This is my first post around here, so forgive me if I say anything that's wrong. Please, indulge my ignorance.
First of all, I am trying to build a retro-room. Well, a video game room actually. What would it have? Consoles, TVs and speakers. Easy, isn't it? Not that much, actually...
I assume I have many errors, misconceptions, etc. Please, don't be rude, just try to explain what is a mistake and I'll try to understand
1. Help me with TVs
I want to have the following systems inside my new VG room: Atari 2600, NES, Top-Loader NES (NTSC), SNES, MegaDrive, Saturn, Nintendo 64, Dreamcast, PlayStation 2, GameCube, Xbox, Xbox 360, PlayStation 3, Wii, PlayStation 4, Xbox One, Wii U, NES mini and Nintendo Switch. Also, a PC and a MAME-dedicated small PC I want to build.
I would assume that the most logical choice would be splitting those systems into two different groups:
a) CRT group — Atari 2600, NES, Top-Loader, SNES, MegaDrive, Saturn, Nintendo 64, Dreamcast, PlayStation 2, GameCube, Xbox, Wii, MAME-PC.
b) HDTV group — Xbox 360, PlayStation 3, Xbox One, PlayStation 4, Wii U, NES mini, Nintendo Switch, PC.
1.a Which is the best CRT for me?
All these consoles can handle RGB (some of them require modding), so this CRT TV should be compatible with RGB. These use three standard resolutions: 240p, 480p and 720p (some Xbox games). Also, there are two main aspect ratio standards: 4:3 and 16:9. As I'm European, I would like to be able to play in both PAL and NTSC and also in both 50Hz and 60Hz.
Another interesting option I would like to consider is that I can rotate it in order to play vertical top-down shmups. Many of them use a 9:16 aspect ratio, so it would be interesting if I can take a CRT that can handle RGB, these resolutions (240p, 480p, 720p), these aspect ratios (4:3, 16:9), these standards (PAL, NTSC) and these refresh rates (50Hz, 60Hz) and that can be easily rotated.
1.b Which is the best HDTV for me?
I think this is quite easier. These systems use three standards: 720p, 1080p and 4K. So a 4K TV would do the job, since 4K is 720p × 3 and 1080p × 2. Apart from resolution, refresh rate should be variable and as high as possible. I think it would be better to wait a year until we see displays that uses the advantages of HDMI 2.1.
That would mean that I could play perfect both Xbox 360/PlayStation 3 that used 720p30 standards and PC beasts such as Overwatch, which I could run it at 1080p144 or even higher.
Another important thing is that the TV should have lowest input lag as possible. Many alleged "high-end" TVs are actually crappy when talking about lag. Problem is I want it to be as big as I can, since it is going to be my girlfriend's TV for cinema to and, as such, our main TV.
So, in other words, I want an HDTV with 4K, variable refresh rate, high refresh rate, HDMI 2.1 input, > 50″, lowest input lag possible. The TV I'm looking for does not exist... YET. But it would eventually be made, wouldn't it?
2. Help me with audio
Consoles handle many different audio codecs. Although it actually depends on the game, consoles use to have a specific Dolby codec that makes it easier to get good 5.1 sound. I would like to find a solution for this problem: which would be the best AVR and Home-Theatre for these systems?
I elaborated a list of systems according to their audio capabilities. Please, do note that this depends on the specific game, so this is just a general list of basic information.
a) Mono — Atari 2600, NES, Top-Loader, NES mini
b) Stereo — MegaDrive, SNES, Saturn, Nintendo 64, Dreamcast, MAME-PC
c) Dolby ProLogic II and/or Dolby Digital — PlayStation 2, GameCube, Xbox, Wii
d) Dolby TrueHD — Xbox 360, PlayStation 3, Xbox One, PlayStation 4, PC
e) Dolby Atmos — Depends on the game, but currently just a couple of PS4/PC games can handle this standard
f) Linear PCM — Wii U, Nintendo Switch
So, in order to build up a 5.1.2 setup, which would be a good option? Note that I cannot afford a +€10,000 device.
The idea is I can switch easily between mono, stereo, 5.1 and Atmos without any problem.
Thank you very much!
