1) Did you adjust the monitor colour settings? Old monitors
allow you to change the colour accordingly. If there is too much
red, it would look reddish. Too much green would be greenish. Too
much blue would be bluish. Too much of red and green would appear
yellow. Too much of red and blue would be purple. Too much of green
and blue becomes cyan. If it's balanced, it would be white in
colour.
2) As for the flicks, it could be the refresh rate. Old monitors
have to refresh constantly and it normally would return to normal
after a while.
3) Press the Zoom button on the monitor to adjust it to 0 or as you
deem fit.
4) You probably don't have enough RAM, that's why your system is
lagging. Don't run too many programs at one time. If you are not
using it, close the programs. Open it when you need it.
If your monitor is spoilt, it would flicker every few seconds and
give you some funny sizes. For example, this moment it fits your
monitor, next moment too small to be seen, another moment later it
would too big for your monitor. A temporary cure to it is to adjust
your screen size as small as possible, by using the buttons on the
monitor. It would last you for a while, but not long. A few days
later, the problem would return.
Spoilt TV ask repair man to repair TV, I don't know how to repair
TV.
