or what your last used profile was, so by saving your custom settings as the "Default" profile it will always load that when Windows starts.

I don't know if it's going to work in your situation, but it's worth a shot.

Thanks, I didn't think to try that. I set up a "Clone" profile that he can select from the taskbar icon, which makes things a bit easier than having to go into the settings each time, but if the "Default" profile will remember the Clone setting that would be perfect.
