100% desktop scaling will kinda be hard to read on such a small display @4K, using higher scaling gives issues with some games. I guess it is cheaper to crap high resolution into a small display than adding better PPI @lower resolution.

I'm sorry but that's probably not the 5ms G2G what you are seeing but the imput lag... I have three HP LP2475W's which is absolutely horrible for gaming. I also have three Dell P2314H and those have an official G2G of also 5ms. While in reality the input lag of the HP monitor is way over 30 and absoultely unplayable for games and the Dell has an amazing input lag of only a few ms. Which is better than for example most 120hz, 144hz and even Eizo's 240Hz monitor. Your HD-TV is NOT made for gaming whatever is being advertised... Please inform yourself better next time you buy a monitor. Both of these monitors are IPS/PVA and not TN. Nowadays IPS monitors can be hell-a-quick, so quick that the Dell monitor has been used by a few pro-gamers i know when they were at my man-cave.:banana:

No I am not talking about input lag, input lag would imply I feel delay between what i just typied or did with my mouse/kb/gamepad which not what I talking about. and as for input lag I feel none on my hdtv or my monitor. I been forcing vsync for so long that I dont have issue with that anymore. I talking about pixel response times (2ms gtg/5ms gtg etc) and that stupid sample and hold effect which directly effect the amount of blurring and detail lost when things move fast. to this date nothing compared to CRT in that reguard. anyone that had half decent CRT back in the day knows what I talking about. people that never had one let alone seen or used one wont have clue to what I talking about cause they dont know any better. So again I not talking about input lag, input lag is result of added features and process to image that slow it down and make it feel like everything is out sync with what you doing which not the same as pixel response time which how long it take pixels to change there state. 2ms is to slow in my eyes so 4ms/5ms and higher for that is much much worse in my eyes.

I have 2ms monitor and I find that to be terrible..

You've fallen victim to marketing. If you had 1 monitor(with all other variables being the same) a 1ms monitor vs a 2ms monitor, you would not be able to tell the difference. Period. Acer Xb270hu is an IPS monitor with a listed 4ms response time that has way less total lag than 99% of monitors out there. Signal processing lag is just as important as pixel response time. The actual total lag for the acer is 3ms~, whereas a 1ms TN display could have a total lag of 10ms. So people look at the TN panel with 1ms and say its automatically better than the 4ms acer, when in actuality that would be incorrect. BTW HDTVs have terrible input lag, you are seeing the input lag not pixel response time.

AGAIN I am not talking about INPUT LAG. Input lag and PIXEL response are not the same thing.... http://www.rtings.com/tv/tests/inputs/input-lag read that part that says Note: Do not confuse the input lag time with the response time. The response time is the time it takes a pixel to shift from one color to another, which is significantly shorter than the input lag time. Response time is related to motion blur. http://www.rtings.com/tv/tests/motion/motion-blur-and-response-time Motion blur is what I talking about which has NOTHING to do with input lag. CRT still king what comes to that. I see clear difference in motion blur on my CRT vs my LCD and the slower the response time the panel has the worse the effect is. and motion blur on ips hdtv with 5ms is much worse then the TN monitor I have with 2 ms granted there is no "industry" standard for response times but there clear difference between TN and IPS. people need to stop confusing the 2 things there not the same. Some people wont notice this other will see this stick out like sore thumb. which like how some people that never use vsync dont see tearing in there game when another watching that person play those game with no vsync will see it. This almost as bad as people saying there games are lagging cause of the gpu is doing 45fps instead of 60 but in very very lose sense i could be argue as being lag...

text rendering ? do you realize how small the text on 100%scale on 4K display ? even it showing pretty crisp text, its just to small even most people that using 1440p on 24"/25" scale it to 125% you will need to scale it to above 150% (more likely 200%) for 4K skip scaling issues in windows - software related if the scaling works properly then it might works just fine if not then it will showing blurring/artifact rather than clear so nothing better compared to default 100% for me personaly, when use scaling on a display it basically defeat the purpose getting 4k

Did you read my post? 4K at 24" you'd need to use 200% scaling to match 1080p size exactly. Text rendering would be ridiculously better when scaling works as intended. Everything would be exactly the same size but the PPI gains are massive. I dunno about you but I hate to read small kanji and kana on 23" 1080p screen. Higher PPI would really help. I want better quality not more space (assuming that the display size stays the same). It's all about scaling. Well, actually there shouldn't be any scaling involved when things are rendered natively larger so that they look right on high PPI screens.

@tsunami231 Okay i bite, you are aware that those are marketed numbers? 2ms G2G means Grey-to-Grey. Have you ever played games in black-and-white? That is what Grey-to-Grey (G2G) means... When a monitor is building up colour it is not the 2ms G2G you need to look at but the actually ms for building up those colours with their pixels. You are right, that's not input lagg, but neither is it the advertised 2ms G2G, that's just marketing...

i read your post, my main language also japanese, and never got issue reading them whatsoever except some few kanji, and like this https://upload.wikimedia.org/wikipedia/ja/b/b6/Taito_s.png its kinda impossible to see the lines but i am not picky with pretty text, as long its crisp enough and not grainy/jaggies and to me thats the whole point, in PC(windows) scaling still need to be improved before small 4K display (below 32") is good option to get i experienced many issue with windows scaling... even with adobe photoshop - maya

Too small for 4k. Honestly, who buys those?

Ideal for 200% scale. I have 27UD68 with 150% scale. Looks great. There are some old win32 apps raster scales, but rest works good.

Font is less pixilated. That makes it pleasant to read.

4k(higher resolution) also mean more graphic overhead (wasted or not) for smartphone the 4k is used for VR lately, that what shine aside that, i believe most people agree that 4k isnt worthed you cant see enough improvement/different compared to 1080p on 5" display along the downside with shorter battery life

If you count pixel shading as "overhead", sure. It's not what I'd count as overhead though. But anyway: I'd love to own a 4k display if I had a GPU to run games with it. Being able to see really fine details in games (cough foliage cough) would be awesome. Currently you can't even see individual leafs on trees in games unless you're really close.

I'm Finnish myself so it does hinder my reading speed a lot when I have to guess which character it is since my error correction is really, really low. I can read and write kana no problem but this is annoying when cleartype messes things up since PPI just isn't high enough: https://abload.de/img/clipboard-20fs2n.png I added "pa" there to highlight the problem. At least on my screen your guess is as good as mine which one is "ba" and which one is "pa". On my screen "ba" looks more like "pa" - I can't quite get the fonts to looks right on my screen in general (I'm actually sidestepping to Samsung PLS panel in very near future which may help). When the font is larger the difference is obvious (and honestly, I prefer grayscale smoothing): https://abload.de/img/clipboard-17lska.png Okay, it's pretty easy to figure out from the context that it's "ba" ("harowin baajon" i.e. Halloween version) but still. On my phone (5" 1080p) this would never be a problem.
