At these frequencies, gold plating is used to prevent oxidation. Most oxides are good insulators and therefore cause signal degradation. You'll not notice any difference right away though - it takes time for oxidation to affect the connection and it depends on environment (heat, moisture and...

I detect MONSTER cable fan... It stands to reason that LG would not include an HDMI cable that was out of specs as it's in their interest you keep the monitor past 30 day return window. In addition this LG monitor can detect out of specs cables and will display a notice if it senses an issue.

Yes, considering that Samsung 43" is IPS - LG would be a better unit as long as you can stand (480HZ) flicker and ok with loosing 10pixels around border.

When you lower brightness you lower PWM duty cycle so screen will flicker more. Dell recommends brightness 70 and above, IIRC. 60Hz could be the artifact from turning LEDs sequentially, see the slow mo here. When I had the monitor I found both - flicker and brightness tired my eyes...

I've seen the Acer at the Microcenter - it was $400 at that time. One thing that I noticed right away was backlight that was not uniform (though LG is not either - it's much more pronounced on the Acer). Also do not forget that some reviewers report screen retention on the Acer and Phillips...

Just a perspective on the pricing, it was $400 at Fry's , $550 at Costco and Newegg and I got one for $520 (and still returned due to issues you list, plus flicker). I don't think it's worth spending more on this monitor. Overall, just the only feature that it's got over "TVs as monitors' is...

Samsung TV does not not use PWM between 13-20 (20 is 100%) brightness levels, at lower brightness, levels 1-12, it uses 120Hz PWM. I use mine at 13 which is probably equivalent to 35 on the LG.

I think VX4380 may have the same panel as Phillips or Acer, while Dell and LG have a different, better, panel. Personally, I got a Samsung TV, UN40MU6300, instead of the LG and it's good enough that I will keep it for couple of years. It was half the price of 43" monitors, has much better...

On Samsung UN40MU6300 I do see the lines as well and it appears they are due to sharpening filter. I can remove line shadows completely by turning sharpness down to 25. At 35 they are very faint and very visible above 50.

That is very true. Flicker bothers me and above backlight 12- there's no flicker. I'm using it with Fusion 360. Due to color scheme (gray on white) normally I do not notice 'trails'. If I make my model black, than yes, for a split of a second, when rotated fast you can see a yellow 'shadow'...

I have MU6300 and I see smearing only when moving window around quite fast but not when scrolling text (maybe because letters are small since I'm using 100% scaling). DSR on LG 43" monitor was driving me crazy (and flicker) and I'm happy to trade DSR for little bit of smearing. Note that...

Good viewing angles, uniformity, high contrast, supports 4:4:4 chroma, 60Hz on all ports and remote. Great as monitor especially if you can get it for less than $300.

I agree about the contrast. After returning it I got 40" Samsung (UN40MU6300) - uniformity (no DSR on Samsung) and especially contrast are much better (and no flicker above 12 brightness!). With LG 43" I had difficulty reading text (I use 100% scaling) at edges of the screen especially when...

Flicker depends on brightness level. Dell claims using their 43" >70 should cause no noticeable flicker. For LG I found >75 to be comfortable but too bright. At levels below 50 flicker 'stings' your eyes and may cause headaches (not everyone is affected equally). I don't overclock these days...

I returned mine, even if one was available for free I would not be able to use it - mainly due to flicker (had bad experience with LG tech support as well) 43" Dell: good quality but flickers and expensive 43" LG: flickers, some report brief screen blacking out, uniformity issues 43" Acer...

Which model did you get? I need PBP so a TV is not an option for me unless paired with a HDMI multi-view box, but than it gets expensive and I don't know if signal quality suffers.

You can expect same issue with flicker if you are using at less than 75 brightness. Even at 480Hz (upgraded from 120Hz) flicker gave me a headache. I think gets worse when using PBP - as I did - because while I focused on one side the other side was beaming (flickering) light from a corner...

You cannot avoid it completely but you can lower color temperature (and/or gamma shift) for tasks that do not require specific white point. Generally speaking, OLED by it's nature emits less 430nm (blue) light than LED except for quantum dot backlights (Samsung QLED, Sony Triluminos) that...

The larger the color gamut the less (lower intensity) blue light panel will emit (you can decrease color temperature maintaining decent color gamut). I read that LG AH-IPS technology is using multicolor LED backlight which increases output of red and green spectrum. QLED panels do the same...

In the video, blue light blocking glasses are reviewed in another video - they basically block blue light by reflecting it. If B component is not set to 0 your monitor is sending energy in blue spectrum to your eyes. Earlier monitors (or ones with sRGB color gamut) send more energy in blue...

This is widely reported but I have dismissed at first since LG upped the PWM to 480Hz. Original 120Hz was unbearable from the start, 480Hz is masking it pretty well and if you can use the monitor with brightness >75 or so than it, probably, is not an issue. This is a great monitor, btw in...

Interestingly P4317Q GTG is 8ms which is the same as 43MU79. We were wondering if UD and MU have different panels - how do you know that the one in Dell monitor is different? I looked at Dell's reviews and found this one which seems to match my experience (only that bottom discoloration on my...

It has vibrant colors and ok horizontal viewing angle. Vertical viewing angle is not so great (top and bottom are dimmer when you sit 2ft away which is compounding issue below ). Screen is quite bright and I use it in 'dark room 1' picture setting to make it darker. There's no screen...

I found this site that gives screen measurements for different screen ratios and given, single, dimension: http://screen-size.info/ Maybe someone will find it interesting... For example, I used to have 1080p laptop with 17.3" screen. I think that was the highest dpi that I would go for...

I have three computers (two laptops and one desktop) connected and have never experienced a 'shut down'. However, I only got one message that I should use supplied cable and only when I powered the monitor on and off multiple times (did not know if it was on or off). I use three HDMI cables...

Electronics could be the same since firmware for UD updates also MU. MU has 3yr warranty on panel, 1 on controller, UD 1 year warranty. Also MU is specced at 8ms GTG and UD 5ms. That's about it. My MU has slight DSE and pink hue on the bottom -so far no one else have reported any issues with...

Do you get pinkish hue along with decreased brightness at any of the corners? For example, look at a photo of a snow, is bottom near the bezel not white, but pink/rosy?

I have not seen the Phillips but I can tell you that LG seems too bright for me. I'm using it at 30 (night) to 60% (day) brightness.

I am really torn about this monitor. Side by side picture is great (and does not require any software). However small issues are adding up: unable to change picture settings in PBP mode (have to go back to single picture, make the change and go back to BPB), dirty screen effect, pinkish hue...

Based on ratings.com review Sony 720E has low black uniformity and 8bit panel- which pretty much removed it from my list.

Yes there is some darkening at the sides due to viewing angles which makes shadows more pronounced. If you look at the photo shadows are uneven therefore they cannot be solely attributed to viewing angle. Shadow also varies with brightness (it's harder to notice at 100% brightness) therefore I...

I bought this LG because of side by side picture feature. I always miss vertical space and there are no monitors that offer 1920x2160. I feel that 43" 4k is perfect if you look at it from 3ft as it leaves more work space in front of the monitor.

Here's a photo my 43MU79. Uniformity is better than my TV but shadows do bother me a little especially when in side-by side split picture mode. Does your (UD or MU) look better?

From what I understand there are no IPS screens per se as it's a generic term indicating particular technology. I'm guessing it's the same type of panel as in UD but driven (slightly) less aggressively because of 3 year warranty.

I just got my 43MU79 and find it not uniformly lit. Left and right sides are darker with bottom corners more than top. How uniform should I expect the screen to be? I can mitigate it somewhat by making picture warmer (so white is more yellow) with dark room 1 setting.
