Samsung 4K 1ms monitor $754 it has begun - Page 55

In the real world that 1ms response time is meaningless anyway on a 60Hz monitor.

I read somewhere that the actual LCD panels themselves have a physical limitation on their true pixel response time, being somewhere around 10-25ms, for black-white-black and that the only real major thing to look out for is the input lag for the circuitry behind the panel and that is the reason why "1ms" advertisements are BS. Not even including the obvious "grey-to-grey" cheating.

What do you know about that?



With my ASUS VS238H, I either get noticeable ghosting or what I believe is called coronas. See: http://www.blurbusters.com/faq/lcd-overdrive-artifacts/

When I first heard about LED TVs I was quite interested, thinking they actually used LEDs for the pixels but it turned out to just be a back-lighting method. Wasn't too silly to think that way, considering Plasma screens are about as different as what a true LED monitor would be.

I've pretty much lost all hope in LCD tech and am not looking forward to any advancements since they all seem like hacks or cheats with little to no effect, or with serious side effects.
Instead, I am looking forward to when we finally get a new tech. Like OLED.

http://en.wikipedia.org/wiki/Comparison_of_CRT,_LCD,_Plasma,_and_OLED


Weighing the pros and cons from that comparison it makes me wish I kept one of my CRT screens. I'd love to give Terraria a test on one to see how it would look in terms of ghosting compared to either my my LCD screens. Free falling to Hell takes a while, and shows some bad ghosting on the way down. Like, noticeably bad. See below.

But @120hz you have only ~8.34ms per frame. I don't think vg248qe has anywhere near as long as that for black/white transition - there's no way that it lags 2-4 frames behind, as you can see each individual frame with strobing quite clearly

What do you know about that?

That could be with reference to usual performance for the panel in their native ('unaccelerated') state or variation depending on the transition being performed. With modern panels it is not at all misleading to say that some pixel responses occur in '1ms' or '2ms' with strong grey to grey acceleration. But there is always a degree of discrepancy between the fastest and slowest pixel transitions, depending on the shades involved in the transition. On a VA panel this discrepancy is greatest, in that some transitions could occur at say 4ms (which means that any motion blur you see is a function of eye movement at 60Hz or indeed 120Hz and not the pixel response itself) whereas others could take 20-40ms even.

On a fast TN panel like this one you can expect using its 'Fastest' setting that some pixel transitions occur at 1-2ms whereas some may be closer to 10ms. Using modest acceleration ('Faster') you can expect some transitions to occur at maybe 2-4ms and some again at around 10ms perhaps higher. As users point out above the 'Faster' setting is visually much more pleasing because it is free from troublesome artifacts (inverse ghosting/overshoot) caused by excessive acceleration even if the pixel responses are technically slower. And as pointed out in the article I linked to in my previous post (which I highly recommend everybody reads - http://pcmonitors.info/articles/factors-affecting-pc-monitor-responsiveness) the pixel responses don't need to be pushed to 1ms or even anything lower than 8ms on a 60Hz monitor to reduce trailing; retinal blur linked to refresh rate is the important limitation there.

Input lag is a separate issue and at any rate is not really a problem on this monitor from what users report; if a user does find it a problem on this monitor then it's probable that 60Hz monitors are going to be too much of a barrier for their enjoyment regardless of input lag.

Just looked at Overclockers UK and they don't have this in till the end of May. mad.gif

Try ebay. Probably cheaper as well. I've seen this monitor $200 more expense for U.S. sites when compared to ebay.

just a heads up, preorder from amazon is available again for US and they dropped the price to $599 instead of $699

Hrm, a TN panel? No thanks. I'll wait until IPS 4k panels are at a... reasonable price range I think.
