I can not do the VR thing, makes me kinda wanna hurl. I do have an eye issue as well and the strobing doesnt do it good.
Once you use 4K, 1080 is so hard to go back to unless you use a 32 inch or lower main screen.
I alsways use actual pinball cabinets, if you build a cab from scratch unless you use a standard size you wont get a lockdown bar. Every home made lockdown bar looks awful too.
These days you need an 8GB GTX1070 MINIMUM for 4K, and the settings will have to be lowered. I also use Philips monitors - the 40 inch once fits into a standard cab, and the 43 inch fits into a wdebody cab without decasing.
If you decase the screen then you are handing something very delicate everytime you take it out the cab.
Also do not mount the PF monitor against the PF glass. You need to set it down to allow airflow. Otherwise it simply wont last.
Use 12v starter solenoids for feedback, contactors were an absolute letdown when I have used them.
Do not forget COOLING in the main cab. It needs fans and circulation.
Use a pinscape board for digitial plunger/buttons etc. KL25Zs are hard to get but they are due in soon.
Having probably built more than 20 cabs now, quite a few owned by people on this group (a couple admit to it - most do not.......)
Yes - I do build for profit !! ! ! Shame on me! I agree, you can make them yourself, but it will take time.
Setting up the cab with software I do in a few hours, as I have hard drives ready to go with the files. You try downloading loads of games, PUP packs and backglasses. Plus all the roms....
My advice also would be to go for an actual PC monitor for the DMD and not a pin2dmd. These are more valuable for real pins - and in the near future when Spike 2 emulation gets releasted, you will need an LCD screen...... Plus Pin2dmds look rubbish when playing say a baywatch which uses a larger DMD. It does compress it but it is not great.
The things I would not skimp on is:
Graphic card - GTX2070 8gb or better ideally for 4K, 1080 a 1050TI 4gb is useable. i5/i7 processor. 8gb min RAM (I now use 16gb on 4K builds).
PC power supply - use a high wattage! Your graphic card again needs decent power.
Use extrernal PSU for all the solenoids, amps, other screens. Nowadays I use a 12v 30a PSU.
I also wire everything 230v thru an solid state relay so everything gets turned on and off with the power button. When windows shuts down - the power to the screens/PSU etc also gets killed.
Most people run PUP PACKS which makes DMD games look like a JJP game. Got a few examples on my youtube channel.....
I use Pinball X selection but the standard is now PINUP I just dont like it and I would have to spend ages converting my config files.
ALTSOUND packages emulate PINSOUND.
ALTCOLOUR packages emulate pin2dmd colourisation.
- this is my youtube channel - full of rubbish but you may find something useful.
