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