As I had mentioned to someone on here, I had planned to do a review on this as I couldn't find much info on this TV. My only experience with Skyworth was a 15", clear 'prison' TV that I was given as a friend - was basic and okay, but had the essentials - decent sound, decent picture and decent input. Of the those three things, I would say that the G2A excels in 2 of the 3 areas.
In regards to the picture, it is simply impressive. The range of colors and contrast is truly impressive, rivaling Samsung and LG displays and far exceeding the Vizio e43 (2016, 4k series) that I had before, which only offered Dolby Vision - which, in my opinion, is an inferior standard as it's not well supported. What's interesting, is that the display came pre-configured to my liking - I'm not sure if these were maybe settings pulled from my Google Account, as I had used them on previous phones and tablets - like cool color temperature and a preference for the "vivid" picture setting, but they were pre-selected out of the box. In terms of overall settings, I would say that the choices are average - and for those of you wondering, yes, the Netflix App does detect the HDR and 4k support, and after the initial updating, 4k HDR video ran smoothly in Netflix and Youtube. However, during app updates, there was some stuttering at 4k.
As for the sound, this is probably the biggest surprise. Considering the price point of the TV, and what many budget brands - like Element and Haier sometimes offer, I wasn't expecting much - and was figuring that I'd eventually need to get a sound bar. Well, in this case, I think the sound bar can wait. The dynamic range of the speakers is impressive. The bass is loud and clear, as well as the mid range and treble sound. The 'virtual 3D' is quite impressive, allowing me to hear elements in music that I could not hear on my previous Vizio nor any of my other devices - except with the use of headphones. Like the display settings, the offerings for various sound options and emulated environments is pretty average. The TV does support DTS, but I have not found any information on whether or not the TV supports HDMI ARC - which leads into the one flaw of this TV.
The inputs are rather interesting. On one hand, the built in TV tuner - which supports ATSC and NTSC signals, is a nice touch. I was actually able to test my Atari 7800 on it, which, for resolutions of 160×240 and 320×240 over RF, was blurry but definitely playable once the display was adjusted to 4x3 as opposed to 16x9. This was a pleasant surprise as the Vizio I had would freak out at anything below 480i and lose the ability to display color if it was coming over composite - with no TV tuner, either, to work with. With that said, I haven't tested the channel feature because I live in the middle of a woods and I don't have a decent enough antenna (it's in the mail) to test with.
On the other hand, the choice of composite ports, instead of component with the ability to use composite, is a down side. While I do plan on having a composite mod done to my Atari 7800, I've taken up using clone consoles - like the Retron 5, in place of other consoles, and I managed to get a hold of an HDMI adapter for the GameCube, which has limited on my need for composite ports, in the first place. It's also a bit of an annoyance as I have an HD-DVD player, that I picked up with 70 movies for $50, a few years back that is limited to 1080i - making HDMI a bit of a waste. This is compounded by the fact that there are only 3 HDMI ports... and that these ports are rather strange.
HDMI 1 is capable of 4K, 60Hz and HDR. I was able to test this with my gaming PC, that I have in my living room. While I haven't played around with it too much, I did find that, in the Nvidia Control Panel (6GB GTX 1060 for those wondering), I wasn't able to get any of the custom color settings to stick, when adjusting for anything above 8bpp. I'm going to play around with this more, to see what I can get as the Vizio was able to do 4:2:2 at 12bpp. Needless to say, though, Assassins Creed Odyssey, at 4k, ~30FPS and medium settings, looked far better on this display than the aforementioned Vizio. As for input lag, I didn't notice much of anything while playing.
HDMI 2 is capable of 4k at 30Hz, and HDR support is unknown. I discovered this with the PC, so I have a Phillips DVD Recorder with an ATSC/NTSC tv tuner connected to this port, as I used this as a TV Tuner/DVR (and way of getting the Atari hooked up) to the Vizio when I lived in another town, where TV reception wasn't an issue. I'm not entirely sure what use this port would have to most people, except for maybe a 4k Blu-Ray player if they were using their HDMI 1 port for a PC or PS4 Pro or something like that.
HDMI 3 is probably the biggest WTF as it is limited to 1080p. This is the port where I have connected my HDMI splitter to, that hosts my GameCube, Switch and Retron 5, as these are 480p, 1080p and 720p devices, respectively. Because I used the 4th port on my Vizio for the Wii U, I'm going to need to look at a larger splitter.
And finally, Android TV itself - the apps are a nice feature, though, as mentioned before, app updates can affect the performance of Video Playback. I haven't tried any of the games yet, but I find it a bit comical that emulators are at the top of the list. Two games did come installed on the TV, and by default, roughly 10GB of space, out of a theoretical 16GB, is left available for User Apps. I haven't tried to see if a USB flash drive would allow for more space - I'll have to get back to that. However, most streaming apps are not that big. The TV does run Android 8 and Skyworth is claiming that they'll update the TV through Android 10 - time will tell if this is true or not. As for the setup, it was a bit of a pain as the TV did not have you connect to a network as a first step. Now, if you were to use the Ethernet port, this wouldn't be an issue. But if you're using WiFi, you'll want to select the manual setup over the option to setup the TV based on another Android device.
As for build quality, the TV seems to be well made, but it is wobbly. For this reason, straps and a wall mount are included in the box as well as numerous warnings of the possibility of the TV falling on a toddler, if they push on it. I have not used any of this yet, but I'll probably screw two eye hole screws into the wall and use the straps to prevent any accidents.
If there were things I could change, it would be upgrading the composite ports to component, making all of the HDMI ports equivalent to what the HDMI 1 port offers and adding an additional port or two. I would also like to see at least 32GB of storage as a default, if not 64GB. And A72 ARM cores, in place of the A53 cores, would probably resolve the slowness during app updates.
Otherwise, I'd score the TV as a 8.5/10.
Edit - I was able to get 12bpp using Chroma 4:2:2 on the PC. Not sure why the setting wasn't taking hold at first. But HDMI 1 is HDMI 2.0 compliant, which means that 12bpp at Chroma 4:4:4 isn't possible, unless the frequency is reduced to 30Hz - so a specification issue, not an issue with the TV.
