Anyone got any experience with 4k/UHD/OLED laptop displays they could share?
Title, really... I've been thinking of breaking free of the limitations of 6-bit dithered laptop displays (is there such a thing as a fully 8-bit one, without going to UHD?) and maybe it's time to go 4k as well. But I've never programmed for high DPI before (Windows, C++, wxWidgets) so I'm not sure what's involved.
Anyone got any experiences they'd care to share? Do many programs break or stay shrunk on Windows these days? Or does Windows do a blurry upscale if a program isn't high-DPI aware? Oh and 120fps/144fps screens too, if there is anything interesting to know about them. |

If it's about user experience: yes, one Win10 UHD system here, not OLED, but 100% Adobe gamut: AU Optronics AU309B (8bit).
Well worth it. Big gain for CAD, stills, video. Chroma and it values have a new meaning now, already on the editing desktop, not only later on the OLED TV X-} A bit harder to use on anything basic. User just has got to be aware and order Windows to scale per program. I am globally using 150%, but have to call exemptions. Some GUIs need to stay at 100% and come out rendered tiny, so a challenge for older eyes. (Vegas for instance, otherwise second monitor will shift and add black bar on one side only.) MWSnap (Screenshots) also need special settings. Well, at my birth 2 watchmakers were present, and one died shortly after... A few other GUIs come out blurry, yes, but this is no showstopper at all. We've learnt to call that antialiasing, haven't we ? I am not dropping Win7/XP FHD/UXGA systems, these are still good to go, (6bit being down the toilet ot course, I have to live with that on the previous 6 systems, ease of handling and readability is still worth it.) From a user side I see no big shift a programmer should have to make, even abandoned software runs beautifully here. (...provided user is willing to jump through many hoops for the first weeks and finally getting Win10/11 chained tightly...) And I am NOT encouraging anyone to go Win10 for that reason only....

Emulgator mentioned 2nd monitor,
I use 1280x1024 4:3 2nd monitor with a 4K HDR10 on W10, I occasionally have problems with DGIndexNV and MeGUI, where window was last used on 4:3 2nd monitor, and when try to run again at later date, does not show [appears on taskbar but no visible window]. With DGINdexNV, can go find its .ini file in same dir as DGIndexNV and change window coords for both windows to 0,0. With MeGUI I usually just disable 2nd monitor, then run MeGUI and it appear, then enable 2nd monitor again. A bit of a pain, but no great hold up. EDIT: I had no idea that some laptops have only 6 bit color. [well not since bout W95/W2K] EDIT: 4K 10bit, and 1280x1024 8bit, work OK together on W10; nvidia card [except for above disappearing windows thingy]. Also, I probably throw a little bit of a spanner in the works by having my 4:3 monitor on left of 4K, instead of right of 4K [they sort of by default assume 2ndary monitor is right of primary monitor. In the display arrange graphic, you can move the 2ndary to left of primary with the mouse].

I think most are, unless otherwise specified. There's a handy utility called Ditherig for controlling the Intel dithering which fools you into thinking the display is better than 6 bit (turn it off and you'll easily see banding). |
