Safe mode problem

Tasocahtfu · 20 May 2006 at 17:15

I've just bought a Samsung 26" LCD TV which I'm also using as my computer monitor.

When I boot my computer into Safe Mode, the TV comes up saying unsupported mode? I run the TV in its native res of 1360 x 768 normally, but shouldn't safe mode just load up as normal?

Anyone have any ideas?

Thanks a lot

Dont know for certain, but I would possibly assume that the default windows driver for your GFX card doesnt support that res.

Read the TV manual, what modes does it support ?
Safe mode is 640x480 if I remember.

Yup I checked the manual, that's why i'm a bit confused as it says it supports 640 x 480 and I didn't think safe mode would be any lower than that :confused:

bit of a long shot really but are you running it on the DVI output? might be the safe mode drivers dont support that output only the VGA one!

No fraid not, connecting the PC via a HDMI > DVI converter (the TV only has HDMI, not DVI) throws up all sorts of problems according to the thread about it in the Home Cinema part of the forum, so I only run it off the VGA.

Don't understand it :mad:

What about the refresh rate.
In safe mode it drops to a low 'compatible' figure.
Or the driver disables the TV out?
It the TV detected normally as a TV or a proper display ?

The manual says that in 640 x 480 the supported refresh rate is 59.940, so would this be why there is a problem? Because the monitor is set to 60Hz and safe mode drops below it?

The TV is detected in windows as just a Plug and play monitor by the way.

I just removed the Nvidia drivers to see if it would cause the same problem in normal mode and it does. Once I rebooted the screen would not display the windows logon screen, so it must be down to the fact that the default windows driver doesn't display at 60Hz, would this be correct?

If so, does anyone know if it is possible to force it to do so? I had to connect up my old monitor just to reinstall the new drivers, seems ridiculous that I'd have to keep another monitor around just to do that?

You're using a device that isn't a PC monitor as one, why is it so rediculous that Windows doesn't have it's display modes stored as defaults? Just keep a spare monitor around for when things go **** up.

I didn't say it was ridiculous that they aren't stored as defaults, I was implying it's ridiculous that there is not a way around it without having to keep a spare monitor nearby. I suppose I expected that as a fair amount of people use these screens as PC monitors as well as a TV that the manufacturer would have done something to get round it. But if that isn't possible then so be it.

Try and find the registry entry for the 640x480 safe mode resolution and alter it's default refresh rate to something that works. This will NOT be the driver for your video card but the standard Windows VGA one.

Thanks mate I'll look into it

ns400r · 21 May 2006 at 20:57

Can't be too hard to work out. If it were mine then I'd spend a little more time finding how to do it, but it's not so you'll have the honour.

From what I can tell, the TV wants 640x480 @ 72Hz.
