brightness issue with Unico LCD Monitor

[HedgDog]

Hello, I am looking for some help, I recently purchased a Unico LCD monitor to replace my old CRT which is no longer working. I am getting a washed out picture and I don't know the next step. I have replaced the old Jamma harness, it is a MVS 1 slot Jamma board. I've adjusted the brightness, contrast, and everything else on the monitor. I have hooked up a Nintendo Switch through the HDMI and everything displays properly, also I have hooked up a computer through the VGA port and everything displays fine. Any help would be appreciated at this point, Everything looks good on the test screen, I get a Red, Blue, Green, and white. On the pics I have an image of the old monitor set up, and a picture of the Unico monitor hooked up, plus 2 pictures of the problem.

I was able to correct my problem by going through a RGB to VGA converter. I had no issues that way, but I can not correct the brightness going direct RGB through the back of the monitor. I hope this helps anyone who is planning on using one of these to replace an old monitor.
