It's not the size that matters when it comes to monitors, it's the resolution. But if you're near sighted and you need big characters on the screen then it matters. For example, a 32" screen has the same amount of pixels as 24" at 1080P. The images and text will be bigger but not more image or text. A picture is worth a thousand words. Checkout the image.
My eye sight is still fair good, I see the characters fine with no flicker at 30hz. My primary use is for trading and secondary youtub video. My 17.3" 1080P laptop characters are smaller vs Seiki 39" cheapo 4k TV. To bad it's discontinued, i'd like to buy another so i have a matching pair for 8x 1080P monitors.
It's Mr Gekko. His monitors were 20" LCD, LED was available but really expensive. Like his Herman Miller chair and Brioni suit ...
No reason. I have two 42 inch 4k TV's that I use for monitors. They are just amazing. TV's like these can be had for $250 to $350. My second one even had a monitor setting in the setup menus so I didn't have to go through the settings to get everything correct for monitor use. Now when the 50 inch curved screen monitors get down to that price...
Flicker? Why are we talking about flicker? The world should be done with that by now! We no longer have CRTs, and older LCDs have only that incidental flick thing if you chew crunchy things that makes your skull move vertically while watching the screen. Yes? Flicker? OMG please tell me people are no longer banging on about refresh rates in the hundreds. 30Hz will do it for ya', folks. No need for more than that when trading.
it comes from running 4k video full screen at 30hz, refresh rate isn't fast enough, not the exactly the same as analog tv
This is not true in my experience. There is no flicker on a 4k monitor at 30 hz like there is on an old tube. 60 hz is the new norm for inexpensive TV's. A cheap graphics card will run a 4k monitor at 60 hz. A new i7 will run a 4k monitor at 30 hz with no additional graphics card. I run both my monitors at 30 hz. One because of an old graphics card, the other with a newish i7. I would never even think of using anything else again. Both of my monitors are Seiki but if I were buying one today I would look at Spector and Hisense from Walmart. Remember, if your monitor does not have a monitor mode in the setup, you will need to go through the menus and adjust the setup to get rid of the horrible lag when running in TV mode.
