I have Samtron 51s monitor bought in 2001, which has stopped working properly. When I switch on my monitor, colours and resolution are OK. But after some time it starts flickering, colours get all wrong, and images look like being taken using thermal scan.
Thank you.
I have exactly the same problem. It sometimes corrects itself after the monitor has been switched on for some time, but then reverts to its off colour mode. It seems to do it in vertical bars. At one time it had a red bar about 2/3 of the way across the screen. I changed all the electrolytic capcitors on the main board and on the PSU & it stopped doing that. Now it has pink streaks and wrong colours at full saturation.

It sounds like your video is set to the wrong resolution. Try booting into safe mode by pressing F12 at the start of the boot process. If you get into windows that way, then adjust the display to something you monitor can display like 1024x728@32bits. The monitor can only display a certain amount of pixels and if you set the video card to high you will lose visual. Hope this helps.
Check the data-cable between the computer and the monitor, and try a different cable.
Or, try connecting the monitor to a different computer, to see if the video-card in your computer is not working correctly.
If necessary, replace the video-card.
Colours on your monitor are produced by "mixing" the 3 "primary" colours: red/green/blue in various proportions.
Or, if part of the monitor that produces one of those 3 primary colours has stopped working, then the resulting "mix" will have too much RED/PINK. Fix/replace the monitor.
CRTs use 3 "guns" to mix the 3 "primary" colours (RED, BLUE, GREEN). One of the other guns has stopped working, leaving the RED gun as the "dominant" colour.
Spend $30, and buy a pre-owned 15" LCD monitor.
Or, spend $100, and buy a new 17" LCD monitor.
Not all DVRs have WORKING VGA output. I used to work for Nuvico, and we had 2 different versions for DVRs. Ones with VGA connection. The other with non-working VGA connection. VGA port itself does not guarantee.
Some DVRs also have DIP switch in the back.
You can simply toggle between composite or VGA output. Ones with DIP switches often require reboot, and from my experience these do not work well with VGA monitors.
Also... Make sure VGA monitor support low resolution. Stand-alone DVRs' native resolution is either 600 or 800 horizontal lines.
It will help alot if I know the model of DVR/CCTV
If it's still under warranty I would call for repair service.
It sounds like typical internal power supply trouble that needs electrical troubleshooting.
