LS34C502GANXZA 100hz 100 hz missing

[TedFrimet]

Truly wonderful monitor. Unfortunately, it installed in a HP Envy I7 with generic driver in Windows 11 Home version. Locating the correct driver on Samsung and re-installing device driver was OK.

Despite installing the correct driver, I am unable to switch to 100 hz. It isn't available as an option under advanced graphics in Windows 11. The monitor supports the higher speed, HP supports HDMI 2.0, and I am using the HDMI cable supplied by Samsung. Yet I am stuck at 59 hz.

Any suggestions as to how to proceed would be great? i.e. power down, disconnect, reinstall, etc.

Is your graphics card updated? I read not all i7 monitors will support the 100hz, try windows key view advanced display options, there should be a way to choose from a drop down menu for refresh rate. If not , it's probably the hdmi cable that needs to be upgraded. Not really certain.

[TedFrimet]

Thank you. I am in the process of ordering a known good cable. That will probably work out. The drop down menu does not support 100 hz for the refresh rate.

The drop down menu only shows the refresh rates/resolutions your graphics card will support, not the ones it doesn't, so if it's not showing, your graphics card is not capable.  It's not the cable, it's the card.  Buy an add on graphics card or adapter -- internal or external, and make sure it supports your monitor's specs.

Although the replacement cable is on the way, I do agree that a graphics card would solve the issue. Thank You!

Recently the onboard graphics card on my 13 year old computer bit the dust. I, too, originally thought the VGA cable failed, and replaced that first and then realized the cable was not the problem. Since the motherboard is so old, you can't even buy a card to fit the slots, and my monitor has HDMI inputs, I bought a USB to HDMI graphics converter off Amazon, and it's been working perfectly. I bought this one specifically because it supported the resolution of my monitor. The 60 Hz refresh rate is fine for me, in 13 years I've never had a flicker. As a matter of fact, I didn't even realize 100Hz was a thing. I think that 60Hz is optimal, and video quality relies more on the resolution than the refresh rate. My monitor has a top refresh rate of 75Hz. My monitor was very advanced for its time (it has VGA, DVI and HDMI ports) and will still hold its own against any current monitors. Anyway, this is the one I bought, there may be others available that will support the refresh rate you want .

I am using the on-board graphics chip, and after swapping out the HDMI cable, I am certain that my HP Envy desktop does not support 100 Hz. Too bad, really. Graphics cards are expensive. You get what you pay for.

I'm not a gamer, so I don't need that high performance. However, if we are scrolling down thru an email, or lengthy list on a web page, 100 Hz would probably eliminate any possibility of screen jitters.

Can there be a recommendation for a least expensive card to support Display Port, and HDMI for an HP Envy I7 14 generation 20 cord, 16 GB Ram, with SSD storage ? I'd consider it a project, and the only solution, if I am going to get the best performance out of my Samsung monitor.

Of course, with performance comes additional energy requirements. On that note, keeping my refresh limits to 60 Hz would save energy, over the long term. So there's a benefit in maintaining status quo.

If you read my previous post, I offered a less expensive alternative of an external adapter.  As I said, it maxes out at 75 Hz, but there may be others on Amazon that will give you the 100. At least you will have a starting point.  Also, keeping the refresh rate at 60 Hz is much easier on the eyes for normal, every day tasking.  I would think the higher refresh rate works best for gaming. I think just normal use at 100 Hz will give you a migraine.

[TedFrimet]

Thank you for the advice on the migraine. No one wants that!

Your monitor will only get the maximum your graphics card will put out.  So as userella stated, make sure your graphics card is capable and, if not, swap it out.  If it's an integrated graphics board, just add an additional one and disable the main one.  A new GC will just become the primary video source (unless you select otherwise).
