I use this device from Aliexpress to position games on my CRT that are shifted when using the HAS:Most games look fantastic, but a few, such at Truxton (shifted to the left, cutting off the bottom of the screen) and Trio the Punch (cuts off all the info on the bottom) cut off portions of the screen that have useable info. These are the only games I played tonight, but it's not a huge deal, just wondering if there is a way to adjust screen position with the HAS or resolution being fed into a TV via RGB (SCART cable) into an RGT to component box.
I've had it for awhile now and it works great. I have an older PVM which you need to adjust pots on the inside of the case instead of a OSD. This is plug and play and I can now played Volfied perfectly centered which displays seriously downshifted with my HAS. Plus it helps with little tweaks here and there depending on the game. Hope this helps!
