Appiah's comprehensive 15KHz monitors list of caveat emptor - Page 5

idrougge · 16 July 2018, 14:11

I think it makes sense to remove the Samsung 71x series. Evidence that they work with 15 kHz is spotty to say the least.

I did a quick google search for this model and couldn't find it. What country is it sold in?

Completly agree, lately I have tried Syncmaster 710N and it did not supported 15kHz.

I just tested the following monitors - unfortunately none of them worked with an Amiga RGB signal, but I guess that is also a somewhat useful result:

HP P240va
Samsung S24E650
Lenovo LT2452pwC
Lenovo L2250pwD
Lenovo D221
Lenovo T2454pA
Lenovo L192p

Just tried my work monitor (Acer K242HL) and it seems to work:

Anyone know if the Acer G276HL is capable of doing 15khz without a scan doubler? I saw it listed on http://15khz.wikidot.com/ but I think there are various revisons and model of this monitor. The one I'm looking on Ebay say G276HL GBD.

kublai · 13 May 2019, 20:40

I received the Acer G276GL GDB today and it's working with just the VGA adapter. My problem now is the screen is not full as it's got black spaces on both sides of the monitor.
The workbench screen is only about 3/4 of the 27 inch screen in the middle and two black vertical bars taking up the 1/4 of the screen for both sides. I tried multi-synce productive and other monitors in system/storage that i moved to system/dev but it's all the same. I tried playing with teh clock frequency on the monitor but still can't stretch the to make it full.

I would love to see some photos of your Workbench on your Acer. Bars on either side sounds like a plus if it means it is properly displaying 4:3 mode instead of forcing 16:9.

Exactly.

The Asus PB248Q from 2014 does 15kHz via VGA quite nicely. Also works fine with the OSSC. The aspect ratio cannot be locked to 4:3 when the VGA input is selected, but it can be done for HDMI signals.

Hello, I purchased a Samsung SyncMaster 710N and didn't work, is there a way to edit the list or add new information? It just stays at black screen when connecting the Amiga. Of course tested with another monitor and works fine. Also, the 710N works with a PC.

zipper · 10 January 2020, 21:14

No wonder - Samsung SyncMaster 710N specs (official):
•Horizontal Frequency : 30~81kHz
•Vertical Frequency : 56~75Hz

Then it shouldn't be on the list, right?

Someone else said that these specs don't really tell about lower sync freqs...

zipper · 11 January 2020, 11:55

Yes, it's possible but not too common. For instance some BenQs do work from 15 kHz and up - mine starts from 24 kHz and 44 Hz (!).

Hi

I've made a copy of this list some weeks ago and published it at https://www.15khz.net .

The main problem with this is keeping two sources up to date. So:

Is it a good idea to move from google docs to github and work with pull requests? What does the community say?

psoma · 26 January 2020, 07:16

NEC 1970VX and 1970NX sync to 15khz but are essentially useless for the Amiga. They don't support overscan at all and cut off the top and bottom of the screen (you get a widescreen viewport) without the ability to adjust V-SIZE. Don't waste your money on these.

Yes, go for it.

Github is a much better way to deal with it and I do not have much time to actually browse the forum as a working dad anymore, apologies for not being too active

Please give me a link to the git and I will remove the information in the first post and link to your github.

Solo Kazuki · 06 February 2020, 07:34

Someone in other topic mentioned about Lenovo T22i.

GearCross · 06 February 2020, 16:26

I made a thread with my findings on the Dell U2913wm and the Lenovo T2324p. Both work but each with their own quirks...

Here's the post with the results.

Some photos of the workbench displayed on the T2324p.
