Having one on its bum meant that you couldn't actually sit the laptop on your lap without blocking a crucial vent. You also have connectors sticking out in stupid places.

So, I can't find anything that that looks like has perforations. Keeping the lid closed does have one advantage of collecting less dust on the keyboard, from what i can tell.

That is going to depend on the laptop design.

I do not want to lose the laptop in this isolationist environment. I have a different question, and that is, that the laptop has a HiDPI screen so needed tweaks to .Xresources to get it to display in a readable way. However, this is not needed for the attached monitor so is it possible to set things up so that the laptop screen scales things differently from the monitor? I have the following in my .Xresources for the laptop screen. ! ! Custom DPI ! ! Xft.dpi: 192 Xft.autohint: 0 Xft.lcdfilter: lcddefault Xft.hintstyle: hintslight Xft.hinting: true Xft.antialias: 1 Xft.rgba: rgb Xcursor.size: 32 - Which looks fine on my laptop but things look fuzzier on the monitor. How do I get this to be higher resolution for the monitor and it to also work on the HiDPI screen? I use openbox as my WM (and do not use a DE).

Sorry, this line was for the laptop screen. But i have realized the issue. A USB-C to HDMI 2.0 is needed, apparently the type-C multihub sold by Dell does not work for UHD.

Re: F31 - getting UHD external monitor to display at 3840x2160 resolution
I would check the rating on your HDMI cable, the older ones aren't supposed to be able to support greater than 1080p rates, so if you cable is very old it may not support the speed. There is probably something written on the cable ends and/or the side of the cable itself. Mine says high speed on the side which indicates it can support at best 4k-30 and is an hdmi 1.4 cable (assuming the ends themselves are also compliant) but nothing more. see: https://en.wikipedia.org/wiki/HDMI On Tue, Apr 21, 2020 at 1:51 PM stan via users wrote: > > On Tue, 21 Apr 2020 12:40:30 -0500 > Ranjan Maitra wrote: > > > On Tue, 21 Apr 2020 12:17:24 -0500 Ranjan Maitra > > wrote: > > > > > Hi, > > > > > > I recently got myself a UHD monitor. > > > > > > https://www.amazon.com/dp/B07JXCR263?tag=aboutcom02lifewire-20&linkCode=ogi&th=1&psc=1&ascsubtag=4138562%7Cneef17e57867342f0bc4b3af20a9ba60801 > > > > > > However, when I connect to my 3840x2160 resolution laptop and use > > > xrandr (through HDMI, supplied with the monitor) I do not even get > > > an option for 3840x2160.

F31 - getting UHD external monitor to display at 3840x2160 resolution
Hi, I recently got myself a UHD monitor. https://www.amazon.com/dp/B07JXCR263?tag=aboutcom02lifewire-20&linkCode=ogi&th=1&psc=1&ascsubtag=4138562%7Cneef17e57867342f0bc4b3af20a9ba60801 However, when I connect to my 3840x2160 resolution laptop and use xrandr (through HDMI, supplied with the monitor) I do not even get an option for 3840x2160. Here is what I get: $ xrandr Screen 0: minimum 320 x 200, current 3840 x 2160, maximum 16384 x 16384 eDP-1 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 294mm x 165mm 3840x2160 60.00*+ 59.9859.9748.00 3200x1800 59.9659.94 2880x1620 59.9659.97 2560x1600 59.9959.97 2560x1440 59.9959.9959.9659.95 2048x1536 60.00 1920x1440 60.00 1856x1392 60.01 1792x1344 60.01 2048x1152 59.9959.9859.9059.91 1920x1200 59.8859.95 1920x1080 60.0159.9759.9659.93 1600x1200 60.00 1680x1050 59.9559.88 1400x1050 59.98 1600x900 59.9959.9459.9559.82 1280x1024 60.02 1400x900 59.9659.88 1280x960 60.00 1440x810 60.0059.97 1368x768 59.8859.85 1280x800 59.9959.9759.8159.91 1280x720 60.0059.9959.8659.74 1024x768 60.0460.00 960x720 60.00 928x696 60.05 896x672 60.01 1024x576 59.9559.9659.9059.82 960x600 59.9360.00 960x540 59.9659.9959.6359.82 800x600 60.0060.3256.25 840x525 60.0159.88 864x486 59.9259.57 700x525 59.98 800x450 59.9559.82 640x512 60.02 700x450 59.9659.88 640x480 60.0059.94 720x405 59.5158.99 684x384 59.8859.85 640x400 59.8859.98 640x360 59.8659.8359.8459.32 512x384 60.00 512x288 60.0059.92 480x270 59.6359.82 400x300 60.3256.34 432x243 59.9259.57 320x240 60.05 360x202 59.5159.13 320x180 59.8459.32 DP-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 597mm x 336mm 1920x1080 60.00* 50.0059.94 1680x1050 59.88 1280x1024 75.0260.02 1440x900 59.90 1280x960 60.00 1280x720 60.0050.0059.94 1024x768 75.0370.0760.00 832x624 74.55 800x600 72.1975.0060.3256.25 720x576 50.00 720x480 60.0059.94 640x480 75.0072.8166.6760.0059.94 720x400 70.08 Why is this so, and what do I do to get the UHD resolution?

There are bugs that high resolution monitors trigger. https://bugzilla.redhat.com/show_bug.cgi?id=896170 Most current AMD/Radeon are limited to 8k x 8k. The horizontal limit will probably be the first one you hit. You can do two landscape 3840x2160 or three landscape 2560x1600 monitors. You can run the Sharp monitor from a displayport and AMD/Radeon displayports are easy to find. You can even get a fan-less quad displayport card (ATI Firepro 2460). -wolfgang -- g+: https://plus.google.com/114566345864337108516/about -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

$ xdpyinfo | grep dimensions dimensions:6880x1600 pixels (1818x423 millimeters) That's four monitors on an ATI Radeon HD 6870 card, with proprietary drivers.

I agree wholeheartedly with this sentiment, but I'm willing to (someday) give very large, very high definition 16x9 displays a chance. My thinking is that a single 16x9 display of this sort can potentially replace 2 side-by-side displays.

I find that it can be useful having multiple windows open side by side for work. I have become more productive with a 16:9 display compared to my 4:3 display.

Re: 3840x2160 resolution?
Interesting and impressive. A 32" LCD on the desktop does seem a bit much in size and scope. It is configured to be a usable 16:9 aspect ratio. Very pleased to see that. This has been an excellent site I refer to when monitor shopping: http://en.wikipedia.org/wiki/Graphics_display_resolution They tend to have a clue about practical sizes and their impacts. So the one you are referring to is listed as a QFHD... very high quality resolution. P.S.

Not precisely those resolutions, but not far off: mrburns:~% xdpyinfo | fgrep dimensions dimensions:3520x1200 pixels (931x317 millimeters) dimensions:3584x1440 pixels (948x381 millimeters) mrburns:~% lspci | fgrep VGA 01:00.0 VGA compatible controller: nVidia Corporation GT200b [GeForce GTX 285] (rev a1) 02:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 210] (rev a2) That's using the nouveau drivers. I can say that I'd avoid nvidia cards if at all possible. They've caused me no end of trouble on this machine, and I've had much better success with ATI cards.

3840x2160 resolution?
I am fascinated by the idea of having a Sharp PN-K321 monitor (but it will remain a fantasy till the price gets much lower :-). Out of curiosity though, I'm wondering if anyone out there in fedora-land has run a display at 3840x2160 and if so what video card and/or cards you used (and if open source drivers worked)? The manual for the sharp makes it seem a bit weird. You apparently have to run it as though it is two separate 1920x2160 displays - they just happen to exist right next to each other with no bezel separating them. Looking on newegg.com I find a few cards that claim to support 3840x2160, but it isn't clear if they can act like a dual display. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
