LG 48CX

ok my lg48cx has bit the pixel gods in the butt whats the best replacement s90f or c5
Click to expand...

If you're talking about 48 inch versions, they both use the same LG WOLED panel so just get whichever one you can find cheaper.
 
My CX 55 still going strong as my GT7 sim racing display. I’m utterly blown away at the resilience of this TV.
 
Well first off, there is no 48 inch S95F, it starts at 55 inches. The differences vs the S90F is brighter HDR, 165Hz instead of 144Hz, and matte instead of glossy so yeah nothing that is really is worth $1000 extra over an S90F.
 
I just picked up a C5 to replace my CX 48. I tried the 45950a and couldn't stand the coating and the curve. I honestly can't really tell a difference between it and the cx. My CX started getting to many dead pixels around the edges. My son now has it as his gaming tv for xbox. The C6 should be out in like 2 months if you can wait. But the only thing it does is 165hz and a better Ai cpu. The then Samsung looks good but to get the new panel you need to get the 55 and they are all going to a coated screen. I can't stand the coated screen.
 
Yeah dead pixels I could wait for the c6 I’m going to BB to look I could get away with a 55

That matte screen is amazing. I bought a 77" G5 and returned it before the installers even left. I've had the S95F now for 3 weeks and it's been amazing

My CX48 is also developing dead pixels on the perimeter at a rather alarming rate. Bought it four years ago.

This was the main reason I bought the G5 over the S95F initially. But now that I'm settled in to the S95F and on filmmaker mode, I haven't noticed it. The panel is bright enough that it doesn't seem to make a difference to my eyes.

I don't know if I would personally call the matte screen amazing but it certainly has not been an issue for me. I'm a huge fan of glossy and the matte on the S95F has not been a bother at all.

I also like glossy, but the windows and kitchen lights were a show stopper
 
well, waiting for the c6 is pointless the new features are only going on the 77 and 80 something panels this year I might go 55 it's not that much bigger than the 48 I sit back about 30 inches from the screen

I use this as a rule of thumb, in order to stay at or near to within the central human viewing angle, as well as hitting over 60 PPD at 4k.

screen.optimal.viewing.angle_flat.screens_near-and-far_1.png

4k_human.central.viewing.angle_2.png


. .

Using the calculator linked below to apply that 60 to 50 deg viewing angle to a 55" would mean

55" 4k at 60 deg viewing angle = 42 inch view distance

55" 4k at 50 deg viewing angle = 50 inch view distance.

. .

Any 4k screen of any size when viewing in the human 60 to 50 deg central viewing angle gets 64 PPD to 77 PPD.
There is a little wiggle room, but sitting much nearer and you'd get the larger areas of off axis pixels shown in the 2nd picture, and to a greater degree off axis . .
as well as getting less than 60 PPD once at wider than a 64 deg viewing angle - which imo is a bare minimum for perceived pixel density (pixels per degree). 60PPD for LCDs anyway. In fact, text wise, imo OLED non-standard pixel structure benefits from at least 70 PPD, and also on any screen type for desktop graphics and imagery that typically get no sub-sampling or anti-aliasing.

So personally, if I were to end up with a 55" 4k, I'd have to be be viewing it from 42" (60 deg) , and likely closer to (a farther) 4 feet away for my setup. 70 PPD on a 55" is at 46" view distance. I think I could do it, but it's pushing it for my setup's distance constraints even with the screens mounted separately from my desk (which I have right now still running my 48" + other screens on the sides). For my particular setup, I also might have to drop one of the sides screens if I end up doing that, depending.

Your 30" view distance figure would result in a 77 deg viewing angle (17 to 27 deg outside of 60 to 50 deg, or around 9/60/9 .. 14/50/14 depending on how you look at it) , and you'd only be seeing 50 PPD. For reference, a 1440p 16:9 of any size when viewed at 60 to 50 deg viewing angle gets 41 to 50 PPD. So to your perspective, your pixels sizes would look like 1440 - 15xx , and the sides of the screen would be off axis more (where people with 3 monitors across would usually be turning the side screens inward to face them..

Supposedly with the Alpha 11 Gen 3 chip LG has fixed their near black posterisation issues. So a reason to get a C6 over a C5 if that matters to you.

Would any of this fancy processing even work in game mode? Normally game mode disables all that additional processing in order to get the lowest input lag so if that's the case then it wouldn't be any better than the G5.
 
Yea, wonder if if there's any change with regards to the dithering as well. I guess there is a chance, at least.
 
Awnser me this the LG website says for the 2025 c5 at 48 is capable of 144htz but the bestbuy website says 120 what’s the truth
 
https://www.flatpanelshd.com/news.php?subaction=showfull&id=1772643600

From Flatpanelshd article:

"The most notable improvement, however, appeared to be the impact of the 12/13-bit internal processing mentioned earlier. In the side-by-side demos, LG G6 showed significantly less banding and posterization in dark scenes than LG G5, and also less than Samsung S95F and Sony Bravia 8 II QD-OLED TVs. It looked more or less like a solved problem.

It is difficult to capture in a photo, but you should be able to see the results below. Both LG G5 and G6 had 'Smooth Gradation' turned off to demonstrate that the improvement is inherent to the panel and processing, meaning it should apply universally across content types, including movies/series and gaming. We will examine this more closely once we get a review sample."

1772739678751.png


So they're saying the improvements should also apply to gaming as Smooth Gradation was turned off. Pretty good news. However, they made no mentions of dithering improvements.
 
Yeah the dithering supposedly fixes that, but I've heard that near viewing , even ~ 3 feet away from a 55" has visible dithering lines in the G5 according to some sources, so probably the G6 too. Others say it's not noticeable "beyond 3 feet" or some say "beyond 5 feet", but they usually don't mention the screen sizes, and might be talking about 4:2:0 movie (or dynamic compression streaming service) watching, so the info I've seen seems to be reviewers speaking more generally than any solid measurement method. Good news for living room and home theater, but might not be great for ~ 60 deg viewing angle pc "command center" type setups.

If I had a 55" 16:9 at my pc, I'd be viewing it from around 3.5 feet

55" 4k at 60 deg viewing angle = 42 inch view distance

55" 4k at 50 deg viewing angle = 50 inch view distance.

It seems that for this gen, the specs don't really change all the way down to 42 inch, also. (other than brightness, because smaller heatsink, but that's fair).

So even the smaller models keep the 165hz and same processor etc.

So yeah just want to know about the dithering at this point.

Afaik they don't sell the 42" or 48" models in the usa anymore (LG).

For samsung, they use different panels in the smaller sizes, non QD-OLED. (For FALD LCD screens, they also have lower performance metrics, less zones, etc.)

That's why a few of us keep mentioning making longer viewing distance arrangements for using 55" models, to get the full features and PQ represented in reviews and testing (and marketing).

I have to extrapolate and add a 55" representation with it's width and view distances to the first graphic at some point.

The 42 and 48 sizes are quite popular in Europe, but they were a bigger downgrade in previous gens than they seem to be for this gen (for example no 165hz in the 5th gen below 55"). So if the dithering flaw is gone, I could replace my CX with this LG C6 48". Otherwise it's Samsung and 55, doable but a pain to squeeze inside my setup.

I've been focused on G5 threads on avsforum, etc, - and lately the G6 inquiry thread here on H so I was crossing wires. That's because my focus is on tandem stack to compete with QD-OLED screens.

Quick search, will have to confirm:
. .

"the 48-inch Tandem OLED panel technology is not available in the US for the C6 series
, which is limited to W-OLED for smaller sizes (42"–65"). While Tandem OLED (Primary RGB) is available on the 77" and 83" LG C6 models, the 48" C6, C5, and B5 models in the US utilize traditional W-OLED panels"
. . .

"
Key Tandem OLED Models (USA):

. . .
"based on 2026,

LG C6 series 77-inch and 83-inch models will feature Primary RGB Tandem OLED technology, sometimes referred to as the 4-stack panel. These specific large-screen models (branded as C6H) will get the upgraded, higher-brightness panel, while smaller C6 models will likely retain standard WOLED.
Key Details Regarding Tandem Stack in LG C-Series:
  • Models: The 77-inch and 83-inch LG C6H TVs.
  • Technology: These models will use a 4-stack tandem RGB panel, promising significantly higher brightness similar to previous-generation G-series models.
  • Upgrades: These models, in addition to the Tandem panel, will benefit from the new Alpha 11 Gen 3 processor and support 165Hz VRR.
  • Availability: Announced at CES 2026, this represents a major "trickle-down" of top-tier panel tech to the more accessible C-series.
  • Non-Tandem Sizes: Smaller 2026 C-series models will likely retain standard OLED panels without the Tandem 4-stack technology.
This upgrade positions the 77" and 83" C6H as a hybrid between the traditional mid-range C-series and the top-tier G-series (which uses the even more advanced Tandem 2.0"

. .

"While the 55-inch G5 uses this technology, note that the 97-inch G5 model does not use the Tandem OLED panel. The 55-inch G5 is considered a top-tier model for 2025 in terms of brightness and performance."

. . .

The s90f's smaller sized screens were both WOLED instead of QD OLED.

"
For the 2025 Samsung lineup,
the S95F (flagship) features QD-OLED in 55", 65", and 77" sizes, while the S90F (mid-range) features QD-OLED in 55", 65", and 77" models, though some regions or specific model codes may vary, particularly with 83" models using WOLED. The 83-inch S95F uses WOLED, not QD-OLED "


. .

The 2026 samsung gaming tvs will likely follow the same pattern as the S90F chart above:


"
2026 Samsung QD-OLED TV Lineup (Expected)
  • S99H (Flagship): 55", 65", 77", 83" (Note: 83" is generally WOLED, others are QD-OLED).
  • S95H (High-End): 55", 65", 77", 83" (Note: 83" is generally WOLED, others are QD-OLED).
  • S90H (Mid-Range): Uses a mix of QD-OLED and WOLED panels, with 55" to 77" likely using QD-OLED.

It's not that LG doesn't sell 42" and 48" G series in the USA anymore, they actually NEVER sold 42" and 48" G series in the USA to begin with. In fact, there isn't even such thing as 42" G series, which is a damn shame because LG would make a ton of money if they did make a 42" G series with all the bells and whistles as the larger models, of course with the exception of reduced brightness figures given the smaller size.

Scale wise LG probably don't sell anywhere near the amount of 48" and 42" WOLED panels so are unfortunately dragging their feet on allocating tandem RGB production time to it. It's probably why Samsung CBF releasing QDOLED 42" and 48" panels and just use LG panels for that size.

I'm hoping once they have chipsets in them that can do HDMI 2.2 4k 240hz that they'll also let us have 42" and 48" tandem RGB. I've tried 55" and it's just a touch too big for my current setup. If I had a deeper desk I could do it, but it's already pretty deep to allow 3x42" displays.
 
If you were buying a tv for gaming right now for a desk setup what would you buy?

If money and screen size isn't an issue then 55" S95F. LG G6 is a strong contender but it's not out so you can't buy what doesn't exist yet, if you want a better value proposition then 55" S90F instead. If you're not going to get a 55" then just get the cheapest 42/48" LG C5 or Samsung S90F that you can find, they all use the same WOLED panel, there are no QD OLED's in that size.

Well unless you plan on grabbing an RTX 6090 to drive 240fps then you wouldn't find much value in 240Hz. Also, the jump from 165Hz to 240Hz is really not that big, I have both and I honestly don't miss 240Hz at all. 240Hz to 480Hz is far more noticeable.
