New monitor that works with PAL resolutions
Thought i should mention this, i'm not sure if this works for everyone but according to Laz on Safir his BenQ G2420 works fine on 15khz resolutions with his A1200.
to the thread in Swedish According to the specs it seems like it should not work though? Last edited by fryguy; 28 October 2009 at 20:32. Reason: Added pics to thread. |

Was thinking of buying an RGB to VGA connector so I could get a true 640x480 60Hz Workbench on my VGA screen, but of course the 15kHz modes wouldn't work then. This flat screen might be the solution!
I was told that Benq have listed this screen as not being able to go lower than 20kHz or something. If this is the case then could it be that other production runs of this screen might not accept the 15kHz signals? |

The Sampo LME-17S3 handles Amiga 15khz as standart, but it does not come cheap!
Also does the Sony PVM-20M2MDU. As a rule of thumb, if a Sony PVM monitor has an analog RGB input, it will be a suitable monitor for old-school RGB gaming (ie. 15.75kHz). Spanish industrial monitors suchs as Lazkun LZKPE19OF00. Mitsubishi Diamond Scan 20M (model HC3925KTK), is a CRT max resolution 800x600 Sceptre C-NagaV 19" works in 15 khz The one at this link http://www.converters.tv/products/vga_to_vga/474.html Last edited by gulliver; 28 October 2009 at 21:25. |

Doing a little basic research, the official BenQ website tells us that the G2420HD only supports 20khz. If the information in the original post is true, then it's some kind of a "hidden" feature only few people would discover. Could doing this harm the monitor?
I have a BenQ G2220HDA, which I recently aquired. I will try tomorrow, maybe... |

Hi FryGuy,

I have one of the G2420HD's, but never thought of trying it with the Amiga. The BenQ monitors are cheap as chips here in Oz: http://ijk.com.au/branch/ijk/product...ucts_id=122408 Will plug it in tomorrow and give it a go! Cheers, Red |

It looks like the VGA cable is directly connected to the Amiga. What type of 23pin to 15pin adapter are you using? Is it the silver supplied with A4000 jobby?

@DDNI: it's not my pictures, but the person who tried it used a standard C= VGA adapter AFAIK.

Hi All,
Plugged my A500 into the BenQ G2420HD this afternoon. It does indeed scan down to 15Khz!! Just used a quick 23pin->15pin VGA adapter hack as shown. Will plug the 1200 in later on to try some of the other screen modes, PAL/NTSC etc. Will report back here. Cheers, Red |

Yep another swedish Amiga user also bought a 2420HD and confirmed that it works for him too.
I tried looking for my VGA-adaptor yesterday to try with my G2400W but i suppose it won't work as the specs says it only syncs down to 31KHz. Couldn't find my VGAadapter though :/ |

A quick translation of the Swedish thread: (the Benq LCD)
+ scrolls smoothly in Pinball Dreams smoothly (no 50-to-60Hz resampling) + overall, a good screen for gaming - interlaced modes aren't deinterlaced (Not surprising. I wonder if it's perfect (as perfect as on A3000) with a Flickerfixer without Scandoubler? Should be.) - hires modes result in filtered fonts, no way to select a "good" resolution They mention 1280x1024 to get crisp fonts in 640x512, but it's a 1920x1080 screen, so I'm confused. And Gulliver that's some ACE lists you have there - a bigger problem is finding sellers in Europe. Do you have some voodoo magic lists of them, too? I'm looking for a NEW 19-20" 15KHz, 50Hz RGB-CRT. Arcade monitors like Hantarex are perfect but they lack enclosures. |

Looking at the screenshots, 4:3 is stretched to fit the monitor. Blech. Also, the o's in the font in the WB shot are not equal.

Hi All,
Tested all the screenmodes. Seems OK with everything except DBLPal and DBLNtsc modes (~29kHz) Oddly enough, it complains about them being out of range. 50HzPAL/ 60HzNTSC both worked fine in lores/hires. Text is certainly clear enough to play games. EURO72 modes appear the clearest when upscaled to fit the screen size. Certainly clear enough to do word processing or coding. Cheers, Red |

Just ordered one of the BenQ G2420HD.
Let you know when it arrives if the newer ones still support 15 khz. |

What are interlaced screen modes like? How bad is the flickering?
What is the monitor like as a PC monitor? These monitors are very very cheap in the UK for a 24" monitor. Under £150! |

How to adjust the picture to get square pixels, tho? Any controls to go 5:4?
Or do they (or others) do 5:4 monitors with the same scan support? Edit: The Swedish thread had some more replies - the HD one does support 4:3 (but presumably not 5:4, or the author would have mentioned it). Here's the HD one he bought: http://www.webhallen.com/prod.php?id...0&ref=Prisjakt Last edited by Photon; 02 November 2009 at 05:04. |

Hi AlexH, Photon, et al.
Quote:
Did a bit more playing around with it this evening. If I run the VGAOnly driver first, then DBLPAL and DBLNTSC now work. Multiscan productivity is also pretty good. When operating in 640x480 or 640x400 modes, it is possible to change the screen to 4:3 aspect ratio. Check the attached pic. Screen won't allow anything but 16:9 ratio's in any of the 15kHz modes, not that I am complaining! ---- As a PC monitor it's great. Normally I use this monitor as a second screen for my Macbook pro when doing coding/gfx stuff for the Mac. 1920x1000 crystal clear. My employer bought a load of them since they were so cheap!

Bummer, I dunno if I could live with a stretched screen when playing games.
What is the vertical height of the viewing area in mm? With it being a 24" widescreen monitor I want to compare size with my 20" CRT. |
