**** BEGIN LOGGING AT Fri Jan 14 02:59:56 2022 **** BEGIN LOGGING AT Fri Jan 14 04:40:03 2022 Jan 14 10:30:05 Does anyone have experience with usb display connections? Jan 14 10:32:00 I have Thinkpad T520 and I'm trying to connect it to HP Compaq Jan 14 10:32:18 L2311c monitor with usb Jan 14 10:32:51 But monitor is not detected Jan 14 10:33:08 I know that there are various ways of doing it, and I know that some of them require special hardware. Jan 14 10:33:53 afaik the "DisplayLink" method is the most popular one that doesn't require special hardware support, as that works using regular USB communication. Jan 14 10:34:38 Yes, I have diaplay link installed Jan 14 10:34:47 Display* Jan 14 10:35:28 It will only actually work if whatever's on the other end of the USB cable actually says "DisplayLink" on it. Jan 14 10:35:53 At the moment I'm slowly coming to conclusion that T520 is just not able to connect via usb Jan 14 10:35:56 If it doesn't say "DisplayLink", it probably uses one of the technologies that requires special hardware on the host side. Jan 14 10:36:33 Ok, so it might be that it requires HP laptop Jan 14 10:38:11 You might want to try it in various USB ports if possible, since I think where the special hardware is used, it tends to be only on a select set of USB ports. Jan 14 10:38:41 but I suspect there's a good chance that it will be incompatible. Not sure if Lenovo and HP use the same standards. Jan 14 10:39:50 Good idea! I tried two ports at the side of the laptop, but forgot that there is also usb port at the back, gonna try that next Jan 14 10:40:21 And thought of looking through bios settings as well Jan 14 10:42:23 Looks like the T520 was from 2011, so highly doubt it will work. Jan 14 10:43:37 Yeah.. Jan 14 10:45:46 I guess I'll just buy another monitor with DVI connection, if I can't get this to work Jan 14 10:46:40 I can connect to monitor via VGA, but image quality is blurry and my eyes don't like it. Jan 14 10:49:13 You mean DisplayPort? Jan 14 10:49:25 Looks like it has VGA and DisplayPort. Jan 14 10:49:40 vajb: thinkpads usually have dvi in docks Jan 14 10:49:41 No, I mean VGA Jan 14 10:49:48 WRT VGA, maybe try swapping the cable, or maybe even turning the cable around. Jan 14 10:49:50 and sometimes hdmi Jan 14 10:50:13 as for vga, yeah, i second getting GOOD cable Jan 14 10:50:20 No, I mean as opposed to DVI. You said you might get a monitor with a DVI connection, but looking at specs, T520 doesn't have any DVI output. Jan 14 10:50:26 KotCzarny, problem is that monitor does not have DVI Jan 14 10:50:28 only DP and VGA outputs. Jan 14 10:50:49 Ah, I have a dock, forgot to mention that Jan 14 10:51:01 Ah right. Jan 14 10:51:28 dvi is essentially the same as hdmi Jan 14 10:51:35 for connecting purposes Jan 14 10:51:41 I've tried two cables but result is always the same Jan 14 10:51:43 what inputs you have in monitor? Jan 14 10:51:52 I'm still using VGA for one of my monitors. I have to have the cable in a certain way around, otherwise the image is fuzzy. Jan 14 10:51:58 Also my tv has that with VGA connection Jan 14 10:51:59 I tried buying a new VGA cable, but that was worse. Jan 14 10:52:27 Monitor has only VGA and USB Jan 14 10:52:48 so, only vga-in Jan 14 10:53:28 get some second hand nec with plethora of inputs and ips panel? Jan 14 10:56:45 I think I'll just get another display which has DVI as it was working with it Jan 14 10:57:26 Actual reason to this hassle is that my other monitor died and I didn't look carefull enough when I bought replacement... Jan 14 10:57:54 for blurriness try different display modes too Jan 14 10:58:02 maybe it's using wrong resolution Jan 14 10:58:13 dropping from 75hz to 60hz could also help Jan 14 10:58:38 For blurrines I've tried everything that I could think of Jan 14 10:58:49 Supports only 60hz Jan 14 10:59:08 Only thing that works is to drop resolution to 1280 x 768 Jan 14 10:59:21 But that is unacceptable Jan 14 10:59:28 what is native monitor resolution? Jan 14 10:59:56 or give us the exact model Jan 14 11:06:06 HP Compaq L2311c, it has 1920x1080 native resolution Jan 14 11:06:55 TN, you should grab something better.. Jan 14 11:08:36 Yeah, gonna buy something cheap and used as always ;) Jan 14 11:08:52 look for nec ea234wmi Jan 14 11:08:56 it's quite nice Jan 14 11:10:33 Thanks for the hint. Jan 14 11:10:54 Hmm .. 22 W, not the best efficiency. Jan 14 11:11:32 Maybe it doesn't matter. Jan 14 11:12:28 it's a professional monitor, so quite configurable Jan 14 11:13:00 My main monitor is described as a "professional" one too, though I'm not sure what that means. Jan 14 11:13:18 usually it's either quality, or configurability Jan 14 11:13:29 Acer V226HQL, 22" rather than 23", otherwise same specs afaics. Jan 14 11:13:40 (and I've measured it as consuming about 10 W) Jan 14 11:14:10 it might be dynamic contrast enabled Jan 14 11:14:20 ie. lowers power, bumps the brightness Jan 14 11:15:07 Actually, this one is rated at 19.7 W on their specs, so maybe I just have it dimmer than they expect. **** ENDING LOGGING AT Sat Jan 15 02:59:56 2022
