LG's 48-inch OLED Gaming TV with G-SYNC Goes on Sale This Month

LG is preparing to launch its latest addition to the gaming lineup of panels and this time it goes big. Preparing to launch this month is LG's 48-inch OLED Gaming TV with 120 HZ refreshing and G-SYNC support. To round up the impressive feature set, LG has priced this panel at $1499, which is a pricey but a tempting buy. Featuring 1 ms response time and low input lag, the 48CX TV is designed for gaming and fits into NVIDIA's Big Format Gaming Display (BFGD) philosophy. Interestingly, the TV uses LG's a9 Gen3 AI processor which does content upscaling so everything can look nice and crisp. Ai is used to "authentically upscale lower resolution content, translating the source to 4K's 8.3+ million pixels. The technology is so good, you might mistake non-4K for true 4K"

As a Rtx 2080Ti owner and a 4k TV owner , I can honestly say anything over 4k 80hz is kinda a waste , so 4k 120 hz is nice but you wont get a modern 4k game near 120fps unless you go with lowest graphics and that kinda defies the point of 4k gaming in my mind.

Older games most definitely !

With the new Ampere and Big Navi cards launching around the same timeframe, I'd expect 4K 120Hz to be achieveable in this generation of GPUs. If not this product is futureproofing for the next.

What about esports games and the like (i.e. the ones that benefit the most from high frame rates too)? I would be surprised if a 2080 Ti couldn't do 4k120 high/ultra in Rocket League or Overwatch.

There's also the option for running dynamic resolution scaling for games where frame rates are more important than visuals.

I mean these tvs are already excellent as monitors, if you obey said work arounds. They support chroma 444, VRR, lfc, all that good stuff.
Too bad they're too large for a desk then ;)
But yes, this year's crop is built for the upcoming consoles and they do tick pretty much anything you'd want from a monitor.

The taskbar can be set to auto hide, and if a person's use is such that they are looking at the same menu/hud for 50+% of their content they probably don't need OLED anyway. "Regular" use for most people is highly varied content.
Still, I know very few people that don't find an auto-hiding taskbar annoying. It makes a simple mouse click take ~3x as long because of the wait for it to pop back up. And as "highly varied content" people may be using, if you're not going full screen, the taskbar (and the menus will still be there). On the other hand, if you're into HDR photography or mastering some movies, you won't care much if the monitor suffers from burn-in in a year; by then it would have already paid for itself :D

I do on a daily basis, did it with Plasma for years too. It's fine with some viewing habit changes. But that alone requires a change in user behavior, so it's not for everyone.
All of the old plasmas at work had the task bar burned into them. Was one of your viewing habit changes to auto-hide the taskbar?

If LG is so confident I will not get burn in, how long does their burn in warranty last? 3 years, 5? or is it only 6 months to 1 year?

First, this is not about how confident LG is, is about how the handful of here on this forum are in using OLED for a monitor.
Second, there is no such thing as "burn in warranty". LG lumps all their TV under a 1 year warranty (with an option for buying extended warranty, of course).

Third, I gave up on Ubuntu. Too many old packages in there for my needs :P

playing PS5 games on it in 12 hour binge sessions in games with HUDS is not different than using it as a monitor, so the fact LG doesn't advertise this for movies only is a bit misleading then. 1 year warranty for such a pricey item does not show much confidence imo, I think I will wait for new QLED in a year or so myself.

I think the 55" 8K coming in a few months might be even more glorius, especially for computer use as there will be almost 0 chance of burn in and even at 55"s the DPI will be rather nice.

It's got a couple of tricks it runs automatically to fight burn-in. Plus another one that you can run on demand.
That one year is really just a starting point. Electronics that do not fail within a year, tend to run till something physically breaks.

QLED/NanoCell/Triluminos offers about the same color gamut, better brightness, but until microLED kicks in, all incarnations suffer from idiotic FALD implementation (i.e. few zones, blooming galore). And considering how much FALD models cost, microLED variants will probably cost more than OLED :(

On top of that, the better (yet still inadequate) FALDs get really hot. Their power consumption, especially viewing HDR content is silly. My edge-lit 65" HDR TV uses 125W peak, Both the current Vizio Quantum P and Sony Triluminos 384-zone models use 328W and 315W respectively. Those aren't peak values, they are typical values.

maybe I will just risk the LG OLED 48" after all. yolo and all that

Actually it's not that bad for what it is and versus other (and larger) 8k ones, e.g. Samsung, cheaper than some of the "gaming" (UHD or ultra wide) montors being touted at the moment.

Around €2,200.

I think the OLED being discussed is around 1500, so given 4x the number of pixels and probably the full 48Gbps HDMI 2.1 versus the likely gimped to 40 of the UHD one, the 8k looks like better value. It will do 8k/60 too ... so you can have 8k/60 for desktop and a lot of space and switch to 4k/120 (possibly with upscaling) for gaming but still have the benefit of a better DPI.

It can easily double as a really nice TV too. ;)

A pity it's not out until late September so we could see some reviews.

Are you sure it will support 4k120?

Yes, the spec says 8k60 and 4k120 "HFR". Whether it will do those at 12-bit is another matter but I think it's more likely to have "full" HDMI 2.1 than the 2020 4k models.

@bug, I think that's only for 4:2:0 SDR, if you go to 4:4:4 and add HDR it goes up a lot from there.

According to this: en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_standard_video
4k@120Hz only needs a little under 26Gbps.
a) I was asking about that specific TV, not the interface, and
b) that comes with some asterisks added:
Wikipedia
Uncompressed 10 bpc (30 bit/px) color depth with RGB or Y′CBCR 4:4:4 color format and CVT-R2 timing are used to calculate these data rates. Uncompressed data rate for RGB images in bits per second is calculated as bits per pixel × pixels per frame × frames per second. Pixels per frame includes blanking intervals as defined by CVT-R2.
@nemesis.ie That just leaves the issue that 55" is entirely unusable as a monitor - you'd either need to sit so far back you would need to lower the resolution, or you would at the most be able to see ~¼ of the monitor comfortably. It is essentially a 2*2 grid of 27" monitors after all, so while the lower half would be great as a dual monitor replacement, the upper half would be of no use to anyone but your chiropractor.

I'm on a similar page, my thinking is this, at a little further back, you can effectively have the same area "in use" as e.g. my current 32" monitor but at a much better DPI, so for regular use, you can still work with your window of interest and be no worse off, you can then have other things sitting on the other parts of the screen as if you have 4 monitors in a 2 x 2 grid, as you also mentioned.

Items you just need to glance at could be on the top, system monitoring etc.

For gaming, you can then either get a very immersive experience if your card can drive the detail well, or, as you say, sit further back.

So it may not be as bad as e.g. a 43" UHD screen as it is usable close up due to the detail and allows moving further back due to the size.

I'm also considering it could be put on a shelf a bit lower than a desk in front of it such that you look more at the centre, this would need to be height adjustable to move it out of the way when using it at a distance, but this could be the ultimate setup if you had e.g. two electrically height adjustable desks and you raise the front one for close use with the back one lowered and then swap them around for using them from a distance.

You could also use it in ultra-wide, if the scaling/GPU allows it, just using 1/2 the screen in a horizontal format and it would still be price-comparable with some of the high-end monitors.

I might give one a go in September and see how it works. ;)

I fail to see your problem. There's enough bandwidth there for uncompressed, 10bit per channel, 4k, 120Hz. And then some. Are you worried the CX has missing bandwidth or what?

I don't think I've ever seen anyone suggest using an electric sit-stand desk as just a monitor stand before :D But yeah, it could obviously be doable with enough space (and money :rolleyes:), though one would also need to account for differences in eyesight - most people read the best at 1m distance or below, not just due to text sizes but also the focal properties of our eyes (detail perception being the best at relatively close ranges even for features where their perceived size is the same) so reading text on a huge monitor further away might be problematic still. Nearsighted people would definitely struggle!

The mock-ultrawide use case is interesting, though I think that would necessitate some sort of background color matching on the rest of the panel - those huge black bars would definitely affect the experience (and possibly give the impression that the monitor is about to tip over and hit your head :p). Could still be a great experience though.

For the "very immersive experience" gaming use case you sadly would get the same issue as poorly implemented ultrawide support: having to sharply turn your head to see basic UI elements like ammo counters or health bars. If that was fixed it would undoubtedly be cool, but if not, IMO that would hurt immersion rather than increase it.

I think the Tl;dr here is that there sadly is no such thing as an ultimate monitor - there will always be something that could be improved.

Jesus, can you please actually read my post? I was specifically asking about the upcoming 8k panel @nemesis.ie was talking about. My question had nothing at all to do with the CX, nor its bandwidth. I was not asking about bandwidth, but whether a TV - which after all includes not only an interface, but a processor, display driver, display panel, etc. - was actually capable of displaying 4k120. Just because 8k60 necessitates more than sufficient interface bandwidth for transferring an 4k120 signal does not mean that the rest of the parts of the TV are capable of actually displaying this. And just because the 4k CX series supports 4k120 that doesn't tell us whether an 8k60 panel from the same manufacturer would be capable of displaying 4k120. Okay? Can we please abandon this stupid offshoot of this discussion now?

I'm all too familiar with visual acuity, I've another eye surgery in 10 days. :(

I think the big thing with the monitor I'm talking about (not the one in the topic) is the 8k resolution, the improved DPI makes it more like a phone to look at at e.g. 0.5m distance. It would actually enable those with worse vision to move a little further back and probably have text nicely displayed.

I think black top/bottom bars might be less of an issue given how tiny the bezels are versus the size of trhe screen. But maybe matching the wall-paper/paint would work, Samsung's TVs do that for when they are idle if you wish so they "vanish" although I think I'd prefer the option to display art/photos if a large black space bothered me.

I think there needs to be options to reposition HUD elements added to games for this kind of thing, m,ake them more transparent, floating, or eye tracking etc. etc. Maybe only appearing when a button is pressed etc.

This is a useful discussion I think and also makes one think that maybe going VR headset is a better option ...

If someone would make a 32" UHD monitor that ticked all the boxes these TVs do at more TV-like price, most of this would be moot. ;)

Yeah, your conclusion is pretty much exactly what I have been wishing for too: a 32" UHD monitor at a TV-like price with a TV-like featureset. It feels downright absurd that you need to pay more than the cost of a 48" CX for the current top PC monitors, which while matching its resolution and refresh rate have worse color gsmuts and accuracy, either low-count FALD or are edge-lit, lack HDMI 2.1, are often locked to G-sync only, etc., etc. Currently the options for those wanting a large (for a monitor) and fully featured high refresh rate monitor are buying a full featured but ridiculously large TV, buying a more expensive monitor with fewer features, or buying a fast monitor that sacrifices resolution on top of even fewer features. So for me, I'm sticking with option #4, waiting for a better option.
