LCD monitor goes off and on but only in DOS

I just acquired an almost new Samsung 914v LCD monitor. In Windows it works great, but I've been booting in DOS a lot lately trying to fix some hard drive problems. In DOS the image goes black every 5-10 seconds, stays black for a second or two, then comes back on and then goes black again. Does anyone know what to make of this? Please let me know if you do.

I'd just have to take a SWAG at it. (Scientificwildassedguess)

LCD monitors DO NOT natively have a 640x480 (VGA/CGA) resolution.
They are meant to accommodate the higher resolutions of today's PC's.
That it even works at all, is a miracle.

My Envision 19" LCD does work fine in DOS, but it's also one of the last that still use the standard aspect ratio of the CRT's. (It's NOT a wide screen)
I guess it just depends on how the engineers designed it.

If you have NO settings on the monitor itself, like an Auto Adjust mode, (look for that) you may just be S.O.L. (you know what that means, right?)

I'm glad to hear that I'm not the last one on this planet using DOS.
Do you have/use NTFS4DOS? I find it irreplaceable when trying to access files on an NTFS drive, from DOS.
If you'd like to compare notes on DOS, drop me a PM.

Cheers mate!
