I have those AV2HDMI converter a lot for FPV laptop viewing, however it will not fix blue screen issues most of the time because of the characteristic of LCD screen frequency which might not sync properly with FPV video, i've had same issue once. Best is to replace the screen and buy a proper FPV goggle to save up money and time for long term solution. I had a friend cut corner using this method and he fail at FPV. There a lot of FPV goggle around the market under EACHINE brand that costs same as oppose to fixing the blue screen issue.
