I have to 4 standard bullet cctv cameras 2 are working to are not can it be in setting

Hello George Wolfe,

Absolutely... but only one way to find out (go commando).

I've got very impressed by a lady that was highly dissatisfied by the color presentation from her SWANN PTZ (smoked dome) many years ago...

Said she had attempted to work with TECHNICAL SUPPORT to adjust color but remained UNSATISFIED with the color...

She wrote on AMAZON... That she just went "COMMANDO"
and did it all herself and was really pleased with her results...
(Jealous... and still no idea what commando was).

Probably a decade later MY DARLING wife was trying to spin one of our cameras... and blacked out OUR front PTZ
(which has always had pretty drab color)...

Then the little darling WENT COMMANDO... (women are awesome smart)... Stepped into the set-up menu
mid set all the contrast, bright & colors... and tuned everything to exactly match the UN-SMOKED fixed focus cameras...

Long and the short of this STORY... I asked her how... she said one camera had a setting tab... the other had a gear-wheel. She clicked on that... and the rest was fined tuning CAMERA HISTORY.

Get into the settings of your "working" cameras...
Check out your settings (night & day)... THEN...
Takes notes and check out your "DARK" cameras.

If you cannot pull out a picture by re-setting these
basic camera settings: all to the mid-range... then tweeking the color settings until you are DELIGHTED with your picture

Take plenty of notes or scree shots to
TRACK YOUR CHANGES... If there is anything that is still working... this is the way to get them back.

Get yourself some NEW working cameras.

Basically its telling you to change to the correct resolution. You may have it set too high. If you go into "Safe Mode" you should be able to bring it down. Or if worse comes to worse, uninstall and reinstall your video card. Just make sure to have the drivers available.

LG studiworks CRT

The monitor needs to be repaired. The cost of the repair maybe too high. I suggest you get a quote first or gjust et a new LCD monitor.
Do not try to fix it yourself because there are high voltages inside these CRT monitors unless you understand display electronics and the dangers etc.

Pc desktop monitor

Here is what I would do. I would go into and reset the BIOS when you first turn on the computer.. If you don't know how , consider  disconnectng the power cord , openng the computer ,disconnect the battery for a minute, then reconnect it. That wil place the Computer back into the default settings which may put you back where you were. I believe that one may not set color settings to a higher setting that the computer and or OS can handle.

Blue tinted monitor screen

black and white tracking can vary in color depending on which color that the dispay is not getting enough of or to much of. In the case of it changing when you walk
in to the room, sugust that there is probably a loose connection or poor solder joint on the curicut board of the moniter. I don't suggust that you get inside the moniter and try to fix this due to dagerous voltage potential with in the moniter. Good luck

My Acer LCD AL1711 went off after seconds of turning on.

This monitor has "back lights" that are essentially like flourescent lights. These are high voltage lights and can easily fail. since you are getting some light initially, I would suspect a defective part that heats up a bit right away and then fails. I would try to replace the entire backlight board. This is the small board on the side (usually).
