    Do you mean that you use it as computer screen also or just TV?

    This superbly equipped LG I had to because of unpleasant feelings in the eyes go back the dealer. Be careful when using PWM hi. Pet

    Guys, is this the best 40-43" monitor right now? If not, what would you recommend? I know the Phillips one has ghosting issues and the Dell is rather underwhelming. Are there TVs with decent response times?

    I'd appreciate your input.

    Best 43" are the Sony X800D (VA) and X800E (IPS) TVs.

    If response time is paramount this is a bit better than the Sony TVs. The picture quality from the Sonys is better and I believe the Sonys don't use PWM dimming, but I could be wrong on that. I think the Sonys also have some limited 120 HZ at 1080p capability.

    Also, if the PIP, PWP, and KWM features are useful to you, this is much better than the Sonys.

    The other 40+" monitors out there are all worse or similar to this.

    Thank you for the information. I'm sorry I'm a bit of a display noob. I guess PIP = picture in picture, but what is PWP and KWM?

    I don't game a lot, but the LG's GTG response time is 5ms whereas the Sony's is 12.8ms. I've never played on anything over 6-7ms, will it be very noticeable? I'm not super competitive, but I play some Overwatch and StarCraft. Also, the input lag of the Sony is 34ms for 4K 60Hz HDR, isn't that pretty bad? I'm not sure what the LG's is, they're never listed for monitors.

    When you say picture quality is better on the Sony (I assume you mean the IPS version), do you mean in terms of color accuracy? That's somewhat important to me. Also, which has better blacks and less backlight bleed / near-bezel color shift?

    Finally, which has better speakers? I will be using the speakers mostly for watching youtube videos and such, so they need to be decent, but not amazing.

    I'm reluctant to get a TV in lieu of a monitor because I've never done that before, but if the Sony is noticeably better, then I will go with it. Thanks and sorry for the barrage of questions.

    How does this compare with the Acer ET430K?

    34ms Input lag is horrible. For a 60hz panel, you want under 16ms input lag or you get more then 1 frame of lag.

    Regarding response time, it's all bullcrap. Monitor/TV manufacturers should be sued (lol) for all their false advertising in this area. You have to look up independant reviews by professionals who use oscilloscope and other photo sensors to determine the real response time. Ever noticed how every single TN monitor says 1ms? and every IPS/VA says 4-5ms? It's all complete bullcrap, they say 4ms average but in reality it's 12ms, with some pixel transitions taking 20ms and others 8ms. Things like BenQ blp3200 says 4ms but in reality average 16ms with max of 40ms.

    The Sony X800D has a VA panel which means there is going to be way less backlight bleed (on average, I never seen a VA with loads of orange) and no gray IPS glow (eww on TV size), which means it looks better in dark scenes. However the negative of this, VA panels often have slower pixel transitions in dark scenes and if it's too high, can cause smearing (aka looks worse then traditional blur). I prefer VA because IPS has that horrible glow in dark scenes, but VA is also hit and miss if your a gamer due to the response issue.

    Anything over 27" right now is hit or miss for gaming.

    Thanks. I was considering the IPS Sony, as I prefer IPS to VA. But the response time and input lag points you raised have got me thinking I should probably just go with the LG. Kudos to people who make TVs work as monitors, but I feel like there's always some major compromise. This LG is definitely not perfect. But it's better than the Dell. I wish Dell would release a premium monitor in the 40-43" range.

    I just want a 40-43" 4K OLED 120Hz HDR, 100% Adobe RGB, G-Sync monitor, why doesn't that exist. :D

    "I prefer VA because IPS has that horrible glow in dark scenes"

    You know, the color and contrast shift in VA panels is inadmissible drawback and has always been a deal breaker for me. Limited and inaccutate color representation and so on. The positive sides are not enough to justify this. And finally IPS panels are the most expensive technology in LCD screens, even tough they ditched the S-IPS displays - the best LCD displays ever created, and did this out of financial considerations.

    Some people keep saying this but I have a TN in my lounge room from 2008 that has zero glow, zero blb and looks fine even far away. Yet the IPS i'm sitting right infront of right now has a white area in the bottom left and I got lucky, an ultrawide IPS i had before it it looked like someone was shining a yellow torch in the bottom left and a white one in the bottom right. Even the 28" 4k TN I had was excellent, it's not like Im going to be sitting on the damn floor or on a 45 degree angle, the only time it looked a little dark at the top was when I sitting so low it was ridiculous.

    I recently tried a $400 AUD 32" VA monitor and it was amazing quality. No BLB, no glow, could stand anywhere in my room and it looked excellent, only downside was the respones time was horrible it smeared everywhere.

    I also bought an IPS tv once. my god that was bad, the off-axis gray glow was insane it made Alien look like some washed out garbage.

    The only IPS I actually like is the AOC AGON ag271qg and I got mad lucky with that panel, and it cost $900....

    If you have that much to say about VA being bad, you must really hate TN... O_O

    on lg site they claim its gamut is 72% NTSC. 72% ntsc means 100% srgb, isn't it?
    I'm looking for a big monitor for watching movies on streaming and editing my photos/video. 100%
    of srgb is the minimum for me seen that wide gamut big monitor are too expensive for me now

    Fry's has this monitor for $578 /w promo code. It's in the weekly circular. No ship obviously. I think the deal ends the 16th.

    How does this monitor compare to the Dell P4317Q? What are the pros and cons?

    PWP was supposed to be PBP which is picture by picture, which is a screen split. KWM = Keyboard Video Mouse. This is the function of the monitor that allows you to hook up multiple computers to the same monitor and control them using the same mouse and keyboard.

    I didn't notice anything painful in FPS games on the LG. The input lag on the Sony is likely noticeable in FPS games, but its very dependent on the person. 34 isn't so high as to be unplayable for most people.

    By picture quality I mean that the contrast is better on the VA Sony panel and I believe the IPS Sony has a wider color gamut than the LG. The Sonys might also have better subpixels, which would make text clearer. I also presume the Sonys won't have the edge shadows that the LG does.

    The speakers on the Sony are likely better, but I used the ones on the LG and they were perfectly acceptable for watching videos and such.

    most of youtube videos are still 480p. One question for who own this monitor, how do they appear?
    thanks

    I've had my monitor for about a month using it 10+ hours a day. Ask me anything (as long as it's not too much work for me to answer). :)

    I am overall very happy with the monitor. The only issue (which isn't much of an issue) is the issue other people have also mentioned, that the monitor occasionally flash to black for half a second. It hasn't happened more than once per day so far though. The monitor may or may not have PWM but it is nothing that has bothered me so far (maybe I am not as sensitive as other people) My previous monitor was a 2233rz (120hz monitor).

    "The monitor may or may not have PWM"

    Well, it has PWM and there is proof for that. That`s the cheapest dimming method and given the price it`s understandable, but the LG guys write everywhere *FLICKER SAFE* which is a bold lie.

    Agree that LG shouldn't be misleading people but I don't see flicker even at %20 brightness.

    I wouldn't let PWM keep you from buying this display unless you know you have a sensitivity to PWM.

    I don't see the dark bands at a reasonable viewing distance either. I see them if I get close and get the angle right. I couldn't imagine using this display so close. It's too big.

    Given the price, I think this display is an great placeholder until 40" 4k FALD HDR 144hz monitors are a thing.

    Don't you guys find such big monitors hard to use for computer use, say gaming with keyboard etc?

    Oh, sure, I didn't mean to say that they should get away with lying. All I wanted to say is that whether or not it has PWM, it's nothing that has bothered me in my use of the monitor.

    Surprisingly no. I was against such big monitors for a long time, but I decided to pull the trigger for this monitor anyway since I am going to be using it primarily for productivity (instead of getting a multi-monitor setup). At a proper distance the size really doesn't bother me and it also works fine for non-competitive games (I played a fair bit of GTA V).

    You're right. 43 inches is too big. Ignore the fact that every other thread in the display forum is about looking for a good 40+ inch 4K display. :angelic:

    Lol. Yeah, people have been asking "isn't that too big to use as a monitor?" for years now. My first large display was the Westy 37" that was so popular years ago, and it was a game-changer in terms of immersion. Today, with 4K becoming mainstream, the case for a large monitor can be made even easier since 4K is so difficult for most people to use on smaller displays if they don't want to use scaling.

    I think the 43" displays are in the sweet spot for me personally, in terms of size. My Samsung 48" is just a hair on the large side, which is unfortunate because the only thing stopping me from getting an OLED is the fact that I currently can't seem to find one smaller than 55" (aside from the very short-lived Dell 30" OLED monitor). And OLED makes all of these little side discussions where people argue the merits of IPS vs. VA, etc. moot as it supposedly blows ALL traditional LCD tech away in terms of IQ.

    The only problem I have with 40" is the lack of aftermarket stands and mounts. Seems like everything is for smaller PC monitors or much larger TVs.

    There are a few arms suited to the 40" class but I don't like arms. My display is sitting on a plastic step-stool as I continue to search for a stand. Ghetto as hell.

    It's easy, I just assume you and everyone else is just crazy. Dunno if there is a big monitor that size with the boxes ticked. e.g good response time, good input lag, no pwm for starters. I know the Philips everyone loves has horrible smearing.

    Sad to read about the PWM flicker, I thought I had finally found my big 4K monitor. *SIGHS LOUDLY*
