LCD monitor displays in monochrome

[Kijana]

Hi guys, I have an old cpu, HP Compaq dc7700 sff that is displaying in monochrome. I have tested several monitors, therefore I think the problem is with my cpu. I don't have a gpu card.

Thanks.

Hi, thanks. I have seen this answer.

My monitor is not displaying in black and white, it looks greenish. I have even tried reinstalling different versions of Windows, but it can't get right. I also don't have a dedicated graphics card.

If your monitor works properly with another system, then I would think that the problem is with the video portion of your motherboard. Unusual problem.

I believe in cleaning as the first step to solving any problem... a bit of corrosion or a broken solder joint on a connector can interfere with transmission of color - for VGA connector pin 1 and pin 6 carry red signal - so inspect your connectors carefully under strong light and magnification.

Try with a different cable between the PC and monitor. If no improvement Cycloid is most likely correct in which case you may want to buy a new computer.

Hi guys.
I found the problem was with connection of the feet to the motherboard.

Thanks a lot guys.

Hi guys. I really appreciate the help you gave me. I have learnt a vital lesson.

Unfortunately, am not good at soldering and such, so I'll look for a budget graphics card - maybe secondhand and go on.

Good thinking. Be careful to check that whatever card you choose will fit in the space available inside the case.
